Note (MFN201): Because it is a manual tool, sufficient force is required when using the MFN201 to completely
drive flush a single fastener with one strike of the hammer. Do not use the hammer twice on the same fastener,
unless the ratcheting mode is engaged.
Note (MFN201, MIIIFS, MIIIFN): Never hit the plunger with the metal face of the hammer.
CAUTION (MIIIFS & MIIIFN): Installing Pre-finished Flooring
These tools were designed for use in installing unfinished hardwood flooring. They can be used to install pre-
finished flooring, however caution must be used to ensure that the finish is not damaged by the tool. It is
recommended that the tools be tested on a sample section to be certain that the tool and technique of use do
not leave marks on the finish. This procedure should be followed before each job due to variations in flooring
and tool condition.
LOADING THE TOOL
MFN201 (Fig. 4)
1. Release the pusher spring clip and remove pusher blade. (fig 4a)
2. Load fasteners into guide channel.
3. Insert rounded end of pusher blade into channel to retain fasteners.
4. Latch pusher spring clip to notched end of pusher blade. Ensure sufficient engagement ofpusher blade for
smooth fastener feeding. (fig 4b)
MIIIFS (Fig. 5)
1. Pull cover open and insert stick of staples.
2. Push cover forward until the pin snaps into place, locking the cover.
MIIIFN (Fig. 6)
1. Insert nails.
2. Pull pusher assembly back (fig 6a) to engage pusher to strip of nails.
Note: Use only fasteners recommended by Bostitch for use in Bostitch tools or fasteners that meet Bostitch
specifications.
TOOL MAINTENANCE
CAUTION: Pusher spring (constant force spring). Caution must be used when working with the
spring assembly. The spring is wrapped around, but not attached to, a roller. If the spring is extended 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. Care must also be taken to insure no permanent
kinks are put in the spring as this will reduce the spring's force.
MALLET MAINTENANCE
Over time the rubber face on the mallet may became worn, cracked, or chipped. These are signs that a new
rubber face will need to be installed.
To remove old rubber face:
1. Secure the rubber face in a bench vise. (Fig 7)
2. Pull upward on the handle till the rubber face is released from the steel stud.
To install a new rubber face on the mallet, we recommend doing it in the shop with the use of an arbor press. If
you must do it manually follow these instructions.
1. Secure the mallet head in a bench vise. (Fig 8)
