OPERATING MANUAL & PARTS LIST FOR 520-6004 B, 520-6008 B
SETUP
This is the safety alert symbol used for the SETUP and OPERATING INSTRUCTIONS section of this manual to alert you to
potential personal injury hazards. Obey all instructions to avoid possible injury or death. IMPORTANT: Before attempting to
raise any vehicle, check vehicle service manual for recommended lifting surfaces.
PLEASE REFER TO THE EXPLODED VIEW DRAWING IN THIS MANUAL IN ORDER TO IDENTIFY PARTS.
1.
One end of the handle has a cut out that will fit over the cross pin in the release valve in the base of the device. Some devices are
equipped with an integrated lever that can be used in place of the handles. This connection enables the user to turn the release
valve in a clockwise direction until tight in preparation for pumping the device and raising the load. Slowly turning the release
valve in a counterclockwise direction will lower the load. It is not necessary to open the release valve more than two full rotations.
2.
The pump handle must be inserted in the pump piston receiver linkage in preparation for pumping the device.
3.
The ram is that part of the device which extends when the device is pumped.
4.
Sometime air gets trapped in the hydraulic system during shipping and handling. If the pump feels spongy, or there is not a full
incremental pump stroke, or the device will not raise to maximum height, follow these instructions in order to purge air from the
system:
a.
With the lift arm in its completely retracted position and the pump handle rotated all the way in a clockwise direction until it
stops, rotate the pump handle in a counterclockwise direction two full revolutions.
b.
Proceed to pump the device 15 full incremental pump strokes.
c.
Rotate the pump handle clockwise until it stops and proceed to pump the handle until the lift arm reaches maximum height.
d.
Repeat steps "A" through "C" until all air is purged from the system.
5.
Follow the operating instructions that accompanied the Balkamp shop crane.
PREVENTATIVE MAINTENANCE
This is the safety alert symbol used for the PREVENTATIVE MAINTENANCE section of this manual to alert you to potential
personal injury hazards. Obey all instructions to avoid possible injury or death.

Always store the device in a well protected area where it will not be exposed to inclement weather, corrosive vapors, abrasive
dust, or any other harmful elements. The device must be cleaned of water, snow, sand, grit, oil, grease or other foreign matter
before using.
2.
The device must be lubricated periodically in order to prevent premature wearing of parts. A general purpose grease must be
applied to the pump linkage and piston pivot point.
3.
Every device owner is responsible for keeping the device label clean and readable. Use a mild soap solution to wash external
surfaces of the device but not any moving hydraulic components.
IMPORTANT: In order to prevent seal damage and device failure, never use alcohol, hydraulic brake fluid, or transmission oil in the
device. Use NAPA Hydraulic Jack Oil #765-1541.
4.
Inspect the device before each use. Do not use the device if any component is cracked, broken, bent or shows signs of damage.
Do not use the device if it has loose or missing hardware or components, or is modified in any way. Take corrective action before
using device again.
