The first two strips of flooring and the last six (or strips that measure4. less than 13-1/2” from the wall) should be Face nailed with the Face
Nailing Shoe installed on the Porta-Nailer or by hand.
The Porta-Nailer MUST be held firmly, but not over-tightly in the5. 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.
DO NOT OVERPOWER THE PORTA-NAILER – Strike it firmly but6. NOT HARD, and then strike it again until the Ram returns. The Ram
does not return until the nail is properly seated.
Do not attempt to nail the last six strips (or strips that measure less7. than 13-1/2” from the wall) of flooring down with the Angled Shoe
installed. Switch and install the Face Nailing Shoe or face nail by
hand.
The Porta-Nailer system is user-friendly and following these simple
instructions, will insure a perfect hardwood flooring installation. Contact
our Customer Service Dept. [phone] if you encounter flooring
which the Porta-Nailer does not properly position the fastener.

The Porta-Nail is 2” long and the PORTA-NAILER with the standard shoe
drives the nail into the Tongue and Groove Flooring at a 45-degree angle.
The orientation of the nail is as depicted in wood floor joist construction.
In applications where Tongue and Groove Flooring is laid over concrete or
Hydronic Heating Systems, the 1-1/2” or 1-3/16” Porta-Nail is used so that
the Nail will not protrude through the sub-floor. Refer to the “Porta-Nail

Nail 2” long is available for applications requiring a non-corrosive nail.

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).
Prior to laying the felt, identify the nail line attaching the Sub Floor to1. the joists by marking the nail line on each wall. After laying the felt,
transfer the nail line to the top of the felt. When nailing, the Floor,
stay left or right of the chalk line.
After squaring the Floor and allowing for expansion as recommended2. 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. Face Nail in place
by hand or by using the Model 402 Nailer with the Face Shoe (Sold
Separately) installed. (See Shoe Changing Section Pg. 8).
After Face nailing the First (1st) row of Flooring, (See Figure 8) place3. the groove of the Second (2nd) row of Flooring over the Tongue of the
First (1st) row of Flooring and drive snug using the rubber knob end
of the Porta-Nailer Hammer and Face nail in place just as the First
(1st) Row of Flooring.
You are now ready to Blind Nail the field of Flooring.4.
Position the Model 402 Nailer along the Tongue edge of the Third5. (3rd) Row of Flooring in the manner shown in Figure 8. (THE
FIELD SHOULD BE NAILED ONLY THRU THE TONGUE.
SEE ILLUSTRATION ON PAGE 22).
Strike the Ram Head (Ref. No. 21) with the metal end of the Hammer6. Head to drive the Nail.
Continue to strike the Ram Head (Ref. No. 21) until the Ram returns7. to its original position. (It usually takes two blows to drive a nail.)
If, after striking the Ram Head (Ref. No. 21), the Ram does not return8. to its original position, it is a warning that the Nail has not been
completely driven.
When the Nail has been completely driven, the Ram will return to its9. original position.

10
Be careful not to drive one Nail on top of another. Damage to the10. Nailer might result if this should occur.
Slide the Nailer along the tongue of the board to the location at which11. you desire to drive the next nail. (8-10 inches is the general rule of
thumb.) Try to get a nail in each Joist.
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 (or13. boards measuring less than 13-1/2” from the wall) have been nailed in
place.
Face Nail the last Six (6) Rows of Flooring or boards measuring less14. than 13-1/2” from the wall.
