INSTALLATION
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 do this may result in
serious personal injury or death.
Two people are required to engage the maintenance
prop: one person to operate the lifting device, the
other person to engage the maintenance prop.
12. With the leveler square in the pit and flush with the
surrounding dock, remove the banding on the lip
of the leveler.
13. Connect the blower motor to the temporary power
supply.
14. Slowly raise the platform. Check for binding as
platform is being raised.
15. If binding occurs, lower the platform. Reposition
leveler and/or add or remove shims as necessary.
Slowly raise platform again. If platform still binds,
contact Poweramp Technical Services for further
instructions.
16. All AP models - Once leveler is flush, square and
does not bind:
a. Install shims under maintenance prop (C)
where prop attaches to leveler frame. Make
sure prop is solidly shimmed.
b. Using the leveler’s blower motor, raise the
dock to the fully open position.
c. Raise maintenance prop to the service
(upright) position and lock prop in this position
using an OSHA approved locking device.
17. Disconnect power supply from motor.
18. Remove air bag and pallet support from the
leveler by disconnecting air bag positioning rods
from hooks on the underside of platform.(figure
1) and removing the band clamp from the motor
coupler. (figure 2)
19. Remove or protect the blower motor from weld
sparks and splatter.
20. With the rear hinge frame angle (F) tight
against the rear pit curb angle and flush
with the 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.
