MAKITA MAC5200 (01) PDF Document

The specifications for the MAKITA MAC5200, along with comparable models, are listed below:

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 MAC5200 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.

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.

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.

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 INTAKE FILTER: This filter is designed to clean air coming into the compressor pump. This filter must always be clean and free from obstructions.

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.

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.

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.

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 proper level indicated on the sight glass.

Multi-Viscosity motor oils, like 10W30, 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.

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 that will accept the plug on the air compressor.

Please see the chart below as the MINIMUM requirements for 120 Volts:

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 using the MAKITA MAC5200:

1. Set the pressure switch lever to “OFF”.

2. Using the air tool or accessory, bleed the tank pressure down to zero.

3. Remove the air tool or accessory.

4. 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.

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

Note: If drain cock valve is plugged, release all air pressure. The valve can then be removed, cleaned, then reinstalled.

Daily (or before each use):

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.

Keep the air filter clean at all times. Do not operate the compressor with the air filter removed. A dirty air filter will not allow the compressor to operate at full capacity. Before you use the compressor, check the air filter to be sure it is clean. If it is dirty, check and replace the filter element.

Occasionally pull the ring on the safety valve to make sure that the safety valve operates freely. If the valve is stuck or does not operate smoothly, it must be replaced with the same type of valve. If the safety valve does not work properly, over-pressurization may occur, causing air tank rupture or an explosion.

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.
