away from moving parts. Loose clothes, jewelry, or long
hair can be caught in moving parts.
AIR COMPRESSOR USE AND CARE
For outdoor use only.
Do not exceed the pressure rating of any component
in the system.
Protect material lines and air lines from damage or
puncture. Keep hose away from sharp objects, chemical
spills, oil, solvents, and wet floors.
Check hoses for weak or worn condition before each
use, making certain all connections are secure. Do not
use if defect is found. Purchase a new hose or notify a
qualified service center for examination or repair.
Release all pressures within the system slowly. Dust
and debris may be harmful.
Store idle air compressors out of the reach of children
and other untrained persons. Air compressors are dan-
gerous in the hands of untrained users.
Maintain air compressors with care. Follow mainte-
nance instructions. Properly maintained products are
easier to control.
Check for misalignment or binding of moving parts,
breakage of parts, and any other condition that may
affect the product’s operation. If damaged, have the
air compressor serviced before using. Many accidents
are caused by poorly maintained products.
Keep the exterior of the air compressor dry, clean, and
free from oil and grease. Always use a clean cloth when
cleaning. Never use brake fluids, gasoline, petroleumbased products, or any strong solvents to clean the unit.
Following this rule will reduce the risk of deterioration of
the enclosure plastic.
Keep the engine free of grass, leaves, or grease to
reduce the chance of a fire hazard.
Keep guards in place and in working order. Never oper-
ate the tool with any guard or cover removed. Make sure
all guards are operating properly before each use.
Do not operate the engine in a confined space where
dangerous carbon monoxide fumes can collect. Carbon
monoxide, a colorless, odorless, and extremely dangerous gas, can cause unconsciousness or death.

OPERATION
DANGER:
Carbon Monoxide. Using a gas-powered air
compressor indoors CAN KILL YOU IN MINUTES.
Engine exhaust contains high levels of carbon
monoxide (CO), a poisonous gas you cannot see
or smell. If you can smell the engine exhaust, you
are breathing CO. But even if you cannot smell the
exhaust, you could be breathing CO.
Never use a gas-powered air compressor
inside homes, garages, crawlspaces, or other
partly enclosed areas. Deadly levels of carbon
monoxide can build up in these areas. Using a
fan or opening windows and doors does NOT
supply enough fresh air.
ONLY use gas-powered air compressors
outdoors and far away from open windows,
doors, and vents. These openings can pull in
engine exhaust.
Even when you use a gas-powered air compressor
correctly, CO may leak into the home. ALWAYS use
a battery-powered or battery-backup CO alarm in
the home.
If you start to feel sick, dizzy, or weak after the air
compressor has been running, move to fresh air
RIGHT AWAY. See a doctor. You could have carbon
monoxide poisoning.
WARNING:
Never direct a jet of compressed air toward people
or animals. Take care not to blow dust and dirt
towards yourself or others. Following this rule will
reduce the risk of serious injury.
WARNING:
Do not attach any tools to the open end of the hose
until start-up has been completed.
NOTICE:
Do not use in an environment that is dusty or
otherwise contaminated. Using the air compressor
in this type of environment may cause damage to
the unit.

WARNING:
RISK OF BURSTING. All compressed air
tanks have a limited lifespan. The lifespan can
be affected by a number of factors, including
operating conditions of the air compressor, proper
maintenance of the tank, and unauthorized repairs
and modifications. Since deterioration of the tank
can occur internally with no outward signs, the
air tank(s) on this compressor MUST be removed
from service by the end of the year shown on the
data label.
Tank life may be extended beyond this date by
having a certified tank inspection performed
before this date, and every 5 years following this
date, for as long as the tank is in use. Use of the
air compressor after this date without passing the
certified inspection increases the risk of an air tank
rupture, which could result in serious personal
injury.
CHECKING THE SAFETY VALVES
