USER GUIDE
Congratulations on the purchase of a PILOT air compressor. This
unit has been designed to provide reliable and trouble free usage
in servicing your compressed air requirements.
Please take a moment to familiarise yourself with the
information contained in the following sections of this guide
before attempting to operate this unit.
LOCATION OF UNIT
For optimum efficiency locate unit in a clean, dry and cool
environment with good ventilation. Avoid placing obstacles
either on or around unit to facilitate maximum air flow and
cooling.
CHECK OIL LEVEL BEFORE USE IN CASE OF LOSSES
INCURRED DURING SHIPPING

OPERATION
ELECTRIC UNITS
Ensure ON/OFF switch is located on the pressure switch is in an
OFF position (down), before inserting power plug into appropriate
power point and applying power.
Unit can then be switched on using the ON/OFF switch. The
pressure switch will automatically start and stop the compressor
when the air receiver drops below or reaches factory set cut-in
and cut-out pressures respectively.
ALWAYS SWITCH UNIT ON AND OFF VIA
PRESSURE SWITCH TO ENSURE THE UNIT
DOES NOT START AGAINST HIGH PRESSURE
TO PREVENT DAMAGE TO UNIT OR PERSONS DO NOT
ATTEMPT TO MODIFY, BYPASS OR REMOVE PRESSURE
SWITCH OR SAFETY VALVE IN ANY WAY.
“TM” OR “K” SERIES ARE DESIGNED TO OPERATE TO
A MAXIMUM PRESSURE OF 10 BAR.
The air receiver is equipped with a safety valve to release
pressure in the event of a pressure switch cut-out failure. To
prevent damage to the unit, do not attempt to modify, bypass or
remove the pressure switch or safety valve in anyway.
The motor features a manual overload protection (where fitted).
In poor power conditions or motor over temperature conditions,
this overload protector will cut power to the motor. To reset,
wait for the motor to cool then press reset button. If problems
persist, check for power ratings, faulty power or poor
connections.

PETROL /DIESEL DRIVEN UNITS
Please refer to OEM documentation in reference to care and
operation of your petrol/diesel engine.
This unit has been designed to “idle down” to minimum operating
speeds when factory set cut-out pressures are reached. This
saves both fuel consumption and wear on moving parts. When
pressure drops to set cut-in pressures the unit will automatically
resume pumping at normal operating speeds.
To facilitate easy starting of the unit and to ensure no damage to
the electric starter (where fitted) always open the “EASY START”
valve until the unit is operating and then close for normal
operation. This valve is located on the motor/pump platform
(models K25P,K30P) or in the discharge pipe from the pump to
the air receiver (other models).
For Petrol powered units fitted with electric start capability:
Honda Australia recommends the following specification for
wiring to a battery: Max. Cable length: 1.5 M, Cable size: 8
mm/sq. Over 1.5 M in length requires cable size of 15 mm/sq
SAFETY
Pressure vessels (air receivers) are a type of plant,
and as such, MAY be required to be registered with
the relevant statutory authority in your state.
Regulations regarding plant registration vary from
state to state. Check with your relevant government
authority about plant registration.
Compressed air can be dangerous. Never point
compressed air tools or equipment towards another
person.

After use, drain all residual air pressure or engage
outlet tap to prevent accidental discharge by children.
Keep clear of compressor pump during and after
operation. Heat build up in the pump may cause burns
to unwary.
Never operate the unit without factory fitted belt
guard.(belt drive models) or pump shroud (direct drive
models).
Never operate the unit with damaged or exposed
electrical wiring.
Do not alter, adjust or remove any components on the
unit without technical support from Pilot Air or an
authorised Pilot Air agent
Whenever transporting an air compressor, ensure all
air is drained from the air receiver. There should be NO
residual air pressure in the air receiver.

MAINTENANCE INSTRUCTIONS
Check that fuses or circuit breakers correspond to motor rating. In
case of 415-Volt units, check rotation as indicated by arrow
attached to unit. On 240-Volt units, avoid using extension leads as
they could cause voltage drop and power loss to motor. If extension
is to be used, please follow the table below.
TABLE 1.
KW HP VOLTS RECOMMENDED WIRE SIZE
1.65 2.25 240 HEAVY DUTY, 1.5MM SQUARE WIRE (MAX LENGTH 20 M)
2.20 3.00 240 HEAVY DUTY, 1.5MM SQUARE WIRE (MAX LENGTH 10 M)
Oil level should be at the centre of the oil sight glass on the
compressor pump. Do not overfill as this could cause excessive oil
being expelled from the crank case breather.
Oil is to be replaced every 1000 working hours or on a six (6)
monthly basis. Recommended oil:
PILOT PCO-40G or equivalent (Stationary models).
PILOT PCO-30G or equivalent (Portable models).
Note: In humid and/or very low duty cycle environments,
condensate may collect in the sump. Under these conditions, it is a
requirement that the operator drain the residual water from the
sump on a regular basis and/or change the oil more frequently than
recommended above.
Whenever transporting an air compressor, ensure all air is drained
from the air receiver. There should be NO residual air pressure in
the air receiver.
Routine maintenance should be performed on at least a six (6)
monthly basis.
Condensation must be drained from air receiver at least weekly.

p : 1300 667 579
www.pilotair.com.au
Unit must be kept clean to allow proper cooling to take effect.
Special care should be taken to clean the crankcase breather in
order to allow proper crankcase breathing.
Whenever attempting to carry out any maintenance to compressors,
isolate power and release all pressure from receiver.
For information regarding spare parts and/or service, please always
quote model and serial number.
PLEASE KEEP THIS INFORMATION NEAR MACHINE, SO IT CAN BE
READ BY ANYONE ATTEMPTING PREVENTATIVE MAINTENANCE.
DO NOT BOLT COMPRESSOR DIRECTLY ONTO FLOOR. THIS MAY CAUSE
CRACKS IN THE AIR RECEIVER. IF THE COMPRESSOR MUST BE BOLTED,
ENSURE RUBBER VIBRATION PADS ARE IN PLACE AND FASTEN, LEAVING
A GAP BETWEEN BOLT HEAD OR NUT AND COMPRESSOR FOOT TO AVOID
ANY METAL TO METAL CONTACT.

COMPRESSOR COMPONENT DESCRIPTIONS
PRESSURE SWITCH (240V & 415V models only): This switch is
located on the top of the air receiver and functions as a manual
on/off switch in addition to automatically stopping and starting the
compressor at factory pre-set pressures (electric models only).
PRESSURE GAUGE: The Pressure Gauge is located on the air
receiver and indicates the pressure held in both PSI and KPA.
SAFETY VALVE: The Safety Valve is located on the air receiver and
is designed to release pressure in the event of a pressure switch
failure.
OVERLOAD PROTECTION: Electric models are fitted with an
overload protector, to protect the motor in the event of an over
temperature condition. These reset buttons are located either on
the pressure switch or the motor itself.
CHECK VALVE (240V & 415V models only): The Check Valve is
located at the junction of the pump discharge pipe and the air
receiver. The check valve prevents air pressure returning from the
air receiver to the pump.
EASY START VALVE: (Petrol/Diesel models only) The Easy Start
Valve is located on the check valve for portable units and on the
compressor platform for stationary units. This valve should be
opened for ease of starting of the engine and closed when running
for normal operation.
RECEIVER DRAIN: The Receiver Drain is located at the underside of
the air receiver and is used for draining condensate from the
receiver.
OIL SIGHT GLASS: The Oil Sight Glass is located on the side of the
compressor pump (opposite the flywheel) and is used for examining
the oil level of the unit.
