NAIL SELECTION

Wire collated nails and sheet collated nails can be driven

with this tool.

Choose a suitable nail from Fig. Nails which are not

shown in Fig. can not be driven with this tool. Nails are

linked and rolled.

⅜ Copper nails should be used only for copper sheet or of

driving into soft materials. Work with a maximum of

two sheets of copper plate at a thickness 0.35 mm

(.014"). Never work with three or more sheets at a time.

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 atten-

tion to the output pressure, capacity, and piping on the

air compressor, so that air pressure does not exceed

the specified limit. Note that excessive pressure 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) Load nails in the magazine

⅜ Grip the nail guide and knob with fingers. Then

depress the knob to open the nail guide towards

the left (See Fig. 2).

⅜ Adjust the position of the nail holder according to the

length of the nail (Fig. 3).

For adjustment, turn the nail holder 1 counterclockwise

about 90 degrees. Move the nail holder 2 up and

down, adjust to the length of a nail to be used, and

adjust the surface of the nail holder to the marked

position of the magazine.

Turn the nail holder 3 clockwise (about 90 degrees)

until it goes click (Fig. 4).

OPTIONAL ACCESSORY

⅜ Sequential Fire Parts Set (Code No.881-012)

With the sequential fire parts,the nail is driven only

by squeezing the trigger after pushing down the

push lever.

By installing these parts, driving nails into improper

positions and unexpected firing of nails caused by

accidental operation of the push lever can be pre-

vented.

APPLICATIONS

⅜ For retaining various types of internal materials.

⅜ For retaining various types of sheet metal (thickness

of 0.35 mm (.014") or less).

⅜ General construction operations.

CAUTION

⅜ To avoid accidents when working with wood or sheet

metal, be sure to use the special linked nails for wood

and sheet metal. Never work with more than a maxi-

mum of three layers of materials with an individual

thickness of 0.35 mm (.014"). Working with four or

more layers at a time is dangerous.
