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 a t 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 t o 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 a t
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 t o 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 t o do
so
may result
in
serious injury to tool operator or persons in the vicinity.
Selecting air hose
Use
a n air
hose as large and as short
as
possible t o assure continuous, efficient nailing operation.
An air hose with an internal diameter of over 6.5
m m (1/4")
and a length of less t h a n 20
m
(6.6 f t . ) 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.
