About Arm Restraint Gears
Arm Restraint Gears get installed on each Lift Arm on the opposite end from the Lift Pad.
The purpose of the Arm Restraint Gears is to hold the Lift Arms in place laterally (once they mesh with
the Gear Stops) as the Lift Arm rises from the ground up to where the Lift Pads hit the manufacturer’s
recommended Lifting Points.
When the Lift is fully lowered, the Arm Restraint Gears are
not
meshed with the Gear Stops on the Lift
Head. This is because you need to be able to move the Lift Arms to position them correctly under the
Vehicle. When the Lift begins to rise, the Arm Restraint Gears mesh with the Gear Stops.
Important: Arm Restraint Gears do not keep the Lift Arms from moving once the weight of the
Vehicle is on the Lift Arms. Arm Restraint Gears are designed to maintain the position of
unloaded
Lift Arms up to 150 pounds of horizontal force. Put another way, Arm
Restraint Gears keep the Lift Arms from moving laterally from just above the ground,
when they mesh with the Gear Stops, until the Lift Pads start holding the weight of the
Vehicle being raised.
Arm Restraint Gears for all XPR-10 models have an R imprinted on one side and an L imprinted on the
other side. Before installing an Arm Restraint Gear, determine whether it is going to be a ‘left’ arm or a
‘right’ arm (described in Installing Lift Arms) and install the Arm Restraint Gear accordingly.
