HG 55 OIL CONTROL GUN
WITH ELECTRONIC METER
INSTRUCTION MANUAL
INTRODUCTION
Thank you for purchasing a HG55 Electronic oil
control gun. Macnaught oil control guns have been
designed to accurately dispense, measure and control
oil flow. The control guns are suitable with engine oil,
gear oil, automatic transmission fluid, anti-freeze/antiboil and compatible fluids.
Please read and retain this instruction manual to
assist you in the operation and maintenance of this
quality product.
Note: Batteries are not pre-fitted and are included
separately inside the box. Please refer to “Battery
Replacement” on page 3 for correct procedure.
GENERAL INFORMATION
This manual assists you in operating and maintaining your
new oil control gun. The information contained will help
you ensure many years of dependable performance and
trouble free operation.
Please take a few moments to read through this manual
before installing and operating your new oil control gun. If
you experience problems with this product, refer to the
trouble shooting sections of this manual. If you require
further assistance please contact your local Macnaught
distributor or authorised Macnaught service centre.
IMPORTANT INFORMATION
READ THIS INFORMATION
CAREFULLY BEFORE USE.
Your safety is important to us. Please read and follow
all safety instructions listed inside.
Before attempting any repairs or maintenance of this
product firstly disconnect the air supply from the oil
pump, then release the oil line pressure by pressing
the lever on your oil control gun.
ASSEMBLY
Use Teflon tape (or suitable thread sealant ) when
connecting the oil control gun to an oil hose.
Outlet Nozzle.
Some of these instructions alert you to the potential
for personal injury. “Cautions” listed throughout this
manual advise of potential practices or procedures
which may cause damage to your equipment.
The outlet nozzle can be fitted either “inline” (forward) or
on the outlet port “pistol style” located under the gun.
This oil control gun is not designed for in-line
installation. Do not install with a shut-off valve on the
outlet side of the meter. Such an installation could
result in damage to the meter housing cover.
The short adaptor should be used (instead of the long
outlet tube) when using the “pistol style” option.
Ensure all operators have access to adequate
instructions about safe operating and maintenance
procedures.
Do not exceed the maximum working pressure of
10350 kpa / 1500 psi / 103 bar.
CAUTION
Do not hit the oil control gun if it fails to operate. Refer
to “trouble shooting guide” or return the unit to your
nearest authorised service centre.
The long outlet tube should be used for the “inline” option.
Note: Use the threaded Plug supplied to seal the outlet
port not in use.
OUTLET NOZZLE OPERATION
When fluid flows through the gun the outlet nozzle will
automatically open. When the fluid flow stops the outlet
nozzle will automatically shut.
HANDLE OPERATION
To latch the handle, press the lever, push the button and
then release lever.
METER INTRODUCTION
Operating mode description
Never exceed the pressure rating of any component
installed in the System.
Sleep Mode: To minimise battery consumption the meter
will revert to sleep mode if left idle for more than 2 minutes,
and will automatically “power up” if the RESET, button is
pressed or there is flow through the meter.
Before each use check all hoses for signs of wear,
leaks or loose fittings. Tighten all fluid connections
regularly and replace weak or damaged hoses.
The Reset button can be used in two ways:
Press – Press and release the button.
Double click – Press and release the button twice quickly.
Never point the nozzle at yourself or anyone else.
