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.

AUTOMATIC SHUT OFF SYSTEM:
If the compressor automatically shuts off before reaching its normal cutoff pressure :

1. Shut off all tools.
2. Unplug the compressor or turn off the pressure switch.
3. Wait until the compressor cools down. (about 10 min.)
4. Replug the compressor or turn on the pressure switch to start the compressor.
5. Resume operation.

If you are using an extension cord, the compressor shuts off even after performing above procedures. In this case, the extension cord is too long or narrow. Replace the extension cord with proper length and width.

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 FILTER (AIR INTAKE):
Keep the air filter clean at all times. Do not operate the compressor with the air filter removed. The compressor does not operate at full capacity if the air filter is dirty. Before using the compressor, always check the air filter if it is clean. If not, clean the air filter or replace the filter element.

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 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.
Place the air compressor on a flat surface so that it is resting securely on the rubber feet.

OPERATING TEMPERATURE
The operating temperature of this compressor is between 0°C and 40°C (32°F and 104°F).

CAUTION

Never operate the compressor in the temperatures below 0°C (32°F) and above 40°C (104°F).

LUBRICATION

This air compressor is equipped with an Oil-Less pump designed for durability and no maintenance.

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.

Please see the chart below for the MINIMUM extension cord gauge requirements:

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.
