AIR OPERATED OIL PUMPS
INSTRUCTION MANUAL
The Macnaught 1:1 and 3:1 Ratio Oil Pumps are designed to
dispense lubricating oil, engine oil, gear oil, automatic trans-
mission fluid and anti-freeze/anti-boil or compatible fluids.
GENERAL INFORMATION
Please read this information carefully before use. Your safety
is important to us. Please read and follow all operating and
safety instructions listed below. Make sure all operators have
adequate access to the following instructions.
If you experience problems with this product, refer to the trouble-
shooting section of this manual. If you require further assistance
please contact your local Macnaught Distributor.
IMPORTANT INFORMATION
Do not exceed the maximum recommended air inlet pressure
of 1035 kPa / 150 psi / 10.3 bar. The pumps require a mini-
mum air inlet pressure of 400 kPa / 60 psi / 4 bar and we rec-
ommend that you operate the unit at 690 kPa / 100 psi / 6.9
bar.
Do not hit the unit if it fails to operate.
Use suitable thread sealant ( e.g. Teflon tape ) on all screwed
fittings, but do not over tighten to avoid component damage.
Never allow any part of the human body to come in front of,
or in direct contact with a material outlet.
Never exceed the pressure rating of any component installed
in the system.
Check all hoses for signs of wear, leaks or loose fittings. Tighten
all fluid connections regularly and replace weak or damaged hose.
Your personal safety and well being are at stake.
Before attempting any maintenance or repairs of this product,
disconnect the air supply and release the oil line pressure by
squeezing the hand piece / gun trigger.
ASSEMBLY
Measure the depth of the drum/tank and attach the appropriate
length of threaded pipe to the inlet of the pumps (R100S and
R300S). There are a range of telescopic suction tubes available
from Macnaught.
Remove the bung adapter assembly from the pump and screw it
into the drum/tank opening. Carefully lower the pump through the
bung adapter and tighten the ring nut firmly.
Connect the appropriate hose and / or dispensing equipment to
your pump outlet.
Before connecting the air supply, the user should add a ‘stop’
valve compressed air cock.
Note: The air cock must be a ¼ turn type ( allowing quick
closure ) and should be located close to the body of the
pump and be easily recognized.
Adjust the on/off air valve to regulate the flow. Close the delivery
outlet/nozzle to stop flow.
Note: To protect the pump an in-line oiler must be used. It is
also recommended that a micro-fine (5 micron) air filter is
fitted to the air inlet of the pump to ensure maximum efficien-
cy of the pump.
Do not run the pump dry. Remember to switch off the air supply
to the pump if not using for an extended period of time. (eg. At the
end of each working day)
OPERATION
1) Ensure the drum or tank is “vented”.
2) Partially open the on/off air valve. The pump will prime
automatically.
3) Open the delivery outlet/nozzle. The pump will automatically
start.
4) Adjust on/off air valve to regulate the flow. Close delivery outlet/
nozzle to stop flow.
