(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 staples

(1)Pull the staple feeder backward and attach it securely to a groove of the magazine. (see Fig. 2)

(2)Place the staple strip over the magazine.

Make sure that the staple strip slides freely on the magazine. (see Fig. 3)

(3)Pull the staple feeder backward. Then, detach it from the groove of magazine and softly bring the staple

back as if it were being gently pushed, avoiding any impact. (see Fig. 4)

The stapler is now ready to operate.

CAUTION:

If the staple feeder is released all of a sudden, it can return abruptly, causing deformation and/or scatter, eventually ending up in clogged staples.

Be absolutely sure to bring back the staple feeder, avoiding any impact.

HOW TO USE THE STAPLER

CAUTIONS:

￿Never use the head or body of this device as a hammer.

￿Take precautions to ensure the safety of persons in

the vicinity during operation.

1.Stapling procedures

(1) Intermittent stapling

Depress the staple outlet onto the desired point; then pull the trigger to drive a staple in a single shot. (See Fig. 5)

CAUTION:

￿ This tool will bounce and shoot several staples 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 staples by squeezing and quickly releasing the trigger.

(2) Push lever

When depressing the staple outlet, be sure to fully lift the push lever (see Fig. 5) to release the safety lock. Thus, staples cannot be driven without releasing the safety lock even though the trigger is pulled.

(3) Continuous stapling

First, pull the trigger. Then depress the devise onto the desired position to automatically drive staples. (See Fig. 6).

CAUTION:

Exercise care when stapling corners of lumber. When continuous stapling corners of lumber, a staple may go astray or break through the corner.

NOTES:

￿ Precautions on no-load operation

Sometimes stapling will continue after driving in all staples previously contained in the magazine.

This is termed “no-load operation”. Such operation may deteriorate the bumper, magazine, and staple feeder.

To avoid no-load operation, occasionally confirm the amount of remaining staples. On the other hand, all staples should be removed after using this stapler.

￿ After completing operation, put into the body about 2cc oil through the hose joint to protect the tool from rust.

￿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 stapling depth

To assure that each staple penetrates to the same depth, be sure that:

(1)the air pressure to the stapler remains constant (regulator is installed and working properly), and

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

If staples are driven too deep or shallow into the workpiece, adjust the stapling in the following order.

CAUTIONS:

￿Before adjustment, always disconnect the hose and release compressed air in the power tool.

￿During adjustment always keep your finger off the trigger.

￿During adjustment make sure that no part of the body, hands, or legs is ever in front of the staple outlet.

Please carry out adjustments in the following order. (See Fig. 7)

To adjust the driven-in depth of a staple, loosen the screw that secures a push lever piece.

If the staple is driven in deeply, adjust the push lever piece to ”down”, and if it’s driven in shallowly, adjust the push lever piece to “up”.

Tighten the screw to fasten the push lever piece.

NOTE:

￿Please use the minimum air pressure that is sufficient to drive the staples to a suitable depth. If an overly high pressure is used, the life of the piston damper etc. will be shortened.

INSPECTION AND MAINTENANCE

CAUTION:

Be sure to disconnect the hose during cleaning jams, inspection, maintenance and cleaning.

1.Countermeasure for staple jamming

(1) Remove all staples.

(2) Release the lock lever and open the blade guide. (see Fig. 8)

(3) Remove the jammed staple with a slotted-head screwdriver. (see Fig. 9)

(4) Close the blade guide and latch.

(5) In case of frequent jam, contact a Hitachi authorized service center.

2.Inspection and maintenance Periodically inspect the device.

(1)Remove the four hexagon socket hd. bolts securing the exhaust cover and remove the exhaust cover. Then, cylinder, piston, and other parts can be removed in respective assembly groups.

Wipe the drive bit, the piston sliding part and the body interior with a cloth to remove deposited dirt.

(2)Confirm that the piston damper offers normal operation. A damaged piston damper may cause damage to other component parts.

(3)Carefully check the O-ring for wear while disassembling. A worn or damaged O-ring may deteriorate overall performance. Replace a worn or damaged O-ring with new one.

(4)Prior to reassembling the device, apply grease (Attolub No. 2 Grease) to the O-ring. Also, lubricate the device with the recommended oil.
