How To Adjust The Trimmer

In order for the area near the house to always look well-groomed and neat, it must be cut regularly. Fortunately, modern technology allows you to solve this problem without excessive physical effort. Electric trimmers are so easy to use and maintain that even a teenager can mow with them. The main thing is to figure out in advance how to fill the line in the trimmer.

How to load the line into the trimmer?

So, we are faced with a task. Correctly load the line into the trimmer. Let’s take a closer look at what it will start with and what pitfalls can await us in the process.

Step 1. Choosing the line

Step 2. Remove the coil from the trimmer

To perform this operation, the trimmer must be disconnected from the mains and turned over with the working head up. The further course of action depends on the trimmer model and the design of the coil itself:

  • In small trimmers with a lower engine location, press on the keys located on the sides of the coil and remove its upper part from the head;
  • On a trimmer with a curved rod, the coil body is clamped with one hand, while turning counterclockwise the thumbs located on the body;
  • In trimmers with a straight bar and a gearbox, insert a screwdriver into the hole located under the coil, and then turn the coil body counterclockwise.

Step 3. Disassemble the coil

After the coil is removed from the head, it must be carefully disassembled. It is better to do this on an already mown area, since there may be a spring inside the coil, which will be quite difficult to find in tall grass. After disassembly, we will have three parts on our hands: the body (top cover), the protective casing and the coil itself.

Step 4. Measuring the required amount of line

Newbie mowers are usually interested in how many meters of line to wind on the trimmer reel? There are two ways to resolve this issue:

  • Unwind a skein of line on a flat, dry place and separate half of it.
  • Measure 3-4 meters of line from the skein.

In any case, after the end of the winding, the turns of the line should be on the body of the reel, and not sliding off it. You do not need to try to wind as much as possible, as the line will unwind poorly and often break.

Step 5. Winding the line onto the reel

How to attach the line to the trimmer depends on the coil design. Consider the option when the coil body has one outlet for the line. In this case, the end of the line is clamped in the crevice of the reel, and then we wind the line, trying to lay the turns as tightly as possible. The direction of laying the turns should be opposite to the direction of rotation of the coil and is usually indicated on its inner part. After the end of winding on the spool, you must put on a protective cover and bring the end of the line into it

If the reel is designed to work with two tails, then the line must be folded in half and laid in the groove in the center of the reel. Further winding will be carried out along one or two slots, depending on the coil design. The direction of winding must also be opposite to the direction of rotation of the coil. At the end of the ponytail, the line will also need to be led out into the holes on the top of the reel.

Intake control lever is sticking

The adjusting lever is stuck. The consequence of its incorrect installation, accidental bending. The contacting face will get the wrong position. This will disrupt the additional injection of gasoline.

Malfunctioning fuel pump

The most repetitive breakdown. Diaphragm wear, rupture. As a result, its non-fit. The fuel passages are NOT sealed at certain stages in the engine cycle. The reasons are as follows:

  • You have been working on lawn mowers or trimmers for too long without interruption;
  • Fueled with low-quality fuel;
  • Waste gases enter the pulse channel.

A deformed membrane is fraught with several bad consequences:

  • There is not enough gasoline or oxygen in the generated combustible mixture;
  • The motor starts after 10 or more unsuccessful attempts;
  • The engine knocks, clinks when running, etc.;
  • Working piston is deformed.

As a result, the inner space of the fuel pump is contaminated from the side of the impulse channel.

The inlet needle is broken

The inlet needle breaks due to metal and stone particles in the gasoline. As a result, the seat of the intake needle does not fit tightly against it, the fuel mixture flows. There is too much air in the fuel mixture created by the carburetor, causing the engine to sneeze in progress. Finally, the needle may get stuck due to low-quality gasoline, or the unit has been idle for a long time.

Carburetor device

The lawn mower (lawn mower) contains the base. The body is made of aluminum, in which the rest of the parts are placed, working harmoniously as a whole. There is a diffuser in the carburetor body. Stroke with internal channels, through which air is pumped.

