3. Depress the lock pin lightly and pull the pusher to

unhook it.

With the lock pin depressed, return the pusher

slowly and gently to the original position. Keep

depressing the lock pin until it passes through.

(Fig. 11)

Connecting air hose (Fig. 12)

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

stapler. Be sure that the air socket locks firmly into posi-

tion 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. Pull the trigger first and then place the contact ele-

ment against the workpiece. (Fig. 13 & 14)

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

against the workpiece and pull the trigger,

No. 1 method is for continuous stapling.

No. 2 method is for intermittent stapling, when you

wish to drive a staple carefully and very accurately.

CAUTION:

• However when the tool is set to the “Intermittent Sta-

pling” 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 work-

piece with excessive force.

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

after stapling.

For No. 2 method, the OPTIONAL SEQUENTIAL TRIP

TRIGGER (SINGLE SHOT PART) is used. Replace the

trigger part with this.

Direction of exhaust air (Fig. 15)

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 staples.

Remove the staples from the magazine.

Lift up the latch on the top of driver guide by hand.

(Fig. 16)

If the latch cannot be lift up by hand, insert a slotted bit

screwdriver in the gap between the latch and the door

and force it up. (Fig. 17)

Open the door and take out staples. (Fig. 18)

Place the latch spring on two hooks of the driver guide

and return it to its original position by pressing it.

(Fig. 19)

CAUTION:

• If the tip of staple driver has worn, staple jamming and

shallow driving will tend to occur. When this occurs,

have it repaired by Makita Authorized or Factory Ser-

vice Centers.

MAINTENANCE

CAUTION:

• Always disconnect the air hose from the tool before

attempting to perform inspection or maintenance.

• Never use gasoline, benzine, thinner, alcohol or the

like. Discoloration, deformation or cracks may result.

Maintenance of stapler

Always check the tool for its overall condition and loose

screws before operation. Tighten as required. (Fig. 20)

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.

(Fig. 21)

When the tool is not to be used for an extended period of

time, lubricate the tool using pneumatic tool oil and store

the tool in a safe place. Avoid exposure to direct sunlight

and/or humid or hot environment. (Fig. 22 & 23)

Maintenance of compressor, air set and air hose

(Fig. 24 & 25)

After operation, always drain the compressor tank and

the air filter. If moisture is allowed to enter the tool, it may

result in poor performance and possible tool failure.

Check regularly to see if there is sufficient pneumatic oil

in the oiler of the air set. Failure to maintain sufficient

lubrication will cause O-rings to wear quickly. (Fig. 26)

Keep the air hose away from heat (over 60°C, over

140°F), away from chemicals (thinner, strong acids or

alkalis). Also, route the hose away from obstacles which

it may become dangerously caught on during operation.

Hoses must also be directed away from sharp edges and

areas which may lead to damage or abrasion to the hose.

(Fig. 27)

To maintain product SAFETY and RELIABILITY, repairs,

any other maintenance or adjustment should be per-

formed by Makita Authorized or Factory Service Centers,

always using Makita replacement parts.
