Astro Pneumatic 29 Gallon Belt Driven Air Compressor 68127 - Manual (Page 8)

ELECTRICAL
EXTENSION CORDS
Use only 3-wire extension cords that have 3-prong
grounding plugs and 3-pole receptacles that accept the
air compressor’s plug. When using the air compressor at
a considerable distance from the power source, use an
extension cord heavy enough to carry the current that the
compressor will draw. An undersized extension cord will
cause a drop in line voltage, resulting in a loss of power
and causing the motor to overheat. Use the chart pro­
vided below to determine the minimum wire size required
in an extension cord. Only round jacketed cords listed by
Underwriter’s Laboratories (UL) should be used.

NOTE; AWG = American Wire Gauge
When working with the air compressor outdoors, use an
extension cord that is designed for outside use. This is
indicated by the letters “WA” on the cord’s jacket.
Before using an extension cord, inspect it for loose or
exposed wires and cut or worn insulation.
¿k WARNING:
Keep the extension cord clear of the working area.
Position the cord so that it will not get caught on lumber,
tools, or other obstructions while you are working with
a power tool. Failure to do so can result in serious per­
sonal injury.
Mk WARNING:
Check extension cords before each use. If damaged,
replace immediately. Never use air compressor with a
damaged cord since touching the damaged area could
cause electrical shock resulting in serious injury.
NOTE: Use longer air hoses instead of long extension
cords. Your air compressor will run better and last longer.
ELECTRICAL CONNECTION
This air compressor is powered by a precision built
electric motor. It should be connected to a power sup­
ply that is 120 volts, 60 Hz, AC only (normal household
current). Do not operate this tool on direct current (DC).
A substantial voltage drop will cause a loss of power and
the motor will overheat. If the air compressor does not
operate when plugged into an outlet, double check the
power supply.
SPEED AND WIRING
The no-load speed of the electric motor varies by model and
specification. The motor speed is not constant and decreases
under a load or with lower voltage. For voltage, the wiring
in a shop is as important as the motor’s horsepower rating.
A line intended only for lights cannot properly carry a power
tool motor. Wire that is heavy enough for a short distance will
be too light for a greater distance. A line that can support one
power tool may not be able to support two or three tools.
GROUNDING INSTRUCTIONS
This product must be grounded. In the event of an electrical
short circuit, grounding reduces the risk of electric shock
by providing an escape wire for the electric current. This
air compressor is equipped with an electric cord having an
equipment-grounding conductor and a grounding plug. The
plug must be plugged into a matching outlet that is properly
installed and grounded in accordance with all local codes and
ordinances.
Do not modify the plug provided. If it will not fit the outlet,
have the proper outlet installed by a qualified electrician.
WARNING:
Improper connection of the equipment-grounding
conductor can result in a risk of electric shock.
The conductor with insulation having an outer surface that
is green with or without yellow stripes is the equipment­
grounding conductor. If repair or replacement of the electric
cord or plug is necessary, do not connect the equipment­
grounding conductor to a live terminal.
Check with a qualified electrician or service personnel if the
grounding instructions are not completely understood, or if in
doubt as to whether the tool is properly grounded.
Repiiir or replace ^ d^mi^g^d or v\/orn cord ^nnm^diately.
This product is for use on a nominal 120-V circuit and has
a grounding plug similar to the plug illustrated in Figure 1.
Only connect the product to an outlet having the same con­
figuration as the plug. Do not use an adapter with this product.
Never use an electrical adaptor with this grounded plug.
