31) Ensure that the arm restraint gears engage
and disengage properly. Arm restraints
should disengage when lift is fully lowered. If
any binding occurs, ensure that the large
gear mounted to the arm has been factory
installed tight against the arm pin.
32) 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.
33) Extend the footpad to both extents and apply
anti-seize to the three retaining rings and
where the double screw makes contact with
the base of the footpad.
