Lamp test After the ignition has been switched on, a lamp test is performed.
• Check that the lamps (1) light up briefly, 
if they are present. If the specified time is 
insufficient, switch on the ignition again.
• If necessary, engage the parking brake 
and check that the lamp (2) lights up 
continuously.
• Check that the lamps (1) go on for approx. 
2 seconds after switching on the ignition:
If one or more lamps do not light up, refer to 
Manitowoc Crane Care.
If you could not check all the lamps in the 
specified time, you can conduct the lamp test 
again as follows.

Risk of accidents due to faulty lamps!
The lamps that are used to provide warnings and information during oper-
ation light up for control purposes whenever the ignition is switched on. 
Always perform the following lamp tests and immediately replace faulty 
lamps or have them replaced!
In this way, you will avoid accidents and damage that occur when malfunc-
tions are not identified in time.
