OPERATION
Pump Operation:
1. Check all system fittings and connections to be sure they are tight and leak free.
2. Check oil level in reservoir. Oil level should be 1” to 2” from the top of the reservoir plate.
3. Be sure that the pump is “OFF”
4. Be sure the electrical connection is grounded. Check that your power agrees with the motor nameplate.
Plug power cord into outlet.
5. Press “ON” on the pump switch to turn power on. Pressing the “ON” activates the electrical circuit,
but does not turn the motor on. The pump motor is activated by the pendant switch.
6. Pendants supplied with the pumps have a momentary switch. Press momentary switch for
“ADVANCE”. Release “ADVANCE” and torque wrench piston will retract.
NOTE:
The electrical motor stays running after pump has stopped. Within 15 seconds of your
last command from the pendant, motor will turn off, preventing heat buildup.
Air removal:
When the wrench is first connected to the pump, To ensure smooth and safe operation, remove air
by cycling wrench several times without load. Cycle unit wrench advances and retracts without
hesitation.
Pressure torque setting:
!! WARNING !!
Make these adjustments BEFORE putting torque wrench on nut or bolt head.
The pump pressure setting may be above the pressure needed to provide the
required torque for your application. Exceeding required torque will cause
equipment damage and may lead to serious personal injury.
1. See torque wrench instructions for amount of pressure required to produce desired torque.
2. Loosen lock nut and back out relief valve to prevent unintended pressure build-up.
3. Turn pump on. Press and hold the “ADVANCE” switch, and read pressure gauge.
4. While holding the switch, turn relief valve in (clockwise) to increase pressure or out (counter-clokwise)
to decrease maximum pressure. Repeat until correct pressure is obtained.
5. Tighten lock nut on the relief valve to maintain setting.
6. Run pump several times to test this setting.
