The adjuster can be fiexed each at 1/4 rotation.
The adjuster moves approximately 0.25mm per 1/4
rotation.
3 Stop turning the adjuster when a suitable position is
reached for a nailing test.
4 Connect the air hose.
ALWAYS WEAR EYE PROTECTOR.
Perform a nailing test.
5 DISCONNECT AIR HOSE FROM NAILER.
6 Choose a suitable position for the adjuster.
NOTE:
The nail-driving depth can also be adjusted by changing
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 life of this nailer.

INSPECTION AND MAINTENANCE

CAUTION:
Be sure to disconnect the hose during cleaning
jams, inspection, maintenance and cleaning.
1. Countermeasure for nail jamming

guide, insert a rod into the outlet and tap the rod with
a hammer. (Fig. 11).
(2) Remove the jammed nail with slotted screwdriver.
(Fig. 12)
Nail
(3) Cut off the defective part of the steel wire which links
the nails with cutting nippers, correct the deformation,
then load the nail roll in the magazine.
(4) In case of frequent jams, consult the Authorized Service
Center from which you bought this machine.
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
equipment with loose screws untightened will incur
a hazard.
3. Protection against dirt
Remove dirt from the inlet port and interior of the
hose.
Use only clean oil to protect the air intake port and
sliding part against clogging or damage.
4. Inspecting the feeders
(1) Occasionally clean the knob sliding part and then
apply the recommended oil. (See Fig. 13)
