3.6.1 Starting the diesel engine
VORSICHT!
Caution!
Unintentional start-up!
Hydraulic oil pressure is built up automatically!
After starting the drive motor, the hydraulic pumps immediately deliver oil.

Insert the key into the key starter switch (12) (Fig. 45) or (Fig. 46) .

Press the key in slightly and turn it clockwise to the first locking position.
The warning lights (1 + 2) light up during a short automatic check (Fig. 45) or (Fig.
46) . If no faults are detected, the lights go out after approx. 2 seconds.

If light (1) (Fig. 47) does not go out, check the fuel supply.

Actuate the starter by turning the key further clockwise.
If the motor fails to start up immediately, do not continue trying to start it for more
than 10 seconds.
After each start-up procedure, take a one-minute break. Observe cold-start infor-
mation in the motor operating instructions.

Once the motor has started, let go of the starter key immediately.

Increase the motor speed slightly using the button (11) (Fig. 45) or (Fig. 46) and
let the diesel engine warm up at a moderate speed without a load. Pay attention
to any irregularities.

Once the diesel engine has warmed up, check the nominal output (operating
speed). To do this, increase the rotational speed with the button (11) and make
sure the adjustable maximum speed does not exceed the nominal speed.

If the nominal speed (chap. 2.6) is exceeded, lower the rotational speed imme-
diately with the button (10).
• Have the engine timing checked.

If the nominal speed is not reached:
• Have the engine timing checked.

Reduce the engine speed to idle until the concrete pump is placed into opera-
tion.
