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).
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.
4) Lift handle to transfer power head from
stem to stem
1) Attach power head to stem
3) Press or Release trigger to adjust flow

IMPORTANT INFORMATION
PLEASE READ THIS INFORMATION CAREFULLY
BEFORE USE.
Read and retain this instruction manual to assist you
in the operation of this product.
If you have any problems with the meter, refer to the
maintenance and trouble shooting sections of this
manual.
If you need further assistance, please contact your
local representative or distributor for advice.
OPERATING PRINCIPAL
WARNING
This Flow Meter has incorporated the oval rotor prin-
cipal into its design. This has proven to be a reliable
and accurate method of measuring flow.
Exceptional repeatability is the feature of the oval
rotor design.
This product should only be used with automo-
tive oils and lubricants
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 sen-
sors.
A signal is generated which is then sent by the PCB
to the LCD as a Pulse Output.
* Macnaught recommends the use of PPE
equipment such as safety glasses, protective
gloves, safety shoes etc before handling or
using this product.
* Do not modify or alter this product any way
* Ensure that any fluid spillage is cleaned up
immediately to prevent slipping or injury.
* Firmly tighten all connections and check for
any sign of leakage before use.
