SECTION 1: SAFETY
For Your Own Safety Read Instruction Manual
Before Operating This Equipment
The purpose of safety symbols is to attract your attention to possible hazardous conditions. This manual uses a series of symbols and signal words which
are intended to convey the level of importance of the safety messages. The
progression of symbols is described below. Remember that safety messages by
themselves do not eliminate danger and are not a substitute for proper accident
prevention measures.
Indicates an imminently hazardous situation which, if
not avoided, WILL result in death or serious injury.
Indicates a potentially hazardous situation which, if
not avoided, COULD result in death or serious injury.
Indicates a potentially hazardous situation which, if
not avoided, MAY result in minor or moderate injury.
It may also be used to alert against unsafe practices.
NOTICE
This symbol is used to alert the user to useful information about proper operation of the equipment.
Safety Instructions for Pneumatic Tools
1. READ THROUGH THE ENTIRE
MANUAL BEFORE STARTING
MACHINERY. Machinery presents
serious injury hazards to untrained
users.
2. ALWAYS USE ANSI APPROVED
SAFETY GLASSES WHEN
OPERATING MACHINERY. Everyday
eyeglasses only have impact resistant
lenses, they are NOT safety glasses.
3. ALWAYS WEAR AN ANSI
APPROVED RESPIRATOR WHEN
OPERATING MACHINERY THAT
PRODUCES DUST. Wood dust is a
carcinogen and can cause cancer and
severe respiratory illnesses.
Model G0471 3 HP Air Compressor
4. ALWAY S USE HEAR ING
PROTECTION WHEN OPERATING
MACHINERY. Machinery noise can
cause permanent hearing damage.
5. WEAR PROPER APPAREL. DO NOT
wear loose clothing, gloves, neckties,
rings, or jewelry which may get caught
in moving parts. Wear protective hair
covering to contain long hair and
wear non-slip footwear.
6. NEVER OPERATE MACHINERY
WHEN TIRED, OR UNDER THE
INFLUENCE OF DRUGS OR
ALCOHOL. Be mentally alert at all
times when running machinery.
-3-
7. KEEP CHILDREN AND VISITORS
AWAY. Keep all children and visitors
a safe distance from the work area.
8. MAKE WORKSHOP CHILD PROOF.
Use padlocks, master switches, and
remove start switch keys. Shut off air
supply before leaving shop.
9. NEVER LEAVE UNATTENDED
TOOL CONNECTED TO AIR. DO
NOT leave before relieving the tool
of air pressure and disconnecting it
from the air hose.
10. DO NOT USE IN DANGEROUS
ENVIRONMENTS. DO NOT use in
damp, wet locations, or where flammable or noxious fumes may exist.
11. KEEP WORK AREA CLEAN AND
WELL LIT. Clutter and dark shad-
ows may cause accidents.
12. USE A GROUNDED EXTENSION
CORD RATED FOR THE MACHINE
AMPERAGE. Undersized cords
overheat and lose power. Replace
extension cords if they become damaged. DO NOT use extension cords
for 220V machinery.
13. ONLY ALLOW TRAINED AND
PROPERLY SUPERVISED PERSONNEL TO OPERATE MACHINERY. Make sure operation instruc-
tions are safe and understood.
14. MAKE SURE GUARDS ARE IN
PLACE AND WORK CORRECTLY
BEFORE USING MACHINERY.
15. CHECK FOR DAMAGED PARTS
BEFORE USING MACHINERY.
Check for binding and alignment of
parts, broken parts, part mounting,
loose bolts, and any other conditions
that may affect machine operation.
Repair or replace damaged parts.
16. REMOVE ADJUSTING KEYS AND
WRENCHES. Make a habit of check-
ing for keys and adjusting wrenches
before turning machinery ON.
17. REDUCE THE RISK OF
UNINTENTIONAL FIRING. DO NOT
carry tool with hand on trigger and
disconnect from air when not in use.
18. USE PROPER AIR HOSE for the
tool. Make sure your air hose is in
good condition and is long enough to
reach your work without stretching.
19. DO NOT FORCE MACHINERY. Work
at the speed for which the machine
or accessory was designed.
20. DO NOT OVERREACH. Keep proper footing and balance at all times.
21. SECURE WORKPIECE. Use clamps
or a vise to hold the workpiece when
practical. A secured workpiece protects your hands and frees both
hands to operate the tool.
22. USE SUGGESTED ACCESSORIES.
Refer to the instruction manual for
recommended accessories. The use
of improper accessories may cause
risk of injury.
23. MAINTAIN MACHINERY WITH
CARE. Keep tools lubricated and
clean for best and safest performance. Follow instructions for lubricating and changing accessories.
24. ALWAYS DISCONNECT FROM
POWER SOURC E BEFORE
SERVICING MACHINERY. Make
sure switch is in OFF position before
reconnecting.
25. DISCONNECT PNEUMATIC TOOLS
FROM COMPRESSOR. Always dis-
connect tools before servicing or
changing accessories.
26. BE AWARE THAT CERTAIN
WOODS MAY CAUSE ALLERGIC
REACTIONS IN PEOPLE AND
ANIMALS, ESPECIALLY WHEN
EXPOSED TO FINE DUST. Make
sure you know what type of wood
dust you will be exposed to and
always wear an approved respirator.

