How To Use The Electric Grass Trimmer

How to use a grass trimmer

With the onset of spring, vegetation appears on summer cottages and backyards of private houses, which must be dealt with. If this is ornamental vegetation, then it must be mowed with a lawn mower, and lawn mowers and trimmers are used to mow weeds and large thickets. These are prototypes of hand braids that require some skill to use. How to mow with a lawn mower according to the instructions, not many experts know. If you are asking such a question, then it’s time to understand the rules of Mowing.

Instructions on how to use a petrol trimmer learning how to start the tool

Before using the tool, it must be started initially. How to start a lawn mower, we will consider in detail. To begin with, the tool should be positioned on a flat surface so that the disc attached to the shaft does NOT catch on anything. After that, we proceed to start the engine of the lawn mowers:

    Initially, you should pump fuel into the starting system. To do this, press 4-5 times into the primer (soft hemisphere into the carburetor)

The above instructions for starting the engine of lawn mowers and trimmers are appropriate for a cold start. If a pause was made during the operation with the tool, then when restarting the engine that has not cooled down, it is necessary to close the throttle valve. You just need to turn on the ignition, and pull the starter handle.

Grass mirrors, its structure and principle of operation

A grass trimmer is a tool that works like a normal scythe but has a motor to rotate the cutting element. There are two types of trim tabs, depending on the type of this engine:

  • Lawn mowers powered by a gasoline engine, a distinctive element of their design is the presence of a fuel tank;
  • Motorized streamers with an electric motor, they are less bulky due to the absence of a fuel tank.

Electric braids, in turn, come with a mains power cable for connecting to the mains and battery.

Each of THESE trims has its own design features that affect the energy block. Otherwise, their device is very similar. Grass trimmers consist of the following elements:

  • The engine, which is located above or below, in the area of ​​the mowing head;
  • A bevel gear, installed only in models with a straight rod, with a curved rod as a connecting element between the cable (flexible shaft) and the trimmer head, The main bearing protrudes, consisting of two bushings;
  • An intermediate shaft located inside the boom of the powered scythe (the shaft is available only in a trimmer with a straight bar, in the hair with a curved bar instead of it, the rotation from the engine to the mowing head is transmitted by a flexible cable)
  • The rod itself, often of a telescopic type (which is convenient for adjusting the tool to the operator’s height) with a handle fixed to it;
  • Mowing head with cutting element;
  • Control panels;
  • Head protection cover.

In mechanized hair, a sharp fishing line (cord) is used as a cutting part, with any sectional shape, most often round or spiral. It is wound on a spool that is inserted into the bobbin, leaving two ends of the line free. It is these ends that the grass is cut off when the spool rotates quickly.

Instead of fishing line, other cutting elements can be used. plastic and steel knives and discs. The tool can be devices for using a cutting part of one or more types. This is convenient when you need to work with grass of different hardness.

The principle of operation of grass trimmers is quite simple. Rotation from the motor shaft is transmitted to the intermediate shaft or cable, connected to it on the splines. The other end of the shaft enters a bevel gearbox, which changes the direction of the axis of rotation, and forces the output shaft to rotate at high speed, on which the cutting element of the scythe is mounted.

In a curved bar trimmer, rotation from the engine to the cutting head is transmitted by a cable through a connecting piece consisting of two bushings.

Filling lawn mowers with petrol and oil

The tool must be filled with fuel before mowing with the lawn mower. Gasoline with oil is used as fuel. However, considering that it is only necessary to mix gasoline with oil for two-stroke engines. Four-stroke engines run on pure gasoline, since their design has a separate container. an oil sump. There is an oil sump in the design of 2-stroke petrol trimmers, therefore, only gasoline and oil should be poured into the tank.

It is recommended to use AI-92 fuel as gasoline. In order not to be mistaken in your choice, you need to read the instructions provided by the manufacturer. Often, most manufacturers recommend using AI-92 fuel, and only a few recommend pouring AI-95.

Gasoline must be diluted with small in a ratio of 1 to 25. This means that 40 ml of two-stroke oil must be added to 1 liter of gasoline. However, not everything is so simple here either. The proportion of 1 to 25 is universal, but there are different values ​​for each instrument model. These values ​​are also indicated by the manufacturer in the instructions. For more information on how to properly dilute gasoline and oil in a lawn mower, see here. After diluting gasoline with oil, fill the tank full, and start working.

