Safe operating practices

Important
In general the term "unit" is used in
the following. The engine can be
installed in different units.
Risk of explosion and fire!
!
Petrol and petrol vapours are
extremely flammable and
explosive. A fire or an explosion
may result in serious burns or
fatalities. If petrol gets onto your
body or clothing, wash skin
immediately and change clothing.
- Before refuelling, switch off the
engine and leave to cool down
for at least two minutes before
opening the fuel cap.
- Fill up the tank outdoors or in
a well ventilated area only.
- Use authorised fuel containers
only.
- Never fill up a petrol can in
a vehicle, tractor or on a trailer
with plastic panelling. Always fill
a petrol can on the ground and at
some distance from the vehicle.
- If possible, take motorised units
out of the heavy goods vehicle or
the trailer and refuel on the
ground. If this is not possible, fill
up these units with a petrol can
instead of directly with the petrol
pump hose.
- Always place the tank pipe on the
edge of the filler neck on the tank
or petrol can until the refuelling is
complete. Do not use the locking
lever for continuous filling.
- Do not overfill the tank.
Fill the tank until approx. two
centimetres below the rim of the
filler neck to allow the fuel to
expand.
- Keep the fuel away from sparks,
naked flames, warning lights,
heat and ignition sources.
- Never refuel units in closed
rooms, as flammable vapours will
form.
- Do not smoke.
Operating manual for engine
- Frequently check fuel lines, tank,
fuel cap and connection parts for
cracks and leaks. If required,
replace.
- Before starting the engine,
ensure that the spark plug,
exhaust, fuel cap and air filter
have been attached.
- Do not start the engine without
installed spark plug.
- Fuel has been spilled, wait until
the fuel has evaporated before
starting the engine.
- When operating units, do not tilt
the engine or the unit to such an
extent that fuel can run out.
- Do not use the choke to stop the
engine.
- Transport units with empty tank
only.
- Keep petrol or units with full tank
away from heaters, ovens, hot
water boilers or other equipment
which feature warning lights or
other ignition sources, as these
may ignite petrol vapours.
Risk of explosion and fire!
!
Sparks are generated when the
engine is started. These sparks
may ignite flammable vapours in
the vicinity. This may result in an
explosion or fire.
- Do not start the engine near
damaged, gas-operated
equipment.
- Do not use any pressurised
starting aids, as their vapours
are flammable.
Risk of asphyxiation!
!
Engines release carbon monoxide,
an odourless and colourless toxic
gas. Inhalation of carbon monoxide
may result in dizziness, fainting or
death.
- Start and run the engine
outdoors only.
- Do not start or run the engine in
closed rooms, even if doors and
windows are open.
Risk of injury!
!
If the engine is started unintentio-
nally, this may result in serious
injuries, a fire or an electric shock.
