General Operating Instructions (please read)
• Always operate the compressor within its maximum pressure rating & duty
cycle. Refer to the specications section of this manual for details.
• Your air compressor is equipped with an automatic thermal overload
protector. This feature is designed to protect the air compressor from
over-heating & causing permanent damage to your air compressor. The
thermal overload protector will automatically cut off power to air compressor
should internal operating temperature rise above safe levels during
excessive use.
• Should at any time during usage your air compressor automatically shut
down, do not attempt to restart air compressor. Turn off the power switch. The
automatic thermal overload protector will automatically reset when internal
temperature of the air compressor drops to safe levels. After allowing air
compressor to cool off for about 15 minutes, you can safely resume usage of
the air compressor by turning on the power switch.
• It is strongly recommended that you keep the vehicle’s engine running while
using the air compressor to prevent discharge of your vehicle’s battery. This
means you should ONLY OPERATE THE AIR COMPRESSOR IN WELL VENTILATED
AREAS. Compressor performance is also enhanced when operating with the
vehicle’s engine running.
• Please note that you may experience a slight delay (about 3 sec) to the
compressor’s motor starting when the compressor is pressurised, (i.e. when
there is back pressure in the air line) This is a normal delayed reaction, not a
compressor on/off switch malfunction.
• This compressor is equipped with a built-in pressure switch with a factory set
ON pressure of 120 psi (± 5%) & a factory set OFF pressure of 150 psi (± 5%).
During ination, for pressures between 115 to 150 psi, should ination be halted
momentarily, & compressor does not re-start when tyre ination trigger is
pressed, (normal, since inline pressure is greater than cut-on pressure of the
pressure switch & less than cut-off pressure of the pressure switch) then restart
compressor by deating tyre pressure below 115 psi, & resume tyre ination.
• The air lter must be installed and maintained. The air lter housing has a
screw-on lid to gain access to the replaceable air lter element inside.
• Dirty or clogged lter elements can allow dirt & dust to enter the compressor
and damage internal parts, leading to premature compressor failure or
poor performance. Check air lters regularly and replace when appropriate
according to the condition of the lters and the operating environment.
• Your air compressor is equipped with a permanently lubricated, maintenance
free motor. Never try to lubricate compressor.
• Regularly clean dust & dirt from compressor cooling n s & motor housing.
Before attaching the air compressor’s power cord to the 12 Volt D.C. power
source, check to make sure that the power switch is in the ‘Off’ position. Attach
the Red battery clamp to the Positive terminal of the battery & the Black battery
clamp to the Negative terminal of the battery, ensuring you have made a
good connection. Always keep your vehicle’s engine running while operating
compressor to avoid draining your vehicle’s battery.
Always make sure the portable compressor’s power cord is uncoiled & fully
extended to avoid overheating of the power cord.
The air compressor comes with a heavy duty, heat resistant coiled air hose with
quick connect air outlet ttings & tyre inator/deator.

Tyre Ination
Tyre Deation
Attach one end of hose quick connect coupler to air compressor & the
other end to the Inator/deator gun.
Fit connector onto tyre valve stem.
Check to make sure deator collar lock is disengaged.
Turn compressor switch ‘On’ & hold trigger down to begin ination. When
desired pressure is reached, release trigger.
Pull back rubber surround on digital gauge body to reveal location of
battery cover.
Remove battery cover and t / replace batteries ensuring correct polarity.
Ret battery cover and ensure it is clipped in correctly.
Ret rubber surround to gauge body. Gauge is ready to use.
Remove the temporary protective red plug from the air inlet port.
Screw in the air lter unit & hand tighten. Do not use Teon tape or
lubricants on the thread.
Unscrew the top lid to check if the element is correctly in place.
Fit connector onto tyre valve stem
Press Bleeder Valve button on tyre gun.
When desired pressure is reached, release valve.

The air compressor comes originally packed without the air lter unit installed.
Follow Procedure below for correct installation:
Digital Gauge Battery Replacement
Fitting Air Filter Unit
Note: The trigger lock on the inator gun can be used to allow hands free tyre
ination during long lls. Pay careful attention when using the trigger lock to ensure
that the tyres are not overlled past the manufacturer’s maximum pressure rating
Note: To release pressure, Turn OFF compressor, hold down trigger on tyre gun until
all pressure released. Now disconnect hose.
In-line Presure Gauge
• The large in-line gauge provides convenient monitoring of tyre pressure when
deating or inating. This eliminates switching back & forth between a hand-
held pressure gauge & the compressor.
• Please note that during ination & deation, due to air velocity, the pressure
gauge cannot provide accurate readings. Momentarily stop ination to
obtain accurate pressure readings.
• Do not disassemble. Do not attempt repairs or modications. Your warranty
will be void if this instruction is ignored.
• Do not use this product in an area where it can fall or be pulled into water or
other liquids.
• The base tray is tted to place a barrier between the compressor & sandy or
dusty ground, plus provide a stable operating platform, therefore keep the
tray clean at all times during use.
• Use this compressor with 12Volt DC power only.
• This product should never be left unattended during use.
• Pay careful attention when using the trigger lock on the inator gun to ensure
that the tyres are not overlled past the manufacturer’s maximum
pressure rating.

Warning: To prevent injuries
• Parts of this compressor will become very HOT during & immediately after use.
Do not touch any of these parts with your bare hands as you could receive a
severe burn.
• Never allow children to operate this compressor. Close supervision is
necessary when this compressor is being used near children.
• Do not pump anything other than atmospheric air.
• Do not use any other tools or attachments without rst determining maximum
air pressure for that tool or attachment.
• This air compressor is equipped with an Automatic Reset Thermal Protector, &
can automatically restart after the thermal protector resets. Always turn off
the power when thermal protector becomes activated.
• Never Point any air nozzles toward another person or any part of the body.
• After use, always release pressure from the hose by turning ON/OFF switch to
OFF. Press trigger on the tyre gun – this releases pressure in system. Disconnect
hose & gun.
• Exercise extreme caution & never exceed 40 KPH when driving with
deated tyres.
• Never make sharp turns while driving with reduced tyre pressure as you could
break the ‘bead’ between the wheel rim & the tyre.
• Re-inate tyres to manufacturer’s recommended tyre pressure before high
speed travelling on roadways.
