INSTALLATION
• 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.
24. When all welding has been completed, 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.
* For left/right orientation of dock leveler, see inside back cover of
this manual.

Stacking Methods
21. All model levelers: Install shims at locations (B,
p.11) using the pyramid or stepped shimming
method. Make sure the platform is level from side-
to-side as well as from front-to-back and flush with
dock floor.
22. Weld front of dock leveler frame (B) to shims
located under the keepers, then weld the shims to
the front pit curb steel.
23. Finish weld all shims using a fillet weld.
NOTE: The illustration on page 13 shows a typical
weld pattern. The weld pattern will vary slightly
depending on size of dock leveler.
IMPORTANT
DO NOT weld continuously along the full length of
the rear hinge frame angle. This can put unnecessary
stress on the leveler components, causing the
leveler to malfunction and shorten the life span of
the affected components.
IMPORTANT
DO NOT connect the dock leveler electrical wiring
and ground connections until all welding has been
completed.
DO NOT ground welding equipment to any hydraulic
or electrical components of the dock leveler. Always
ground welding equipment to the dock leveler frame,
NEVER to the platform.
Failure to follow these instructions may damage the
motor, wiring, and/or control panel.
DO NOT grind or weld if hydraulic fluid or other
flammable liquid is present on the surface to be
ground or welded.
DO NOT grind or weld if uncontained hydraulic fluid
or other flammable liquid is present. Stray sparks
can ignite spills or leaks near the work area. Always
clean up the oil leaks and spills before proceeding
with grinding or welding.
Always keep a fire extinguisher of the proper type
nearby when grinding or welding.
Failure to follow these instructions may result in
serious personal injury or death.
