Operating The Nailer
(Continued)
CHANGING SHOE PLATES
1. Disconnect the air supply from
the nailer.
2. Using provided 4 mm wrench,
remove the three shoe screws.
3. Remove shoe plate; place new or
alternate shoe. Make sure shoe is in
the “up” position when attaching
(See Figure 6).
4. Reattach screws (apply a good
quantity of threadlock glue on
screw threads before installing;
tighten firmly).
SHOE PLATE SIZES
There are two shoe plates included
with this tool. The 1/4" thin plate is for
use on 3/4" thick hardwood flooring.
The 5/16" thick plate is for use on 1/2"
thick hardwood flooring.
To
prevent
damage to the flooring, use the correct
shoe for the flooring being installed.
RACKING THE FLOORING
(SEE FIGURE 7)
First refer to flooring manufacturer’s
preparation procedures regarding
moisture content and floor
preparation before laying the flooring
boards.
To correctly install hardwood flooring,
it must be properly racked before
being nailed into place. After placing
the first board, follow these
instructions to rack the flooring:
1. Place flooring groove onto the
tongue of previously installed
board.
2. Use the rubber end of the mallet to
“pop” the tongue into the groove.
3. Use the metal end of the mallet to
rack the board tightly against
adjacent board.
FIRING THE NAILER
1. Connect the air supply to the nailer.
Note:
Make sure the rubber bumper
on the flooring nailer is in the up
position before adding the air hose,
if not, the nailer may cycle.
2. Load fasteners (see Loading the
Nailer Section).
3. Place the tool on the floor as
shown in Figure 8 with the shoe
plate resting on the racked floor
board. Make sure the fastener
ejection nozzle is firmly placed
against the board tongue.
4. Strike the tools rubber bumper
firmly with the rubber end of the
mallet. The tool should cycle and
drive fastener into floor board.
Do NOT
fire the
tool unless it is securely placed. If tool
is not securely placed, there is a risk of
flying fasteners that may cause death
or serious injury.

FASTENER DEPTH & PLACEMENT
Refer to Figure 9 for correct depth
placement of fasteners in hardwood
tongue. Use a scrap piece of the
flooring to help determine correct air
pressure settings. Damage to the
tongue upon installation will make
remaining project difficult.
