FUEL FILTER
The fuel tank may be fitted with a filter, depend -

moisture with a soft cloth. The tines and fenders
can be cleaned with water using a garden hose.

Never store the unit with fuel in the tank and always
allow the unit to cool before storing. Store the unit
only in dry and well ventilated areas.
In case the unit will be stored for an extended time,
use the following storage procedure:
1. Drain all fuel from the fuel tank.
2. Start the engine and allow it to run until it
stalls. This ensures that all the fuel has been
drained from the carburetor.
3. Replace the engine oil with new.
4. Replace the gearbox oil with new.
5. Replace the air filter oil with new, if the air filter
is oil bath type.
6. Remove the spark plug and put 30 ml of
high quality motor oil into the cylinder. Pull the
starter rope slowly to distribute the oil. Rein -
stall the spark plug.
7. Thoroughly clean the unit and inspect for
any loose or damaged parts. Repair or replace
damaged parts and tighten loose screws, nuts
or bolts.
8. Lubricate all parts required with an oil damp
cloth to avoid rust built-up.
