MAINTENANCE
Important
: Use only a good grade
hydraulic 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 ram and the potential for sudden and
immediate loss of load. We recommend
Mobil DTE 13M or equivalent.
Adding oil
1. Lower ram fully
2. Set pump unit in its normal, level
position.
3. Locate and remove oil filler screw .
4. Fill until oil is within 3/8" of the filler
hole opening
5. Reinstall oil filler screw.

OPERATION
Caution:
Never operate pump
connecting with hydraulic hoses
but without application. If operated in
this condition, the hydraulic hose and
connections become pressurized. This
increases burst hazard. Damage may
occur to pump and its components.
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.
Note:
To protect the ram, stop pumping
when ram is fully extended. Continued
pumping will pressurize the system.
4. Pump may be used in horizontal and
vertical position as illustrated below.
Figure 1 - Horizontal and Vertical Position
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.
How to bleed air from ram:
Place ram upside down, fully extend and
retract the ram 2 or 3 times.
!
To avoid crushing and related injuries:
NEVER work on, under or around a
load supported only by a ram. ALWAYS
use adequately support device.
(continued)
system life, replace the complete fluid
supply at least once per year.
1. Lower ram fully
2. Remove the oil filler screw from the
pump reservoir as above.
3. Lay the pump on its side and drain the
fluid into a suitable container.
Note:
Dispose of hydraulic fluid in
accordance with local regulations.
4. Set pump in its level upright position.
5. Fill with good quality hydraulic oil to
within 3/8" of the oil filler screw hole
opening.
6. Reinstall oil filler screw.
Lubrication
A coating of light lubricating oil to pivot
points, axles and hinges will help to prevent
rust and assure that pump assemblies
move freely.
Note:
Never use sandpaper or abrasive
material on these surfaces !
Cleaning
Periodically check the pump piston and
ram for signs of rust or corrosion. Clean as
needed and wipe with an oily clo
th.
Storage
When not in use, store with the pump piston
and ram fully retracted.
How to remove a faulty coupler
If ram does not retract, secure load by
other means. Open pump release valve
to depressurize pump and hose. To avoid
the spilling from hydraulic oil, wraps
the grasping tool with rags or similar
padding. Remove the ram from application.
Disconnect and replace coupler.
Be sure all tools and personnel are clear
before lowering load.
