Frequently Asked Questions - MAC3001 MAKITA

What type of oil should be used in the MAC3001 compressor?

Use a non-detergent SAE 20W (ISO 68) oil for ambient temperatures from 34°F to 79°F (1°C to 26°C). For other temperatures, refer to the table in the manual (SAE 10W for 3°F to 32°F (-16°C to 0°C), SAE 30W for above 81°F (>27°C)).

What is the oil capacity of the compressor?

The oil capacity is approximately 1 liter. Refer to the sight gauge for the optimal level (middle of the sight glass).

How often should the oil be changed?

Change the oil every 300 hours of operation or every 3 months, whichever comes first.

How do I check and adjust belt tension?

The belt should deflect approximately 1/2 inch (12.7 mm) under a load at the center. To replace it, loosen the motor bolts, slide the motor toward the pump, install the new belt, then tension it by moving the motor away.

What should I do if the compressor does not start?

First check the power supply (outlet, fuse, or circuit breaker). Make sure the pressure switch is in the "Auto" position and the drain valve is closed.

How do I drain water from the tank?

Open the drain valve located under the tank to drain condensed water. Do this daily before each use.

What is the maximum tank pressure?

The stop pressure is factory-set at 125 PSI (8.6 bar). Never exceed this pressure; the safety valve is set at this value.

Can I use an extension cord?

Yes, but choose an extension cord of sufficient gauge: for 15 A and 120 V, use AWG 14 up to 50 ft (15 m) and AWG 12 for 100 ft (30 m). Avoid excessively long extension cords.

How do I switch from automatic to continuous mode?

On the pilot unloader device, open the valve (knob unscrewed upward) for continuous mode. In automatic mode, close the valve (screwed fully downward).

What should I do if the compressor vibrates excessively?

Check that the compressor is level and that the mounting bolts are not too tight. Ensure the belts are not worn and the pulleys are aligned.

CAREFULLY READ THIS INSTRUCTION MANUAL BEFORE ATTEMPTING TO OPERATE THIS COMPRESSOR.

SAFETY PRECAUTIONS

Please familiarize yourself with the following information to prevent damage to your compressor unit and injury to the operator.

CAUTIONS

CAUTION

The air compressor motor will get hot while in operation. Never touch the discharge tubing, motor or compressor pump while in operation. The compressor

operates automatically while the power is connected and turned on.

WARNING

Compressed air from the unit may contain hazardous fumes. Air produced by this compressor is not suitable for breathing purposes. Always use a respirator when

spraying paint or chemicals, or when sandblasting. Always wear safety glasses or goggles when using compressed air.

It is not practical or possible to warn you about all the hazards associated with operating or maintaining this equipment. You must use your own good judgment.

AIR RECEIVER

Over pressurizing the air compressor could cause personal injury or material damage. To protect from over pressurizing, a factory pre-set safety valve is installed.

NEVER WELD, DRILL OR CHANGE THE AIR RECEIVER IN ANY WAY

Any replacement parts should be purchased with the same specifications as the original equipment. Please contact the authorized dealer for replacement parts or specifications.

SAFETY VALVE

This valve is factory installed to prevent over pressurizing of the air receiver. It is factory set at a specific limit for your particular model, and should never be tampered with.

Adjustment by user will automatically Void the warranty.

DO NOT REMOVE, MAKE ADJUSTMENTS TO OR SUBSTITUTE THIS VALVE!

The use of extension cords is not recommended. Plug directly into a dedicated circuit. If the use of an extension cord is unavoidable then make sure your extension cord is in good condition. When using an extension cord, be sure to use one heavy enough to carry the current your product will draw. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. Table 1 shows the correct size to use depending on cord length and nameplate amperage rating. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.

INSTALLATION

Proper care, maintenance and lubrication ensure longevity. The compressor should always be level for proper lubrication. Do not ever tighten foot bolts as excessive vibration may occur. Use only in a clean, dry, and well-ventilated area. The compressor has heat dissipation fins for proper cooling. Keep the fins and other parts that collect dust clean. Do not place rags or other materials on top of the compressor, as this obstructs cooling and can be a fire hazard.

BEFORE OPERATING THE AIR COMPRESSOR

PLEASE CHECK THE FOLLOWING CAREFULLY:

1) Check to see that nuts and bolts are all snug.
2) Check if the quantity and quality of oil is correct.
3) If the intake filters are dirty, they should be replaced or cleaned.

