25. Remove the lifting brackets from the platform side
joists.
26. Disengage the platform maintenance prop.
27. Slowly walk out onto the platform to lower the
platform until it is at the cross-traffic (stored)
position.
28. Check operation of dock leveler by cycling the
leveler at least four times.
• When the platform is at full height, lip will be fully
extended.
• Lip will begin to drop after full height is reached,
taking approximately 12 seconds to fully fold.
29. Check below-dock position by walking platform
down before lip folds completely.
• Lip will be over lip keepers.
• Platform safety legs will be resting on frame.
30. Check full below-dock position by walking the
platform down. Pull and hold safety leg chain (A)
before lip folds completely.
31. If the lip does not extend fully or lip folds too quickly,
see appropriate symptom in the Troubleshooting
section.
32. Install the dock bumpers as required.
21. Pull the release ring to raise platform. Engage
the platform maintenance prop (B) in the service
(upright) position and lock the maintenance prop
at this position using an OSHA approved locking
device (D). Engage lip maintenance prop.
22. Install shims under lift arm at locations (C) using
the pyramid shimming method. The lift arm pivot
must be solidly shimmed the entire length of the lift
arm pivot. Make sure the lift arm pivot is level from
side-to-side.
23. Finish weld all shims using a fillet weld.
• Weld all shims within each shim stack to each
other, then weld the shim stack to the leveler frame.
• Weld the front leveler frame shim stacks to the front
pit curb steel if not done previously.
24. When all welding has been completed, remove all
slag then paint all the welds and shims.
Make sure the platform is properly supported in the
raised position before entering the pit to finish weld
the shims. Failure to do this may result in serious
personal injury or death.
