5. Adjust directional exhaust deflector (A) Fig.
22, so that the exhaust air blast will be
directed away from the operator. The exhaust
deflector provides eight detented positions
for directing the exhaust blast away from the
operator. Grasp the deflector and rotate it to
the desired position for the current
application.
OPERATING INSTRUCTIONS
USING THE TOOL WITH DIFFERENT TRIGGERING OPTIONS
Complete all steps of PREPARING THE TOOL before using the tool.
This tool is shipped from the factory with a "single sequential actuation"
trigger which will limit the tool to firing method number 1 only.
A "contact actuation" trigger is available. The "contact actuation" trigger
allows the tool to be fired in either of two methods described below;
1. [SINGLE SEQUENTIAL ACTUATION TRIGGER]: To fire, grip tool firmly
to maintain control, position nose of tool onto work surface, depress
safety, and squeeze trigger to fire a fastener. Allow tool to recoil away
from work surface as fastener is driven. This "single sequential actuation"
method provides the most accurate fastener placement.
2. [CONTACT ACTUATION TRIGGER]: To fire, grip tool firmly to maintain
control, squeeze and hold trigger, push the tool firmly against work surface.
Allow tool to recoil away from work surface as fastener is driven. If safety
element is allowed to recontact work surface before trigger is released an
unwanted fastener will be fired. The tool will fire a fastener each time the
safety is depressed. This method is known as "contact actuation" and
allows very fast repetitive fastener placement.
IMPORTANT: The "contact actuation" trigger is available free-of-charge by
calling 1-800-321-9443 in the United States and Canada or 001-731-660-
9374 outside the United States and Canada, and providing tool model and
serial number. For identification purposes: the contact actuation trigger is
black and the single sequential actuation trigger is red.
DANGER: Keep fingers AWAY from trigger when not driving fasteners
to avoid accidental firing. Never carry tool with finger on trigger: tool
will fire a fastener if safety is bumped.
•
Never point tool at yourself or others in work area.
•
Never attempt to drive a fastener into material that is too
hard, or at too steep an angle, or near the edge of the workpiece. The
fastener can ricochet causing personal injury.
