BEFORE USE
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. Check to ensure that all parts of your kit are included
(see illustration and parts list).
4. Carefully remove the dust caps and plugs from hose
coupler and ram coupler.
5. Connect hose coupler to ram coupler, ensure that
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 (on reservoir body, near the back). This will
release air trapped within the reservoir. Re-tighten
the oil filler screw.
8. If using with air actuated units, an air source of at
least 7.8 CFM @ 110 psi is required.
GENERAL SAFETY INFORMATION
1. Ensure that attachments are fully engaged before
applying load.
2. Ensure that load is centrally applied to attachment or
ram saddle. Do not load off center.
3. Always monitor the force applied to workpiece by
using a load cell and indicator or you may monitor
pressure developed in the ram by using an inline
pressure gauge, then calculate the applied force
using the formula:
F = P x A, where F = lb force, P = pressure in psi,
and A = effective ram area in in
Ram Area of Model 4M04T is: 0.998 in
Ram Area of Model 4M10T is: 2.411 in
Refer to Load-Pressure correlation chart on page 11.
If bowing or bending of ram or any attachment occurs
during use, "STOP", release pressure immediately
and reconsider application. Application may not
be compatible with product, a ram kit with a higher
capacity may be needed.

OPERATION
ALWAYS monitor pressure, load or position
!
using suitable equipment. Pressure may be
monitored by means of an optional manifold and
gauge. Load may be monitored by means of a load
cell and digital indicator.
Note: Any attachment that is not loaded centrally,
as through the centerline of the ram, is considered
to be "offset". When extension tubes and/or offset
attachments are used, the rated capacity is always
reduced by 50% for each tube or offset attachment
connected.
1. Pump may be used in horizontal and vertical position
as illustrated on figure 2 below.
Figure 2 - Horizontal and Vertical position
2. Locate and close release valve by turning it
clockwise until firmly closed. (Do not over tighten)
3. Operate by pumping handle. This will send fluid
from the pump reservoir into the high pressure hose
assembly and into the ram assembly.
4. Continue pumping until ram reaches desired
position.
NEVER operate pump with release valve
!
closed and disconnected from application. If
operated in this condition, the hose and connections
become pressurized. This increases burst hazard.
Damage may occur to pump and its components.
5. To Release Pressure on work piece: Slowly, carefully
turn the release valve counter-clockwise until ram
retracts to desired position. Never turn release valve
more than 1/2 full turn. The ram return system is
spring loaded and the release valve system is
metered, allowing controlled retraction of the ram.
