NAILING TONGUE AND GROOVE FLOORING
Your Model 402 Nailer is furnished with two (2) Shoe Bases
(Ref. No. 5). When nailing 3/4” thick flooring, both of these bases are
used. When nailing 33/32” thick flooring, only use one (1) Shoe Base
(Ref. No. 5).
1. After squaring the Floor and allowing for expansion as
recommended by the Wood Flooring Industry (NWFA, NOFMA
and MFMA), place the grooved edge of the first row of Flooring
towards the wall on the side of the room from which you are
starting. Nail in place using the Model 402 Nailer with the Face
Shoe installed. (See Shoe Changing Section Pg. 8).
2. After nailing the First (1
groove of the Second (2
st
First (1
) row of Flooring and drive snug using the rubber knob end
of the Porta-Nailer Hammer and nail in place just as the First (1
st
) row of Flooring, (See Figure 8) place the
nd
) row of Flooring over the Tongue of the
st
)
Row of Flooring.
3. Change over to use the Angle Shoe (See Shoe Changing Section Pg.
8), and place the groove of the Third (3
tongue of the Second (2
nd
) row of Flooring and drive snug using the
rd
) row of Flooring over the
rubber knob end of the Porta-Nailer Hammer .
4. Position the Model 402 Nailer with the Tongue Nailing Shoe
rd
Installed on the tongue of the Third (3
) Row of Flooring in the
manner shown in Figure 8. (THE FIELD SHOULD BE NAILED
ONLY THRU THE TONGUE. SEE ILLUSTRATION ON
PAGE 22).
5. Strike the Ram Head (Ref. No. 21) with the metal end of the
Hammer Head to drive the Nail.
6. Continue to strike the Ram Head (Ref. No. 21) until the Ram returns
to its original position. (It usually takes two blows to drive a nail.)
7. If, after striking the Ram Head (Ref. No. 21), the Ram does not
return to its original position, it is a warning that the Nail has not
been completely driven.
8. When the Nail has been completely driven, the Ram will return to its
original position.
9. Be careful not to drive one Nail on top of another. Damage to the
Nailer might result if this should occur.
9
Page 10
10. Slide the Nailer along the tongue of the board to the location at
which you desire to drive the next nail. (8-10 inches is the general
rule of thumb.) Try to get a nail in each Joist.
11. Continue Steps 5-10 until you have completely nailed the board.
12. Repeat Steps 4-11 until all but the last Six (6) Rows of boards have
been nailed in place.
13. Change over to use the Face Nailing Shoe (See Shoe Changing
Section Pg. 8), and install the last Six (6) Rows of Flooring as shown
in Figure 8.

BRIEF INSTRUCTIONS FOR USE OF
THE PORTA-NAILER SYSTEM
Always wear safety glasses AND safety shoes.
OPERATION FOR USE OF THE
PORTA-NAILER SYSTEM
1. This tool is designed to properly seat the nail with one or SEVERAL
blows of the Hammer.
2. Tap the flooring into place with the non-marring rubber side of the
Hammer.
3. Strike the Rubber Cap of the Nailer with the iron side of the
Hammer.
4. The first two strips of flooring and the last six MUST be nailed with
the Face Nailing Shoe installed on the Porta-Nailer.
21
Page 22
5. The Porta-Nailer MUST be held firmly, but not over-tightly in the
hand so that the Porta-Nailer rests perfectly flat on the floor with the
lip of the shoe hanging over and against the edge of the strip being
nailed. As an aid to holding it flat against the floor, rest the toe of
your shoe on the rear of the Porta-Nailer Shoe.
6. DO NOT OVERPOWER THE PORTA-NAILER – Strike it firmly
but NOT HARD, and then strike it again until the Ram returns. The
Ram does not return until the nail is properly seated.
7. Do not attempt to nail the last six strips of flooring down with the
Angled Shoe installed. Switch and install the Face Nailing Shoe.
The Porta-Nailer system is user-friendly and following these simple
instructions, will insure a perfect hardwood flooring installation.
