To optimise the life and reliability of your brushcutter or trimmer, it's important to service it regularly. Here are a few points that will help you look after your brushcutter.
Clean the outside of the machine.
Make sure the harness is not damaged.
Make sure the throttle trigger lock and the throttle function correctly from a safety point of view.
Check that the stop switch functions.
Check that the cutting head does not rotate while idling.
Clean the air filter. Replace if necessary.
Check that the guard is undamaged and not cracked. Replace the guard if it has been exposed to impact or is cracked.
Check that the blade is well centered, sharp and not cracked. An uncentered blade causes vibrations that can result in damage to the machine.
Check that the trimmer head is undamaged and not cracked. Replace the trimmer head if necessary.
Check that the locking nut is tight.

Check that all nuts and screws are tightened.

Clean the cooling fins on the flywheel.
Clean or replace the exhaust's spark arrest screen (not on exhausts with a catalytic converter).
Clean the carburettor area.

Clean the fan and the area around it.
Check the fuel filter and the fuel pipe, replace if necessary.
