Glossary

MPa (megapascal): Metric pressure measurement. 1 megapascal equals to 10 bar.

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".

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 305 mm 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.

WARNING: Risk of Falling

WHAT CAN HAPPEN

The air compressor can fall from a table, workbench, or roof causing damage to the compressor and could result in serious injury or death to the operator.

HOW TO PREVENT IT

Always operate compressor in a stable secure position to prevent accidental movement of the compressor. Never operate compressor on a roof or other elevated position. Use additional air hose to reach high locations.

Operating temperature

The operating temperature of this compressor is between 0^ C and 40^ C.

CAUTION: Never operate the compressor in the temperatures below 0°C and above 40°C.

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.

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 30.5 m 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.

Battery protection system

This compressor is equipped with a battery protection system. This system automatically cuts off power to the motor to extend compressor and battery life. The compressor will automatically stop during operation if the compressor/battery is placed under one of the following conditions:

Overloaded

The compressor/battery is operated in a manner that causes it to draw an abnormally high current. In this situation, turn the compressor off and stop the application that caused the compressor to become overloaded.

Then turn the compressor on to restart.

If the compressor does not start, the battery is overheated. In this situation, let the battery cool before turning the compressor on again.

Low battery voltage

The remaining battery capacity is too low and the compressor will not operate. If you turn the tool on, the motor runs again but stops soon. In this situation, remove and recharge the battery cartridge.

Protections against other causes

Protection system is also designed for other causes that could damage the compressor and allows the tool to stop automatically. Take all the following steps to clear the causes, when the compressor has been brought to a temporary halt or stop in operation.

1. Turn the compressor off, and then turn it on again to restart.
2. Charge the battery or replace it/them with recharged battery.
3. Let the compressor and battery cool down.

If no improvement can be found by restoring protection system, then contact your local Makita Service Center.

NOTE: Depending on the conditions of use and the ambient temperature, the indication may differ slightly from the actual capacity.

NOTE: The rst (far left) indicator lamp will blink when the battery protection system works.

CAUTION: Always switch off the tool before installing or removing of the battery cartridge.

CAUTION: Hold the tool and the battery cartridge firmly when installing or removing battery cartridge. Failure to hold the tool and the battery

cartridge rmly may cause them to slip o your hands and result in damage to the tool and battery cartridge and a personal injury.

▶ Fig.2: 1. Red indicator 2. Button 3. Battery cartridge

To remove the battery cartridge, slide it from the tool while sliding the button on the front of the cartridge.

To install the battery cartridge, align the tongue on the battery cartridge with the groove in the housing and it into place. Insert it all the way until it locks in with a little click. If you can see the red indicator shown in the gure, it is not locked completely.

CAUTION: Always install the battery cartridge fully until the red indicator cannot be seen. If not, it may accidentally fall out of the tool, causing injury you or someone around you.

CAUTION: Do not install the battery cartridge forcibly. If the cartridge does not slide in easily, it not being inserted correctly.

WARNING: Risk of Noise

- Wear hearing protection to protect your ears against exhaust noise and noise during 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.

CAUTION: When carrying the tool, turn off (0) the On/Auto-Off switch.

Air filter (Air intake):

Keep the air liter clean at all times. Do not operate the compressor with the air liter removed. The compressor does not operate at full capacity if the air liter is dirty. Before using the compressor, always check the air liter if it is clean. If not, clean the air liter or replace the 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:

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.

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.

Air outlet:

For regular pressure pneumatic tool, use outlet max pressure; 0.93 MPa (9.3 bar).

When using a quick coupler in the market, install it to the air outlet using the two wrenches as shown in the figure.

▶ Fig.4: 1. Air outlet 2. Quick coupler 3. Wrench

NOTE: If the quick coupler does not have any air sealing method, we recommend applying an adequate measure such as a sealing tape.
