THEORY
The CA dock leveler uses Compressed Air with a lanyard or (single push button) operation for ease of use.
The dock leveler can be operated three different ways. 1)
RAISE button (N) on the control panel. This activates an electric solenoid (P). The solenoid allows compressed air into the air bellows causing the platform to rise. Releasing the RAISE button allows the platform to lower.
The lip assist spring (not shown) also helps keep the lip extended. When the lip is fully extended, the lip latch cable engages the lip latch assembly, locking the lip in the extended position. The dock leveler has reached its full height when the lip is fully extended.
2) RAISE button (N) on the control panel. Allows allows compressed air into the air bellows causing the platform to rise. Releasing the RAISE button allows the platform to lower.
3)Pull up and hold the Lanyard chain in the rear of the unit until platform and lip are fully extended. Releasing the chain allows the platform to lower.
The regulator(R) supplies 95 psi to the bellows. (J)
To lower the platform, release the lanyard (Q) or RAISE button (N).
The platform will lower until the extended lip rests on the truck bed. If the lip did not fully extend or there is no truck at the dock the platform will lower until one of the following conditions occur:
• Lip is resting in lip keepers (cross-traffic position).
• Leveler went to the below-dock position, lip folds automatically, leveler rests on the safety legs
(below dock position).
When the platform rises to with in 2-3 in. (51-76. mm) of its full raised height, the lip spring (F) and lip actuator chain (G), causes the lip linkage assembly to push the lip out and up.
• Leveler went to the below dock position with operator holding the safety leg retract cable (not shown), safety legs are retracted, lip folds automatically causing dock to rest in the full below dock position.

NOTE: Refer to illustration for left/right orientation of dock leveler.
The model/serial number decal (A) is located on the right platform joist near the front (lip) of dock leveler.
When you receive your CA-Series dock leveler, write down the dock leveler model and serial number in the form provided. This will help ensure safe keeping of the numbers in the event the model/serial number decal (A) becomes lost or damaged.
Also, write down McGuire job number, the company that installed the dock leveler, and the original owner’s name. This will all help to identify the specific dock leveler if more information is required.
When ordering, use part numbers and description to help identify the item ordered. Do not use “item” numbers. These are only for locating the position of the parts. Always give dock leveler MODEL NUMBER and/or SERIAL NUMBER.
