OPERATING INSTRUCTION MANUAL
TPA-A SERIES | AIR DRIVEN TORQUE WRENCH PUMPS
Hi-Force TPA series Air Driven Torque Wrench Pumps are premium pumps designed for use with Hi-Force
Hydraulic Torque Wrenches. TPA Pumps can be used to power up to 4 torque wrenches simultaneously
(all operating at the same pressure). Output pressure is fully adjustable and can be set to any value up to
a maximum working pressure of 700 bar (10,000 psi). This manual applies to the Hi-Force TPA series
Analogue Air Driven Torque Wrench Pumps Only. It contains the latest product information available at the
time of publication and approval. For information relating to the servicing of an Air Driven Torque Wrench
Pump, see the servicing instructions, which are available on the Hi-Force website. Hi-Force reserves the
right to make changes to this document at any time without notice.

Page 3: Inspection Upon Receipt
If in doubt on the correct use of any Hi-Force equipment, contact your nearest Hi-Force office or distributor. Only qualified personnel should be allowed to operate hydraulic equipment. If an operator has not been trained on high-pressure hydraulic equipment and its safe usage, consult your local Hi-Force sales office or distributor who can offer training courses for operators. - Page 4 NEVER attempt to solve, or clean-up leaks in the system while the system is pressurised. Immediately replace any worn or damaged parts using genuine Hi-Force parts only. DO NOT use any hydraulic equipment if you are under the influence of alcohol, drugs or medication.
- Page 5 NEVER exceed the maximum rated pressure of any hydraulic equipment. Hi-Force manufactures its TPA hydraulic pumps to operate at a maximum working pressure of 700 bar (10,000 psi). DO NOT connect hydraulic torque equipment with a lower pressure capacity rating to any Hi-Force pump of this model series.

Operating Instruction Manual: Serial Numbers: OM-TPA-A-01 5.0 Installation / Setup 5.1 Before First Use / Preparation 1. Immediately after unpacking, examine the unit for signs of transit damage and if found contact the shipping company. 2. Establish the oil level in the oil reservoir (1) using the oil level gauge (7). Depending on the shipping method used, the reservoir may either be supplied full or empty. - Page 11 Make sure both coupler halves are clean before connecting. If you are NOT using a Hi-Force Torque Wrench with the pump, or if the wrench or hoses have been modified, make sure that the wrench is connected correctly so that the male high-pressure advance coupler (9) is connected to the advance port on the tool.

- Page 13 OM-TPA-A-01 5.4 Connection of Additional Torque Wrenches Hi-Force TPA-A Pumps are equipped with additional ports allowing for up to 4 Torque wrenches to be driven simultaneously (all operating at the same pressure). This feature can be useful for even tightening of large joints. However, it must be noted that multiple torque wrenches will operate slower than a single torque wrench would, so this is not necessarily a time-saving method.

Page 18: Operation
OM-TPA-A-01 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. - Page 19 Operating Instruction Manual: Serial Numbers: OM-TPA-A-01 6.2. Setting the Pressure (Torque) Before setting the pump pressure it is necessary to determine what pump pressure will result in the torque value required. Use the tool-specific pressure-torque conversion chart provided with the torque wrench to determine the pump pressure that corresponds to the required torque value.
- Page 20 All operating functions of the pump are performed via the 2 buttons on the control pendant (14). (See figure 6.2) Hi-force recommends that operation of the pump/wrench combination be a minimum 2 person job, one to operate the pump and one to operate the wrench. An additional operator will be required for each addition wrench connected to the pump.
