SAFETY INSTRUCTIONS
EYE PROTECTION which conforms to ANSI specifications and provides protection against
flying particles both from the FRONT and SIDE should ALWAYS be worn by the operator and
others in the work area when connecting to air supply, loading, operating or servicing this
tool. Eye protection is required to guard against flying fasteners and debris, which could
cause severe eye injury.
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. NOTE: Non-side shielded
spectacles and face shields alone do not provide adequate protection.
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 is used.
AIR SUPPLY AND CONNECTIONS
Do not use oxygen, combustible gases, or bottled gases as a power source for this tool as
tool may explode, possibly causing injury.
Do not use supply sources which can potentially exceed 200 P.S.I.G. (14 kg/cm
2
) as tool
may burst, possibly causing injury.
The connector on the tool must not hold pressure when air supply is disconnected. If a
wrong fitting is used, the tool can remain charged with air after disconnecting and thus will
be able to drive a fastener even after the air line is disconnected possibly causing injury.
Do not pull trigger or depress contact arm while connected to the air supply as the tool may
cycle, possibly causing injury.
Always disconnect air supply: 1.) Before making adjustments; 2.) When servicing the tool;
3.) When clearing a jam; 4.) When tool is not in use; 5.) When moving to a different work
area, as accidental actuation may occur, possibly causing injury.
LOADING TOOL
When loading tool: 1.) Never place a hand or any part of body in fastener discharge area of
tool; 2.) Never point tool at anyone; 3.) Do not pull the trigger or depress the trip as
accidental actuation may occur, possibly causing injury.
OPERATION
Always handle the tool with care: 1.) Never engage in horseplay; 2.) Never pull the trigger
unless nose is directed toward the work; 3.) Keep others a safe distance from the tool while
tool is in operation as accidental actuation may occur, possibly causing injury.
The operator must not hold the trigger pulled on contact arm tools except during fastening
operation as serious injury could result if the trip accidentally contacted someone or
something, causing the tool to cycle.
Keep hands and body away from the discharge area of the tool. A contact arm tool may
bounce from the recoil of driving a fastener and an unwanted second fastener may be
driven possibly causing injury.
Check operation of the contact arm mechanism frequently. Do not use the tool if the arm
is not working correctly as accidental driving of a fastener may result. Do not interfere with
the proper operation of the contact arm mechanism.
Do not drive fasteners on top of other fasteners or with the tool at an overly steep angle as
this may cause deflection of fasteners which could cause injury.
Do not drive fasteners close to the edge of the work piece as the wood may split, allowing
the fastener to be deflected possibly causing injury.
MAINTAINING THE TOOL
When working on air tools note the warnings in this manual and use extra care when
evaluating problem tools.
