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 Operating Instruction Manual: Serial Numbers: OM-HTWP-ELECTRIC-01 From: BP5141 2.4 General Hydraulic System Safety Precautions Failure to observe and obey the following safety precautions could result in property damage, significant personal injury or death; When operating any hydraulic equipment, all operators should ensure that all necessary personal protective equipment (PPE) is worn, as specified by their employer.
- Page 5 NEVER exceed the maximum rated pressure of any hydraulic equipment. Hi-Force manufactures its HTWP Electric 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-HTWP-ELECTRIC-01 From: BP5141 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 (4) using the oil level gauge (5). 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 (7) is connected to the advance port on the tool.

- Page 13 5.7 Bleeding Trapped Air from the System Torque wrenches and hoses are not always completely filled with oil when new. Hi-Force HTWH hoses are supplied pre-filled with oil, but NEVER assume that there are no air pockets in a hose. Air trapped in the system will lead to erratic operation of the torque tool.
- Page 14 DO NOT TOUCH. NOTE: When longer hoses are used (greater than 5m), the above procedure may not remove all the air from the system. In these cases, contact your Hi-Force representative for advice on pre-filling hoses with hydraulic oil. ...

Page 16: Operation
From: BP5141 6.0 Operation Hi-Force HTWP Electric Torque Wrench Pumps are used to power double-acting Hydraulic Torque Wrenches. Make sure you read this manual in conjunction with the Torque Wrench’s operating instruction manual to ensure correct and safe operation of all hydraulic equipment in the system. - Page 17 Operating Instruction Manual: Serial Numbers: OM-HTWP-ELECTRIC-01 From: BP5141 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 18 From: BP5141 6.3. Pump Operation 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.
