Makita MAC1200 owner manual Duty Cycle, General Information, On-Receipt, Description of Operation

GLOSSARY

CFM: Cubic feet per minute.

SCFM: Standard cubicfeet per minute; a unit of measure of air delivery.

PSIG: Pounds per square inch gauge; a unit of measure of pressure.

ASME: American Society of Mechanical Engineers; made, tested, inspected and registered to meet the standards of

ASME.

California Code: Units comply with California Code462 (L) (Z)/(M) (2). Specification/model label is on the side of the tank on units that comply with California Code.

Cut-In Pressure: While the motor is off, air tank pressure drops as you continue t o use your accessory

or air tool. When the tank pressure drops to a certain level the motor will restart automatically.* The pressure a t which the motor automatically re-starts is called "cut-in pressure."

Cut-Out Pressure: When you turn on your air compressor and it begins t o run, air pressure in the air tank begins t o build. It builds t o a certain high pressure before the motor automati- cally shuts off - protecting your air tank from pressure higher than its capacity. The high pressure a t which the motor shuts off is called "cut-out pressure."

U.L. Listed: Pr0ductswiththeU.L markarelisted by Underwrit- ers Laboratories, Inc. (U.L.). Samples of these products have been evaluated by U.L. and meet the applicable U.L standards for safety.

DUTY CYCLE

All Makita manufactured air compressors should be operated on not morethan 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. Maximum compressor pumping time per hour is 30 minutes.

GENERAL INFORMATION

This air compressor requires no oil. Now you can enjoy all the benefits of having an air compressor without ever having to

purchase, add or change oil.-

I

Your air compressor can be used for operating paint spray guns, air tools, caulking guns, grease guns, air brushy, sandblaster, inflating tires and plastic toys, 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

DAMAGE: Each air compressor outfit is carefully tested and checked before shipment. With improper handling, dahage may
result in transit and cause problems in compressor operation.	, ! L

Immediately upon arrival, check equipment for both concealed and visible damages t o avoid expenses being incurred t o correct such problems. This should be done regardless of any visible signs of damage t o the shipping container. If this product was shipped directly t o you, report any damages to carrier and arrange for inspection of goods immediately.

DESCRIPTION OF OPERATION

Drainvalve: Thedrainvalveis locatedatthe baseoftheair tank and is used to drain condensation at the end of each use.

MotorThermal Overload Protector: The electric motor has an automatic thermal overload protector. If the motor overheatsfor any reason,thethermaloverload protectorwillshutoff themotor. The motor must be allowed to cool before restarting.

ONlAUTO - OFF Switch: Turn this switch ON to provide automatic power to the pressure switch and OFF to remove power at the end of each use.

Air Intake Filter: This filter is designed to clean air coming into the pump. This filter must alwavs be clean and free from obstructions. See "Maintenance".

Air Compressor Pump: To compress air, the piston moves Up and down in the cylinder. On the downstroke, air is drawn in through the air intake valve. The exhaust valve remains closed. On the upstrokeofthe piston,airiscompressed. Theintakevalve closes and compressed air is forced out through the exhaust valve,throughtheoutlettube,throughthecheckvalveand intothe air tank. Working air is not available until the compressor has raised the airtank pressure above that required at the air outlet.

Checkvalve: 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 insidethe airtank.
