MAINTENANCE AND SERVICE
Make sure the tool stands stable and not likely to tip over during maintenance and service. Re-
place damaged and worn parts immediately to reduce the risk of injury. Perform maintenance,
servicing and inspections as recommended. Use only parts with equivalent performance to
reduce the risk of damage and failure.
• Regularly check the condition of the machine to prevent breakdowns. If cracks, twists,
bends, gaps or fatigue is discovered, stop the operation and rectify the faults
• Replace worn parts. Tighten all screws and nuts after a few hours of operation, and after
that every day when using with the machine.
• Always check all bolts and nuts are tightened after maintenance and service. Always test
the machine before work is started.
• Lubricate all lubrication points regularly. Lubrication points are to be lubricated every 20
hours.
WINTER STORAGE
At the end of the season, the machine should be readied for storage (or if it will not be in use
for longer than 30 days). Fuel allowed to stand for long periods of time (30 days or more) can
leave sticky residues that can plug the carburetor and disrupt engine function. Fuel stabilizers
are an acceptable option as regards sticky residues during storage. If alkylate gasoline (As-
pen) is used, stabilizers are unnecessary because this fuel is stable. However, you should avoid
switching between regular and alkylate gasoline as sensitive rubber components can harden.
Add stabilizer to the fuel in the tank or in the storage container. Always use the mixing ratios
specified by the manufacturer of the stabilizer. Run the engine for at least 10 minutes after add
in the stabilizer so that it reaches the carburetor. DO NOT empty the fuel
tank and the carburetor if you have added stabilizer.
WARNING!
NEVER store an engine with fuel in the tank indoors or in poorly ventilated spaces where fuel
vapor can come in contact with open flame, sparks or a pilot light such as in a boiler, hot water
tank, clothing drier, etc. handle the fuel with caution. It is very flammable and careless use
can cause serious damage to person and property. Drain the fuel into an approved container
outdoors and far away from open flame. NEVER use gasoline for cleaning. Use a de-greaser
and warm water instead.
SERVICE
When ordering spare parts, please specify the purchase year, model, type, and serial number.
Always use genuine Parts. An annual check-up at an authorized service workshop is a good
way to ensure that your machine performs its best the following season.
1. the paint to prevent rust.
2. Inspect the machine for worn or damaged parts and tighten any nuts or screws that may
have become loose.
