HAZARD
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 HOW TO PREVENT IT
• Failure to properly drain condensed
water from air tank, causing rust
and thinning of the steel air tank.
• Drain air tank daily or after each use.
If air tank develops a leak, replace
it immediately with a new air tank
or replace the entire compressor.
• Modifications or attempted
repairs to the air tank. • Never drill into, weld, or make any modifications to the air tank or its
attachments. Never attempt to
repair a damaged or leaking air
tank. Replace with a new air tank.
• Unauthorized modifications
to the safety valve or any
other components which
control air tank pressure.
• The air tank is designed to withstand
specific operating pressures.
Never make adjustments or
parts substitutions to alter the
factory set operating pressures.
Attachments & accessories:
• Exceeding the pressure rat-
ing of air tools, spray guns, air
operated accessories, tires,
and other inflatables can cause
them to explode or fly apart, and
could result in serious injury.
• 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.

5- ENG
Tires:
• Over inflation of tires could result in
serious injury and property damage. • 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.

MAINTENANCE
To avoid personal injury, always shut off and unplug the compressor and relieve all
air pressure from the system before performing any service on the air compressor.
Regular maintenance will ensure trouble free operation. Your electric powered air
compressor represents high quality engineering and construction; however, even
high quality machinery requires periodic maintenance. The items listed below
should be inspected on a regular basis.
DRAINING THE TANK
Condensation will accumulate in the tank. To pre-
vent corrosion of the tank from the inside, this moisture must be
drained at the end of every workday. Be sure to wear protective
eyewear. Relieve the air pressure in the system and open the
drain valve on the bottom of the tank and tilt tank to drain.
NOTE: In cold climates, drain the tank after each use to reduce problems with
freezing of water condensation.
CHECKING THE RELIEF VALVE
Pull the relief valve daily to ensure that it is operating properly and to clear the valve
of any possible obstructions. Check that all connections are tight. A small leak in
any of the hoses, transfer tubes, or pipe connections will substantially reduce the
performance of your air compressor.
TESTING FOR LEAKS
If you suspect a leak, spray a small amount of soapy water around the area of the
suspected leak with a spray bottle. If bubbles appear, repair or replace the faulty
component. Do not overtighten any connections.
STORAGE
