(2) Selecting hardened nails for steel plates
CAUTION
○ Use C-beam steel with a thickness of 3.2 mm or less.
○ Use hardened nails designed for use with steel plating.
○ Place the nailer vertically over the location into which
the nail is to be driven.
○ When galvanized steel or other metal plates are to be
attached directly onto C-beam steel, make sure they
are 0.7 mm or less in thickness.
Also, make sure that nails designed for use with steel
plating with a length of 27 mm are used.
○ Do not use the nailer on roofs or ceilings.
○ Make sure that the thickness of the hardened nails
designed for use with steel plating are of the correct
thickness for the C-beam steel.
If the nail is longer than the thickness of the material, it
may result in it not being driven into C-shaped steel or in it
bending, which could lead to injury.
Select the appropriate nail length in accordance with the
illustration shown in the next section.

NOTE
○ Holding power will be greatly decreased if nails are
driven too hard into steel plating, adjust the driving
depth of the nail by the adjuster.
○ There are cases in which the nails will not be driven
in suffi ciently depending on a combination of the
hardness and thickness of the C-beam or material.

3. Adjusting the nail-driving depth
CAUTION
When making adjustments, be sure remove your fi nger
from the trigger. When making adjustments, be sure
that the nail outlet is not facing downward and that
body parts or other people are not in the path of the nail
outlet.
○ Adjusting the adjuster (Fig. 13)
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
mark) (See Fig. 13, 14).
deep side (
Depth is changed 1 mm with each rotation of the
adjuster.
NOTE
○ 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 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.
4. Cutting off the sheet
Tear off the output sheet in the direction of the arrow
when using the sheet collated nails (Fig. 15).
5. How to use nose cap
CAUTION
Remove the hose from the nailer and release the
compressed air before installing or removing the nose
cap to prevent accidental nail ejection.
○ Attach the nose cap on the tip of the push lever when
you wish to protect the surface of wood, etc., from
scratches.
(1) Attaching and detaching nose cap
The nose cap can be attached by simply pressing it into
the push lever. (Fig. 16)
For removal, insert a thin rod such as a screw driver into
the gap on the back of the push lever, and then pull it
out.
(2) Safekeeping of nose cap
Put the removed nose cap in a space above the
magazine for safekeeping. (Fig. 17)
