Assembling and tensioning the chain

The G-Max 40V GreenWorks GD40CS18 cordless chain saw assembly process takes minutes. First of all, it is necessary to remove the chain cover, for this purpose it is necessary to unscrew the two fixing nuts.

Next, you need to install the chain on the bar so that the chain guide links fall into the guide groove. The chain must be installed in such a way that the teeth are directed in the direction of rotation of the chain.

The next step is to install the chain on the sprocket, after making sure that the loop of the chain extends beyond the bar.

Next, you need to install the bar on the saw, making sure that the hole for tensioning the chain on the bar is aligned with the bolt, after which it is necessary to install the chain cover in its place.

Do not immediately tighten the nuts securing the casing. At this stage, the chain is tensioned. For these purposes, it is necessary to remove the chain brake and make several full turns of the chain forward / backward, making sure that the guide teeth are in the groove on the bar.

Further, by turning clockwise, using a screwdriver, it is necessary to tighten the chain until the “belly” disappears.

After that, you can tighten the nuts fixing the plastic cover.

Then you can install the battery until it clicks into the battery compartment. It is imperative to make test cuts, and then re-verify that the chain tension is correct.


The body of the device is made of light green, matte, impact-resistant plastic, while there are glossy black plastic inserts and rubber pads.

GreenWorks GD40CS18 has a classic chain saw design. At the back of the device there is a handle, covered with rubber inserts, which provide a more secure grip and prevent the device from sliding in the hand. In the upper part of the handle there is a trigger switch, to the left of which, at the end of the handle, there is a fuse (lock-button).

At the bottom there is a sticker with warning pictograms.

On the front surface there is a metal baffle with spikes, as well as a measuring scale for the oil level.

When looking at the device from above, you can see the battery compartment, which houses the Greenworks G40B2 40 volt battery. There is also a curved front handle made of a fairly soft, pleasant to the touch black plastic, as well as a front protective handle that acts as a chain brake.

On the left side there is a row of ventilation holes, the name of the manufacturer, information that this device belongs to the GreenWorks G-MAX 40V line, as well as the oil tank cap.

On the right side there is also a GreenWorks logo and information that the device belongs to the G-MAX 40V line. There are also two fastening screws that secure the removable plastic chain cover, as well as a chain tension bolt.

By removing the black plastic chain cover, we gain access to the tire landing mechanism and sprocket.

The base of the chain saw is completely flat, making it an excellent fit on a flat horizontal surface. In the front part, near the engine compartment, there are ventilation holes.

The tire is made of metal, there is a guide groove at the end, the GreenWorks logo is located at the ends, as well as information that this tire is 16 ”(400 mm). The tire is provided with tire tension holes, and an oil supply hole.

Separately, I would like to mention that the device is equipped with a bus and a chain from Oregon.

The body of the charger is made of impact-resistant plastic, most of which is painted light green. It contains a contact block with a locking mechanism for rechargeable batteries. Here, on the upper surface, there are two LED indicators:

  • mains power indicator;
  • battery charge indicator.

Also on the case there is a sufficiently large number of ventilation holes to remove excess heat from the device case. There is a power cord at one end.

In addition to the ventilation holes, the bottom cover, made of black plastic, has four rubber feet that securely fix the charger on the horizontal surface of the table, and there are also two elements for fixing the charger to the wall. For the convenience of the user, the center distance is indicated on the case, for installation.

The battery housing is also made of impact-resistant plastic, painted in light green color. For a more secure grip, rubber pads are provided on the body.

On the front surface there is a four-position LED indicator of the battery charge level, which is activated using a special button located to the right of the indicators.

  • Charge level 10%;
  • Charge level 45%;
  • Charge level 70%;
  • Charge level 100%.

There is also a spring-loaded button that allows you to open the device fastening lock, as well as four fastening screws that fix the front cover of the device.

On the side surfaces there is a number of informative stickers, which contain basic information about the device, as well as the name of the model and battery capacity.

On the upper surface there is a lock with guides, as well as a contact group of batteries.

According to the manufacturer, the battery consists of cells produced by the Japanese company Panasonic, and is equipped with a control board that ensures uniform charging and discharging of cells, while the device is equipped with a special chip that is responsible for protecting the device from overcharging, overheating and deep discharge, which significantly increases battery life. The manufacturer says that the number of charge-discharge cycles of the battery can reach 1500, which is approximately equal to seven years of operation.

A charger equipped with a redundant overcharge protection chip can fully charge a 2 Ah battery in 60 minutes and a 4 Ah battery in 120 minutes.

In work

The GreenWorks GD40CS18 electric chain saw is a tool that requires extra care and safety. The first step is to hold the instrument correctly. With your right hand, hold the saw by the rear handle so that your index finger is under the trigger, and it is convenient to press the safety catch with your thumb. With your left hand you need to hold the device by the front handle, grip from above.

