Operating Instructions
Throttle cable adjustment
During Break-in Period
Working with Shaft Extension
(special accessory)
Do not fit the shaft extension until the full
length of the auger is in the hole.
:
Check adjustment of throttle cable –
see chapter on "Adjusting the
Throttle Cable".
A factory new machine should not be run
at high revs (full throttle off load) for the
first three tank fillings. This avoids
unnecessary high loads during the
break-in period. As all moving parts
have to bed in during the break-in
period, the frictional resistances in the
engine are greater during this period.
The engine develops its maximum
power after about 5 to 15 tank fillings.
If tank has been run completely dry
and then refilled:
Starting a hole with the shaft
extension fitted increases the risk of
personal injury because the unit is
then at chest height and cannot be
kept properly under control.
:
Press the fuel pump bulb at least
fives times.
:
Now start the engine.
For the same reason the shaft
extension must be removed before
the auger is pulled out of the hole.
During Operation
After a long period of full-throttle
operation, allow engine to run for a while
at idle speed so that the heat in the
engine can be dissipated by the flow of
cooling air. This protects engine-
mounted components (ignition,
carburetor) from thermal overload.
After Finishing Work
Wait for the engine to cool down. Drain
the fuel Kraftstofftank and store the
machine in a dry place. Check the
tightness of all accessible screws and
nuts (not adjusting screws) at regular
regulars and retighten as necessary.