How to make a trimmer with your own hands

The simplest electric scythe can be built from plastic pipes, a small electric motor and a battery from a conventional screwdriver. For this you will need:

  • A plastic pipe with a diameter of 40 mm of sufficient length to conveniently mow the grass;
  • Corner from a plastic profile at 45 degrees;
  • Plug for a plastic pipe with a diameter of 40 mm;
  • Adapter 40/50 mm.
  • Connecting wires.

To make the simplest battery trimmer with a lower engine location from THESE materials, you must:

  • Drill holes in the plug for installing the electric motor;
  • Fasten the engine to the plug, and solder the wires to it. Install the Assembled structure in the corner;
  • Drill a hole for the switch in a convenient place on the pipe. Pass the wires from the engine through the pipe and attach the corner with the motor to the bottom of it.
  • Install the switch button and terminals for connecting wires in series with the battery outputs.
  • Fasten the battery through the adapter to the pipe. It fits perfectly into a 50 mm hole.
  • From the blades of a clerical knife, a metal plate with holes and a bolt with a diameter equal to the diameter of the motor shaft, construct the cutting element of our trimmer. Attach this structure to the shaft using a wire clamp.
  • Cut out the protective cover from the plastic bucket and glue it to the corner with a hot glue gun.

A trimmer that is quite capable of cutting grass, even with a hard and thick stem, is ready. For ease of use, you can come up with a simple handle.

Let’s sum up

Grass trimmers are much more comfortable than Bosch lawn mowers in terms of their convenience, as these devices are more mobile and allow you to trim vegetation even in hard-to-reach places, for example, in a fence. Considering that trimmers, unlike lawn mowers, are quite lightweight and comfortable, the popularity rating of different models of THESE units is growing, and there are more and more fans of this method of mowing grass. Choosing a trimmer for a home garden involves considering many approaches, but in the end, a person can get a multifunctional device. It is better to choose a trimmer “by hand”, as in this case it will be easy and convenient to mow.

Step-by-step instructions on how to mow the grass with a lawnmower with a disc and save fuel

It is required to start the lawn mowers mainly on the ground. Some craftsmen know how to wind up the instrument, holding it in their hands, but this is quite difficult and dangerous. After launching the tool, you can start using it. First, you should put on protective uniforms and an unloading belt. Depending on the model of the tool, the unloading belts can be on a carabiner or ties. If a carabiner or latch is used, then after starting the engine, the tool should be secured and started to work. If ties are used, then you need to put on the belt along with the working tool.

The belt should be balanced first. This means that despite the total weight of the tool, the mower’s hands should have a minimum load. With his hands, the mower only moves the tool, and if you do not balance, then there will be rapid fatigue during work. The entire weight should be borne by the worker.

When the tool is ready for use, the lawn mower slope instructions are as follows:

  • You need to make movements to the right and left Take your time, while holding the trimmer at the same distance from the ground
  • The mower’s movements should be unhurried (half a step). Experts call the movement of the mower duck steps
  • The biggest challenge newbies face is keeping the RPM steady. The turnover during the mowing process should be changed, depending on the density of the vegetation. If the grass is young, then it does NOT require full power to cut it.

Often among KoSaRei lawn mowers there are disputes about how to mow with a trimmer correctly, whether it is necessary to release the gas or whether it is better to work in a constant mode. We will understand these issues in detail.

  • There is an opinion that it is better to mow with a lawn mower in one speed mode. This opinion is NOT correct. Working with the same power Not only does it increase fuel consumption, but also worn parts. Venting the gas during the reverse movement of the tool is useful, since during this period the motor cools down, as well as lubrication of the CPG. Gas discharge leads to the overlap of the throttle valve, as a result of which the fuel passes through the XX channel, and thereby lubricates the parts
  • Gas discharge allows not only mowing the grass, but also neatly placing it in swaths. Moving the tool in one direction allows you to mow, while the reverse movement creates a roll
  • The disc only moves in one direction, so it just makes no sense to keep the tool at constant speed when moving in the opposite direction.
  • Throttle release causes the cutting disc to coast to the crankshaft, and coasting is always beneficial

The line also has its secrets

“Data-echo =” https://storgom.ua/uploads/gallery/I/444.Jpg “width =” 100% “/

The line is wound on a spool inside the spool, with the tip exposed outward. When mowing, the spool rotates, and the line, with this rotation, cuts the grass. To release the ends, you need to lightly hit the coil into the ground (semi-automatic system), there are automatic reels in which the fishing line is released itself. There are also a few rules when working with fishing line:

In order not to damage the line and reel. Try NOT to touch the spool and line with various hard materials. tracks, curbs, fences. This will shorten the line prematurely, damage the reel or even jam the engine. Spool with line must also not touch the ground.

