GLOSSARY
CFM: Cubic feet per minute.
SCFM: Standard cubic feet per minute; a unit of measure
of air delivery.
PSIG: Poundsperlquare 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 Code 462 (L)
(2)/(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 to use your accessory
DUTY
or air tool. When the tank pressure drops to a certain level*
the motor will restart automatically. The pressure at which
the motor automatically re-starts is called "cut-in pressure."
Cut Out Pressure: When you turn on your air compressor
and 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 pres¬
sure higher than its capacity. The pressure at which the motor
shuts off is called "cut-out pressure."
U.L. Listed: Products with the U.L. mark are listed by Under¬
writers Laboratories, Inc. (U.L.). Samples of these products
have been evaluated by U.L. and meet the applicable U.L.
standards for safety.
*See Specification Chart on front page.
CYCLE
All Makita manufactured air compressors should 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. 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.
Your air compressor can be used for operating paint spray guns, air tools, caulking guns, grease guns, air brushes, 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 INSPECTION -
DAMAGE: Each air compressor outfit is carefully tested and checked before shipment. With improper handling, damage may
result in transit and cause problems in 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 carrier and arrange for inspection of goods immediately
DESCRIPTION OF OPERATION
Drain Valve:
The drain valve is located at the base of the air
tank and is used to drain condensation at the end of each use.
Motor
Thermal Overload Protector:
The electric motor has
an automatic thermal overload protector. If the motor over¬
heats for any reason, the thermal overload protector will shut
off the motor. The motor must be allowed to cool before
restarting.
ON/AUTO - 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 always 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 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. Working 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.
