SAE30 (Single viscosity) or 10W30
(Multiviscosity) 4 stroke oil.
5. Screw in the engine oil cap.
WARNING!
The oil will be contaminated or discoloured
during use. Please change the oil regularly.
For more information, please see clause:
MAINTENANCE
Never use 4-stroke oil intended for water-
cooled engines.
Never use oil intended for 2-stroke engines.
A poor oil quality may jeopardise function and
decrease the life time of catalytic converters.
Check the engine fuel
Only fuel the machine in well-lit areas. Avoid
fuel spillage. Never refuel the machine during
operation. Let the engine cool down for about
two minutes before refueling.
Refueling must not be carried out near naked
flames, control lamps or spark producing
electrical equipment such as electric tools,
welders or sanders.
1. Make sure the machine is turned off, by
turn the engine switch to the “off”
position.
2. Check the fuel by a visual check ,
remove the fuel cap and reviewing the
fuel level.
3. Full unleaded fuel from an approved fuel
container into the fuel tank, because of
fuel expands, please fill the tank to the
neck of tank only.
4. Turn the fuel cap clockwise to assembly
it in position.
WARNING.
•Do not refill fuel while engine is running
or hot.
•Make sure fuel is not leaking from the
rear outlet tube of fuel drain hole.
Use at least 90 octane fuel. We
recommend unleaded petrol as it leaves
fewer residues inside the motor and on the
ignition plug, and prolongs the life cycle of
the exhaust system. Never use old or dirty
petrol or oil/petrol mixtures. Avoid
contamination with dirt or water in the tank.
Occasionally ignition knocking or clanging
can be heard with high loads. This is
normal and no cause for alarm. If ignition
knocking or clanging occurs during normal
loads and with constant motor speed you
should change the petrol quality. If this
does not solve the problem contact an
authorized specialist dealer.