Channels branching off from the diffuser stroke deliver fuel, with which the forced air mixes, entraining gasoline vapors. Outside the main carburetor compartment are located:

  • Jets;
  • Mini fuel pump;
  • Unit regulating the mixing of fuel with air.

The latter forms the very explosive mixture ignited in the carburetor combustion chamber.

  • Adjusting the carburetor on lawn mowers

A lawn mower or trimmer, despite its relative simplicity (compared to a car engine), sooner or later fails. There comes a time when long downtime and restart of the gasoline unit cannot be avoided. Service needed. In advanced cases, repair is required, or rather, replacement of worn-out parts with the same new ones. Until you are faced with the need to replace your worn parts, carburetor maintenance is required. Cleaning, flushing, reconfiguring devices.

Adjusting the shoulder straps

To distribute the load evenly across the shoulders and back, the shoulder straps need to be well adjusted. To do this, just tighten or relax the straps. They should NOT bite into the body or the hang. You can understand how the weight will be dispersed if you press the hook for hanging the braid with your own hands.

Balancing the handles

An important step in adjusting the backpack belt is also adjusting the handles to the optimum level. When the operator is holding the lawnmower, his arms should be relaxed and his shoulders should be parallel to the body. Therefore, after adjusting the two-shoulder strap, adjust the two-hand mechanism by moving it up or down. It is necessary to achieve such a result that the hands only set the direction, and not hold the device. If after that the trimmer balancing is disturbed again, you will have to repeat all the steps again.

Hook height adjustment

The most important thing. Adjust the strap so that the trimmer is at the correct level from the ground. To do this, raise or lower the height of the hook, which is done by tightening the shoulder straps until the holder is 10-15 cm below the hips (palm width). In this case, the knife of the attached braid should be parallel to the surface, that is. In a strictly horizontal position.

By balancing the braid by moving the ear

After fixing the required height for yourself, you need to balance the trimmer. For this, the eyelet is rearranged, with the help of which the device is suspended from the belts, forward or backward. As a result, you need to attach the strap to the trimmers so that when you release the steering wheel, the knife or saw blade does NOT fall on the ground, but hangs over it, NOT touching the surface. At what distance it will be located depends on the goals set.

What is a backpack strap

It should be understood that the weight of a filled lawn mower is on average 6-9 kg. And this device must be kept suspended all the time. To evenly distribute the load, the backpack strap seems to encircle the body from all sides. The main load falls on the shoulders and back, so the upper part of it is supplemented with wide foam inserts and fabric shoulder straps. Further, the straps are lowered along the body and, with the help of a quick-release clip, are connected to each other in the chest or abdomen area. And so that the belt does not cut into the body during load, a wide and durable lining is provided. A plastic leg guard is attached to the belt. It has a carabiner for attaching to the trim tabs and spring cushioning. The ease of unfastening and fastening the lawn mower is provided by a quick release latch located on top.

Safety regulations

Among the safest and most popular trimmers, products of German manufacturers (including Denzel) are especially appreciated, since they pay increased attention to quality and reliability. However, despite the brand and model, there are a number of rules that you need to clearly know and follow when using the trimmer.

  • Before use, it is necessary to read the instruction manual.
  • You can not work with the trimmer in a state of fatigue, illness, intoxication.
  • It is forbidden to use the scythe in explosive and fire hazardous areas.
  • You cannot mow during a thunderstorm and rain, as well as after rain, when the grass is wet.
  • You can work only during daylight hours, in good lighting conditions.
  • Use only the type of fuel and lubricant that is suitable for the particular trimmer model.
  • It is not recommended to repair the instrument yourself.
  • Do not touch rotating or heating elements during operation.
  • No smoking and no fire during the mowing process, etc.

