Auto On(I)/Off(O) Switch
1
: Place this switch in the
"AutoOn" position to provide automatic power to the
pressure switch and "Off" to remove power at the end of
eachuse.
Pressure Switch (not shown): The pressure switch
automatically starts the motor when the air tank pressure
drops below the factory set "cut-in" pressure. It stops the
motor when the air tank pressure reaches the factory set
"cut-out"pressure.
Safety Valve
4
: If the pressure switch does not shut off the
air compressor at its "cut-out" pressure setting, the safety
valve will protect against high pressure by "popping out"
at its factory set pressure (slightly higher than the pressure
switch "cut-out" setting).
Tank Pressure Gauge
5
: The tank pressure gauge
indicates the reserve air pressure in thetank.
One-Turn Regulator
6
: Controls the air pressure available
at the quick-connect outlet. Turn regulator clockwise to
increase pressure or counterclockwise to decrease pressure.
Stop when indicator matches with desired outlet pressure.
Cooling System (not shown): This compressor contains
an advanced design cooling system. At the heart of this
cooling system is an engineered fan. It is perfectly normal
for this fan to blow air through the vent holes in large
amounts. You know that the cooling system is working
when air is beingexpelled.
Air Compressor Pump (not shown): Compresses air 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.
Drain Valve
7
: The drain valve is located at the base of
the air tank and is used to drain condensation at the end of
eachuse.
Check Valve
8
: 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.
Motor Overload Protector (not shown): The motor has
a thermal overload protector. If the motor overheats for any
reason, the overload protector will shut off the motor. The
motor must be allowed to cool down before restarting. To
restart:
1. Set the Auto On/Off switch to "Off".
2. Remove thebattery.
3. Allow the motor tocool.
4. Replace thebattery.
5. Set the Auto On/Off switch to "Auto On"position.
Quick-Connect Coupler
9
: The quick connect body
accepts industrial quick connectplugs.
How to Use Your Unit (Fig.E)
How to Stop
1. Set the Auto On/Off switch
1
to "Off".
2. Remove battery when not in use.
Before Starting

WARNING: Do not operate this unit until you read
this instruction manual for safety, operation and
maintenanceinstructions.
Before Each Start-Up
1. Remove battery. (Refer to Installing and Removing
the Battery Pack)
2. Set the Auto On/Off switch
1
to "Off".
3. Turn the regulator
6
counterclockwise to set the outlet
pressure to zero.
4. Attach hose andaccessories.

WARNING: Risk of unsafe operation. Firmly grasp
air hose in hand when installing or disconnecting
to prevent hosewhip.

WARNING: Risk of unsafe operation. Do not use
damaged or wornaccessories.
NOTE: The hose or accessory will require a quick connect
plug if the air outlet is equipped with a quick connect
body
9
.

WARNING: Risk of Bursting. 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.
NOTICE: Risk of property damage. Compressed air
from the unit may contain wa ter condensation and
oil mist. Do not spray un fil tered air at an item that
could be damaged by moisture. Some air tools and
accessories may require filtered air. Read the in struc-
tions for the air tools andaccessories.
How to Start
1. Install the battery into thetool.
2. Set the Auto On/Off switch
1
to "Auto On" and allow
tank pressure to build. Motor will stop when tank
pressure reaches "cut-out"pressure.
3. Turn regulator
6
clockwise to increase pressure and
stop when desired pressure isreached.

WARNING: Risk of unsafe operation. If any
unusual noise or vibration is noticed, stop the
compressor immediately and have it checked by
a trained servicetechnician.

WARNING: Ensure the regulator is set to a pressure
lower than the maximum operating pressure of
thetool.
The compressor is ready foruse.
