Nailing Tongue And Groove Flooring

Using the PORTAMATIC® Nailer

1. Install the Face Nailing Shoe on the PORTAMATIC®Nailer (See Shoe Changing

Section Pg. 5 Figure 6).

2. 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.

3. Be careful to use the Brown Cap of the Hammer to hit the RamHead of the

PORTAMATIC®Nailer and the Gray Cap on the Flooring. Using the Brown Cap to

hit the Flooring will destroy the Cap.

4. Depress Safety Trigger, and strike Ram Head of the PORTAMATIC®Nailer with the

Face Nailing Shoe installed.

5. After striking the Ram Head, the actuating cycle of the PORTAMATIC®Nailer

drives one nail into the Flooring.

6. When the nail has been completely driven, the PORTAMATIC®Nailer will

automatically reset, and is ready to be moved to the next position and drive another

nail.

7. Be careful not to drive one nail on top of another. Damage to the Nailer might result or

injury from sparks or a sliver of metal that might break away if this should occur.

8. If a nail is driven on top of another or a jamoccurs, refer to the “Clearing a Jam”

section of the manual on page 9.

9. Slide the PORTAMATIC®Nailer along the Flooring to the location at which you

desire to drive the next nail.

10.Continue until four (4) rows of Flooring have been Face Nailed.

11.Remove the Face Nailing Shoe Accessory from the PORTAMATIC®Nailer and

install the Tongue and Groove Nailing Shoe (See Shoe Changing Section Pg. 5 Figure 5).

12.Place the groove of the fifth row of Flooring over the tongue of the fourth row of

Flooring and tighten using the Hammer. Depress Safety Trigger, and strike RamHead

of the PORTAMATIC®Nailer with the Tongue and Groove Nailing Shoe installed.

13.Slide the PORTAMATIC® Nailer along the tongue of the Flooring to the location at

which you desire to drive the next nail.

14.Continue Step 11 until you have completely nailed all but the last five (5) rows of

Flooring.

15.Remove the Tongue and Groove Nailing Shoe fromthe PORTAMATIC Nailer and

install the Face Nailing Shoe (See Shoe Changing Section Pg. 5 Figure 6).

16.Install and nail in place the remaining five (5) rows of Flooring using the

PORTAMATIC®Nailer with the Face Nailing Shoe installed.

Operating Instructions

Safety Requirements

1. WEAR SAFETY GLASSES and safety shoes for protection against foreign objects.

2. NEVER use a Hammer with a loose head or splintered handle.

3. USE ONLY nails from Porta-Nails, Inc.

4. Air supply hoses should have a minimum working pressure rating of 150 PSI or 150

percent of the maximum pressure produced in the power source, whichever is higher.

5. Check all hoses before connecting to ensure that they are free fromdirt, grit, or

particles that could alter the performance of the tool.

6. An airline Filter and Regulator are required.

7. The PORTAMATIC®pneumatic Nailer requires Clean, Dry Air. DO NOT USE

IN-LINE OILERS WITH THE PORTAMATIC®.Dust, dirt and other particles

in the systemcan cause premature wearing of the major components. Cylinder, piston,

and o-rings are especially sensitive to wear caused by dirt abrasion.

8. Adjust the airline Regulator to 90-95 PSI. Be sure that the tool is not pointed at you or

others when it is connected to the air supply source.

Note: Some materials may require a higher pressure of 95-100 PSI in order to

countersink the nail.

9. NEVER use a defective tool. Replace worn or damaged parts immediately. Be sure

that the Safety Trigger and operating mechanisms operate correctly and that all screws

and seals are securely tightened at all times.

Installing A Fitting

Before using the PORTAMATIC®Nailer, a 3/8” NPT Fitting must be installed. The

PORTAMATIC® Nailer has an adapter installed to accept a 3/8” NPT fitting. This

provides the owner the advantage of installing the preferred 3/8” NPT Fitting of choice.

This allows the freedomto use any configuration of quick connect 3/8” NPT Fitting.

Install the 3/8” NPT Fitting into the supplied adapter and gently tighten.

IMPORTANT: The bottomhole of the PORTAMATIC®that is plugged should

NEVER be removed. If plug is removed, the PORTAMATIC®Nailer will not perform

correctly and serious damage may occur.

