GLOSSARY  
GENERAL  
INFORMATION  
CFM: Cubic feet per minute.  
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.  
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.  
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.  
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".  
Separate air transformers which  
combine the functions of air  
regulation and/or moisture and  
dirt removal should be used  
where applicable.  
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".  
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.  
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% of one hour is  
considered misuse because the  
air compressor is undersized for  
the required air demand.  
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

you, report any damages to the  
carrier and arrange for inspection  
of goods immediately.  
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  
STORAGE  
Before you store the air  
compressor, make sure you do  
the following:  
“Maintenance”.  
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.  
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.  
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.  
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.  
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.  
PRESSURE SWITCH  
UNLOADING VALVE: The  
pressure switch unloading valve  
located on the side of the  
pressure switch, is designed to  
automatically release  
ON/AUTO - OFF SWITCH: Turn  
this switch to “on” to provide  
automatic power to the pressure  
compressed air from the  
compressor head and the outlet  
tube when the air compressor  
Page 8  
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.

PROCEDURES  
SAFETY VALVE: If the pressure  
switch does not shut off the air  
compressor at its “cut-out”  
LOCATION OF THE AIR  
COMPRESSOR  
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).  
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  
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”.  
excessive moisture. Follow the  
instructions packaged with the air  
filter for proper installation.  
TANK PRESSURE GAUGE: The  
tank pressure gauge indicates  
the air pressure in the tank.  
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  
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

Initial Start Up Procedure:  
1.Open the air receiver's drain  
valve.  
2.Plug power supply cord into  
correct power source.  
3.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.  
4.Close air receiver drain valve.  
Your compressor is now ready  
for use.  
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.  
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:  
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  
· 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.

accordance with all local codes  
and ordinances. The outlet must  
have the same configuration as  
the plug. DO NOT USE AN  
ADAPTER.  
4. Open the regulator by turning  
it clockwise. Adjust the  
regulator to the correct  
pressure setting. Your  
compressor is ready for use.  
5. 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.  
Inspect the plug and cord before  
each use. Do not use if there are  
signs of damage.  
When you are finished:  
6. Set the pressure switch lever  
to “OFF”.  
7. Using the air tool or  
accessory, bleed the tank  
pressure down to zero.  
8. Remove the air tool or

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.  
MAKITA LIMITED ONE YEAR WARRANTY  
Warranty Policy  
Every Makita tool is thoroughly inspected and tested before leaving the  
factory. It is warranted to be free of defects from workmanship and materials  
for the period of ONE YEAR from the date of original purchase. Should any  
trouble develop during this one year period, return the COMPLETE tool,  
freight prepaid, to one of Makita’s Factory or Authorized Service Centers. If  
inspection shows the trouble is caused by defective workmanship or material,  
Makita will repair, (or at our option, replace), without charge.  
This warranty does not apply where:  
• repairs have been made or attempted by others;  
• repairs are required because of normal wear and tear;  
• the tool has been abused, misused or improperly maintained;  
• alterations have been made to the tool.  
IN NO EVENT SHALL MAKITA BE LIABLE FOR ANY INDIRECT,  
INCIDENTAL OR CONSEQUENTIAL DAMAGES FROM THE SALE OR USE  
OF THE PRODUCT. THIS DISCLAIMER APPLIES BOTH DURING AND  
AFTER THE TERM OF THIS WARRANTY.  
MAKITA DISCLAIMS LIABILITY FOR ANY IMPLIED WARRANTIES,  
INCLUDING IMPLIED WARRANTIES OF "MERCHANTABILITY" AND  
"FITNESS FOR A SPECIFIC PURPOSE," AFTER THE ONE YEAR TERM OF  
THIS WARRANTY.  
This Warranty gives you specific legal rights, and you may also have other  
rights which vary from state to state. Some states do not allow the exclusion  
or limitation of incidental or consequential damages, so the above limitation or  
exclusion may not apply to you. Some states do not allow limitation on how  
long an implied warranty lasts, so the above limitation may not apply to you.
