THEORY
INTRODUCTION
General Information
The Centra Power system eliminates individual
hydraulic pumps located on each leveler. The
Centra Power pump station will run multiable
dock levelers and or truck restraints. When
the leveler is raised or when a truck restraint
is engaged a signal is sent to the pump station
to turn on. Also a signal is sent to a valve
assembly located under the leveler. When the
valve is activated and the pump is running the
leveler will raise or the restraint will engage.
The Centra Power Pump station allows more
than one leveler or truck restraint to be run at
the same time.
Congratulations on your choice of a Poweramp
dock leveler. This manual covers the Centra Power
hydraulic system.
Designed by Poweramp to be a marvel of simplicity
and efficiency, your Centra Power hydraulic system
properly installed, will provide many years of troublefree performance with an absolute minimum of
maintenance. Its revolutionary hydraulic system
efficiently controls and operates every function. To
obtain maximum performance and longest possible
use, a simple program of preventive maintenance is
recommended.
The Centra Power System comes equipped with an
electrical control panel, which allows push button
operation of the dock leveler functions. Each dock
leveler and control panel has been factory prewired
and tested to ensure satisfactory operation.
4111-0030 — Nov.2009

INSTALLATION
Read carefully and under stand the installation manual for the leveler and or the restraint in
to be installed in conjunction with the Centra Power manual.
Read carefully and under stand the Centra Power Lay out drawing. The drawings will have
all the required information on hose charts, fluid capacity and location of the mid run and end
run valve blocks.
The Centra Power pump station is typically located in the center of the dock levelers with
even amount of doors on each side. The pump station should be mounted a minimum of 72”
off the finished floor (out of the way of damage).
The Pump Station Control Box should be mounted a minimum of 72” off the finished floor
next to the Pump Station.
Hose installation can be started at the pump station or at the furthest dock leveler. Note:
when installing hose or valve blocks always keep shipping caps on fittings until hoses are
connected to the .
Typical installation the pressure lines will have #8 JIC fittings and 1/2 dia. lines. The returns
lines if without restraints will be #8 JIC with 1/2 dia. hose. Pay close attention not to allow
lines to be swapped between pressure and return. When levelers with Power Hooks are
installed the return lines will have #10 JIC and 3/4 dia hose.
When all hoses valves and hydraulic connections are made and tight. Fill the reservoir with
oil (see page 15).
Fill the Pump Station reservoir (capacity 12 gals) to the full mark (See page). Starting from
the furthest dock from the pump station, run all the levelers and the restraints through several
cycles to purge all the air out of the system. Once all levelers have been cycled several
times have all the levers in the below dock position. Note: On Centra Power Systems were
both motor must run all the time the rotation must be checked. To check rotation run only one
motor at a time the levelers will work but run slow.

always lock all electrical disconnects in the OFF
position after raising the platform and engaging the
maintenance prop. Failure to do this may result in
serious personal injury or death.
Always stand clear of the dock leveler lip when
working in front of the dock leveler.
The maintenance prop MUST be in the service
position when working under the dock leveler.
For maximum protection, use an OSHA approved
locking device to lock the maintenance prop in
the service position. Only the person servicing
the equipment should have the key to unlock the
maintenance prop.
Unless the dock leveler is equipped with a tethered
remote, two people are required to engage the
maintenance prop: one person to operate the unit,
the other person to engage the maintenance prop.
Failure to follow these instructions may result in
serious personal injury or death.
Always post safety warnings and barricade the
work area at dock level and ground level to prevent
unauthorized use of the dock leveler before
maintenance is complete. Failure to do this may
result in serious personal injury or death.
Whenever maintenance is to be performed under
the dock leveler platform, support the platform with
maintenance prop (E). Position the maintenance
prop behind front header plate (F) while staying clear
of the lip. The lip will fold down after the platform
has rested on the maintenance prop. Lock the

NOTE: Refer to illustration for left/right orientation of
dock leveler.
The model/serial number decal (A) is located
on the right platform joist near the front (lip)
of dock leveler.
When you receive your dock leveler, write down the
dock leveler model and serial number in the form
provided. This will help ensure safe keeping of the
numbers in the event the model/serial number decal
(A) becomes lost or damaged.
Also, write down Systems, Inc.’s job number, the
company that installed the dock leveler, and the
original owner’s name. This will all help to identify the
specific dock leveler if more information is required.
When ordering, use part numbers and description
to help identify the item ordered. Do not use “item”
numbers. These are only for locating the position of
the parts. Always give dock leveler MODEL NUMBER
and/or SERIAL NUMBER.
