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.
WARNING: Disconnect tool from air supply before performing
maintenance, clearing a jammed fastener, leaving work area,
moving tool to another location, or handing the tool to another
person.
WARNING: Clean and inspect tool daily. Carefully check for proper
operation of trigger and safety mechanism. Do Not use the tool
unless both the trigger and the safety mechanism are functional, or
if the tool is leaking air or needs any other repair.
The depth to which a fastener is driven is controlled by the depth adjustment
knob (A) Fig. 28. The depth of drive is factory adjusted to a nominal setting.
Test fire a fastener and check depth. If a change is desired, rotate the knob
(A) Fig. 28 clockwise to increase the depth of drive, rotate the knob
counterclockwise to decrease the depth of drive. The adjustment knob has
detents every
1
/4 turn. Test fire another fastener and check depth. Repeat as
necessary to achieve desired results.
The amount of air pressure required
will vary depending on the size of the
fastener and the material being
fastened. Experiment with the air
pressure setting to determine the
lowest setting that will consistently
perform the job at hand. Air pressure
in excess of that required can cause
premature wear and/or damage to
the tool.
CLEARING A JAMMED FASTENER
1. WARNING: Disconnect tool from air supply.
2. Open feeder cover and magazine cover. Remove any remaining fasteners
from the nailer.
3. Use a slender, soft steel rod to move the driver blade to its uppermost
position. Use needle nose pliers to
remove the jammed fastener (see
Fig. 29).
4. Follow instructions in
PREPARING THE TOOL to reload
fasteners.
5. Close the feeder cover, and
magazine cover, and secure with the
latch (See Fig. 23).
