6 ELECTRIC MOTOR
The power is supplied by a 24V 1/3 HP electric
motor coupled with a speed reduction gearbox.
Opposite to the gearbox, the motor is equipped
with a 3/8 hexagonal socket shaft extension
permitting to move the slide-out without using
the handheld control. This is very useful when
moving the slide-out very slowly is required like
during the inner stoppers adjustment, the tilt
adjustment or the 2" inside retraction. See
section 18 for the manual override procedures.
CAUTION
When moving the slide-out with a cordless
power drill as described in the manual
override procedure, be careful as the slide-out
approaches its opened or closed position, in
order not to overload the mechanism.
6.1 MAINTENANCE
Inspect the electrical connections and their
watertightness. Check that the mounting bolts
are tight (FIGURE 18).
6.2 REPLACEMENT
1. The slide-out must be retracted.
2. Unplug the electric cable connector.

on the vehicle mounting bracket. Tighten
mounting bolts to a torque of 18 lbf-ft in a
criss-cross patern.
CAUTION
To prevent damaging threads, use your
fingers to drive the bolts into the aluminum
gearbox housing mounting holes.
6. Reinstall the jaw couplings.
