FILLING OF PUMP WITH OIL

Remove the cap (3) from the oil filler.

Stand the pump on a level surface and fill the tank via the filler breather (3) with Hi-force HFO46 oil until the oil

level is at the maximum level as shown on the level gauge. N.B more oil can be added if desired to assist cooling

but never to more than 25mm below the tank lid.

If the pump was supplied full of oil then no further action is necessary.

CONNECTION OF AIR CONTROL PENDANT

The air control pendant has three self sealing quick release connections, one male and two female. The male

connection should be connected to the pendant air supply connection (12) on the pump gauge panel. The female

connectors should be connected to the pendant signal connections (11). One connection controls tool advance and

the other controls tool retract. If the pendant button functions are later found to be incorrect simply swap the

connections.

AIR SUPPLY

An air supply up to a maximum of 10 bar must be connected to the air inlet port (19). However the air regulator (13)

should be adjusted so that the reading on the air pressure gauge (10) is a maximum of 7 bar (100psi). Operating

the pump at above this pressure may result in damage to the motor. The maximum air consumption of the pump is

up to 132m³/h (78 cfm) at maximum pressure and power output. Satisfactory operation can be achieved with lower

flow rates but tool operation will be slower. Add viscosity grade 22 air line lubrication oil, to reservoir (15), via filler

plug adjacent to air lubricator control (14). Do not use hydraulic oil. Adjust the flow of oil using the air lubricator

control to give a drop of oil approx every minute.

CONNECTION OF TORQUE TOOL TO PUMP

Connect the torque tool to the pump using Hi-Force hoses type HTWH. Ensure both halves of the couplers are

clean before connecting.

Connect the female coupler on the red hose to the male tool advance coupler (7). Connect the male end of the

black hose to the female tool retract coupler (8). Connect the other ends of the hoses to the torque tool. N.B. If

using torque tools other than Hi-Force or tools that have been modified, check that the tool is connected correctly

so that the advance pump port is connected to the advance port on the tool. Failure to do this may result in tool

damage or personal injury.

INITIAL OPERATION

Torque wrenches and hoses are not always completely filled with oil when new. For safe and efficient operation the

air must be removed from the system. The following should be carried out with a torque wrench connected to the

pump, but not fitted on a bolt. The torque wrench must be located at a lower level than the pump.

Connect the pump to an air supply. (The motor will not start until a pendant button is pressed.) Adjust the air

regulator control (13) to between 5 and 7 bar, as shown on the air pressure gauge (10).

Press and hold the advance button on the control pendant. The motor will start and the torque wrench should

advance until it reaches the end of its stroke and then the pressure on gauge (5) should start to build up. If the

torque wrench does not advance and pressure is shown on the gauge then it may already be fully advanced. If

there is no pressure registering on the gauge, turn the adjustable pressure relief valve knob (6) clockwise until

pressure shows on the gauge. If the tool retracts, then swap the pendant signal hoses (11).

Press and hold the retract button on the control pendant. The torque wrench should retract until it reaches the end

of its stroke and the pressure should build up to a maximum of 120 bar. If the pressure goes above 120 bar then

the tool is connected the wrong way round. This must be corrected before proceeding otherwise tool damage or

personal injury may result.

Repeat this advance and retract cycle at least 10 times to purge air from the system.
