GROUNDING INSTRUCTIONS
_Riek of Electrical
Shock. In the
event of a short circuit, grounding
reduces the risk of shock by pro-
viding an escape wire for the elec-
tric current. This air compressor
must be propermy grounded.
The portable air compressor is
equipped with a cord having a
grounding wire with an appropriate
grounding plug (see following illustra-
tions).
1. The cord set and plug with this
unit contains a grounding pin.
This plug MUST be used with a
grounded outlet.
IMPORTANT: The outlet being used
must be installed and grounded in
accordance with all loca! codes and
ordinances.
Make sure the outlet being used
has the same configuration as
the grounded plug. DO NOT
USE AN ADAPTER. See illustra-
tion.
Grounding Pin
Inspect the plug and cord before
each use. Do not use if there are
signs of damage.
If these grounding instructions
are not completely understood,
or if in doubt as to whether the
compressor is properly ground-
ed, have the installation checked
by a qualified electrician.
GROUNDING CAN RESULT IN
ELECTRICAL SHOCK,
Do not modify the plug provided. If
it does not fit the avaiBable outlet,
a correct outBet should be installed
by a quaBified electrician.
Repairs to the cord set or pBug
MUST be made by a qualified emec-
trician.
A10819 10-ENG

Extension Cords
Using extension cords is not recom-
mended. The use of extension cords
will cause voltage to drop resulting
in power Ioss to the motor and over-
heating.
Instead of using an extension cord,
increase the working reach of the
air hose by attaching another length
of hose to its end. Attach additional
lengths of hose as needed.
If an extension cord must be used, be
sure it is:
® a 3-wire extension cord that has
a 3-blade grounding plug, and a
3-slot receptacle that will accept
the plug on the product
® in good condition
® no longer than 50 feet
® 12 gauge (AWG) or larger. (Wire
size increases as gauge number
decreases. 10 AWG and 8 AWG
may also be used. DO NOT USE
14 OR 16 AWG.)

Safety VaRve
Description of Operation
Become familiar with these controls
before operating the unit.
On/Auto/Off Lever: Turn this switch
to "On/Auto" to provide automatic
power to the pressure switch and
"Off" to remove power at the end of
each use.
Pressure Switch: 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: 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).
Outlet Pressure Gauge: The outlet
pressure gauge indicates the air
pressure avaiIabb at the outlet side
of the reguIator. This pressure is
controlled by the regulator and is
always Iess than or equa! to the tank
pressure.
Tank Pressure Gauge: The tank
pressure gauge indicates the reserve
air pressure in the tank.
Regulator: Controls the air pressure
shown on the outtet pressure
gauge. Pull the knob out and turn
cIockwise to increase pressure
and countercIockwise to decrease
pressure. When the desired pressure
is reached push knob in to lock in
pJace.
Drain Vamve:The drain valve is
located at the base of the air tank
and is used to drain condensation at
the end of each use.

Cooming System (not shown): This
compressor contains an advanced
design cooling system. At the heart of
this cooting system is an engineered
fan. it is perfectly norma! for this fan
to blow air through the vent hotes
in large amounts. You know that the
cooling system is working when air is
being expelled.
A10819 12-ENG

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.
Check Vatve: 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: The
motor has an automatic reset
thermai overioad protector, if the
motor overheats for any reason, the
overload protector will shut off the
motor. The motor must be allowed
to coot down before restarting. The
compressor will automatically restart
after the motor cools.

air hose from damage (such as
being stepped on or run over).
Wind them loosely around
the compressor handle. (If so
equipped)
9. Store the air compressor in a
