The fuses are located in different places on the superstructure:

Information on
replacing fuses
The positions of the fuses, their designations and which functions are pro-
tected by the respective fuses are shown in the following sections.
• Switch off the ignition whenever a fuse has to be replaced.
S
Risk of damage when the ignition is switched on
Switch off the ignition whenever a fuse has to be replaced. This prevents
the new fuse from being damaged by the increased starting current imme-
diately after being installed.
S
Risk of damage by overloading
Replace blown fuses only with new fuses of the same amperage. This pre-
vent parts from being overloaded and damaged or the fuse from being
immediately damaged again.
Notify Manitowoc Crane Care if a fuse with the same amperage fails again
once the ignition is switched on.
S
Risk of fire
Never repair a blown fuse with other electrically conductive materials.