If you still have questions about the adjustment on the backpack belt of a particular lawn mower model, you can try to find the answers in the instruction manual attached to the product or look on the Internet, where it is clearly and easily shown how to adjust and adjust the belt together with the lawn mower.

Mowing tall grass

If it is necessary to cut the Tall grass, this is done in several passes. The lawn processes in 2-3 times. The rotating part is lowered from top to bottom, in this case the grass does not wind up on the reel.

The operator should be aware that grass wrapped around the reel will overheat the motor. If this happens, the mower is turned off and the coil is Cleaned.

Mows grass most effectively with the ends of the line, not the entire length. In the second case, the tool works worse, the motor may be overloaded. If you need to cut grass over a large area, tilt the trimmer towards the side to increase efficiency.

Wet Weather Operation

Electric mowers must not be used in the rain, there may be a short circuit. When the precipitation stops, you need to wait for the grass to dry.

But not all gasoline mowers are protected from moisture, so some manufacturers prohibit the operation of mowers in the rain.

Principle of operation

If we consider the principle of the trimmer, then it is similar to a hand scythe. The difference is that it is equipped with a motor, with its help the cutting element is rotated.

Manufacturing companies produce the following mower models:

  • On which a gasoline engine is installed. These garden tools have a fuel tank, this is their distinctive feature.
  • Devices with an electric motor. These tools are lighter because they have a fuel tank. But when choosing such models, you need to take into account that a power source is needed for their operation.

All electric streamers can be divided into those that run on batteries and models that are connected to the mains. Each type has its own characteristics, but they affect the power supply unit. If you do not take it into account, then the rest of the structure is similar in different devices.

If you take any trimmer model, then it consists of elements such as:

  • Motor;
  • Fuel tank (electric lawn mowers do not have one)
  • Levers with which the mower is controlled;
  • Grass cutting knife;
  • Barbell;
  • A spool with a wound line, which is used for cutting grass;
  • Protective cover;
  • Bevel gear.

The motor is placed near the mowing head and can be mounted from below or from above. The reducer is available only in those models that have a straight bar. If it is bent, then the main bearing becomes the connecting element. It consists of 2 bushings.

The choice of the cutting element depends on how hard the grass must be mowed. Most often, a fishing line is used in the work, it is called a cord. There are products of various shapes on sale, among buyers in demand are spiral and round.

The fishing line is wound on a spool, it is inserted into the spool, while the 2 ends of the wire remain free. When the mower engine starts to work, the bobbin rotates, the grass is cut with the free ends of the line.

How to use the trimmer correctly

Garden trimmers are efficient. Newbies think it’s easy to operate a lawn mower by plugging it in or refueling, but that’s not entirely true.

The efficiency of the garden tool and its service life directly depend on the operating conditions. Therefore, before using the trimmer, you need to do some preparatory work.

The lawn from which it is necessary to mow the grass is carefully examined. Glass and large stones must be removed. When flying out from under a running mower, they can injure a person. Wire is removed from the lawn, because it can wrap around a rotating element, break the mower.

After that, proceed to the installation of the cutting system. There are small power trimmers on sale that use only line. It is designed for cutting juicy and soft grass. But there are models with a capacity of more than 1 kilowatt, on which metal knives are installed. They cut sow thistle and other hard weeds, trim young shrubs.

In order to replace the cord with knives, you need to Unscrew the fastening nut, install the cutting element. Then the nut must be returned to its place, tightened with a wrench.

The operator must take care of his own safety. It is necessary to mow the grass in tight protective clothing. Special goggles are used to protect the eyes; they protect against dust, grass and flying debris. Hands are covered with gloves.

The electric trimmer is plugged into the network, and battery models are charged for several hours before use. Gasoline mower is filled with fuel.

Hold the mower so that the spool or knife is parallel to the ground. When the tool is in the correct position, turn on the motor. Turn off the mower after the grass has been cut.

