WARNING: After driving a fastener, tool may
bounce back ("recoil") causing it to move away
from the work surface. To reduce risk of injury
always manage recoil by:
• Always maintaining control of tool.
• Allowing recoil to move tool away from
work surface.
• Not resisting recoil such that tool will be forced
back into the work surface. In "Contact Actuation
Mode," if workpiece contact is allowed to
re‑contact work surface before the trigger is
released, an unintended discharge of a fastener
will occur.
• Keeping face and body parts away from tool.

the magazine.

WARNING: When maintaining the tool:
• Always shut off air supply, and disconnect tool
from air supply when not in use.
• When working on air tools note the warnings in
this manual and use extra care when evaluating
problem tools.

Additional Safety Information


WARNING: ALWAYS use safety glasses. Everyday
eyeglasses are NOT safety glasses. Also use face or
dust mask if cutting operation is dusty. ALWAYS WEAR
CERTIFIED SAFETY EQUIPMENT:
• ANSI Z87.1 eye protection (CAN/CSA Z94.3),
• ANSI S12.6 (S3.19) hearing protection,
• NIOSH/OSHA/MSHA respiratory protection.

WARNING: Some dust created by power sanding,
sawing, grinding, drilling, and other construction
activities contains chemicals known to the State
of California to cause cancer, birth defects or
other reproductive harm. Some examples of these
chemicals are:
• lead from lead‑based paints,
• crystalline silica from bricks and cement and other
masonry products, and
• arsenic and chromium from chemically‑
treated lumber.
Your risk from these exposures varies, depending on
how often you do this type of work. To reduce your
exposure to these chemicals: work in a well ventilated
area, and work with approved safety equipment, such
as those dust masks that are specially designed to
filter out microscopic particles.
• Avoid prolonged contact with dust from power
sanding, sawing, grinding, drilling, and other
construction activities. Wear protective clothing and
wash exposed areas with soap and water. Allowing
dust to get into your mouth, eyes, or lay on the skin may
promote absorption of harmful chemicals.
