8. With the rear angle welded in place, cut and remove the shipping bands.

nance prop in position to support platform. Be sure shims are located between
prop attachment point to the frame and pit floor before supporting platform with
maintenance prop.

WARNING
Be sure to securely
block platform in raised
position before entering
pit to weld shims. Do
not use maintenance
prop to support raised
platform until shims
have been welded
beneath maintenance
prop support plate
.
Be sure power supply
circuit is opened at main
service box or circuit
breaker box prior to
electrical installation.
Failure to disconnect
power supply could
result in equipment
damage and/or personal
injury or death.
CAUTION
Have all electrical work
performed only by
qualified electricians.
WARNING
10. Weld shims in place under front edge of dockleveler. Position shims so that
fillet welds can be used to secure shims. Weld shims in place under rear
vertical supports if not done previously.
11. With the dockleveler safely supported by the maintenance prop and the frame
shims welded in place, position shims to support the hoist cylinder trunnion.
Both sides of the hoist cylinder trunnions must be solidly shimmed for their
entire length. When positioning the shims, always check to make sure the
hoist cylinder trunnion is level from side to side as well as from front to back.
Once the required shims have been positioned, weld in place using fillet welds.
12. With the welding complete, the power cable can now be connected to the field
wires in the pit junction box.
13. After all of the electrical connection in the pit have been made, use the lifting
lugs to again lower the dockleveler off the maintenance prop. Remove lifting
chains or sling from lifting lugs.
14. Check to be sure the leveler is flush with dock floor and that the lip con tacts
both lip keepers evenly.
