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) Grip the nail guide and knob with finger.

Press the knob down and swing the nail guide open.

And open the magazine cover. (Fig. 1)

(2) Adjust the position of the plate according to the nail

length.

The nail will not feed smoothly if the nail holder is

not correctly adjusted. (Fig. 2)

1 Turn the nail holder about 90 degrees

counterclockwise.

2 Slide in vertical direction possible.

Lift or lower the nail holder to accept different

length nails.

3 Adjust the plate to the nail length reference points

on the magazine cover and turn the nail holder 90

degrees clockwise until you hear "click".

(3) Place the nail coil into the magazine.

Uncoil enough nails to reach the driving hole. (Fig. 3)

(4) 1 Uncoil enough nails to reach the driving hole.

2 Insert the first nail into the driving hole and the

second nail between the two pawls of the feeder.

3 Fit the nail heads in the guide slot.

4 Pulling the nails to the right, swing the nail guide

closed. (Fig. 4)

(5) Close the magazine cover first and swing the nail

guide closed. (Fig. 5)

(6) Lock the knob correctly.

NOTE:

⅜ Be careful not to deform the collated wires and not to

disengage the nails with the guide surface.

Otherwise, the nail guide will not close correctly.

CAUTION:

⅜ To prevent unitentional operation, never touch the

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

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

toward any part of a person.

NOTE:

⅜ Before loading the nails in the magazine, position the

nail holder according to the length of the nail. If the

nail holder position is not adjusted, the nail jam. If

the cover is forcibly closed without adjusting the

position of the nail holder, the nail holder may be

damaged.

HOW TO USE THE NAILER

CAUTIONS:

⅜ Never use the head or body of this device as a

hammer.

⅜ Take precautions to ensure the safety of persons in

the vicinity during operation.

1. Nailing procedures

(1) Intermittent nailing

Depress the nail outlet onto the desired point; then

pull the trigger to drive a nail in a single shot. (See

Fig. 6)

CAUTION:

⅜ This tool will bounce and shoot several nails instead

of just one in rapid succession when strongly pressed

flush against a surface or when using on hard

materials. In such cases, fire the nails by squeezing

and quickly releasing the trigger.

(2) Push lever

When depressing the nail outlet, be sure to fully lift

the push lever (see Fig. 6) to release the safety lock.

Thus, nails cannot be driven without releasing the

safety lock even though the trigger is pulled.

(3) Continuous nailing

First, pull the trigger. Then depress the devise onto

the desired position to automatically drive nails. (See

Fig. 7).

CAUTION:

Exercise care when nailing corners of lumber. When

continuous nailing corners of lumber, a nail may go

astray or break through the corner.

NOTES:

⅜ Precautions on no-load operation

Sometimes nailing will continue after driving in all

nails previously contained in the magazine.

This is termed “no-load operation”. Such operation

may deteriorate the bumper, magazine, and nail

feeder.

To avoid no-load operation, occasionally confirm the

amount of remaining nails. On the other hand, all nails

should be removed after using this nailer.

⅜ After completing operation, put into the body about

2cc oil through the hose joint to protect the tool from

rust.

⅜ Under low temperature conditions, the machine

sometimes does not operate correctly. Always operate

the machine at the appropriate ambient temperature.

2. How to adjust the nailing depth

To assure that each nail penetrates to the same depth,

be sure that:

(1) the air pressure to the Nailer remains constant

(regulator is installed and working properly), and

(2) the Nailer is always held firmly against the workpiece.

If nails are driven too deep or shallow into the

workpiece, adjust the nailing depth in the following

order.

1 Disconnect air hose from nailer.

2 If nails are driven too deep, turn the adjuster to

the shallow side.

If nails are driven too shallow, turn the adjuster to

the deep side.

3 Stop turning the adjuster when a suitable position

is reached for a nailing test.

4 Connect the air hose.

Always wear eye protection.

Perform a nailing test.

5 Disconnect air hose from nailer.

6 Choose a suitable position for the adjuster. (Fig.

CAUTIONS:

⅜ Before adjustment, always disconnect the hose and

release compressed air in the power tool.

⅜ During adjustment always keep your finger off the

trigger.

⅜ During adjustment make sure that no part of the body,

hands, or legs is ever in front of the nail outlet.

NOTE:

⅜ Please use the minimum air pressure that is sufficient

to drive the nails to a suitable depth. If an overly high

pressure is used, the life of the piston damper etc.

will be shortened.
