GLOSSARY
CFM: Cubic feet per minute.
SCFM: Standard cubic feet per minute; a unit of measure
of air delivery.
PSIG: Pounds per square inch gauge; a unit of measure
of pressure.
CUT-IN PRESSURE: While the motor is off, air tank
pressure drops as you continue to use your accessory or
air tool. When the tank pressure drops to a certain level
the motor will restart automatically re-started is called
“cut-in pressure”.
CUT-OUT PRESSURE: When you turn on your air
compressor, it begins to run, air pressure in the air tank
begins to build. It builds to a certain pressure before the
motor automatically shuts off - protecting your air tank
from pressure higher than its design rating. The pressure
at which the motor shuts off is called “cut-out pressure”.
DUTY CYCLE
All Makita manufactured air compressors are
recommended to be operated on not more than a 50%
duty cycle. This means an air compressor that pumps air
more than 50% in one hour is considered misuse because
the air compressor is undersized for the required air
demand.
GENERAL INFORMATION
This air compressor is equipped with an Oil-Less pump
designed for durability and no maintenance.
The compressor can be used for properly rated pneumatic
nailers and staplers. An air pressure regulator is supplied
for these applications.
WARNING
Never use compressor for applications other than to
operate a properly rated nailer or stapler. Use of the
compressor for other applications could result in property
damage and personal injury.
Separate air transformers which combine the functions of
air regulation and/or moisture and dirt removal should be
used where applicable.
ON-RECEIPT INSPECTION
DAMAGE: Each air compressor outfit is carefully tested
and checked before shipment. With improper handling,
damage may result in transit and cause problems with
compressor operation.
Immediately upon arrival, check equipment for both
concealed and visible damages to avoid expenses being
incurred to correct such problems. This should be done
regardless of any visible signs of damage to the shipping
container. If this product was shipped directly to you,
report any damages to the carrier and arrange for
inspection of goods immediately.
STORAGE
Before you store the air compressor, make sure you do
the following:
1. Review the “Maintenance” and “Operating
Procedures” sections and perform maintenance as
necessary. Be sure to drain water from the air tank.
2. Protect the electrical cord and air hose from damage
(such as being stepped on or run over).
Store the air compressor in a clean and dry location.
DESCRIPTION OF OPERATION
DRAIN VALVE: The drain valve is located at the bottom of
the air tank and is used to drain condensation at the end
of each use.
THERMAL CIRCUIT BREAKER:
The electric motor has a manual reset thermal circuit
breaker. If the motor overheats for any reason, the circuit
breaker will shut off the motor. Turn pressure switch to the
“off” position and wait for unit to cool before pushing the
reset button and restarting the compressor.
MOTOR THERMAL OVERLOAD
PROTECTOR:
When the current rating of the motor is exceeded the
thermo-protector will open and shut off the motor
automatically.
The motor must be allowed to cool down before restarting.
The compressor will automatically restart after the motor
cools down.
ON/AUTO - OFF SWITCH:
Turn this switch to “on” to provide automatic power to the
pressure switch and to “off” to remove power when
finished using the compressor or when compressor will be
left unattended.
AIR INTAKE FILTER:
This filter is designed to clean air coming into the
compressor pump. This filter must always be clean and
free from obstructions. See “Maintenance”.
AIR COMPRESSOR PUMP:
To compress air, the piston moves up and down in the
cylinder. On the down stroke, air is drawn in through the
air intake valve. The exhaust valve remains closed.
On the upstroke of the piston, air is compressed. The
intake valve closes and compressed air is forced out
through the exhaust valve, through the outlet tube,
through the check valve and into the air tank. Useable air
is not available until the compressor has raised the air
tank pressure above that required at the air outlet.
CHECK VALVE:
When the air compressor is operating, the check valve is
“open”, allowing compressed air to enter the air tank.
When the air compressor reaches “cut-out” pressure, the
check valve “closes”, allowing air pressure to remain
inside the air tank.
PRESSURE SWITCH UNLOADING VALVE:
The pressure switch unloading valve located on the side
of the pressure switch, is designed to automatically
release compressed air from the compressor head and
the outlet tube when the air compressor reaches “cut-out”
pressure.
PRESSURE SWITCH:
The pressure switch automatically starts the motor when
the air tank pressure drops to the factory set “cut-in”
pressure. It stops the motor when the air tank pressure
reaches the factory set “cut-out” pressure.
SAFETY VALVE:
If the pressure switch does not shut off the air compressor
at its “cut-out” pressure setting, the safety valve will
protect against high pressure by “popping out” at its
factory set pressure which is slightly higher than the
pressure switch “cut-out” setting.
OUTLET PRESSURE GAUGE:
The outlet pressure gauge indicates the air pressure
available at the outlet side of the regulator. This pressure
is controlled by the regulator and is always less or equal
to the tank pressure. See “Operating Procedures”.
TANK PRESSURE GAUGE:
The tank pressure gauge indicates the air pressure in the
tank.
REGULATOR:
The air pressure coming from the air tank is controlled by
the regulator knob. Turn the knob clockwise to increase
pressure and counter-clockwise to decrease pressure. To
avoid minor re-adjustment after making a change in
pressure setting, always approach the desired pressure
from a lower pressure. When reducing from a higher to a
lower setting, first reduce to some pressure less than
desired pressure. Depending on the air requirements of
each particular accessory, the outlet regulated air
pressure may have to be adjusted while you are operating
the accessory.

INSTALLATION AND BREAK-IN
PROCEDURES
LOCATION OF THE AIR COMPRESSOR
Locate the air compressor in a clean, dry and wellventilated area. The air filter must be kept clear of
obstructions, which could reduce air delivery of the air
compressor. The air compressor should be located at
least 12 inches away from the wall or other obstructions
that will interfere with the flow of air. The air compressor
head and shroud are designed to allow for proper cooling.
If humidity is high, an air filter can be installed on the air
outlet adapter to remove excessive moisture. Follow the
instructions packaged with the air filter for proper
installation.

Extension Cords
To avoid voltage drop, power loss, and overheating of the
motor, use extra air hose instead of an extension cord.
Low voltage can cause damage to the motor.
If an extension cord must be used:
• Use only an approved 3-wire extension cord that has a
3- blade grounding plug and a 3- slot receptacle that
will accept the plug on the air compressor.
• Make sure the extension cord is in good condition.

Piping
Plastic or PVC pipe is not designed for use with
compressed air. Regardless of its indicated pressure
rating, plastic pipe can burst from air pressure. Use only
metal pipe for air distribution lines. If a pipe line is
necessary, use pipe that is the same size, or larger than,
the air tank outlet. Piping that is too small will restrict the
flow of air. If piping is over 100 feet long, use the next
larger size. Bury underground lines below the frost line
and avoid pockets where condensation can gather and
freeze. Apply pressure before underground lines are
covered to make sure all pipe joints are free of leaks.
Grounding Instruction
WARNING: Risk of electric shock! In the event of a short
circuit, grounding reduces the risk of shock by providing
an escape wire for the electric current. This air
compressor must be properly grounded.
The air compressor is equipped with a cord having a
grounding wire with an appropriate grounding plug. The
plug must be used with an outlet that has been installed
and grounded in accordance with all local codes and
ordinances. The outlet must have the same configuration
as the plug. DO NOT USE AN ADAPTER.
Inspect the plug and cord before each use. Do not use if
there are signs of damage.
DANGER:
Improper grounding can result in electrical shock. Do not
modify the plug that has been provided. If it does not fit
the available outlet, the correct outlet should be installed
by a qualified electrician.
