4.6 Additional notes on starting at very low temperatures!
Never use starting sprays or similar - they are forbidden because they are dangerous.
Only use original Wacker crank.
If cranking, is too slow, the engine can start running in the opposite direction of
rotation.
In this case the air is drawn in through the exhaust and the exhaust gases excape
through the air filter. Risk of fire! Switch off engine and start it again.
Free the engine by turning it approximately 10 to 20 times with the
decompression lever in a central position. Then the engine is
decompressed, but not ready to start. This intermediate position is used to
turn the engine "free" when at very low temperatures. The turning
resistance becomes appreciably lower owing to the change in viscosity of
the oil film. At the same time you will hear that the nozzle of the fuel
injection system is injecting cleanly (rattling).
At very low temperatures (below -5
o
C), use the starting oil dosing device.
Note: Do not use more than 2 doses as otherwise there is a risk
of crank back-swing.
