DUTY CYCLE
GENERAL INFORMATION
ON RECEIPT INSPECTION
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".
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% of one hour is
considered misuse because the air compressor is undersized for the required air demand.
This air compressor requires oil. Now you can enjoy all the benefits of having an oil lubricated
professional air compressor. When oil is changed regularly, it will give you long, trouble-free life.
Your air compressor can be used for operating paint spray guns, air tools, caulking guns, grease
guns, air brushes, sandblaster, inflating tires or spraying weed killers, insecticides, etc. An air
pressure regulator is supplied for these applications.
Separate air transformers which combine the functions of air regulation and/or moisture and dirt
removal should be used where applicable.
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

DESCRIPTION OF OPERATION
product was shipped directly to you, report any damages to the carrier and arrange for
inspection of goods immediately.
Before you store the air compressor, make sure you do the following:
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.
MOTOR THERMAL OVERLOAD PROTECTOR: The electric motor has a manual thermal
overload protector. If the motor overheats for any reason, the thermal overload protector 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.
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.
Review the “Maintenance” and “Operating Procedures” sections and perform
maintenance necessary.Be sure to drain water from the air tank.
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.

MAKITA - MAC700 / MAC2400 / MAC5200
DESCRIPTION OF OPERATION ... Continued
INSTALLATION AND BREAK-IN PROCEDURES
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 (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.
LOCATION OF THE AIR COMPRESSOR:
Locate the air compressor in a clean, dry and well-ventilated 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.
LUBRICATION AND OIL:
CAUTION: Do not attempt to operate this air compressor without first adding oil to the
crankcase. Serious damage will result from even limited operation unless filled with oil and
broken in correctly. Make sure to closely follow initial start-up procedures. Compressor oil is
provided; on a level surface, please fill the crankcase to proper level indicated on the sight glass.
WARNING: Compressors are shipped without oil. A small amount of oil may be present in the
pump upon receipt of the air compressor. This is due to factory testing and does not mean the
pump contains oil.

CAUTION: Multi-Viscosity motor oils, like 10W30, should not be used in an air compressor. They
leave carbon deposits on critical components, thus reducing performance and compressor life.
Use air compressor oil only.
Initial Start Up Procedure:
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:
Please see the chart below as the MINIMUM requirements:
Open the air receiver's drain valve.
Plug power supply cord into correct power source.
Run the compressor for a minimum of twenty (20) minutes in the no-load
condition to lubricate the bearings and pistons, and to seat the piston rings.
Close air receiver drain valve. Your compressor is now ready for use.

OPERATING PROCEDURES
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 if 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.
Daily Start-Up Checklist:
Before attaching air hose or accessories, make sure the pressure switch lever
is set to “OFF” and the air regulator or shut-off valve is closed.
Attach hose and accessories. Too much air pressure causes a hazardous risk
of bursting. Check the manufacturer's maximum pressure rating for air tools
and accessories. The regulator outlet pressure must never exceed the
maximum pressure rating.
Turn the pressure switch lever to “ON/AUTO” and allow tank pressure to build.
Motor will stop when tank pressure reaches “cut-out” pressure.
Open the regulator by turning it clockwise. Adjust the regulator to the correct
pressure setting. Your compressor is ready for use.
Always operate the air compressor in well-ventilated areas; free of gasoline or
other solvent vapors. Do not operate the compressor near the spray area.

WARNING
Some dust created by power sanding, sawing, grinding, drilling, and other construction activities
contains chemicals known to the State of California to cause cancer, birth defects or other
reproductive harm. Some examples of these chemicals are:
• lead from lead-based paints,
• crystalline silica from bricks and cement and other masonry products, and
• arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how often you do this type of work. To
reduce your exposure to these chemicals: work in a well ventilated area, and work with
approved safety equipment, such as those dust masks that are specially designed to filter out
microscopic particles.
