(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:
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. 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:
⅜ 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:
⅜ 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.
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 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:
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 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:
⅜ 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.
