NSTALLATION
29) Lubricate the arm pin or carriage arm pin
hole with “anti-seize” and install the arms.
Insure that the arm restraint gears engage
and disengage properly. Arm restraints
should disengage when lift is fully lowered. If
any binding occurs, insure that the large gear
mounted to the arm has been factory
installed tight against the arm pin.
30) Ensure arm stop hardware is present and
adequately tightened so that spring lock washer
is fully compressed for each arm. Check arm
stop engagement by fully extending each arm.
Properly installed arm stop hardware will prevent
arm from becoming over- extended and possibly
disassembled.
Loose or missing arm stop
hardware may result in personal
injury and/or property damage.
