PREPARING THE PUMP FOR FIRST USE

1. Immediately after unpacking, examine

the pump for signs of transit damage and

if found contact the shipping company.

2. Establish the oil level in the oil reservoir

using the level gauge on the end of the

tank. Depending on the shipping method

used, the reservoir may either be supplied

full or empty. If the reservoir is empty it

must be correctly filled before use.

Remove the temporary transit plate which

is fitted in the position of the filler breather

cap (5) by undoing the 3 screws. Fit the

filler breather cap (packed separately)

using the 3 screws which held the transit

plate.

3. To fill the reservoir: Remove the filler cap

(5) and fill the tank with clean HFO46 oil to

the upper level indicator (7).

4. Make sure that the voltage indicated on

the motor rating plate corresponds with

the available supply.

5. Remove steel or plastic hexagon

headed plugs and make hydraulic

connections to service ports (11). These

ports have a 3/8" NPT female thread and

the corresponding male connections

should be wrapped with PTFE tape or

other suitable sealant. N.B On 3 way valves

the service port is the right hand one,

when viewed as in figure 1.

6. Ensure the lever of the hydraulic

directional control valve (2) is in the

neutral position: This is fully anticlockwise

for models with 2 way valve or the central

position for models with 3 or 4 way valves.

Where valves are remotely mounted,

ensure these are adjusted such that

pressure will not build up during the

starting operation. See table on page 1.

7. Ensure switch is set to 'off' (8). Connect

motor to required power source.

8. Check the direction of the motor

rotation by turning the starter switch (8) to

the 'ON' position then to the 'off' position,

whilst doing this observe the motor fan.

The motor should run in a clockwise

direction viewed from above. If the

direction is wrong check the wiring of the

electrical connector. Running the pump

with incorrect rotation may damage the

low pressure pump unit.

OPERATION OF PUMPS WITH MANUAL

VALVES

Hi-Force does not necessarily know what

equipment this pump will power. Read

and understand the appropriate

operating instructions relating to the

equipment in use.

1. With all hydraulic connections made

and motor running, operate the

directional control valve (2) if fitted to

control the cylinders or tools in use.

For pumps with 2 way valves: Turning the

lever fully clockwise will supply oil to the

service port and advance the cylinder.

Turning the lever anticlockwise will retract

the cylinder.

For pumps with 3 way valves: Mid position

is the load hold position. Moving the lever

so that it is above the service port (anti-

clockwise) will supply oil to the port and

advance the cylinder. Moving the lever

away from the service port will connect

the service port to tank and retract the

cylinder.

For pumps with 4 way valves: Mid position

is the load hold position. Moving the lever

so that it is above either service port will

supply oil to that port and connect the

opposite port to tank.

2. The pump is fitted with an adjustable

pressure relief valve (10) to restrict the

output pressure to any desired value up to

the maximum working pressure of the

pump. To increase the relief valve setting
