Operation
2. Fuel Level
Stop the engine before filling the fuel tank.
Remove the fuel filler cap and fill the tank with
standard grade, unleaded petrol to the bottom of
the filler neck. To avoid spillage, do not fill the neck
of the tank. The capacity is 3.6 litres.
3. Air Cleaner
Unscrew the wing nut, remove the air cleaner
cover and inspect the filter element. Clean or
replace a dirty filter element and always replace a
damaged element – see Maintenance section.
S
tarting the Engine
Turn the ignition switch on. Slide the fuel valve
lever to the “on” position and close the choke lever.
Do not use the choke if the engine is warm or the
air temperature is high. Open the throttle slightly by
moving the lever towards the fast running position.
Pull the starter grip gently until resistance is felt,
then pull it briskly and the engine should start.
Return the starter grip gently, do not allow it to
snap back or the starter may be damaged. If the
engine does not start repeat the process.
Open the choke fully when the engine is warm and
running smoothly.
Pumping Operation
Set the throttle to the full open position to obtain
maximum pump output. If necessary the flow rate
can be regulated by adjusting the throttle position.
Stopping the Engine
To stop the engine under normal circumstances,
return the throttle lever to the idle position, close
the fuel valve and turn the ignition switch off. In an
emergency the engine can be quickly stopped by
simply turning the ignition switch off.
Operation at High Altitude
Power will drop by 3.5% for every 300 meters
increase in altitude. At high altitude the carburettor
will produce an over rich mixture, which will further
decrease engine power and increase fuel
consumption. If operating constantly at high
altitude above 1,500 m (5,000 ft) your Silvan dealer
can install an alternative main jet for the
carburettor and readjust the engine idle speed.
Petrol is extremely inflammable, and
explosive under certain conditions.
Refuel in a well ventilated area with
the engine stopped. Do not allow
smoking, a naked flame or electrical sparks to
occur during refilling.
Avoid spillage and wipe up spills immediately.
Avoid contact with the skin, petrol can burn.
Keep stored petrol out of the reach of children.