After the battery is installed in the device, the chain saw is completely ready for use. To start the device, it is necessary to remove the chain brake, hold down the side safety button, and then press the start trigger.

How To Cut Firewood The Old-Fashioned Way

The method of working with the tool is described in sufficient detail in the instruction manual. How to hold the device, how to make cuts, etc. all of this can be found in the instruction manual.

In our particular case, the GreenWorks GD40CS18 cordless chain saw was purchased for work on a personal plot, cutting firewood for a stove, barbecue, pruning branches and, of course, for use with small outings in nature.

The device was not planned to be used for a long period of time (for example, for sawing a large number of logs, for firewood), for this reason a 2 Ah rechargeable battery was purchased for the device (there are batteries with a capacity of 2, 2.5, 4 and 6Ah on sale, which in can significantly increase the autonomy of the device).

When testing the device, several test cuts were made. When testing, a beam of 100×100 mm and several dry branches were used. The air temperature outside over the past few days was 24 ° С.

Beam 100×100 mm. With a fully charged battery, 20 cuts were made, after which the battery charge level, according to the indicators located on the device body, decreased by ¼. At the same time, I would like to note that the device easily sawed the timber, despite the fact that in some places there were quite large knots. The GreenWorks GD40CS18 chain saw allows you to make a fairly even, not wide cut.

Branches of a dry tree. Next, the branches of a dry tree were cut, the diameter of which ranged from 60 to 130 mm. The branches lay on the street for a long time, time, they froze. At the same time, the saw carried out sawing with the same ease, leaving behind a relatively thin and even cut. When sawing trees, it is very important to choose the correct cutting direction to avoid the chain and bar getting stuck in the trunk (which happened with one of the test saws). The instruction manual contains schematic illustrations and recommendations for the correct use of the tool.

In the process of sawing branches, about 15 cuts were made, after which a dozen more cuts of a 100×100 mm bar were made. At the end of the test, the battery charge level was 50%.

Of course, the battery capacity will not be enough for long-term operation, but the GreenWorks GD40CS18 chain saw model is not intended for this. As mentioned earlier, this is a tool for household needs, which is perfect for working in the country, on a hike, fishing.


  • Build quality and quality of materials used;
  • Excellent autonomy of the device (the ability to select the battery capacity to suit your needs);
  • Device power (equivalent to an electric saw of 1.5 kW.);
  • The chain speed reaches 20 m / s;
  • DigiPro brushless motor;
  • Low weight of the device;
  • Lack of exhaust gases when working with the device;

Battery chain saw G-Max 40V GreenWorks GD40CS18. for summer cottages, for hiking, and for fishing.

Choosing a cordless chain saw is a difficult task. First of all, you need to understand that many underestimate a cordless tool, especially such as chain saws, hammer drills, etc., saying that a serious tool cannot be cordless. In principle, there is some truth in this, because at the moment no battery tool can be compared in power with a gasoline or electric one. That being said, cordless tools definitely occupy their niche as standalone and eco-friendly tools.

Today’s review is about the GreenWorks GD40CS18 cordless chain saw.


  • Lack of battery and charger in the basic delivery set;
  • A wrench must be used to tension the chain and change the bar (old system).

Types of devices and attachments for cutting logs

It is possible to cut the harvested trunks at home only if the owner of the site has a device for a chainsaw for sawing logs or a special metal attachment for a garden tool. It is easiest to install a proprietary attachment on the chainsaw, however, in this case, the operator will not be able to get perfectly flat boards.

You can get better and smoother boards if you equip the nozzle with a guide and a retainer that will hold the workpiece. To do this, you will need to install a metal frame on the tire of a gasoline saw, which can be welded from the legs of an unused school desk. In this case, the distance between the frame and the tire must be made adjustable. this will allow the operator to cut wood into boards of different thickness.

If the used chainsaw will work in a stationary mode, then a guide for high-quality uniform cutting of logs can be quickly made from a prepared metal profile or polished wooden blocks using drawings for this. The ends of the guide used will need to be fixed on the trestle. In this case, the wood will fit under the resulting structure, and the procedure itself will be performed quickly and without unnecessary physical effort.

The device for sawing logs with a chainsaw made in this way can only be used for working with not too long trunks. This is because the weight of long, heavy trunks will cause the guide to bend, resulting in uneven cutting of the wood.

Device for sawing logs

Sawing logs is a procedure without which it is impossible to obtain high-quality and perfectly flat boards. This type of work can really be done at home, having at hand a powerful chainsaw and a special hand-made device.

The procedure for longitudinal cutting of a forest with a chainsaw

Perfectly flat boards can be obtained by using a balanced guide ruler to cut the log. It is often referred to as a special guide or straight pattern. It is originally a metal machine used to cut wood regularly. If the work on the longitudinal dissolution of wood will be performed rarely, then it is unprofitable to buy such a device.