Compressor oil	# EAOIL10 (1 Litre)
*Compressor originally filled with SAE 20W oil (ISO 68)

Compressor oil is a non-detergent mineral oil formulated with additives to help minimize carbon build up, increase ring life and reduce oil consumption, for use at ambient temperatures of 0^ to 30^ C ( 32^ - 86^ F).

OTHER APPROVED OILS

Regular mineral oils can also be used in this compressor. Always use non-detergent oil with the following specifications:

AMBIENT TEMPERATURE AT POINT OF OPERATION	SAE VISCOSITY	ISO VISCOSITY
-16°C to 0°C (3.2°F to 32°F)	SAE 10W	ISO 32
1°C to 26°C (33.8°F to 78.8°F)	SAE 20W	ISO 68
Above 27°C (80.6°F)	SAE 30W	ISO 100

OIL CHANGES

INITIAL OIL CHANGE DUE AT 100 HOURS

CHANGE OIL EVERY 300 HRS OR 3 MONTHS, WHICHEVER COMES FIRST.

1) Remove the oil drain plug. Allow oil to drain completely.
2) Replace the oil drain plug.
3) Refill with the recommended oil to the proper level.

Before doing any maintenance or adjustments to your air compressor, the following safety precautions should be taken:

• TURN OFF AND UNPLUG POWER CORD.
• DRAIN AIR RECEIVER AND AIR LINES OF AIR PRESSURE.

CHECKING BELT TENSION

Adjust belt(s) so when pressure is applied at the center, there is approx. 1 / 2" slack (see diagram below). If the belt is installed too tight, the motor might be overloaded. This will cause the motor to overheat. If the belt is installed too loosely, it will slip and excessive wear and vibration will occur.

HOW TO INSTALL NEW BELT IF REQUIRED

1) Disconnect power supply.
2) Remove belt guard.
3) Loosen motor bolts and slide motor toward compressor head just enough to allow old belt to be removed.
4) Install proper replacement belt.
5) Slide motor away from compressor head to provide recommended tension as shown in diagram on page 5.
6) Align belt using a straight edge ruler against pulley's edge.
7) Fasten motor bolts.
8) Ensure motor and compressor pulleys are secure. Re-check alignment.
9) Re-install belt guard and reconnect power supply.
10) Belt tension should be checked after 20 hours of operation. Check tension monthly thereafter.

OPERATING YOUR AIR COMPRESSOR

ELECTRIC DRIVE WITH DUAL CONTROL

1) Check unit for any damage.
2) Check compressor oil level, fill or add if necessary.
3) Pressure switch "Off/Auto" knob should be in "Off" position.
4) Plug in power cord to proper electrical outlet.
5) Stop/Start (pressure switch) control

a) Shut-off valve on pilot unloader should be closed ("knurled" knob on top of the pilot unloader should be turned all the way down).
b) Turn pressure switch "Off/Auto" switch to "Auto". Electric motor should now start and fill air receiver(s) with compressed air until cut-out pressure is reached. Compressor should stop and remain stopped until air receiver pressure reaches the cut-in pressure. The unit will continue to cycle in this automatic operation until it is turned off.

6) Continuous run (pilot unloader) control

a) Open the shut-off valve on pilot unloader ("knurled" knob on top of the pilot unloader should be turned all the way up).
b) Turn pressure switch "Off/Auto" switch to "Auto". Electric motor should now start and fill air receiver(s) with compressed air until full pressure is reached. To engage continuous run, turn "knurled" knob down. Your compressor will idle down and continue to idle once maximum pressure is achieved. When cut-in pressure is reached, the unloader valve will de-activate and unit will compress air. The unit will continue in this automatic operation until the unit is stopped ("Off/Auto" switch turn to the "Off" position and/or electric power supply is disconnected).

7) You can switch at anytime from Stop/Start to Continuous Run and vice versa by opening or closing the valve on the pilot unloader.

ELECTRIC DRIVE

1) Check unit for any damage.
2) Check compressor oil level, fill or add oil if necessary.
3) Pressure switch "Off/Auto" switch should be in "Off" position.
4) Plug in power cord to proper electrical outlet. If compressor is not equipped with a male plug, hire an electrician to install one.
