7.0 SET-UP AND GENERAL OPERATION
INFORMATION
7.1 Before Start-up
1. Check the hydraulic oil level. Add oil if necessary. Refer to
Sections 11.1 through 11.3.
2. Connect hydraulic hoses to pump as described in Section
5.2.
3. Connect pump to a compatible AC power supply of the proper
voltage for the pump model. Input power specifications are
listed on the pump data plate and also in Section 2.1.
4. Remove air from system before placing pump into operation.
Refer to instructions in Section 7.3.
5. Check all hydraulic hoses, couplers and fittings to be sure
they are tight and leak free.
7.2 Pump Operating Positions
During operation, the pump can be positioned in the normal
horizontal position or vertically on its back cover as shown in
Figure 5.
If needed, the pump can be tilted rearward on an angle, provided
that it is adequately supported so that it does not slide, tip over
or drop.
OK OK

Figure 5, Allowable Pump Operating Positions
To prevent oil leakage and/or damage to pump:
• Never operate the pump while it is positioned on its right or left
sides, or in the inverted (upside-down) position.
• Never operate the pump in a tilted forward position. Oil leakage
and/or damage to pump may result.
See Figure 6.

7.3 Air Removal
When the torque wrench is connected for the first time, air may
be trapped in the wrench and hoses. To ensure smooth, safe
operation, run the torque wrench through several complete
advance-retract cycles before placing the pump into service.
Do this with no load on the torque wrench and with the pump
positioned higher than the torque wrench.
When the torque wrench advances and retracts smoothly and
without hesitation, the air has been vented from the system.
7.4 Operating Precautions
WARNING
Failure to observe the following precautions and instructions
may result in death or serious personal injury.
• Be sure the nut threads properly engage with the threads of
the bolt, and that cross-threading has not occurred.
• Avoid making sudden start-stop movements (“shock loading”).
Failure to observe these precautions may cause a catastrophic
failure of the wrench to occur, and wrench components under
high tension could become dangerous projectiles.
• If the torque wrench stalls at any time, press any pendant
button to stop auto-cycle operation or release the green
pendant button if using manual mode.
• Continuously monitor the torque wrench and fastener during
pump operation. Stop torquing procedures immediately if any
problems occurs.
• Refer to the manufacturer's manuals provided with the torque
wrench for wrench operation instructions, maintenance
procedures and safety precautions.
