that fasteners are set into the material and not pushed completely
through. (Fig. P)
• Keep hands and body parts clear of
immediate work area. Hold workpiece
with clamps when necessary to keep
hands and body out of potential harm. Be
sure the workpiece is properly secured
before pressing the stapler against the
material. The contact trip may cause the
work material to shift unexpectedly.
(Fig. Q)
• Do not use tool in the presence of
flammable dust, gases or fumes. The
tool may produce a spark that could ignite
gases causing a fire. Driving a fastener into
another fastener may also cause a spark.
(Fig. R)
• Keep face and body parts away from
back of the tool cap when working
in restricted areas. Sudden recoil can
result in impact to the body, especially
when stapling into hard or dense material.
(Fig. S)
• Grip tool firmly to maintain control
while allowing tool to recoil away
from work surface as fastener is
driven. In "Contact Actuation Mode" if
contact trip is allowed to recontact work
surface before trigger is released an
unwanted fastener will be fired.
• CONTACT ACTION TRIGGER
• When using the contact action trigger,

• Do not drive fasteners blindly into
walls, floors or other work areas.
Fasteners driven into live electrical wires,
plumbing, or other types of obstructions
can result in injury. (Fig. U)
• Stay alert, watch what you are

doing and use common sense
when operating a power tool. Do
not use tool while tired or under
the influence of drugs, alcohol, or
medication. A moment of inattention
while operating power tools may result in serious personal injury.
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:

be careful of unin tentional double
fires resulting from tool recoil.
Unwanted fasteners may be driven if
the contact trip is allowed to accidentally
re-contact the work surface. (Fig. T)
TO AVOID DOUBLE FIRES:
• Do not engage the tool against the
work surface with a strong force.
• Allow the tool to recoil fully after each actuation.
• Use sequential action trigger.
• When "contact" actuating the stapler, always keep
tool in control. Inaccurate placement of tool can result in
misdirected discharge of a fastener.
