6.0 Operation
Hi-Force TPA-A Torque Wrench Pumps are used to power double-acting Hydraulic Torque Wrenches.
Make sure you read this manual in conjunction with the Torque Wrenches operating instruction manual to
ensure correct and safe operation of all hydraulic equipment in the system.
Before applying pressure to the system make sure you observe the following points
You are aware of the correct operation of the Torque Wrench/s.
You are aware of the maximum working pressure of the Torque Wrench/s.
You are aware of the required working pressure/s that must be applied to the Torque Wrench/s.
You have read and fully understood the torquing sequence and procedure.
You have performed the relevant risk assessment/s and have a method statement (safe system of
work) for all operators to follow.
With the air motor still running the retract hose/s still contains 80 - 90 bar pressure.
DO NOT TOUCH.
6.1. Preparing the Pump for Operation
1. Connect the torque wrench/s to the pump as per section 5.3.
2. Turn the pressure relief valve (13) fully anti-clockwise (fully open position).
3. Connect the Pump to the air sup
ply using an appropriate 3/8” BSP airline fitting.
4.
Turn the air supply ‘ON’.
When the air supply is first turned on, it is possible for the pump to start
unexpectedly. If this happens, press the ‘Stop’ button on the control pendant (14)
to stop the motor until ready to proceed.
5. While monitoring the pressure on the air pressure gauge (16), use the air regulator knob (19) to
adjust the air pressure as high as the supply will allow, up to a maximum of 7.0 bar (100 psi). Make
sure that the supplied air pressure is not too high or too low.
NOTE:
The regulator knob (19) must be pulled ‘UP’ to unlock it before being turned. Once adjusted
to the desired pressure, it should be pushed back ‘DOWN’ to lock it.
6. If necessary, bleed trapped air from the system as per section 5.10.
7. Perform system leak & function tests as per section 5.11.
