Operation

Skin injection hazard:
High pressure oil easily punctures
skin causing serious injury, gangrene,
or death. If injured, seek medical help
immediately to remove oil.
• Do not use fingers or hands to
check for leaks.
• Depressurize hydraulic system
before servicing or disconnecting
the hose.
Procedure for depressurizing the hydraulic system:
1. Disconnect the pump from the power source.
2. Rotate the release lever to AUTO RELEASE and
allow the ram to retract fully.
3. Disconnect the hose slowly to release any
trapped pressure.

975 Hydraulic Power Pump
Note: To prevent leakage, this pump was shipped with
an unvented plug installed in the reservoir fill hole. This
plug must be replaced with the attached vented plug
(6) before use. Failure to replace the unvented plug will
cause poor performance.
Note: Starting the motor without a tool attached to
the pump will cause the pump to immediately build an
internal pressure of 700 bar (10,000 psi). If this happens,
shut off the pump and turn the release valve to AUTO
RELEASE to release the hydraulic pressure.
1. Move release valve lever to the AUTO RELEASE
position.
2. Check reservoir oil level. The oil level should be
within 25 mm (1 inch) of the top of the reservoir. If oil
level is too low, see Adding Oil in the Maintenance
section for instructions.
3. Place release valve lever in desired position:
• AUTO RELEASE – ram will stop and then retract
when the hand switch or foot switch is released.
• MANUAL RELEASE – ram will stop but will not
retract when the hand switch or foot switch is
released.
4. Press the hand switch or foot switch to advance
the hydraulic ram. When finished, release the hand
switch or foot switch.
Note: If release valve lever is in the MANUAL
RELEASE position, the ram will not retract. To
retract ram, rotate the release valve lever to the
AUTO RELEASE position.
