OPERATING INSTRUCTIONS
After truck is spotted against bumpers the dockleveler user chocks the truck wheels on both sides.
The user now looks at the cargo area of the truck to see if there is ample room for the
dockleveler lip to go onto the trailer.
The lip will require about twelve inches (12”) beyond the bumper for the standard sixteen inch
(16”) lip.
If there is not sufficient clear distance to put the lip, the area needs to be cleared manually or
with a fork truck. Before a fork truck is driven on the dockleveler deck the user should verify the lip is in the vertical position securely behind the lip keepers. If the deck is below dock height the user brings the dockleveler up above the dock floor by releasing the deck using the pull in the rear center of the deck. Release pull as soon as deck is a few inches above floor height then walk on deck to bring it back to the level supported position.
After the lip contact area is clear the user goes to the rear of the deck and pulls the release after
verifying that no one will be hit by the raising deck and the extending lip. The deck comes up and the lip extends automatically. The user releases the pull and promptly walks on the deck which brings it down until the lip is on the truck bed. (DO NOT WALK ON LIP). Loading/ unloading may now commence.
If the dockleveler is equipped with optional safety legs they need to be retracted if the trailer is
below floor height. Retract safety legs by pulling ring at rear of leveler. Release safety legs immediately after lip comes to rest on trailer. Do not leave any cargo or equipment on the dockleveler deck at any time.
When loading/unloading is complete the dockleveler can be taken out of the truck by pulling the
recessed handle releasing the deck until the lip clears the truck. Wait for the lip to completely retract and then walk on the deck until it comes back to the floor height. Check to be sure the lip is behind the keepers. The overhead door of a trailer and/or the building may now be closed and the wheel chocks removed.
If the truck departs prior to removing the lip from the trailer the lip will fall to the down position.
The lip may or may not be in the keepers. The user must release the deck to a few inches above floor height, allow the lip to fully retract and walk on the deck to bring the lip down to rest behind the keepers. Visual inspection is necessary.

ADJUSTING INSTRUCTIONS
(Review Safety Precautions before doing any work.)
The key to long term, dependable use of your dockleveler is proper maintenance.
Prior to doing adjustments on your dockleveler you need to grease and oil the friction points plus clean all debris from leveler.
Cleaning is the first step. Remove all debris from the pit. Clean the lip hinge and the lip operating mechanism. Wipe dirt and/or material from ratchet mechanism including the ratchet and paw. Clean deck hinge.
Zerk fittings to be greased (lithium base preferred) as follows:
1. Lip hinge
2. Pillow block at ends of trunion
3. Rotating cam in center of dockleveler deck
4. If unit is equipped with safety stops grease both sides
Oil all moving parts liberally. The only exception is the ratchet bar and the locking paw which should not be oiled. Use a grafite base oil. Oiling is required every thirty (30) days. Oil hooking point at the end of the springs.
There are two primary adjustments required on your dockleveler as follows:
Lip Extending Mechanism The lip is extended by the lip cable and the lip counterbalance spring. The function sequence should be as follows: The deck comes up making the lip cable taught pulling the lip out with the assistance of the counterbalance spring. The lip is momentarily held in the extended position by the two hydraulic dampers. It is important to know how much tension to put on the lip assist spring. You want the maximum force you can get and still have the lip fall back to the vertical position. Repeat the following sequence until the lip doesn’t fall back to the vertical position. Grab the lip end and manually extend lip. Release the lip. If it falls to the vertical position tighten spring nut clockwise. When lip doesn’t come down to vertical position you have went too far and you need to back off the nut slightly.
Deck Raising Mechanism It is important to know how much counterbalance force you need to achieve proper operation. When making your counterbalancing adjustments, take up on all springs approximately the same amount. Your deck needs to come up with enough speed to provide the momentum to extend the lip as previously outlined. If the lip doesn’t extend when the deck comes up you need more counterbalancing force. Back off on counterbalance springs by turning the bolts counter clockwise.
Other causes of malfunction are as follows:
1. Platform hitting sides of pit
2. Bent ratchet bar
3. Worn ratchet or paw teeth
4. Broken activating cable
