22. Maintenance and cleaning
WARNING!
Always wear safety gloves when cleaning and servicing the equipment, switch off the Engine
and let it cool down.
1. FILTER
The cleanliness of the filter must be checked every day. If the filter on one side of the
carburettor is dusty, it must be cleaned. When assembling the filter, the order must be observed
as follows: Filter core → filter → filter core. If the dust is not removed, the dust will continue to
penetrate the Engine causing piston wear or even damage to the Engine.
2. CUTTING EDGE
If the slit between the cutting edges exceeds 0.7mm, the cutting edge must be replaced.
Otherwise the dust can penetrate through the slot into the gear box and cause internal wear.
3. SAFETY CUT-OUT (1, F12)
WARNING!
Stop operation if the safety cut-out is defective.
The safety cut-out is a device that prevents the throttle lever from
being accidentally operated. Throughout the safety cut-out, you can
operate the throttle.
a. Make sure that the throttle lever does not operate if you do not
press the safety cut-out.
b. Make sure that the throttle lever can be operated if you touch or press it while pressing the
safety cut-out.
c. Make sure that the safety cut-out returns to its original position when you remove your
hand from the safety cut-out.
If you find a defect in the above checks, contact your nearest service centre for repair.
4. ANTIVIBRATION SYSTEM
WARNING!
A deformed or damaged anti-vibration system can cause breakage, causing the Engine and/or
the cutter blade to become loose or fall off.
