REMOVAL FROM STORAGE
Check the machine is as described in the PRE-OPERATION chapter of
this manual. If the fuel was drained during storage preparation, fill the
tank with fresh petrol. If you keep a container of petrol for refuelling be
sure that it contains only fresh petrol.
If the cylinder was coated with oil during storage preparation, the
engine may smoke briefly at start-up. This is normal.
FUEL
Petrol will oxidise and deteriorate in storage. Old petrol will cause hard
starting and it leaves deposits that clog the fuel system. If the petrol in
your engine deteriorates during storage you may need to have the
carburettor and other fuel system components serviced or replaced.
The length of time that petrol can be left in your fuel tank and carburettor
without causing functional problems will vary with such factors as fuel
blend, your storage temperatures and whether the fuel tank is partially or
completely filled. The air in a partially filled fuel tank promotes fuel
deterioration. Very warm storage/temperature accelerate fuel
deterioration. Fuel deterioration problems may occur within a few
months or even less if the petrol was not fresh when you filled the fuel
tank.
DRAINING THE FUEL TANK AND CARBURETTOR
1. Place an approved petrol container below the carburettor and use a
funnel to avoid spilling fuel.
2. Remove the carburettor drain bolt and move the fuel valve lever to
the ON position.
WARNING -
Petrol is highly flammable and explosive. You can be
burned or seriously injured when handling fuel.
•
Keep heat, sparks and flame away.
•
Handle fuel only outdoors.
•
Wipe up spills immediately.
3. After all the fuel has drained into the container reinstall the drain
bolt and tighten it securely.
ENGINE OIL & FUEL MIX RATIO
•
This machine requires 2-stroke engine oil.
•
Mix 2-stroke engine oil with petrol at a 40:1 Ratio (Petrol:Oil).
•
Use the fuel mix bottle provided to measure the ratio correctly.
•
Not enough oil (lean mix) will score the piston.
•
Too much oil (rich mix) will cause the engine to smoke.
•
Using no 2-stroke oil will result in engine failure.
•
Be careful when handling fuel or oil as prolonged exposure can be
harmful.

CHECK THE AIR FILTER
Obstruction of the air filter will cause engine problems. Check and clean
it regularly. If damaged, replace it with a new filter. The engine will not
work properly without the filter installed and it can damage the engine
permanently.
CHECK THE FUEL FILTER
The fuel tank has a filter. This part is located at the end of the fuel hose
and can be removed using a wire in the shape of a crochet hook, or
another similar method. Periodically check the fuel filter. Do not allow
dust to enter the fuel tank. Obstruction of the filter makes starting more
difficult or produces engine malfunctions. When the fuel filter is dirty,
replace it. If necessary you can clean the interior of the fuel filter with
fuel.
CHECK THE SPARK PLUG
Frequently, starting or ignition problems are caused by a dirty spark
plug. Clean the spark plug and check that the spacing of the electrodes
are spaced correct (0.6 - 0.7 mm).
CHECK THE COOLING FINS
The fins of the engine case are responsible for cooling off the cylinder
through contact with the air. The fins should always be clean.
Dirty/clogged fins can overheat the engine, which it turn may cause
seizure. Regularly check and clean the fins.
