LOADING THE TOOL
1. Open the magazine: Pull pusher back to engage latch. (Fig 8)
2. Hold nailer down with magazine tilted downwards. Insert sticks of nails. (Fig 9)
3. Close magazine: Release pusher by first puling back on the pusher and then pressing the release tab. Slide pusher against the
nails. (Fig 10)
Note: Use only fasteners recommended by Bostitch for use in Bostitch tools or nails which meet Bostitch specifications.
Warning! When installing metal connectors with the F21PL & N89RH17-2MCN: Use only one stick of metal connector nails at a
time.
REMOVING NAILS (FIG 11)
1. Disconnect the tool from the air supply
2. Pull pusher back until it is securely engaged
3. Slide nails back to opening and push out
CAUTION: The pusher and pusher spring (constant force spring).
Caution must be used when removing nails, as if pusher is disengaged from latch it could spring forward potentially pinching
your hand.
Extra caution should be taken when carrying out maintenance on the magazine area of the tool. The spring is wrapped around
but not attached to a roller. If the spring is stretched beyond its length, the end will come off the roller and the spring will roll up
with a snap, with a chance of pinching your hand. Also the edges of the spring are very thin and could cut your hand. Care must
also be taken to insure no permanent kinks are put in the springs as this will reduce the springs force.
