MAINTENANCE and STORAGE
Air Cleaner:
Every 25 hours, please remove the cleaner’s outside cover. Then clean the inside dust. When
the element is dirty, clean it in warm water and dry it before installing.
A clogged cleaner will reduce engine performance. If there is no cleaner or it is damaged or deformed,
NEVER start the machine, otherwise the engine will damage quickly.
Fuel Filter:
Every 25 hours, take the filter from the fuel tank for dust cleaning. If it is dirty, replace it. The
clogged filter will reduce the engine speed and the speed is not stable. After removing the filter, use a clip to
hold the suction pipe to prevent fiber or dust.
Spark Plug:
The spark plug is easily clogged by carbon deposits. Every 25
hours of operation, remove the spark plug and clean the electrodes with a steel
brush. The suitable clearance of the spark plug is 0.6~0.7mm.
Gear Case:
Every 20 working hours, use the grease pump to add grease to the hear case from the inlet.
Blade:
Every 1-2 hours add grease to the blade.
Mending the Blade:
1.
Start the engine, allow the blade to run at low speed, stagger the up and down
blade for 2mm and stop the engine.
2.
After fixing the unit, sharpen the cutting edges with a flat or a grinder.
3.
Start it again, stagger the blade for 2mm, then stop it.
4.
Sharpen the side blade and sharpen the top of the blade.
Muffler:
Every 50 hours, remove the muffler, clear the inner carbon deposit with a screwdriver. At the same time clean
the carbon from the exhaust port.
IMPORTANT:
Aged fuel is one of the major causes of engine starting failure. DO NOT over-tighten the tank
lid. This can damage the sealing ring.
1.
While cleaning the machine, inspect every part for damage or loose parts. If found, repair it before using
the trimmer again.
STORAGE
2.
Empty the fuel tank completely. Run the engine until it stops from the lack of fuel.
3.
Remove the spark plug and put 2-stroke oil in the engine. Pull the starting ropes 2-3 times, replace the plug
and stop it at the contraction point.
4.
Apply anti-rust oil to the metal parts such as the throttle wire. Put the cover back on the blade and keep it
indoors. Avoid putting the trimmer in damn atmospheres.
