Operating Instruction Manual: From Serial Number: OM-HEP2/3-01 BQ3323 5.0 Installation/Setup 5.1 Before First Use 1. Immediately after unpacking, examine the pump for signs of transit damage and if found contact the shipping company. 2. Remove the temporary transit fitting / plate which is fitted in the position of the oil filler breather cap (11) and fit the oil filler breather cap which is packed separately. - Page 9 Once satisfied the supply is suitable, an electrical connection can be made. NOTE: Supply voltages vary from country to country. Hi-Force pumps will operate within the normal voltage tolerance ranges, but in extreme cases where they are operated for long periods at high pressures and in low voltage conditions, the motor may overheat and shut down.
- Page 10 NOTE: When longer hoses are used (especially in the case of smaller capacity Figure 5.2 cylinders), 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.
