Draining the fuel
Warning!
Fire and burn hazard. Draining fuel may ignite if it comes into contact with hot
engine parts or the exhaust system. Hot fuel may cause burns.
• Always wear protective equipment and safety glasses when working
with fuel.
• Never bleed the fuel system if the engine is hot.
Environment!
Use a suitable container to collect the fuel as it drains and dispose of it in an environmen-
tally friendly manner!
Filler inlet A (Fig. 103) for the fuel tank is located in the valve compartment, on the left in
driving direction.
Proceed as follows:
☞ Open filler inlet A
☞ Pump out the fuel with a suitable pump
➥ Collect the fuel in a suitable container
Stationary fuel pumps
General
Only refuel from stationary fuel pumps. Fuel from barrels or cans is usually dirty.
Even the smallest particles of dirt may cause
• Increased engine wear
• Malfunctions in the fuel system and
• Reduced effectiveness of the fuel filters
Refueling from barrels
If refueling from barrels cannot be avoided, note the following points (see fig. 114):
• Barrels must neither be rolled nor tilted before refueling
• Protect the suction pipe opening of the barrel pump with a fine-mesh screen
• Immerse the suction pipe into the barrel until there is 15 cm (6") of clearance from the
end of the pipe to the bottom of the barrel.
• Only fill the tank using refueling aids (funnels or filler pipes) with integral microfilter
• Keep all refueling containers clean at all times
