MAKITA MAC700 (01) PDF Document

The specification chart for the MAKITA MAC700 (and related models) is as follows:

The minimum circuit requirement is 15 AMPS. A circuit breaker is preferred. Use only a fuse or circuit breaker that is the same rating as the branch circuit the air compressor is operated on. If the air compressor is connected to a circuit protected by fuses, use time delay fuses.

The MAKITA MAC700 is 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.

Before you store the air compressor, make sure you do the following:

1) Review the Maintenance and Operating Procedures sections and perform maintenance 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.

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 the pressure switch to the “off” position and wait for the unit to cool before pushing the reset button and restarting the 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. If humidity is high, an air filter can be installed on the air outlet adapter to remove excessive moisture.

Yes. 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. Compressor oil is provided; on a level surface, please fill the crankcase to the proper level indicated on the sight glass.

Note: Compressors are shipped without oil. A small amount of oil may be present in the pump upon receipt due to factory testing.

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.

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. Please see the chart below for MINIMUM requirements:

Use only metal pipe for air distribution lines. Plastic or PVC pipe is not designed for use with compressed air and can burst. If a pipeline is necessary, use pipe that is the same size, or larger than, the air tank outlet. If piping is over 100 feet long, use the next larger size.

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. Do not modify the plug that has been provided.

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.

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. Warning: 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.

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

Daily:

1) Drain water from the air tank, any moisture separators or transformers.

2) Check for any unusual noise and/or vibration.

3) Manually check all safety valves to make sure they are operating properly.

4) Inspect air filter, replace if necessary.

5) Inspect air lines and fittings for leaks; correct as necessary.

Each year of operation or if a problem is suspected:

1) Check condition of air compressor pump intake and exhaust valves.

2) Check condition of check valve. Replace if damaged or worn out.

Filling with oil:

1) Remove the oil filler plug.

2) Slowly pour the proper oil into the pump crankcase.

3) Always keep oil level in the middle of the sight glass.

Changing the oil (Every 300 hours or 3 months, whichever comes first):

1) Remove the oil drain plug. Allow oil to drain completely.

2) Replace the oil drain plug (The use of a sealing compound or Teflon tape to avoid leakage is recommended).

3) Refill with the recommended oil to the proper level.

1) Release all air pressure from air tank and unplug outfit.

2) Remove shroud.

3) Loosen the top and bottom nut of the outlet tube and remove.

4) Remove the pressure release tube and fitting.

5) Unscrew the check valve (turn counterclockwise) using a socket wrench.

6) Check that the valve disc moves freely inside the check valve and that the spring holds the disc in the upper, closed position. The check valve may be cleaned with a suitable solvent.

7) Apply sealant to the check valve threads. Reinstall the check valve (turn clockwise).

8) Replace the pressure release tube and fitting.

9) Replace the outlet tube and tighten top and bottom nuts.

10) Replace the shroud.

The motor has a manual reset thermal overload protector switch. If the motor overheats for any reason, the overload protector will shut off the motor. The motor must be allowed to cool down before resetting the overload switch and restarting. If the overload protector shuts the motor off frequently, check for a possible voltage problem.

Prior to attempting any repairs, unplug the compressor and bleed off tank air pressure.
