for both the drive motor and the hydraulic pump motor.
The fuses are located on the contactor panel. Remove
and replace as required. See Figure 5 and Figure 6.
The motorized hand trucks use a single 4-amp (FU2)

for both the drive motor and the hydraulic pump motor.
The fuses are located on the contactor panel. Remove
and replace as required.
If it cannot be determined visually that a fuse has