Running in

Before starting operation, be sure to run in gasoline mowers. The operator turns on the engine, it should run for a while at idle speed. Necessary Make sure that the engine does NOT overheat, the load does not have to be.

When running in lawn mowers, the load is gradually increased. If you start working at high speeds, the motor will not work well, this will affect the further operation of the mower.

When you start it for the first time, you should not completely use up the temporary resource. After the engine runs at idle speed, you can proceed to treating the lawn. The mower should NOT run for more than 15 minutes, after which the motor is turned off, it should cool down.

If you need to run the trimmer, the braid is first assembled. Then do Trial runs at least 3-5 times. If the engine is running well, proceed to mowing. At first they work NOT more than 5 minutes, then the duration of work is gradually increased.

Oblique under hay

It is better to mow hay with a fishing line, and a metal disc. The grass is cut at the root, keeping its length as much as possible.

Adjusting the carburetor lawn mowers, trimmer

Increased fuel consumption and rapid formation of carbon deposits on the spark plug when used correctly. A properly prepared fuel mixture indicates the need to adjust the carburetor. Here’s how to adjust trims with carburettors with one fuel adjusting screw.

Carburetor adjustment

Before adjusting the carburetor, flush the air filter. It is recommended to rinse it after every 10 hours of operation. After that, you can start adjusting. The photo shows a PRORAB-8406 petrol trimmer carburetor for example. The numbers indicate the adjusting screws that we will use.

PRORAB-8406 petrol trimmer carburetor adjusting screws

Purpose of adjusting screws:

  • Fuel mixture adjustment screw.
  • Idling adjustment screw.
  • Maximum speed limiting screw.

Start a lawn mower and wait for it to warm up.

Fuel ratio

I read somewhere that if different mixing ratios are indicated in the lawn mowers manual and on the Oil Canister, the proportion specified in the manual should be used.

For a long time he did this. Excess oil dripped from the engine onto the gas tank and carbon deposits were constantly formed on the spark plug, since the manual indicated the proportion for the run-in engine 1:25, and on the Canister. 1:50. After switching to a ratio of 1:50, the appearance of oil drips stopped. The plug continued up, but with less intensity (the carburetor was NOT adjusted yet).

Until now, some users of gasoline tools determine the proportion of the fuel mixture by eye. If the amount of oil is lowered during the preparation of the mixture, after a while an extraneous sound may appear immediately after starting the engine, gradually disappearing during warming up, and the engine stops with a sharp jerk. Continued use of the trimmer in this mode will lead to its failure.

From personal experience

Maximum speed limitation

After adjusting the fuel mixture and low speed, check how the lawn mower engine will run at maximum speed. If necessary, limit the maximum speed to the required level using the hollow screw No. 3. Loosen the retaining nut and turn in the screw to decrease the maximum RPM or turn it back to grow. After adjustment, tighten the nut. The maximum RPM setting is necessary to protect the trimmer motor from overheating and to be able to use the start key lock to reduce right hand fatigue.

In the future, it may be necessary to adjust the trimmer carburetor. For example, if the engine starts to rev poorly when running at full load, loosen screw # 1 another quarter turn. If starting is difficult, increase idle speed. Both the weather conditions and the quality of the fuel mixture can affect the operation of lawn mowers. Here vibrations can turn the adjusting screws themselves.

Fuel supply adjustment

Start slowly tightening the fuel mixture adjustment screw until the engine does NOT start to stall or until it stalls if you do not have time to catch the moment. After that, unscrew the screw a quarter of a turn if the engine has not stalled, or half a turn if it stalled. Start the stalled engine. Check by opening the throttle as the engine picks up speed. Continue to loosen screw # 1 a quarter of a turn until the engine does NOT accelerate steadily when bumping. This will be the moment of the most economical stable operation of the engine. In the PRORAB-8406 petrol trimmer, the adjusting screws are turned clockwise, unscrewed. On the contrary, some other brands of lawn mowers may have the opposite.
