6.7.1 Loosening the sleeper bolts
Follow these instructions to loosen the sleeper bolts:
1. Fit the machine socket wrench over the sleeper bolt.
2. Use the direction of rotation selector to set the correct
direction of rotation for loosening (Switch position: TOP).
3. Press and hold down the actuating switch until the
sleeper bolt is loosening completely.
The machine fi rst selects the low ratio to untighten the
sleeper bolt. Then the machine automatically shifts up into
the next ratio to unscrew the sleeper bolt.
If the sleeper bolt cannot be un-
fastened, release the actuating
button immediately.
Whenever the actuating button
is held down for an extended
period without rotation of the
spindle, the electromechanical
coupling is overloaded and,
within a few seconds, it can
reach high temperatures,
causing it to get damaged.

Starting the machine
To start the machine, follow these instructions:
1. Move fuel tap
to ON.
a. To restart the engine while hot, move the choke
lever
into CLOSED position.
b. To start the engine when cold, move the choke
lever
into OPEN position.
2. Move the throttle lever from MIN setting to 1/3 MAX.
3. Move the engine switch
to ON.
4. Quickly pull through the starter handle
. If necessary,
repeat this several times.
5. Whenever the engine is started, set the desired speed
using the throttle lever
and move the choke lever
to its CLOSED position as soon as the engine has come
up to operating temperature.

Correct operation of the machine
Before tightening the bolts,
check the machine torque against
the rotational controller on the
control panel and correct if
necessary.
Incorrect setting of the torque
can cause the sleeper bolts to be
tightened incorrectly, and they
may even break off .
The trolley for the machine does
not have any brakes and must
therefore never be left by the
operator unsupervised because,
if parked on a gradient, it could
start to roll away. For this reason,
always chock the wheels suffi
-
ciently to prevent it from rolling
away.
The clockwise direction of rotation
is used to tighten. The anti-clock-
wise direction of rotation is used
to loosen.
The display of operating hours
continues to run with each oper-
ation of the machine and cannot
be reset. It is therefore advisable
to keep a log of the operating
hours status to keep track of
scheduled maintenance work.
Follow these instructions to assure correct operation of the
machine:
1. Start the engine
(see Chapter 6.6 “Starting the machine”
on page 28)
.
2. Run the machine at idle speed for 2–3 minutes until it
reaches operating temperature.
3. Set the throttle lever to MAX.
4. Set the torque for the sleeper bolts being tightened on
the rotational controller.
