22. MAINTENANCE AND CLEANING
WARNING!
Always wear safety gloves when cleaning and servicing the device, switch off the engine and let
it cool down.
1. FILTER
The cleanliness of the filter must be checked every time it is used. If the filter on one side of the
carburettor is dusty, it must be cleaned. When assembling the filter, the sequence must be
observed: Filter core → filter→ filter core. If the dust is not removed, the dust will continue
entering the engine, causing piston wear or even damage to the engine.
2. TOOL CUTTING BLADE
If the slit between the cutters is more than 0.7mm, the cutter must be replaced. Otherwise dust
can enter the gear box through the slot and cause internal wear.
3. SAFETY CUT-OUT (1, F12)
WARNING!
Stop operation if the safety lock is defective.
The safety lock is a device that prevents unintentional operation of the throttle lever. You can
operate the throttle stick while pressing against the safety lock.
a. Make sure that the throttle lever cannot be operated if you do not press the safety lock.
b. Make sure that the throttle control can be operated if you touch or press it while pressing
the safety lock.
c. Make sure that the safety lock returns to its original position when you take your hand off
the safety lock.
If you find a defect after performing the above checks, contact your nearest service centre for
repair.
