Cleaning The Jammed Fastener - Porter-Cable FN250B Instruction Manual

_qWARNING: 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. 23. 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
adjustment knob (A) Fig. 23: the adjustment knob has detents every Y4turn.
Rotate the knob (A) Fig. 23 clockwise to increase the depth of drive, rotate
the knob counterclockwise to decrease the depth of drive. 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.
A rubber nose cushion (B) Fig. 24, is provided to reduce marring of the work
surface. The rubber cushion can be removed to provide increased depth-of-
drive for toe-nailing applications.
[] WARNING: Disconnect tool from air supply before removing or re-
installing rubber cushion.
