8) Turn crank slowly at first until catch grabs, then turn always
faster.
9) When automatic decompression lever returns to its vertical
position, highest crank turning speed must have been
reached. Engine fires up and reaches maximum rpm’s.
Starter knob returns to initial position automatically.
☛
ATTENTION! If cranking procedure is too slow, en-
gine may start up in wrong direction. Air will be sucked in
through the exhaust and the air filter turns into an exhaust.
Fire hazard! Turn off engine and start cranking procedure
again.
Pull starting crank out as soon as the engine starts run-
ning. Then set engine’s rpm’s to idle. Let engine warm up
for 7 minutes before starting with the actual compaction
job.

ATTENTION!
Use of starting aids, such as starting sprays, is forbidden (even in extremely cold temper-
atures) because they are very dangerous. Single out defective cranks (e.g. damaged
claws, missing handle tubes) and replace.
Warning:
Incorrect starting procedures, i.e. all possible and imaginable deviations from the above
mentioned, may lead to bodily injury!
Additional suggestions for starting at very low temperatures
-
Insert crank correctly, turn automatic decompression lever to first notch and turn engine “free”, i.e., while
decompressed, turn engine over 10 to 20 times with crank. By doing this, the resistance to turn of the engine
will diminish due to the change in the viscosity of the lubricating oil. Simultaneously the correct functioning
of the injection nozzle (rattling) and the jetting of the fuel may be heard.
-
Under extremely low temperature conditions (below -5
o
C), starting oil dosification device should be used.
For engines up to approx. 6 kW (8 HP) up to 2 dosages, over 6 kW (8 HP) up to 3 dosages.
☛
ATTENTION!
A higher than recommended dosage could lead to a back-swing of the crank.
