16.2 Cleaning
Clean the machine and the working attachment from soil, dust, grass, chips, and small twigs, etc.
The use of solvents, harsh chemicals or abrasive cleaners leads to damage to the machine!
Therefore: When cleaning, use only mild detergent. The use of high pressure cleaners is not
recommended. It shortens the service life and reduces the operational integrity. (Water can get into
the gear!)
Impregnate bare surfaces of the machine against corrosion (e.g., anti-rust WD40)
16.3 Engine
Information about engine maintenance you can find in operation manual of the engine
manufacturer!
16.4 Clutch
As clutch wears out, the same lever could have a wider opening, being so uneasy to use. This means
that it is necessary to adjust the cable, setting clutch lever on its original position acting on the
adjustment device and on counter-nut.
16.5 Steering
If you have difficulty steering the unit, you will need to adjust the steering levers with the special
adjusters.
Slacken off the locknut and unscrew the adjusters to eliminate the play in the cable, which

can occur after initial use or normal wear. Be very careful not to unscrew the adjusters too
much because this can create another problem: the loss of traction.
Remember to tighten the locknut when you have finished.

16.6 Gearbox
The gearbox is pre-lubricated and sealed at the factory. Remove the plug and check, with machine
horizontal, oil reaches the two notches. If necessary, add the oil. Oil must be replaced when hot by
unscrewing filler cap and plug equipped with an oil dipstick. When oil is completely drained, replace
filler cap and fill up with new oil.
16.7 Air filter
NOTE: Dirty air filters reduce the engine power due to insufficient air flow to the carburetor. Regular
monitoring, especially in dusty atmosphere is therefore essential!
ATTENTION: Never clean the air filter elements with gasoline or flammable solvents: Warning. Fire
or explosion!
Do not run the engine without an air filter: This dust penetrates through the
carburetor and causing premature wear
16.8 Storage
If the machine is stored for longer than 30 days:
• Let the machine cool down
• Clean the machine and dry
• Empty Tank and carburetor completely, avoid fuel spillage
• Store in a dry, out of reach of children place, well packaged
