What kind of lines are there

A commonly used type of line that fits on virtually all cord reel types. How to remove the spool on a pgt-800 sbm trimmer. Can’t. To ring but not the same as in a trimmer starter and spool crushed on which. This is an ordinary line for trimmer, applicable to mowing succulent grass, but to cut the dead wood with it will be much harder, and much less she can not cope with shrubs.

Usually, the cross-section that can be mowed young grass does not exceed 1,6 mm. I have on a similar trimmer how to remove the spool from the grass trimmer, and in the meantime the garden overgrown. The thicker the cord, the harder grass it can cut.

There is a line with sharpened facets in the form of a star or a square, this option is more adapted to mow dry grass just because of the presence of sharp edges, but the disadvantage is its greater wear and tear and durability is inferior to a round cord.

problems with rotation of the cutting blade

All grass trimmers have a rod with a cutting blade at the end, they come in two varieties: straight with a gearbox at the end and curved with a direct transmission to the hub. If you have a straight shaft, look at the 3 parts: coupling, shaft, gearbox. And if you have a bent rod: look at the bushing and the rod accordingly. Check for continuity of joints, check splines on shaft, gearbox or bushing. You can check the drive if the engine is working properly. Our practice shows that many people confuse motor and drive problems. If the motor is clogged or malfunctioning, it may seem like there is no transmission to the blade.

Failure of grass trimmer clutch

All gasoline trimmers have a centrifugal clutch, the essence of which is that the pads begin to separate and clutch the cup when revolutions are added. The easiest way to check the clutch is to unscrew the rod from the motor, usually 4 bolts. If the pads are worn out the clutch needs to be replaced, you hear a metallic squeal. If your trimmer is equipped with a clutch and the line is constantly rotating, then the spring is stretched.

Drive shaft and boom malfunctions

The main things to look at are: the splines on the shaft, the connection between the gearbox and the clutch cup. Also, very often users do not properly insert the boom in the connection, on trimmers with collapsible boom. Be sure to check the integrity of the shaft. Plastic bushings are broken if mowing is vibrating. Vibration is very bad for the vascular system. In order to avoid the bushings melting, they need to be lubricated and the mower needs to rest.

Gearbox breakage of a grasshopper

Gearbox is an angular transmission of rotation from boom to line for trimmer or knife, consists of a worm pair, housing and bearings. Accordingly two popular problems: souring of bearings and subsequent crumbling, or wear of the worm gear. Causes of failure. The lack of lubrication and the stress caused by, for example, mowing with a knife and hitting an obstacle deforms the gears. The shrubbery is also a hard material. Using a knife shortens the service life of the gearbox.

The chain saw likes cleanliness. You have to watch the air filter and fuel cleanliness. It is better to leave gasoline for 2 days and pass it through a simple filter. a piece of baize cloth.

Check the electrics as follows:

Unscrew the plug, check the electrode gap. We set the correct electrode gap, it is possible to do it “the old man’s way”. We take a razor blade, break it in half and put the home-made probe between the electrodes. If the blades are tight, then the gap is perfect.

Put the cap of the high-voltage wire on the spark plug and lean the spark plug against the metal surface of the engine. Yank the starter a few times. If the spark is well struck to one point, the gap is set correctly. If not. the spark is weak or “wandering”, you need to re-adjust the gap between the electrodes.

There could also be a punctured ignition coil in the electrical system. In this case, the lawnmower does not start or starts and works intermittently, and then stops, or on the “hot” does not start at all.

Check the serviceability of the coil can be checked in the same way as when checking the spark: unscrew the spark plug, lean it against the body of the grass trimmer. If there is no spark when the starter is jerked or if it appears intermittently. you need to change the spool.

Taking care of your lawnmower’s cutting units

The saw’s cutting attachments blunt or wear out over time. Working with the cutting attachment becomes more strenuous, the workload increases, and the quality of the mowing becomes worse. Iron saw blades are sharpened, plastic ones are replaced.

If the cutting attachment is a trimmer line, it wears out evenly and a new material is put into the reel. The mechanism of the line saw consists in the gradual unrolling of the spool by the centrifugal force. When in contact with grass, the line for the trimmer rubs down, from the spool is fed evenly. A special winding is needed if you set the goal of two cutting elements coming out at once without tangling with each other.

The illustration shows how to correctly wind the trimmer line onto the lawnmower reel. Before winding the newest line for the trimmer you need:

  • To change the line on a power trimmer, see the video;
  • remove pieces of the old line from the reel;
  • measure 5 meters of new string and fold it in half;
  • in the spool the guides under 3.5 ends, hook the middle part behind the notch and wind in the direction of the arrows for each half of the string;
  • the remaining 20 cm through the special notches on the opposite ends of the spool;
  • install the spring and washers, bring the ends of the line outside, close the reel with the lid.

To be able to better learn how to change the line for the trimmer on the gasoline mower, watch the video.
