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% of one hour is considered misuse because the air compressor is undersized for the  required air demand.

GENERAL INFORMATION

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.
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

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.

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.
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 10W 30, 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:

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.

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 3blade grounding plug and a 3slot receptacle that will accept the plug on the air compressor.
• Make sure the extension cord is in good condition.
  Please see the chart below as the MINIMUM 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 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.

OPERATING PROCEDURES
Daily Start-up Checklist

1. 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.

2. 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.

3. Turn the pressure switch lever to “ON/AUTO” and allow tank pressure to build. Motor will stop when tank pressure reaches “cut-out” pressure.

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.
   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 accessory.

9. Drain water from air tank by opening drain cock valve on bottom of tank. WATER WILL CONDENSE IN THE AIR TANK. IF NOT DRAINED, WATER WILL CORRODE AND WEAKEN THE AIR TANK CAUSING A RISK OF AIR TANK RUPTURE.
   Note:
   If drain cock valve is plugged, release all air pressure. The valve can then be removed, cleaned, then reinstalled.

10. After the water has been drained, close the drain valve.
    The air compressor can now be stored.
