OPTIONAL ACCESSORY

⅜ Sequential Trip Mechanism Kit (Code No.881-973)

With the sequential Trip Mechanism Kit, 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

prevented.

APPLICATIONS

⅜ Floor and wall framing.

⅜ Truss build-up, Window build-up.

⅜ Subflooring and roof decking.

⅜ Wall sheathing.

⅜ Mobile home and modular housing construction.

PREPARATION PRIOR TO OPERATION

1. Prepare the hose

Be sure to use the hose provided with minimum

8 mm (5/16”) 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

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.

Lubrication 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. Load nails

(1) Insert nail strip into rear of magazine. (See Fig. 2)

(2) Slide the nail strip forward in the magazine.

The nail strip should pass the nail stopper.

(3) Pull the nail feeder (B) back to engage the nail feeder

(A) to the nail strip.

NOTE:

⅜ Use nail strip of more than 5 nails.

The Nailer is now ready to operate.

Removing the nails:

1 Pull the nail feeder (B) backward.

2 Return the nail feeder (B) forward quietly while

pushing the nail feeder (A).

3 Push the nail stopper toward the magazine side, and

pull out nails from the back of the magazine.

CAUTIONS:

⅜ To prevent unintentional operation, never touch the

trigger or place the top end of the push lever on a

work bench on floor. Also, never face the nail outlet

toward any part of a person.
