DISCLAIMER Your product is designed to use with non-flammable automotive oil/lubricants only, with viscosity grades from 0W-40 to SAE85W-140. Usage with different fluids may cause performance degradation and render the warranty void. Improper use of liquid may lead to machine failure and malfunction.
Use of any flammable fluids can cause sparks to explode and create a fire hazard. Macnaught bears no liability to the consequence of fluid misuse by customers.
WARNING
Always place gun on hanger when pump is not in use, as oil spillage can cause a slipping hazard. Keep plastic bag away from babies and children. Do not lift the power head with locking lever. Handle power head with care. DO NOT DROP. Make sure the power head is securely connected/attached to the stem. Do not leave the power head sitting on top of the stem unlocked. Stop operating the battery oil pump if any leakings at the joints are noticed. Do not modify the pump in any way. Only use a genuine Macnaught dispensing gun. Hand tighten the hose till its firm and check for any signs of
leakage before use.
Do not use flammable fluid in this product. Only use fluid specified in this instruction manual. Wear appropriate PPE for protection. Do not use the product in potentially explosive atmosphere. Do not expose the product to fire and source of heat. Users should refer to MSDS of the fluid from supplier being used. Use product in well ventilated area. Never leave your dispensing gun unattended in open position. Do not attempt to use any means to lock the
lever. Always ensure the switch is in off position after dispensing the oil.
Use pump in adequate lighting condition for safe operation. Do not use the product under poor illumination. Avoid spillage of oil near water source as it may be harmful to the environment. When moving drum, check area for spillage and clean up any liquid on floor as this will cause a slippery
hazard Only use genuine Macnaught battery and chargers with this product. Battery pack, charger and power head should be protected from water.
CAUTION

• Do not expose the power head to a nearby magnet as its performance will be adversely affected.
  The battery operated pump should always be used in a vertical position.
  The dispensing gun should always be facing up when dispensing fluid.
  If the noise level changes check the hose to see if there is air present, if air is present stop the pump immediately as this indicates the drum is empty. Switch over to a new drum.

OPERATING INSTRUCTIONS OPERATION
CAUTION NOTE: Do not allow the pump to run dry or pump damage can occur

IMPORTANT: For initial operation

1. Turn slot in shaft clockwise one complete turn with a flat head screwdriver.
2. First press the trigger on gun and then turn on the pump to prime.
3. Release trigger when primed (fluid flows from gun). 4) Power head can be moved from pump assembly to pump assembly.
4. Long storage periods : a) Turn slot shaft 2 full turns counter clockwise using a flat head screwdriver. b) When starting pump after a long storage period, turn slot shaft clockwise with a flat head screwdriver.
   Note: Pump will not run when power head is not attached to pump stem correctly.
   Pressure sensor will turn motor off when trigger is released and stall pressure is reached.
   For low viscosity oils you may need to manually prime the system before use
   Note: There may be a delay in the pump turning off when the trigger on the gun is released, this is normal as the pump is priming to stall pressure.

GENERAL OPERATION 1) Attach power head to stem
CAUTION 2) Remove nozzle cover before use

  OPERATING PRINCIPAL
  When fluid passes through the meter the rotors turn, as shown below. The magnets which are located in the rotors will pass across the PCB sensors. A signal is generated which is then sent by the PCB to the LCD as a Pulse Output.

METER TO GUN ASSEMBLY

1. Prior to assembling connector (2) to the gun (1) remove item (5) from the gun (1).
2. Screw item (2) to the gun outlet (1) – Do not over tighten.
3. Slide O’ring (6) all the way onto screw (2)
   6 2 3 4) Remove the U’clip (3) from the meter (4) 5) Insert the meter inlet (4) onto the connector (2) apply light pressure to the meter, this will slightly compress the O’ring (6) then firmly press in theU’ clip until flush with the body (3) as shown 6) Carefully screw the outlet tube (5) onto the meter outlet (4) – Do not over tigthen
