INSTALLATION
14. Remove shipping bands at this time. Allow platform
to float. Add/Remove shims as necessary to bring
platform level/flush with floor.
17. Pull and hold the release ring (located in recess at
rear of platform) until the platform is fully raised.
Check for binding as platform rises.
18. Slowly walk out onto the platform to lower the
platform. Allow the platform to lower to the cross-
traffic position. Check for binding as platform
lowers.
19. If binding occurs, reposition leveler and/or add
or remove shims as necessary. Raise and lower
platform again. If platform still binds, contact
Technical Services for further instructions.
20. Check that the leveler is flush with the dock floor
and that the platform lip contacts both lip keepers
evenly.
NOTE: The illustration on the previous page shows a
typical weld pattern. The weld pattern will vary
slightly depending on size of dock leveler.
13. With the rear hinge frame angle (F) tight against
the rear pit curb angle (G), weld the rear hinge
frame angle (F) to the rear pit curb angle (G)
using a 3/8 in. (9.5 mm) flare bevel skip weld
— each weld being 6 in. (152 mm) long.
Start at each end with a 6 in. (152 mm) long
weld. Space all the other welds out evenly leaving
approximately 6 in. (152 mm) space between
each weld.
Alternate welding locations to distribute heat.
Welding sequentially from one end to the other
may cause warping or distortion.
15. Weld front of dock leveler frame (B) to shims
located under the keepers, then weld the shims
to the front pit curb steel.
16. Disconnect lifting device and chains from the lifting
brackets.
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 could result in
death or serious injury.
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.
ALWAYS stand clear of dock leveler lip when
working in front of the dock leveler.
Failure to follow these instructions could result in
death or serious injury.
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
lifespan of the affected components.
DO NOT use the maintenance prop to support the
raised platform until the maintenance prop has
been properly shimmed and welded. The shims
must be welded to each other, the leveler frame,
and to the front pit curb steel. Failure to follow
these instructions could result in death or serious
injury.
