Always observe the following safety precautions in addition to the safety in-
structions on pages 2 through 7 . Failure to do so may result in equipment dam-
age, property damage, or personal injury .
Disconnect battery pack from tool before assembly, adjustments, trouble-
shooting or changing accessories . Such preventive safety measures reduce the
risk of starting the tool accidentally, which may result in personal injury .
Use
equipment . Always wear eye
protection . Protective equipment such as a dust
mask, non-skid safety shoes, hard hat, or hear-
ing protection used for appropriate conditions
will reduce personal injuries .
This nailer operates only in a fully sequential
actuation mode . To fire a fastener, first the
Nosepiece must be fully depressed against the
workpiece, then the Trigger must be pressed .
To fire another fastener the Trigger and Nose-
piece must be released and the firing sequence
repeated .
Note: The Trigger has to be pressed within 2
seconds after the Nosepiece is fully pressed . If
the Trigger is pressed later, the nailer will revert
to a SAFE mode and the actuation sequence will
have to be repeated .
For optimal performance and reliable service
life, operate the nailer within the specified am-
bient temperature range .
Daily Inspection and Testing
Do not operate the nailer if it
does not pass daily inspec-
tion and testing . Operating a nailer that does not
pass the daily inspection and testing may result
in property damage and personal injury .
Perform the following inspections and tests us-
ing the Collated Magazine and Collated Nose-
piece before use each day, or if the nailer has
been dropped, receives a sharp blow, has been
jammed, etc . .
1 . Remove battery pack and all fasteners from
the Magazine .
2 . Inspect all screws, bolts, nuts, and pins on the
nailer . Any loose fasteners must be tightened .
3 . Press the Collated Nosepiece against a
workpiece . It must move smoothly .
4 . With the Collated Nosepiece pressed against
the workpiece, pull the Trigger . The nailer
must not operate .

5 . Insert the battery pack and turn on the nailer .
6 . Without pulling the Trigger press the Nose-
piece against a workpiece . The nailer must
not operate .
7 . Pull the Nosepiece away from the work al-
lowing it to reset . Pull the Trigger . The nailer
must not operate .
8 . Continue to pull and hold the Trigger and
push the Nosepiece against a workpiece .
The nailer must not operate .
9 . If Inspections confirm proper operation, the
nailer is ready for use .
Work Surface Suitability and
Center Punch Test
Do not drive fasteners into
unsuitable materials . Materi-
als that are too hard can cause the fastener to
deflect . Brittle materials can crumble and allow
the fastener to break through . Materials that are
too soft can allow the fastener to break through .
These conditions can result in property damage
or serious personal injury .
Before fastening into any work surface, check
the suitability and thickness of the work surface .
To check work surface suitability, apply the cen-
ter punch test .
Center Punch Test
Using the fastener as a punch, with a hammer,
strike a solid blow to the fastener to drive it into
the actual material you wish to fasten into, then
look for these results:
1 . If the point of the fastener is blunted, the
material is too hard and is unsuitable .
2 . If the material cracks or shatters, it is too
brittle and is unsuitable .
3 . If the fastener sinks into the material with
the hammer blow, the material is too soft
and is unsuitable .
4 . If the fastener makes a small indentation in the
work surface, it is suitable for fastening into .
