Brushcutter & Trimmer
Maintenance Routines

To optimize 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 bring order to your machine maintenance.

• 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 the blade's transport guard is intact and that it can be secured correctly.
• Check that all nuts and screws are tightened.

• Check the starter, the starter cord and the return spring.
• Make sure that the vibration-damping elements are not damaged.
• Clean the outside of the spark plug. Remove and check the electrode gap. Adjust the gap to 0.5 mm (0.020") or change the spark plug.
• Clean the cooling fins on the flywheel.
• Clean or replace the muffler’s spark arrest screen (not on mufflers with a catalytic converter).
• Clean the carburetor area.
• Clean the cooling fins on the cylinder and check that the air intake in the starter unit is not blocked.
• Check that the angle gear is 3/4 filled with grease. Fill if necessary using special grease.

• Clean the fuel tank.
• Clean the carburetor and the area surrounding it.
• Clean the fan and the area around it.
• Check the fuel filter and the fuel pipe, replace if necessary.
• Check all cables and connections.
• Check the clutch, clutch springs and the clutch drum with regard to wear. Replace if necessary.
