sure that the nail outlet is not facing downward and
that body parts or other persons are not in the path of
the nail outlet.
Adjusting the adjuster (Fig. 11)
Carry out test driving. If the nails are too deep, turn
the adjuster to the shallow side (
If the nail depth is too shallow, turn the adjuster
to the deep side (
The ajuster moves 0.5 mm every time it is rotated
with a click.
Shallow
Flush Too deep
NOTES:
When adjusting the adjuster, it does not rotate more
than 3 mm from the deepest point where a nail goes
down. Do not rotate the adjuster by force beyond that
point.
The nail-driving depth can also be adjusted by chang-
ing the air pressure used. Carry this out together with
movement of the adjuster. Using a high air pressure
that does not match the nail-driving resistance will
shorten the service life of this nailer.
3. Changing the exhaust direction.
The direction of the exhaust vent can be changed
within 360° by turning the head ring. (Fig. 13)

INSPECTION AND MAINTENANCE

CAUTION:
Be sure to disconnect the hose during cleaning
jams, inspection, maintenance and cleaning.
1. Countermeasure for nail jamming
(1) Remove the nail roll from the magazine, open the nail
guide, insert a rod into the nail outlet and tap the rod
with a hammer. (Fig. 14)
(2) Remove the jammed nail with slotted-head screw-
driver. (Fig. 15)

(3) Cut off the defective part of the steel wire which links
the nails with cutting nippers, correct the deforma-
tion, then load the nail roll in the magazine.
(4) In case of frequent jam, consult the Authorized Serv-
ice Center from which you bought this nailer.
2. Check on mounting screws for each part
At regular intervals check every part for loose
mounting screws and whether or not there are any
air leaks. Retighten any loose screws. Operating the
nailer with loose screws untightened will incur a
hazard.
3. Inspecting the push lever
Check if the push lever can slide smoothly. (Fig. 16)
Clean up the sliding area of the push lever and use the
provided oil for lubrication from time to time. Lubri-
cation enables smooth sliding and simultaneously
serves to prevent the formation of rust.
