Operating Instructions
Please read and save these instructions before attempting to assemble, install, operate or maintain
the product. Protect yourself and others by observing all safety information. Failure to comply with
instructions could result in injury and/or damage!
DESCRIPTION
Oil-less compressors are designed for DIY
(do-it-yourselfers) for a variety of home uses
and operate without oil. Compressed air
units contain moisture, therefore ensure you
install a water filter or air dryer if your
application requires dry air.
SAFETY GUIDELINES
This manual contains useful information for
the safe use and maintenance of your
compressor. Please observe any of the
safety recommendations.
UNPACKING
After unpacking the unit, carefully inspect it
for any damage that may have occurred
during transit. If you have any concerns
please contact your supplier prior to use.
GENERAL SAFETY INFO
Air compressors and tools (spray guns,
filters, lubricators, hoses, etc.) produce and
require compressed air for them to operate.
Ensure to:-
1. Read all tool
manuals and be
thoroughly familiar
with the controls and
the proper use of the equipment.
2. Keep visitors away and NEVER allow
children in the work
area.
3. Wear safety glasses
and use ear protection..
4. Do not stand on or
operate the unit whilst handheld from the
handle.
5. Prior to each use inspect the air system
and electrical components for signs of
damage, deterioration, weakness or
leakage, Repair or replace defective items
before using.
6. ▲WARNING!
Never operate or repair
in or near a flammable
gas or vapor. Never store flammable
liquids or gases in the vicinity of the
compressor.
7. ▲CAUTION!
Compressor parts may be
hot even if the unit is
stopped.
8. ▲WARNING!
Never remove or attempt to adjust the
pressure release valve. Ensure it is kept
clean and free from any contamination.
9. ▲DANGER!
Never attempt to repair or
modify a tank! Welding or
any modification may weaken the tank
resulting in damage, rupture or
explosion. Always replace a worn or
damaged tank.
10. ▲WARNING!
Tanks rust from moisture build-up,
which weakens the tank. Make sure to
drain tank regularly and inspect
periodically for unsafe conditions such
as rust formation and corrosion.

12. LOCATION
It is extremely important to install the
compressor in a clean, well-ventilated area.
The surrounding air temperature should not
be more than 100°F.
A minimum clearance of 18 inches between
the compressor, a wall or any other obstacle
is required so as not to obstruct the airflow to
the unit.
13. ▲CAUTION!
Never use an extension
cord with this product.
Use additional air hose to reach your
work area, this is to avoid power loss
and possible motor damage; Use of an
extension cord voids the warranty.
14. OPERATION
a) The red button on top of the pressure
switch is the main ON/OFF control. With
the button pressed down the compressor
will operate and fill the tank with air. Once it
has reached capacity it will automatically
switch off. In the position the compressor
will automatically switch on and off to keep
the tank filled with air. To switch OFF the
compressor pull the red button in an
upward direction.
b) The regulator controls the amount of air
pressure required. Turning the regulator
clockwise increases the pressure,
anticlockwise decreases the pressure to
the required level for the tool being used.
c) The safety valve automatically releases air
if the tank pressure exceeds the preset
maximum.
d) Ensure the compressor has had time to
fill the tank and warm up prior to initial use.
e) The tank pressure gauge shows
pressure level in the tank.
f) ▲CAUTION!
The compressor is equipped with an
automatic reset thermal overload
protector; this will shut off the motor if it
becomes overheated. If the thermal
overload is activated turn off the
compressor and unplug from the mains.
The motor must be allowed to cool
down before start-up is possible.
TROUBLESHOOTING CHART
