INSTALLATION GUIDE
Attaching motor to linkage assembly
The motors must be attached to the linkage assemblies before continuing the
installation process.
CAUTION: HANDLE WITH CARE.
To ensure our customers receive all components with full integrity, we pack
the motors separate from their linkage assemblies. This requires that the
installer position and fasten the motor before continuing with the install.
Please follow the instructions below and handle the assembly carefully.
CAUTION: Dropping the assembly or any excessive impact MAY cause
damage to the motor.
Instructions:
1. Position the gear cover in place as shown if not already in place.
2. Seat motor into position on the three mounting bosses. This may require
an adjustment of the gear by moving the swing arms.
3. After seating into place, fasten the motor with the three motor mount
screws with 4mm Hex Head. Tighten screws to 36 in-lbs (4N-m). Do not
over torque.

POWERSTEP OPERATION The AMP Research PowerStep™ automatically deploys when any door
is opened. When both front and rear doors are closed, it retracts automatically under your vehicle.
The drive system is designed to automatically stop if resistance, blockage or icing occurs.
To reset, clearany obstruction, then simplyopenand close the doorandnormal operation will resume.
MAINTENANCE TIPS - The stepping surface and linkages should be periodically washed with mild soap
and water using a soft brush or sponge to dislodge any mud, dirt or accumulated road grime.
In severe driving conditions, pressure washing the linkages is strongly recommended.
