APPLICATIONS

⅜ Construction – retaining various types of internal

materials.

PREPARATION PRIOR TO OPERATION

1. Prepare the hose

Be sure to use the hose provided with minimum

6 mm (1/4”) inside diameter.

NOTE

The air supply hoses must have a minimum working

pressure rating of 12.8 bar (180 psi) or 150 percent of

the maximum pressure produced in the air supply

system, whichever is higher.

2. Check on safety

CAUTIONS

⅜ Unauthorized persons (including children) must be

kept away from the equipment.

⅜ Wear eye protector.

⅜ Check the retaining screws which fix the exhaust

cover, etc. for tightness.

Check the nailer for air leaks and defective or rusty

parts.

⅜ Check whether or not the push lever works correctly.

Also check whether or not any dirt has adhered to the

moving parts of the push lever.

⅜ Recheck on operational safety.

BEFORE USE

1. Check the air pressure

CAUTION

The air pressure must be constantly maintained at 4.9

– 8.3 bar (70 – 120 psi.).

Adjust the air pressure between 4.9 to 8.3 bar (70 – 120

psi.) according to the diameters and length of nails

and hardness of the wood being nailed. Pay special

attention to the output pressure, capacity, and piping

on the air compressor, so that air pressure does not

exceed the specified limit. Note that excessive pres-

sure may affect overall performance, service life, and

safety.

2. Lubrication

(1) Prior to operating this nailer, be sure to provide an air

set between the air compressor and this device. Lubri-

cation through the air set offers smooth operation,

extended service life, and anticorrosion.

Adjust the oiler so that a single drop of oil is supplied

at intervals of 5 to 10 nailing cycles.

(2) It is recommended using the recommended oil (SHELL

TONNA). Other applicable oils are listed. Never mix

two or more types of different oils.

3. Loading nails

(1) Open the nail guide and the cover.

⅜ Place your finger on the nail guide and the knob. Push

the knob downward and open the nail guide to the left

(see Fig. 2).

(2) Insert nails in the magazine.

⅜ Adjusting the nail holder.

Pull the nail holder out in your direction and insert in

either the upper or lower groove. Insert in the upper

side when using nails that are 32 mm (1-1/4") or 38 mm

(1-1/2") in length.

Insert in the lower side when using nails that are 45

mm (1-3/4") or 50 mm (2") in length (see Fig. 3).

⅜ Insert the nails in the magazine (see Fig. 4).

CAUTION

Before inserting the nails in the magazine, be sure to

adjust the nail holder to a position that is appropriate

to the length of the nails you are using. Using the

nailer set at the wrong position will cause problems

with transfer of nails.

(3) Loading the nails in the nail guide.

⅜ Pull the first section of the nails from the magazine.

⅜ While pressing the sheet to the guide surface, insert

the first nail into the driving hole and the second nail

between feeder (A) and feeder (B).

Insert the nail so that the nails head and the upper side

sheet engage the guide slot (Fig. 5, 6).