Cut with the Tips is more effective. Cutting the full length of the line may overload the engine. It also lowers the mowing efficiency. The tool must be held so that it only mows with the ends of the line. To do this, tilt it forward. towards Mowing.

Tall grass requires several mows. If the grass is above 20 centimeters, then one mowing will cost here. You need to mow two or three times, from top to bottom. This is to prevent the grass from wrapping around the reel. Wound grass. this is ensured overheating of the engine. If the grass is still wound, you need to stop the tool and clean it.

The line ran away and hid in the reel. This option happens when you work if you DO NOT release the line from the reel in time. After all, the line is erased and shortened during mowing. If you do not have time to release it, then stop the engine, Unplug the tool from the mains, and then disassemble the spool and pass the tip of the line into the desired holes.

What determines line consumption? It must be remembered that the line wears out faster if the grass is tough. Therefore, it is necessary to release it more often when mowing weeds and dry tough grass. Around the foundation of the house, near the wall and the curb, the line consumption will also be higher than directly on the lawn or near the trees. It is worth considering: if you work carefully and accurately, then the consumption of the trimmer line will be optimal and economical.

Selection recommendations

Let’s summarize. The right trimmer can be used for years. But for this you need to decide what tasks the device will solve (what vegetation you plan to fight), and what characteristics it should have.

For moderate occasional use, models with built-in battery and stainless steel blades are suitable.

In this case, it is not necessary to be puzzled by the need for additional functions. Such trimmers can be purchased in a fairly wide price range, which depends on the tasks solved by the device, the manufacturer’s popularity and the potential reliability of the design. Choose according to your budget. To save too much is not worth it. Remember the saying about people who pay twice.

If you plan to use the trimmer in the shower or wash it underwater, pay attention to the moisture protection function. In this case, for example, such models will suit you.

Need an “advanced” uncompromising device, since you’re used to the very best? The flagship of the trimmer world is your choice.

Safety engineering

In order for the use of the trimmer to bring only positive emotions, both after mowing and in the process of work, you should follow the urgent safety recommendations.

  • Mows better in dry weather.
  • Operator’s arms and legs Must be covered with long sleeves / legs. Open shoes Better not to wear.
  • You need to wear special glasses Small debris and scraps of grass can injure your eyes.
  • If there is a lot of noise, you should use earplugs.
  • It is better to hold the cutting attachment with the cover towards you.
  • Hand and foot tray to the head of the included device cannot be!
  • Necessary Observe the position of the wire: it must be behind the operator.

So, the variety of trimmer models on the market makes it easy to find the best trimmer for every need. Despite the presence of petrol-powered lawn mowers, electric models lead the compact mowers rating. This speaks to the desire of consumers to avoid the hassle of refueling the tank. Caution should be taken when using the AC / Battery trimmer due to the potential for short circuits.

How to Lubricate the Electric Trimmer?

From time to time the tool needs to be Lubricated. Experts advise to do this every 10-15 hours. Operation of the device. Here’s how to do it:

  • The electric lawn trimmer is equipped with a technological hole in the upper part of the housing, where the gear block is located. You need to find him.
  • Unscrew the screw, which serves as a plug in the hole.
  • Introduce 1.5-2 ml of a thick consistency into the cavity.
  • The shaft is turned by hand several times to make sure that it has penetrated into all parts of the gearbox. the flywheel, the starter coil pawl and the bearings.
  • Before preserving electric braids for the winter, clean and wash the gears of the reducer, remove the old grease and apply a new one. We take care of the tool, you can significantly extend its service life.

