Installing the Swing Arm Restraints
NOTE: ARM LOCKS MUST BE INSTALLED CORRECTLY.
The Arm Locks are essential to the safe operation of the lift.
Always maintain proper function of Arm Locks.
NEVER DEFEAT OR DISABLE ARM LOCKS.
Never operate lift with malfunctioning or defective Arm Locks.
1] Locate the Arm Lock Assemblies in the hardware box.
2] Install the four (4) Arm Lock Assemblies (one (1) in each carriage bracket) as shown
(Fig. 12A).
3] Adjust each Small Gear Block up or down in the carriage bracket to fully engage the Half-Moon
Gear on the arm. Teeth of both gears should mesh when lift is raised. When lift is lowered to the
ground, gears should completely disengage to allow arms to swing freely. Be sure gear does not
rise above the bracket.
4] Adjust each Small Gear Block forward or backward in the carriage bracket to fully engage the
Half-Moon Gear on the arm. Teeth of both gears should mesh as described above. Tighten the
lock nut to secure
5] Teeth on all gears should mesh as completely as possible. Be sure all gears “bite” completely.
NOTE: Failure to mesh gears properly
can cause slipping of lock mechanism, damage to lift and significant safety issues.
