the air regulator anticlockwise to reduce the air pressure to zero. Then turn on the air supply and slowly increase the air pressure by
turning the knob clockwise until the pump just ticks over. Draw a small amount of oil into the container until all air is expelled. Tighten
outlet nut.

Any air left in the oil pumping system can usually be eliminated by holding the gun trigger open and operating the pump until oil emerges
free of all air. If a pipeline has been installed between the pump and the reel it may be necessary to bleed the fittings on this line to finally
eliminate all air.
5.22
Once the oil system has been purged of air the air pressure can be gradually increased to the everyday working pressure of 6bar.
Check that there are no air leaks from any of the air hoses or fittings.
6. OPERATING INSTRUCTIONS
6.0
Setting up the dispensing gun with digital meter.
By repeatedly pressing the FUNCTION button you will cycle through the three modes of operation
available. Stop on whichever of the three modes you require. See below for an explanation of the
modes.
Single operation (S.o.t.) This mode is intended for a single dispensing operation of a known
quantity of oil in litres.To use this mode repeatedly press the FUNCTION button until the letters
S.o.t. appear on the display. After a few seconds the display automatically reverts to a digital
readout. If the display is not at zero press the RESET button. Squeeze the trigger to commence
filling. Keep the trigger depressed until the display indicates the required quantity then release.
When the trigger is pressed again in this mode the display will automatically return to zero.
Partial operation ( P.t.) In this mode the display will not return to zero after a dispensing operation but will add the next
dispensed quantity to the previous total. Thus this mode could be used to record the total amount of oil dispensed in any period
of time such as daily or weekly. Once the reset button is pressed in this mode the display returns to zero. To set this mode
repeatedly press the FUNCTION button until the display shows the letters P.t.
Absolute operation ( A.t.) This mode is a reference mode only and shows the the total amount dispensed in litres from first
use. This mode cannot be reset. When 999.9 litres have been dispensed the display starts again from zero. To see this mode
repeatedly press the FUNCTION button until the letters A.t. appear.
6.1
To dispense oil. For safety reasons the system is not designed to fill at high speed. The end of line flow rate will vary
depending on a number of factors including length of line, temperature, air pressure and viscosity of oil.
6.2
Pull the hose from out of the hose reel and place the digital dispensing gun in a convenient place. Set the required dispensing
mode up on the digital display as described above.
6.3
Ensure that the shut off valves on the pump and on the hose reel are open.
6.4
Before turning on the air supply rotate the knob on top of the air regulator anti-clockwise to set an air pressure less than 6bar.
Now turn on the air supply and screw the air regulator knob clockwise to gradually work up to a pressure of 6bar. The pump will
start to operate at about 2bar and will continue to run until the set pressure is reached within the system.
6.5
Before commencing to fill the vehicle with oil ensure that you know the capacity of oil required.
6.6
Remove the filler cap and place the trigger nozzle into the aperture. Squeeze the trigger to commence filling with oil. When the digital
display indicates the required amount release the trigger. When a large amount of oil is to be dispensed the trigger can be locked in
the on position by swinging the wire trigger lock over the end of the trigger lever. To release the lock sqeeze and hold the trigger and
swing the wire clip out of the way.
6.7
When filling is complete replace the filler cap.
6.8
Retract the hose into the reel by giving a sharp pull on the hose close to the reel. Do not allow the retracting hose to drag the
dispensing gun over the floor or return unaided.
6.7
When filling operations are complete turn the air supply off. Keep the system clean, especially the dispensing gun and nozzle.
