MAINTAINING THE TOOL
When working on air tools note the warnings in this manual and use extra care when
evaluating problem tools.
SAFETY INSTRUCTIONS
E
YE PROTECTION
w
hich conforms to ANSI specifications and provides protection against
f
lying 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
e
quipment 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
s
pectacles and face shields alone do not provide adequate protection.
C
AUTION:
A
dditional Safety Protection will be required in some environments. For example,
t
he 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
D
o 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 psig (
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.
This nailer produces SPARKS during operation. NEVER use the nailer near flammable substances,
gases or vapors including lacquer, paint, benzine, thinner, gasoline, adhesives, mastics, glues or
any other material that is -- or the vapors, fumes or by-products of which are -- flammable,
combustible or explosive. Using the nailer in any such environment could cause an EXPLOSION
resulting in personal injury or death to user and bystanders.

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
t
ool. Eye protection is required to guard against flying fasteners and debris, which could
c
ause severe eye injury.
T
he 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.
TO PREVENT ACCIDENTAL INJURIES:
• Never place a hand or any other part of the body in nail discharge area of tool while
the air supply is connected.
•
Never point the tool at anyone else.
• Never engage in horseplay.
• Never pull the trigger unless nose is directed at the work.
• Always handle the tool with care.
• Do not pull the trigger or depress the trip mechanism while loading the tool.

TOOL OPERATION
EYE PROTECTION which conforms to ANSI specifications and provides protection against
f
lying particles both from the FRONT and SIDE should ALWAYS be worn by the operator and
o
thers in the work area when connecting to air supply, loading, operating or servicing this
t
ool. 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
s
pectacles and face shields alone do not provide adequate protection.
BEFORE HANDLING OR OPERATING THIS TOOL:
I
. READ AND UNDERSTAND THE WARNINGS CONTAINED IN THIS MANUAL.
II. REFER TO “TOOL SPECIFICATIONS” IN THIS MANUAL TO IDENTIFY THE OPERATING SYSTEM ON
YOUR TOOL.
OPERATION
The operator must not hold the trigger pulled on contact trip 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 trip tool may
bounce from the recoil of driving a fastener and an unwanted second fastener may be
driven, possibly causing injury.

MAINTAINING THE PNEUMATIC TOOL
When working on air tools, note the warnings in this manual and use extra care evaluating
problem tools.
CAUTION: Pusher spring (constant force spring). Caution must be used when working with the spring
assembly. The spring is wrapped around, but not attached to, a roller. If the spring is extended beyond
its length, the end will come off the roller and the spring will roll up with a snap, with a chance of
pinching your hand. Also the edges of the spring are very thin and could cut. Care must also be taken
to insure no permanent kinks are put in the spring as this will reduce the springs force.
