THEORY
The MA dock leveler uses a blower motor and one-button operation for ease of use.
The dock leveler can be operated remotely using the RAISE button (O) on the control panel . This activates an electric blower motor (M). The blower forces air into the air bag (J), causing the platform to rise. Releasing the RAISE button allows the platform to lower.
When the platform rises to the point where there is
2 — 3 in. (51 — 76. mm) from 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.
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.

To lower the platform, release the Raise button (O).
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 on lip keepers (cross-traffic position).
-- Leveler went to the below-dock position, lip folds automatically, leveler rests on the safety legs
(below dock position).
-- Leveler went to the below dock position with operator holding the safety leg retract cable