Additional Safety Instructions
for Air Compressors
1. AIR NOZZLE. Never aim an air noz-
zle directly at yourself or others.
Compressed air can break the skin,
or enter the bloodstream through soft
tissue or a cut, and cause a stroke or
death.
2. AIR COMPRESSOR STORAGE.
DO NOT store the compressor while
plugged into power. If a leak develops, the compressor may run continuously, causing overheating and
possibly a fire.
3. UNATTENDED TOOLS. DO NOT
leave before relieving the tool of air
pressure and disconnecting it from
the air hose.
4. AVOID BURNS. DO NOT touch the
motor or the air supply pipe, they will
become hot during operation.
5. AIR HOSE. Make sure your air hose
has a PSI rating exceeding the maximum PSI of your compressor, is in
good condition, and is long enough
to reach your work without stretching.
Make sure the air lines and power
cord do not come in contact with
sharp or abrasive objects.
6. COMPRESSED AIR USE. Do not
use the compressor for filling breathing or diving tanks. Compressed air
from this compressor cannot be used
for pharmaceutical, food or health
applications.
7. PLASTIC (PVC) PIPE. DO NOT use
plastic pipe for high pressure air
lines. It could shatter, resulting in
serious injury.
8. TANK CORROSION. Drain the tank
after each use to prevent corrosion
and possible tank rupture. Inspect
the tank for unsafe conditions such
as rust, pin holes and cracks. NEVER
weld or drill holes in an air tank.
9. SAFETY VALVE OR PRESSURE
SWITCHES. NEVER adjust safety
valve or pressure switch to allow the
compressor to build higher PSI than
rated. Keep safety valve free from
paint and other accumulations to provide safety against over-pressure.
10. CHECK OIL LEVEL. Use the sight
gauge on the bottom of the crankcase to make sure the oil level is at
the proper height.
There is danger associated with the
use of air compressors. Accidents are
frequently caused by lack of familiarity or failure to pay attention. Use
this air compressor with respect and
caution to lessen the possibility of
operator injury. If normal safety precautions are overlooked or ignored,
serious personal injury may occur.
Model G0471 3 HP Air Compressor
No list of safety guidelines can be
complete. Every environment is different. Always consider safety first,
as it applies to your individual working conditions. Use this and other
machinery with caution and respect.
Failure to do so could result in serious personal injury, damage to equipment or poor work results.

SECTION 2: CIRCUIT
REQUIREMENTS
220V Operation
Serious personal injury could occur
if you connect the machine to the
power source before you have completed the set up process. DO NOT
connect the machine to the power
source until instructed to do so.

The 3 HP motor on the Model G0471 will
draw the following amps:
G0471 Motor Draw ......................18 Amps
Circuit Requirements
Only connect your machine to a circuit that meets the requirements below.
Always check to see if the wires and
circuit breaker in your circuit are capable
of handling the amperage draw from your
machine, as well as any other machines
that could be operating on the same circuit. If you are unsure, consult a qualified
electrician.
Plug/Receptacle Type

Grounding
In the event of an electrical short, grounding reduces the risk of electric shock. The
grounding wire in the power cord must
be properly connected to the grounding
prong on the plug; likewise, the outlet
must be properly installed and grounded.
All electrical connections must be made
in accordance with local codes and ordinances.
El e ctro c utio n o r
fire could result if
this machine is not
grounded correctly or
if your electrical configuration does not
comply with local and
state codes. Ensure
compliance by checking with a qualified
electrician!
Extension Cords
We do not recommend the use of extension cords on 220V equipment. Instead,
arrange the placement of your equipment
and the installed wiring to eliminate the
need for extension cords.
If you find it absolutely necessary to
use an extension cord at 220V with your
machine, check with a qualified electrician
for the correct sizing, type, and maximum
possible length for your needs.
