RULES FOR SAFE OPERATION

Be Educated:

All users must read and fully understand all information contained in this owner’s manual
before assembling, operating, or maintaining this air compressor.

Avoid Moving Parts:

When the gas engine is running:

• Never touch any moving parts.

• Keep all body parts, hair, clothing, and jewelry away from moving parts.

• Never operate the air compressor without all guards and shrouds in place.

• Never stand on the compressor.

Attachments and Accessories:

For any attachment or accessory you will be using with this compressor, the maximum
allowable recommended pressure should be clearly marked on the product or should be
clearly noted within the operations manual. Exceeding the pressure rating of these
attachments (including, but not limited to: air tools, air operated accessories, spray guns, air
hose, air hose connections, tires and other inflatables) could cause them to fly apart or
explode and could result in serious injury.

• Never exceed the maximum allowable pressure recommended by the manufacturer of any
attachment or accessory you use with this compressor.

Personal Protection:

The employer and/or user must ensure that proper eye protection is worn. Eye protection
equipment must conform to the requirements of the American National Standards Institute
ANSI Z87.1 and provide both frontal and side protection.
NOTICE!: Non-side shielded spectacles and face shields alone do not provide adequate
protection. Eye protection conforming to ANSI Z87.1 will always be marked “Z87”.
CAUTION: Additional Safety Protection will be required in some environments. For
example, the working area may include exposure to noise level which can lead to hearing
damage. The employer and user must ensure that any necessary hearing protection is
provided and used by the operator and others in the work area. Some environments will
require the use of head protection equipment. When required, the employer and user must
ensure that head protection conforming to ANSI Z89.1.

• Always wear eye protection.

•Wear proper hearing and head protection.

• Compressed air blast must never be aimed at anyone. Compressed air can cause
bodily injury and can propel loose particles and small objects at high speed.

• Keep children away from area of operation.

Transporting:

Use the handle to move the compressor. Do not drag or pull the compressor by the power
cord or air hose. Always disconnect the air compressor before transporting.

RULES FOR SAFE OPERATION (continued)

Air Tanks:

Due to condensation associated with the process of compressing air, moisture will build up
inside your compressor’s air tank. Drain tanks of moisture daily (See General Maintenance).
Failure to drain moisture from the tanks properly could lead to the formation of rust and
thinning of the steel tank.

WARNING: FAILURE TO REGULARLY DRAIN TANK MAY CAUSE TANK CORROSION AND
RISK OF TANK EXPLOSION, RESULTING IN SERIOUS INJURY. TO AVOID RISK OF TANK
FAILURE DURING USE, DRAIN TANK AFTER EACH USE OR EVERY FOUR HOURS OF
OPERATION TO PREVENT CONDENSATION BUILD-UP AND TANK CORROSION.

WARNING: DO NOT PERFORM WELDING OR REPAIR OPERATIONS ON THE AIR TANK OF
THIS COMPRESSOR. WELDING ON THE AIR COMPRESSOR TANK CAN SEVERELY IMPAIR
TANK STRENGTH AND CAUSE AN EXTREMELY HAZARDOUS CONDITION. WELDING ON
THE TANK IN ANY MANNER WILL VOID THE WARRANTY.

Ventilation:
WARNING: RISK OF FIRE OR EXPLOSION - DO NOT SPRAY FLAMMABLE LIQUID IN A

CONFINED AREA. SPRAY AREA MUST BE WELL VENTILATED. DO NOT SMOKE WHILE
SPRAYING AND DO NOT SPRAY WHERE SPARK OR FLAME IS PRESENT. KEEP
COMPRESSORS AS FAR FROM SPRAYING AREA AS POSSIBLE.

Risk of Burns:

All air compressors generate heat, even operating under normal conditions.

• To avoid serious burns, never touch the cylinder head parts or tubing during or immediately
after operation.

Safety Valve:

This compressor is equipped with a safety valve that is set to avoid over-pressurization of the
air tanks. This valve is factory pre-set at 140 PSI and will not function unless tank pressure
reaches this pressure. DO NOT ATTEMPT TO ADJUST OR ELIMINATE THIS SAFETY DEVICE.
ANY ADJUSTMENTS TO THIS VALVE COULD CAUSE SERIOUS INJURY. If this device
requires service or maintenance, see an Authorized BOSTITCH Service Center.

DUTY CYCLE:

To ensure long life of your BOSTITCH air compressor, do not operate on more than a 50% duty
cycle. If this air compressor pumps air more than 50% of one hour, then the compressor’s
capability is less than the air delivery required by the application. Always match the air
volume requirements of the attachment or accessory with the air volume delivery of the
compressor.
