Adjusting depth
of
nailing
CAUTION:
Always lock the trigger and disconnect the hose before adjusting the depth of nailing.
To
adjust the depth of nailing, turn the adjuster
so
that
the arrow above the adjuster will point
to
the number
indicated on the adjuster. The depth of nailing is the
deepest when the arrow points
to
the number
1.
It
will
become shallower as the arrow points to higher
number. The depth can be changed in approx.
1.0
mm
(1132”)
increments per graduation. If nails cannot be
driven deep enough even when the arrow points
to
the number
1,
increase the air pressure.
If
nails are
driven too deep even when the arrow points
to
the
number
8,
decrease the air pressure. Generally speak-
ing, the
tool
service life will be longer when the tool
is
used with lower air pressure and the adjuster set
to
a
lower number.
Connecting air hose
Lock the trigger. Slip the air socket of the air hose onto
the air fitting on the nailer. Be sure that the air socket
locks firmly into position when installed onto the air
fitting. A hose coupling must be installed on or near
the tool in such a way that the pressure reservoir will
discharge at the time the air supply coupling is dis-
connected.
