Idle Speed Adjustment
Start the engine outdoors and allow it to warm up
to normal operating temperature.
Move the throttle lever to the slowest running
position. Then turn the throttle stop screw with a
cross head screwdriver to obtain the correct idling
speed which is 1400 rpm, +200/-150 rpm.
Preparation for Storage
If storing with petrol in the fuel tank it is important
to choose a well ventilated area to reduce the
hazard of petrol vaporisation. Avoid areas with a
naked flame, such a gas pilot light, or spark-
producing electric motors.
Petrol will oxidise and deteriorate in storage, which
can leave gum deposits and cause hard starting.
The length of time it can be left in the fuel tank
before causing problems varies depending upon
the petrol blend and storage temperature. The air
in a partially filled tank promotes fuel deterioration
and this is accelerated by high temperature. For
lengthy storage it is best to drain the fuel tank into
a suitable container by setting the fuel valve to ‘on‘
and removing the sediment cup and the drain plug
from the carburettor. Reinstall the sediment cup
and drain plug after draining.
Store the unit in a dry location and cover to protect
from dust, etc. Avoid areas of high humidity which
promotes corrosion.
Engine will not start
• Check if enough fuel in tank.
• Check if fuel tap is on.
• Check if fuel enters carburettor.
Remove drain plug at bottom of fuel bowl.
• Check that oil level is not too low.
The low oil level protection system may be
activated - refer page 5.
• Check that the engine switch is on.
• Check if spark available at spark plug.
• Remove spark plug, reconnect lead, earth plug
against engine block, turn engine switch on,
pull starter cord and see if spark jumps at plug
gap.
• If all above checks are OK and engine will still
not start contact your Silvan dealer
Generator fails to generate electricity
• Check to see if the AC breaker is in the on
Position
• If all above checks are OK and generator will
still not generate electricity contact your Silvan
dealer.