Filling lawn mowers with petrol and oil

The tool must be filled with fuel before mowing with the lawn mower. Gasoline with oil is used as fuel. However, considering that it is only necessary to mix gasoline with oil for two-stroke engines. Four-stroke engines run on pure gasoline, since their design has a separate container. an oil sump. There is an oil sump in the design of 2-stroke petrol trimmers, therefore, only gasoline and oil should be poured into the tank.

How to attach a disc or line to trimmers

The cutting tool is attached to the executive body. The attachment point is called the gearbox. It is not difficult to cope with the task of installing a disc or coil. The principle of attaching the cutting discs to the trimmer is as follows:

How To Use The Electric Grass Trimmer
  • Initially, the shaped washer is fixed by using a hex wrench
  • Install the disc on the shaft
  • Then install the upper washer, then tighten it with the fastening nut
  • It is necessary to rotate the nut using a special socket wrench, which is usually completed with each tool
  • Nut rotation is counterclockwise
  • When rotating, it is necessary to jam the shaft with a hex wrench

In the opposite sequence, the disc is removed and replaced with a trimmer. For more information on how to attach a line reel to your lawn mower, see this resource.

Trimmer setting

Before starting work with the trimmer, you need to perform a number of preparatory steps.

  • Assemble the unit, lubricate the gearbox (if any), adjust the length of the rod and the position of the handle.
  • The gasoline appliance must be filled according to the instructions, check the condition of the fuel and air filters.
  • The trimmer must be connected to an earthed socket, the cordless tool will fully charge.
  • Line with a suitable diameter should be wound around the bobbin in advance.
  • If you have to work with other attachments, they need to be inspected for damage, carefully check the sharpness of the blades and secured to the working head.

Which attachment to use for lawn mowing

Lawn mowers use two types of cutting attachments or cutters. These are reels of line, as well as steel or plastic discs. What is better to choose for the work of a gasoline tool. The site provides information on how to choose discs and line for trimmers, as well as their types and design features. Let’s take a quick look at what types of cutters should be used on trimmers and lawn mowers.

  • For cutting soft grass, a fishing line is used, which is wound on a drum or reel. The fishing line, unlike metal discs, is used where the grass grows next to trees, houses, fences and other obstacles. The fishing line allows you to make high-quality grass slopes near obstacles, while NOT violating the design of the tool
  • Metal knives. have 2, 3, 4 or more cutting parts, through which the slopes of rough grass and thickets are carried out. Practice shows that the thicker the mown thickets, the more blades the cutter should have.
  • Metal discs with fine teeth in the amount of 40-80 pieces. designed for cutting various vegetation. It can be rough grass, weeds, dense thickets and even small trees. The greater the number of teeth on the cutting attachment, the higher the efficiency of the tool in question.
  • Plastic discs. used primarily on trimmers or cordless lawn mowers

The choice of cutter depends on the place of use of the tool. If you plan to work in the Homestead territory, then a fishing line is chosen, and for cutting grass in a field or steppe, discs with 3-4 blades or more, as well as discs with fine teeth are used.

It is interesting! In most cases, cutters are NOT supplied with a tool, so the buyer can independently decide what he needs. a line or a steel disc.

Operating rules

For diverse tasks and volumes of work, they use fishing line of different diameters: 1.5-2 mm. for mowing the lawn, up to 2.7 mm. for dense wild-growing grass (for example, on roadsides), 3-3.3 mm. for heavily overgrown area where tall grass, thick-stemmed weeds, small shrubs grow. It is better to use a disc for mowing and harvesting stiff stems and large bushes. They also conveniently mow dense thickets of tall grass, especially if you need to cut the shoots at the root.

The cut width of the trimmers is 20 to 42 cm. In one pass, you need to make one movement from right to left or two or three. from side to side when mowing tall grass and weeds. The Swath area is associated not only with the size of the cutting surface, but also with the physical data of a person: the wider the attempt, the more grass is mowed at one time.

When using different types of trimmers, there are strict limitations:

  • Trimmers cannot be used in wet weather;
  • Machines with a lower motor position must not mow wet grass;
  • Lawn mows can be turned on in bad weather only if permitted by the manufacturer, since the devices have different degrees of protection against moisture;
  • Drops falling on the body should be wiped off, a wet device must be turned off and dried;
  • Store trimmers in dry rooms.