Loading the Tool

Insert nails into the nail track and pull back the Pusher Bracket (Ref. No. 19 Pg. 17) to

provide pressure against the nails. IMPORTANT! For proper operation, never use the

PORTAMATIC®Nailer with less than a 2 inch stack of nails remaining in the nail

track.

Operation

1. After connection with power source is made, check to be sure that the airline

Regulator pressure is 90-95 PSI. Note: Some materials may require a higher pressure

of 95-100 PSI in order to countersink the nail.

2. Ensure that tool is in proper working order and that there is no leaking of air. If there

is an air leak, Disconnect Immediately! Refer to the Repair and Maintenance section

of Owner’s Manual.

3. After being sure tool is operable, place tool in position to be used. Always place the

tool in proper position against the Flooring to be nailed before striking the Ram.

4. The PORTAMATIC®Nailer has a Safety that prevents accidental firing if Ram Cap

is hit while connected to power source. Squeeze Safety Lever to enable the Nailer.

Releasing the Safety Lever re-engages the Safety and renders the Nailer in operable.

5. To operate tool, depress Safety Trigger while tool is in position of use, and strike the

Ram Cap (Ref. No. 47 Pg. 17).

6. If on the first initial operation a nail does not eject into the Flooring, repeat Hammer

blow. This will ensure that the Driver Blade/Piston is properly reset to allow the

Driver Blade/Piston (Ref. No. 36 Pg. 17) to be in the correct position to drive the nail.

7. DO NOT OVERPOWER THE NAILER – A minimal stroke of the hammer will

fire the Nailer. If the Flooring is warped or bowed, the Ramcan be hit firmly to

tighten the Flooring. Try to avoid this constant wear, as abusive blows by the hammer

could damage tool.

8. Note: The PORTAMATIC®Nailer will not drive a nail if the RamCap is struck by

Hammer and the Safety Trigger is not depressed.

9. The PORTAMATIC®Nailer is user-friendly and following these simple

instructions, will insure a very high quality Hardwood Flooring installation.

10. If the nail is not properly seated, increase pressure incrementally until nail is seated.

DO NOT EXCEED 110 PSI!

Clearing A Jam

1. In the event of a jam, the Gate (Ref. No. 22 Pg. 17) can be opened by pulling the gate

clip upward. (See Figures 7 and 8) (The Shoe does not have to be removed to open

and close the Gate.)

2. IMMEDIATELY DISCONNECT from power source until jam is cleared!

3. Once Gate is open, clear jam.

4. Inspect to be sure no damage has been done to the Driver Blade, Guide, Gate,

Magazine or Pusher Finger. (If damage has occurred, repair immediately before

connecting to the power source and continuing.)

5. Close Gate by placing the Gate Clip Wire over the two hooks of the Guide as shown

and press down to seat and lock the Gate in place. Make sure the Gate is properly

reseated.

6. DO NOT OPERATE WITH GATE OPEN!

Figure 7

Pull the tab of Gate Clip to open Gate. Opening

the Gate allows access to the Nail Chamber.

Figure 8

To Close Gate, reset the Gate tab ends under the ears of

the Guide. Reset the Gate Clip Wire over the two hooks

of the Guide and pivot Gate Clip down until seated.

Ensure Gate is secure before continuing operation.

Repair and Maintenance

IF AIR IS LEAKING FROM THE NAILER DISCONNECT IMMEDIATELY!

If air is leaking fromthe Nailer, inspect to make sure Main Housing or Extension

Handle is not cracked or damaged. If Main Housing and Extension Handle are not

damaged, the head gasket or an O-Ring may need to be replaced. Refer to Exploded view

Page 17 for Disassembly.

1. Remove Extension Handle (Ref. No. 15 Pg. 17) from Main Body and Main Valve

Housing (Ref. No. 46).

2. Remove Main Valve Housing Screws (4) and remove Main Valve Housing.

3. Check the Head Gasket (Ref. No. 6) to ensure proper positioning and/or check for a

tear or pinched edge around the screw holes.

MAIN

BODY

4. If Head Gasket does not look damaged, check Main Valve Upper and Lower O-Rings

and Seal. Remove Ram Head Set Screw and inspect. Replace if O-Ring is broken or

flattened in one or more spots. Refer to Figure 11 in the “Replacing O-Rings” section.
