5.2 Filling the Pump with Oil
IMPORTANT:
The HPF series of hydraulic pumps use ISO46 Grade Hydraulic Oil.
•
Remove the oil filler breather cap dipstick assembly (7).
•
Fill the reservoir with clean, high quality ISO46 hydraulic oil via the filler breather until the oil level
reaches the upper-level indicator (8) or until the oil level on the dipstick (7) measures approximately
90mm from the underside of the filler breather cap (7).
•
Replace the oil filler breather cap dipstick assembly (7).
NOTE: More hydraulic oil can be added to the reservoir to assist with cooling if required, but NEVER more
than 25mm below the tank lid.
IMPORTANT:
Only add oil to the reservoir when the connected cylinder is fully retracted. Failure to do so
will result in the system containing more oil than the reservoir can hold.
5.3 Electrical Connection
Before making an electrical connection, refer to the data plate located on the motor (4) for voltage and
current requirements (also refer to section 8.2). 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.
NOTE: A common cause of pump failure is the use of long extension cables to connect the pump to the
mains supply. The pump should be situated as close as possible to the wall outlet.
5.4 Bleeding Trapped Air from the System
Cylinders, and hoses are not always completely filled with oil when new. For safe and efficient operation,
trapped air must be removed from the system. The following procedure must be carried out with the cylinder
connected to the pump, but not operating under load.
To remove air from the system, proceed as detailed below:
•
Make sure the oil filler breather cap dipstick assembly (7) is fitted.
•
Single-Acting: Using the pump, fully advance the cylinder piston and allow to return under spring
force. Repeat several times until the operation is smooth. (See section 6 for details of pump operation).
•
Double-Acting: Using the pump, fully advance and retract the cylinder piston several times until the
operation is smooth. (See section 6 for details of pump operation).
The bleeding of trapped air from a hydraulic system must only be performed by
qualified personnel who have been trained and are competent to do so.
