Operating Instructions
During break-in period
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.
During Operation
After a long period of full throttle
operation, allow the engine to run for a
short while at idle speed so that engine
heat 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 tank. Store the machine in a dry
location. Check the tightness of all
accessible screws and nuts (not
adjusting screws) at regular intervals
and retighten if necessary.
Working with shaft extension (special
accessory)
Do not fit the shaft extension until the full
length of the auger is in the hole.
BT 131
WARNING
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 controlled
properly. For the same reason the shaft
extension must be removed before the
auger is pulled out of the hole.
Releasing a Trapped Auger
If the auger jams in the drill hole
Shut off the engine immediately.
N
Depress the momentary contact
N
stop switch – the engine stops –
release the stop switch – it springs
back to the run position.
A
Engage the auger brake by moving
N
the activating lever to position A.
Rotate the whole machine
N
counterclockwise to unwind the
auger from the ground.
After releasing the trapped auger,
N
check operation of the auger brake
– see "Auger Brake".
