(Installing the Lift Arms)
1. Place the Lift Arms in the Lift Heads.
2. Install the Lift Head Pins into the Lift Head and
through the holes in the Lift Arm (See Fig. 14.1).
3. Install the snap ring into the groove in the Lift Head
Pin on under side of the Lift Head. (See Fig. 14.2)
4. Place each Gear Ring against the Lift Head Pin and
align the holes in the Gear Ring with the threaded holes
in the Arm Ears. Make sure that the teeth on the Gear
Ring mesh smoothly with the teeth on the gears of the Lift
Head. (See Fig. 14.3)
5. Verify the operation of the arm restraints by pulling
up on the key ring of the arm restraint pin. Pivot the arms
back and forth and test the operation of the arm restraint
pin in various positions. (See Fig. 14.4)
6. Make sure the Lift Arms do not move when a force of
approximately 100 pounds or less is applied laterally to
the fully extended arms.
