Insert a strip of staples into the slit in the rear of the

magazine until it overpasses the staple stopper. The tool

accepts a strip of staples (84 pcs.) (Fig. 13)

Pull the pusher base all the way to the rear of the

magazine and return it slowly and gently to the original

position.

Removing staples (Fig. 14)

Hold the tool that the rear of magazine faces downward.

Pull the pusher base slightly, press the pusher from both

sides and release the staples. Return the pusher base

gently and slowly.

Press the staple stopper and then take out the staples

from the back of magazine.

Connecting air hose

Slip the air socket of the air hose onto the air fitting on the

stapler. Be sure that the air socket locks firmly into

position when installed onto the air fitting. A hose coupling

must be installed on or near the tool in such a way that the

pressure reservoir will discharge at the time the air supply

coupling is disconnected.

OPERATION

CAUTION:

• Make sure all safety systems are in working order

before operation.

1. To drive a staple, you may place the contact element

against the workpiece and pull the trigger, or (Fig. 15

& 16)

2. Pull the trigger first and then place the contact element

against the workpiece.

• No. (1) method is for intermittent stapling, when you

wish to drive a staple carefully and very accurately.

• No. (2) method is for continuous stapling.

CAUTION:

• However when the tool is set to the “Intermittent

stapling” mode, WITH THE TRIGGER HELD IN A

HALF-PULLED POSITION, an unexpected stapling

could occur, if contact element is allowed to re-contact

against the workpiece or the other surface under the

influence of recoil.

In order to avoid this unexpected stapling, perform as

follows;

- A. Do not place the contact element against the

workpiece with excessive force.

- B. Pull the trigger fully and hold it on for 1-2 seconds

after stapling.

• For No. (1) method, set the change lever to the

position.

For No. (2) method, set the change lever to the

position.

After using the change lever to change the stapling

method, always make sure that the change lever is

properly set to the position for the desired stapling

method. (Fig. 17 & 18)

Flooring

CAUTION:

• Tilting the tool too much tends to produce inflation on

the surface of workpiece. Holding it too upright tends to

cause a breakage of workpiece.

• Inflation or breakage on the stapled spot of workpiece

of workpiece may occur depending on many stapling

conditions, even when stapling holding the tool at the

specified angle. Try on some test samples before

actually stapling. (Fig. 19)

In stapling requiring accuracy, such as flooring, use in the

“Intermittent stapling” mode.

When stapling, hold the tool tilting it at the angles 50° -

55°shown in the figure.

Anti dry fire mechanism

This is the mechanism that the tool prevents to be fired

without nail.

Dry fire prevention automatically sets up when the rest of

nails get to last approximately 5 pieces.

Direction of exhaust air (Fig. 20)

The direction of exhaust air can be changed 360 degrees

of angle by turning the exhaust cover with a hand.

Removing jammed staples

WARNING:

• Always disconnect the hose before removing staplers.

Remove the staples from the magazine. (Refer to the

section titled “Removing staples“.) (Fig. 21)

Take out the hex wrench from the holder inside the

magazine cover by pushing it from the front. (Fig. 22)

Remove two screws securing the contact top with the hex

wrench.

The staple feeder guide will appear and clear jam.

When being still unable to remove the locked-up nails,

remove further two screws securing the front guide with

the hex wrench to clear jam.

MAINTENANCE

CAUTION:

• Always disconnect the air hose from the tool before

attempting to perform inspection or maintenance.

Maintenance of stapler

Always check the tool for its overall condition and loose

screws before operation. Tighten as required.

With tool disconnected, make daily inspection to assure

free movement of the contact element and trigger. Do not

use tool if the contact element or trigger sticks or binds.

Drain tool (Fig. 23)

Remove the hose from the tool. Place the tool so that the

air fitting faces down to the floor. Drain as much as

possible.

Cleaning of tool

Iron dust that adhere to the magnet can be blown off by

using an air duster.

Cap

When not in use, disconnect the hose. Then cap the air

fitting with the cap. (Fig. 24)

Storage

When not in use, the nailer should be stored in a warm

and dry place.
