or air tool. When the tank pressure drops t o a certain level the
motor will restart automatically.* The pressure a t which the
motor automatically re-starts is called "cut-in pressure."
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 Code 462 (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
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."

DUTY 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 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
applica ble.

ON-RECEIPT
DAMAGE: Each air compressor outfit is carefully tested and checked before shipment. With improper handling, dahage may
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.

DESCRIPTION OF OPERATION
Drainvalve: Thedrainvalveis locatedatthe baseoftheair 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 overheats for
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, through theoutlettube, through thecheckvalve and into the
air tank. Working air
i s
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 inside the airtank.
