TURNTABLE
If your lift is equipped with a rotating turntable, the following operational/ maintenance procedures apply.
A. INSPECTION
As with the basic scissor lift, inspect the unit to be sure no damage has occurred in shipment and that
the unit is complete.
1. Rotate the turntable by hand to be sure the table rotates freely without binding or unusual
sounds.
2. Inspect for loose/ damaged connections and nuts/bolts.

PNEUMATIC ROTATIONAL POSITIONING LOCK
B. INSTALLATION (IF EQUIPPED) OF PNEUMATIC POSITIONING LOCK
The initial pneumatic connections differ from a standard lift and are specified below. All other installation,
safety and use instructions should be observed. Refer to schematic Fig. 8 and Fig. 9.
1. Connect incoming air supply to inlet (A).
2. Connect supply line (B).
3. Connect control line (C) lifting.
4. Connect control line (D) lock.
Positioning Lock:
The lock is designed for holding the turntable in place; it is not designed to stop or brake a rotating load.
1. Manually rotate the turntable to the desired position.
2. With the turntable at rest, activate the lock control valve to the “on” position. This will lock the
table in place.
3. Moving the control valve to "off" will release the lock and allow the turntable to rotate.