Both branded and homemade wood rip saws work on the same principle. A special chain is used for work. Finding it is quite difficult, so many owners of chainsaws use a regular chain instead, the teeth of which are carefully sharpened at an angle of 10 ⁰. The only negative is the rapid wear of the chain teeth.

The procedure for longitudinal sawing of harvested trunks is as follows:

  • First you need to take 2 strong, perfectly straight boards and connect them to each other at a right angle. Thus, the operator will receive a stable forward pattern;
  • Then you need to make stops, to create which you can use wooden blocks. The resulting stops will need to support the previously made straight template;
  • Next, the tree trunk will need to be laid on a homemade device;
  • After that, you need to fix a pre-made frame on the bus, and also attach supports to the ends of the used log that support the installed leading ruler. The second procedure requires horizontal installation;
  • All elements used for assembly must be fixed with self-tapping screws;
  • Then you need to attach a template to the supports, and also adjust it in height. It should be borne in mind that the log will be cut approximately 1 cm above the level of the ruler;
  • After that, you need to turn the log, start the chainsaw engine and make the first cut.

Next, you need to remove the fasteners that hold the wood and fix the template used on the sawn surface so that it is directed towards the second cut. The supports of the ruler itself can be fixed at the ends or directly on the surface of the log. After that, you will need to make a second cut. it must be perpendicular to the first.

In subsequent stages, the guide metal ruler can be dismantled. in the future, one of the cut sides of the barrel used will perform its functions. The operator will need to adjust the thickness of the wood cut and cut the trunk so that the bark on the resulting bar is only on one side. After that, you need to turn the trunk again, and also adjust the thickness of the cut. The operator must then make the final cut and obtain boards of the required thickness. If it does not play a special role, then you do not need to adjust the trunk for the harvested timber. In this case, independent sawing of logs with a chainsaw into boards is performed only up to the middle of the workpiece, then the log unfolds it exactly 180 ⁰, and the sawing continues on the other side of the trunk.

Features of cross-cutting of logs

Sawing a log lengthwise is a rather laborious process. Therefore, many chainsaw owners prefer to cut tree trunks in the cross direction. In these cases, it is possible to obtain discs, and already from them to cut flat boards of different thicknesses. In the future, the finished wood can be used to make benches and other garden furniture.

To cross-cut logs, proceed as follows:

  • First, the trunk will need to be installed on the trestle, at least 80-90 cm high;
  • Then the trunk will need to be cleaned of bark;
  • Next, you need to make a small cut, which will play the role of a guide groove;
  • After that, the used log must be turned 90 ⁰. In this case, the tire of the garden tool must cut strictly in the direction of the intended groove.

It must be remembered that when performing both longitudinal and cross-cutting of a log into boards, there is a high risk of injury. Therefore, both types of work must be performed in compliance with all safety standards. The operator must wear gloves, goggles, anti-slip footwear, and a suit made of thick fabric. When cutting a log, you need to stand a few meters from the bar, as the chain can break off at any time and harm the operator and people around him.

Hand saw for wood. the secrets of selection and use

Currently, both in home workshops and in production workshops, various tools are widely used for cutting wooden beams and boards, cutting slabs, which are also based on wood processing products. These are hand-held circular, band and reciprocating saws for wood. All of them are electric, that is, their working part is driven by an electric motor of the required power.

With all the indisputable advantages of hand-held electric saws for wood, they also have a number of negative features:

  • dependence on sources of electricity;
  • low degree of mobility;
  • exactingness to the experience of the employee using them;
  • high cost of both the tool itself and its consumable parts, associated repairs and additional equipment.

Very often the amount of woodworking is small or very rarely done. And buying for them, for example, a hand-held electric circular saw for wood is an expensive undertaking.

  • The use of a hand tool resolves all contradictions and allows you to overcome the disadvantages of power tools for wood.

Of course, you can buy a very cheap power tool, but then there is a threat to the safety of the worker himself and the guarantees of obtaining a quality product completely disappear. It seems that this situation is hopeless, but it is not.

A way out that resolves all the contradictions and allows you to overcome the disadvantages of power tools for wood is the use of a hand tool. First of all, it is a hand saw for wood.

Structurally, a hand saw consists of:

In all types:

  • Metal strips of a certain length with teeth on one of its sides;
  • One or two handles made of metal, wood or plastic;
  • Mounting screws to attach the saw blade to the handle. On the latter, for this there are special recesses or holes.

In some forms:

  • backing. a special metal stop, at the same time giving greater rigidity to the saw blade.
  • bow machine. a metal or wooden frame on which the saw blade is fixed.

