Westward Operating Instructions and Parts Manual
Preparation
1. Before using this product, read the owner's manual
completely and familiarize yourself thoroughly with the
product, its components and recognize the hazards
associated with its use.
2. Inspect before each use. Do not use if bent, broken,
leaking or damaged components are noted.
3. Ensure all parts of your kit are included (ref.
illustrations and parts list).
4. Remove dust caps and plugs from hose coupler
and ram coupler.
5. Connect hose coupler to ram coupler, ensuring
there are no fluid leaks.
6. Locate and open release valve. Close release
valve clockwise and pump handle until ram is
fully extended, then open release valve counter-
clockwise until ram has fully retracted.
7. With ram fully retracted and release valve open, place
pump in horizontal position. Open oil filler screw
(located on reservoir body). This will release air
trapped within the reservoir. Reinstall oil filler screw.
BASIC SETUP
The capacity of the body repair kit can be significantly
affected by the number of attachments used and the
type of load applied. When two or more extension
tubes are used together, be sure to position the
shorter tube furthest from the ram.
Bleeding Air from System
1. Place pump at higher elevation than hose and ram,
as shown in Figure 2.
2. Operate pump to fully extend and retract ram 2 or
3 times, the objective being to force air upstream
and back to reservoir.
3. To bleed air from pump reservoir, open air filler
screw. Re-install screw after bleeding.

General Instruction
1. Pump may be used in horizontal or vertical position
as illustrated (ref. Figure. 3).
2. Attachments must be fully engaged before applying load.
3. Ensure load is centrally applied to attachment or
ram saddle. Do not attempt off-center loading.
4. Always monitor the force applied to work piece by using
a load cell and indicator, or monitor pressure developed
in the ram by using an in-line pressure gauge, then
calculate the applied force using the formula:
F = P x A, where F = lbs force, P = pressure in psi,
and A = effective ram area in in2.
Model 3ZC68C ram area is: 0.998 in2
Model 3ZC69C ram area is: 2.411 in2
(ref. Load-Pressure Correlation chart on page 6)
5. If bowing or bending of ram or any attachment
occurs during use, STOP IMMEDIATELY, release
pressure and reconsider application. Application
may require higher capacity ram kit.
Operation
When using extension tubes and/
or offset attachments, reduce rated capacity by
50% for each tube or offset attachment connected.
See Replacement Parts section on page 4 for
identification of "offset" attachments.
APPLYING PRESSURE TO WORK PIECE:
1. Locate and close release valve by turning it
clockwise until firmly closed. (Do not over tighten)
2. Operate by pumping handle. This will send fluid
from the pump reservoir into the high pressure
hose assembly and into the ram assembly.
3. Continue pumping until ram reaches desired
position or minimum pressure situation is reached.
RELEASING PRESSURE ON WORK PIECE:
Turn the release valve counter-clockwise until ram
retracts to desired position. Never turn release valve
more than 1/2 of a full turn. The ram return system
is spring loaded and the release valve system is
metered, allowing controlled retraction of the ram.
Maintenance
NOTICE:
Use premium quality hydraulic jack oil. Avoid
mixing different types of fluid and NEVER use brake
fluid, turbine oil, transmission fluid, motor oil or glycerin.
Improper fluid can cause premature failure of the jack
and the potential for sudden and immediate loss of load.
ADDING OIL
1. With ram fully lowered, set pump unit in its normal,
level position. Locate and remove oil filler screw.
2. Fill until oil is within 3/8" of the oil filler screw hole
opening, re-install oil filler screw.
