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.
4.2
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.
4.3
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.

Using the dispensing gun with digital meter.
6.1.
RESET BUTTON. To dispense a specific amount of oil press the 'reset' button to 'zero' the display. As oil is dispensed the
display shows the amount of oil dispensed so far as a rolling total. Release the trigger when the display reaches the required
amount. If the display is not reset every time oil is dispensed the display will show the accumulative amount since the display
was last reset.
6.1.2
TOTAL BUTTON. The 'total button' changes the display to show the total amount of oil dispensed from first use. This total
cannot be reset. If records are kept the user can check the amount of oil dispensed over a particular period of time i.e.
day/week/month/year.
6.1.3
SECONDARY BUTTONS. Two buttons (1 & 2) for secondary functions can be found on the back of the display moulding as
shown in fig.4. Button1 is used to set the accuracy of the meter and to change the units of measurement. Button 2 reactivates
the display should it appear dead.To access these buttons remove the screws from the sides of the display moulding (2 each
side) and lift off the display.
6.1.4
SETTING ACCURACY. Different temperatures and fluid viscosity will affect the meter accuracy. This can be adjusted to give a
figure of plus or minus 0.5%. To check the accuracy dispense one litre of oil into a measuring vessel and check against the
1 litre mark. To see the current correction factor hold TOTAL & RESET both together for 5 seconds. To change the correction
factor hold button 1 down for one second. Use the TOTAL button to select the digit to be altered and use the RESET button to
step through the numbers 0 to 9 until you reach the one you want. Press TOTAL again to move to the next digit. To exit this
mode press 1 again for 1 second.
6.1.5
CHANGING THE UNITS OF MEASUREMENT. Hold down button1 for 1 second. Use the TOTAL button to step across the digits
in the display until the unit of measurement symbol on the right of the display is flashing. Use the reset button to select one of
the four units of measurement. To exit this mode press 1 again for 1 second.
