3.
Loosen the three screws which secure the driver guide
a
half
turn.
4.
Turn
the adjusting bolt
until
the desired depth
of
nailing can be obtained. The adjusting bolt
moves 0.7 mm
(1
/32")
per
turn.
5.
Tighten the three screws while holding the driver guide
so
that the projection of the center
plate contacts the adjusting bolt.
6.
If
nails are driven too deep even when the driver guide is set
at
the lowest position, decrease
the air pressure.
If
nails cannot be driven deep enough even when the driver guide is set at the
highest position, increase the
air
pressure.

Nose
adapter
CAUTION
:
Always lock the trigger and disconnect the hose before installing or removing the nose adapter.
To prevent the workpiece from being damaged or
scratched, attach the nose adapter to the end of the
driver guide.
When
not
using
it,
store
it
in
either storage cavity
in
the inlet cap.
Selecting compressor
The air compressor must comply with the require-
ments of ANSI
B19.3
-
1981.
Select
a
compressor that has ample pressure and air
output to assure cost-efficient operation. The graph
shows the relation between
nailing
frequency, appli-
cable pressure and compressor
air
output. Thus, for ex-
ample,
if
nailing takes place
at
a
rate of approximately
50
times per minute
at
a
compression of
6
kgf/cm2
G
(85
PSIG),
a
compressor with an
air
output over
29
literdminute is required. Pressure regulators must be
used to limit air pressure to the rated pressure of the
I
Storage
cavity
Hose
tool where
air
supply pressure exceeds the tool's rated pressure. Failure to do
so
may result
in
serious
injury
to tool operator
or
persons
in
the vicinity.
Selecting
air
hose
Use
an
air
hose as large and as short
as
possible to assure continuous, efficient nailing operation.
An air hose with an internal diameter of over
6.5
mm
(1/4")
and a length of less
than
20
m
(6.6
ft.)
is recommended. Air supply hoses shall have
a minimum
working pressure rating of
10.7
kgf/cm2
G
(150
PSIG)
or
150
percent of the maximum pressure produced
in
the system
whichever is higher.
CAUTION
:
Low
air
output of the compressor, or
a
long or smaller diameter
air
hose
in
relation to-the
nail-
ing
frequency
may
cause
a
decrease
in
the driving capability of the tool.
