Dust, dirt and other particles

in the system can cause premature wearing of the major components. Cylinder, piston, and o-rings are especially sensitive to wear caused by dirt abrasion. 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.

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®

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 freedom to use any configuration of quick connect 3/8” NPT Fitting. Install the 3/8” NPT Fitting into the supplied adapter and gently tighten.

Page 8

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

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

Regulator pressure is

90-95 PSI. Note:

of 95-100 PSI in order to countersink the nail. Ensure that tool is in proper working order and that there is no leaking of air. If there

is an air leak, of Owner’s Manual. 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.

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.

Some materials may require a higher pressure

! Refer to the Repair and Maintenance section

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

Ram Cap (Ref. No. 47 Pg. 17). 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 Ram can 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 Ram Cap is struck by

Hammer and the Safety Trigger is not depressed.

The

PORTAMATIC

Nailer is user-friendly and following these simple instructions, will insure a very high quality Hardwood Flooring installation. If the nail is not properly seated, increase pressure incrementally until nail is seated.

10. DO NOT EXCEED 110 PSI!

Clearing A Jam

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

Once Gate is open, clear jam.

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.) 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!

from power source until jam is cleared!

Figure 7

Pull the tab of Gate Clip to open Gate. Opening

the G ate 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 from the 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

FIGURE 9

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.

FIGURE 10

Page 11

If the Seal is damaged or has separated from the Main Valve, replace Main Valve. The Seal and Main Valve have been assembled permanently at the Manufacturing Facility and can not be repaired in the field.

5. Inspect other O-Rings as described in “Replacing O-Rings” section Figures 12-16 to

ensure proper positioning and distortion has not taken place. If any of the O-Rings are distorted, refer to the proper Figure and replace.

6. After inspecting and/or replacing O-Rings, assemble Nailer and connect to power

supply.

Replacing O-Rings

Use Texaco Molytex® EP 2 Grease or equivalent. Do not use greases that cause ORings to swell. The use of these types of greases may prevent Nailer from operating properly.

NEVER USE OIL FOR LUBRICATION!

Removing and Re-Installing the Cylinder Assembly

1. After removing the Extension Handle and Main Valve Housing, remove the Head

Gasket, Valve Body Assembly and the Piston Assembly.

2. Turn the Nailer over and tap lightly on a hard surface carefully insuring not to damage

the Body in anyway.

3. The Cylinder should dislodge enough to enable grasping and removing.

4. To replace the Cylinder,
