cooling . If humidity is high, an air filter can be
installed on the air outlet adapter to remove
excessive moisture. Follow the instructions pac-
kaged with the air filter for proper installation.
TO START & STOP THE COMPRESSOR
1. Check the rating label on the compressor in-
dicates 127 V.
2. Plug in the mains cable of the compressor to
a standard 127 V household power point and
turn on.
3. To start the compressor, lift the ON/OFF switch
on the pressure switch cover.
4. To stop the compressor, push the ON/OFF
switch down.
DUTY CYCLE
All Makita manufactured air compressors are re-
commended to be operated on not more than
a 60% duty cycle. This means an air compressor
that pumps air more than 60% of one hour is
considered misuse because the air compressor is
undersized for the required air demand .
OPERATION
1. The pressure in the tank is controlled by the
action of the pressure switch located under the
pressure switch cover. When the set maximum
pressure is reached the pressure switch activates
and the motor is switched off.
The pressure then decreases as the air is used by
the connected tool until the set minimum pres-
sure is reached after which the pressure switch
causes the motor to switch on again.
The operator of the compressor should be well
aware that during use of the compressor the
motor will start and stop under the influence
of the rising or falling pressure in the tank. The
motor will start without any warning.
2. The maximum and minimum pressures are
factory set and the operator should not try to
change them.
3. All accessories are connected to the regulated
outlet valve.
4. The pressure of the regulated outlet, as
shown on the regulated outlet pressure gauge,
can be changed by turning the regulating knob.
NOTE: to obtain the correct output reading on
the regulated output gauge, the air must be
flowing through the outlet.
The regulating valve should be adjusted and the
gauge read with the outlet valve open and the
air being discharged from the regulated outlet
through the accessory being used.
To increase the air pressure, rotate the regulat-
ing valve clockwise. To decrease the pressure,
rotate the regulating valve anti-clockwise.
NOTE: if you do not allow the air to discharge
E S P A Ñ O L •
while you are setting the regulator, the pressure
as indicated on the regulated outlet gauge will
be incorrect. This gauge ONLY indicates the cor-
rect pressure while air is being discharged from
the outlet.
5. On completion of the task, i.e. when you have
finished using the compressor, or when you are
leaving the compressor unattended, turn off the
compressor in the following way:
• Press down the on/off switch.
• Wait for the pressurised air to bleed from the
release valve under the pressure switch cover.
NOTE: when you press the button down you
should hear a short air discharge (approximately
1/2 second).
• Switch off the electrical power supply and re-
move the electrical plug.
• Pull the ring (Fig.11) on the safety valve to en-
sure all the pressurised air is released from the
tank, or open the drain cock to release the pres-
sure from the tank.
ADDITIONAL WARNINGS
1. Never attempt to remove any part of the com-
pressor whilst the tank is under pressure.
2. Never attempt to remove any electrical com-
ponent whilst the compressor is connected to
the power supply. Switch off the power and re-
move the electrical plug.
3. Do not adjust the safety valve.
4. Do not use an electrical extension cable.
5. If the release valve under the pressure switch
cover fails to operate when the on/off button is
pressed down, switch the power supply off and
determine the nature of the fault.
6. Ensure that the lubricating oil is clean and
that the oil level is maintained at the mid point
of the red circle in the oil level glass.
7. Take care when discharging air from the tank,
i.e. from the safety valve, the drain cock or the
air outlet.
Compressed air can be extremely dangerous.
Take care the discharge air does not cause dust,
stones or any other foreign particles to be blown
through the air and that the air is discharged in
a safe manner.
MAINTENANCE
WARNING: UNIT CYCLES AUTOMATICALLY
WHEN POWER IS ON. WHEN DOING MAINTE-
NANCE, YOU MAY BE EXPOSED TO VOLTAGE
SOURCES, COMPRESSED AIR OR MOVING PARTS.
PERSONAL INJURIES CAN OCCUR. BEFORE PER-
FORMING ANY MAINTENANCE OR REPAIR, UN-
PLUG THE COMPRESSOR AND BLEED OFF ALL
AIR PRESSURE.
