•	 It	is	normal	for	electrical	contacts	within	the	
motor and pressure switch to spark.
•	 If	 electrical	sparks	from	compressor	come	
into contact with flammable vapors, they
may ignite, causing fire or explosion.
•	 Restricting	any	of	the	compressor	ventilation	
openings will cause serious overheating
and could cause fire.
•	 Unattended	operation	of	this	product	could	
result	in	personal	injury	or	property	damage.	
To reduce the risk of fire, do not allow the
compressor to operate unattended.
DANGER: RIsk To BREATHING (AspHyxIATIoN)
WhAT cAn hAppen
•	 The	 compressed	 air	 directly	 from	 your	
compressor is not safe for breathing. The
air stream may contain carbon monoxide,
toxic vapors, or solid particles from the air
tank. Breathing these contaminants can
cause	serious	injury	or	death.
•	 Exposure	 to	 chemicals	 in	 dust	 created	 by	
power sanding, sawing, grinding, drilling,
and other construction activities may be
harmful.
•	 Sprayed	 materials	 such	 as	 paint,	 paint	
solvents, paint remover, insecticides, weed
killers, may contain harmful vapors and
poisons.
WARNING: RIsk of BuRsTING
Air Tank: On February 26, 2002, the U.S. Consumer Product Safety Commission published
Release # 02-108 concerning air compressor tank safety:
Air compressor receiver tanks do not have an infinite life. Tank life is dependent upon several
factors, some of which include operating conditions, ambient conditions, proper installations,
field modifications, and the level of maintenance. The exact effect of these factors on air
receiver life is difficult to predict.
If proper maintenance procedures are not followed, internal corrosion to the inner wall of the
air receiver tank can cause the air tank to unexpectedly rupture allowing pressurized air to
suddenly and forcefully escape, posing risk of injury to consumers.
Your compressor air tank must be removed from service by the end of the year shown on your
tank warning label.
The following conditions could lead to a weakening of the air tank, and result in a violent air
tank explosion:
WhAT cAn hAppen
•	 Failure	 to	 properly	 drain	 condensed	 water	
from air tank, causing rust and thinning of
the steel air tank.
•	 Modifications	or	attempted	repairs	to	the	air	
tank.
•	 Unauthorized	 modifications	 to	 the	 safety	
valve or any other components which
control air tank pressure.

INSTALLATION
How To Set Up Your Unit
LocATion of The Air compressor
•	 Locate	the	air	compressor	in	a	clean,	dry	and	well	ventilated	area.	
	 •	 The	air	compressor	should	be	located	at	least	12"	(30.5	cm)	away	from	the	wall	or	other	
obstructions that will interfere with the flow of air.
	 •	 The	 air	 compressor	 pump	 and	 shroud	 are	 designed	 to	 allow	 for	 proper	 cooling.	 The	
ventilation openings on the compressor are necessary to maintain proper operating
temperature. Do not place rags or other containers on or near these openings.
Grounding Instructions (Fig. 1)
WARNING:	Risk	of	Electrical	Shock.	In	the	event	of	a	short	circuit,	grounding	reduces	the	
risk of shock by providing an escape wire for the electric current. This air compressor must be
properly grounded.
The portable air compressor is equipped with a cord having a grounding wire with an
appropriate	grounding	plug	(A).	
	 1.	The	cord	set	and	plug	(A)	with	this	unit	contains	a	grounding	pin	(B).	This	plug	MUST	be	
used	with	a	grounded	outlet	(C).	
imporTAnT: The outlet being used must be installed and grounded in accordance with all
local codes and ordinances.
	 2.	Make	 sure	 the	 outlet	 being	 used	 has	 the	 same	 configuration	 as	 the	 grounded	 plug.	
DO NOT USE AN ADAPTER. See figure 1.
	 3.	Inspect	the	plug	and	cord	before	each	use.	Do	not	use	if	there	are	signs	of	damage.
4. If these grounding instructions are not completely understood, or if in doubt as to whether
the compressor is properly grounded, have the installation checked by a qualified electrician.
DANGER: Risk	of	Electrical	Shock.	IMPROPER	GROUNDING	CAN	RESULT	IN	ELECTRICAL	
SHOCK.
	
•		 D o	 not	 modify	 the	 plug	 provided.	 If	 it	 does	 not	 fit	 the	 available	 outlet,	 a	 correct	 outlet	
should be installed by a qualified electrician.
	
•		 R epairs	to	the	cord	set	or	plug	MUST	be	made	by	a	qualified	electrician.
•	 Follow	 the	 equipment	 manufacturers	
recommendation and never exceed the
maximum allowable pressure rating of
attachments.	 Never	 use	 compressor	 to	
inflate	 small	 low	 pressure	 objects	 such	 as	
children's toys, footballs, basketballs, etc.
•	 Use	a	tire	pressure	gauge	to	check	the	tires	
pressure before each use and while inflating
tires; see the tire sidewall for the correct tire
pressure.
noTe:	Air	tanks,	compressors	and	similar	
equipment used to inflate tires can fill
small	 tires	 very	 rapidly.	 Adjust	 pressure	
regulator on air supply to no more than
the	 rating	 of	 the	 tire	 pressure.	 Add	 air	 in	
small increments and frequently use the tire
gauge to prevent over inflation.
WARNING: RIsk of ElEcTRIcAl sHock
