allowed to recontact work surface before trigger is
released an unwanted fastener will be fired.
• Choice of triggering method is important. Check
the manual for triggering options.
BUMP ACTION TRIGGER
• When using the bump action trigger, 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 "bump" actuating the framing nailer,
always keep tool in control. Inaccurate placement
of tool can result in misdirected discharge of a
fastener.
SEQUENTIAL ACTION TRIGGER
• When using the sequential action trigger, do
not actuate the tool unless the tool is placed
firmly against the workpiece.
• DEPTH ADJUSTMENT: To reduce risk of
serious injury from accidental actuation when
attempting to adjust depth, ALWAYS;
• Lock OFF trigger.
• Disconnect air supply.
• Avoid contact with trigger during adjustments.
• Do not drive nails 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:
• lead from lead-based paints,
• crystalline silica from bricks and cement and
other masonry products, and
• arsenic and chromium from chemically-treated
lumber.
FIG. M 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.
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),
FIG. N
• ANSI S12.6 (S3.19) hearing protection,
• NIOSH/OSHA/MSHA respiratory protection.
BEFORE OPERATING THIS TOOL, CAREFULLY READ
AND UNDERSTAND ALL INSTRUCTIONS IN THE
"IMPORTANT SAFETY INSTRUCTIONS" SECTION.

ASSEMBLY
WARNING: Lock off trigger, disconnect air line from
tool and remove fasteners from magazine before
making adjustments or personal injury may result.

WARNING: Keep fingers AWAY from trigger when not
driving fasteners to avoid accidental firing. Never carry
tool with finger on trigger. In "Contact Bump Actuation
Mode" tool will fire a fastener if safety is bumped while
trigger is depressed.

causes the tool to operate in this mode.
The black trigger with imprinted on the side,
(Cat.# D510020 kit) is the bump action trigger and
permits the tool to be actuated in this manner.