Type 5: Reward

Otherwise called a hacksaw-reward. In shape, it is a modified butt, the handle of which was transferred directly to the butt. The purpose of this type is the precise processing of tenons and grooves. Using this tool eliminates the need for a manual electric router, but requires a lot of practical experience.

Type 4: Bow

In its simple execution it justifies the name. It looks like a bow with a thin and long saw blade instead of a bowstring. The frame of this saw can be made of wood or metal. The bow saw is often equipped with a blade tensioner.

In general, this type of saw is a hand-held analogue of a band saw or, in some cases, a circular saw. It is worth using onion in cases of a single, sporadic use. That is, when buying an expensive band saw machine is not economically justified.

Type 1: Classic

This type is the most common and is found in both amateur and professional workshops. The length of the saw blade can fluctuate around 50-60 cm. Often these saws are equipped with a quick-change mechanism for the saw blade and can be used quite easily for a variety of jobs.

Often these saws are preferred by amateurs. The disadvantage of these saws may be the low quality of workmanship. the blade may not be firmly fixed. This reduces the accuracy of cutting the workpieces. But an indisputable plus is the rather democratic price of this tool.

How to choose a saw

The specific type of saw is selected depending on the tasks to be performed. You need to pay attention to the following characteristics that any hand saw for wood has:

  • the size and shape of the teeth;
  • type of steel;
  • saw blade length;
  • shape and material of the handle.

Size, number and shape of teeth. In short, all types of teeth that a hand saw for wood can have are combined into three groups:

  • for longitudinal sawing, that is, along the wood fibers. In shape, these are beveled triangles, sharpened on both sides.;
  • for transverse. across the fibers. The teeth in this case are equilateral triangles;
  • universal. for them the direction of the fibers does not matter. The teeth of the first two types are combined here. In addition to this, they are collected in small groups, separated by special notches.

For modern saws, there is a special TPI indicator, which is reflected in the tool passport, and means the number and size of teeth per inch of the saw blade. The higher the indicator, the more accurate the cut is given by such a tool.

  • Accuracy is inversely related to speed and effort. This must be taken into account in advance when starting work and choosing a tool. For example, if it is supposed to work for a long time, you need to give preference to a tool with a more comfortable handle, equipped with high-quality damping rubber inserts. This will save you from calluses on the palm and from overloading the ligaments of the hand and wrist.

In their shape, the teeth are as follows:

  • “Wolf’s Tooth”. used for sawing raw wood.
  • “Jet-kut”. this is the name of the union of six set dagger-shaped teeth with two of the same undivided.
  • “Japanese tooth”. used in Japanese hand saws for wood. It is distinguished by a reverse wedge shape and the uselessness of wiring as a result.
  • “Simple dagger tooth”. has the shape of an equilateral triangle (this allows you to cut and counter movement), the setting is done every third of the thickness of the canvas. Saws with these teeth are designed exclusively for cutting wood across the grain. This tooth is widely found on hacksaw and bow saw blades.
  • “Tooth-chisel”. so called because of the sharpening of its top transversely relative to the blade. The shape is a beveled right-angled triangle. Such a tooth is used exclusively for cross-cutting wood with award-winning hacksaws and back saws.
  • “Universal tooth” is a synthesis of simple dagger and chisel teeth. Has a sharpened leading edge. Because of this, a saw with such teeth is very versatile with respect to wood fibers. This tooth type is used in all circular saws.

Steel type. Most often, hand saws are made from low carbon steel. This makes the web sufficiently flexible and elastic at the same time. The teeth on these saws can be sharpened independently. Most durable stainless steel saws.

Of course, you need to remember that stainless steel can also be destroyed by rust if the storage and operating conditions are violated. Recently, hardened tooth saws are gaining popularity among DIYers.

For sporadic work, this is an advantageous solution, since they hold the sharpening well. But they have a significant disadvantage. after grinding, the teeth cannot be restored at home. In fact, such a saw is disposable.

Saw blade length. According to this parameter, all saws are divided into three groups:

  • mini. their length is not more than 35 cm.
  • universal. length from 36 to 55 cm.
  • wide (large). blade length more than 56 cm.

The shape and material of the handle. They are quite diverse and depend on the type of work performed. They can be quite minimalistic (as, for example, in Japanese wood saws) or have a very comfortable anatomical handle that protects the hand.

Previously, the main material for the handles was wood. Now it has lost some of its positions to metal, plastics and rubbers. Which of them to give preference depends on the type of planned work, their duration, available budget.

Drank varieties

Type 2: Narrow

She’s a circular hacksaw. Medium length, pointed towards the end and not removable. It is a manual alternative to an electric jigsaw. It is convenient to carry out complex-profile cuts in sheet materials such as plywood, fiberboard, chipboard and the like. There is a version of this saw for working on drywall.
