All fittings, connecting lines and hoses must be dimensioned for the pres-
sure and the required air volume.
Avoid restrictions in the air supply, e.g., from pinching, kinking, or
stretching!
Connecting the Air Supply to the Pneumatic Tool
– Empty the magazine
8
.
(See “Emptying the Magazine”, page 19)
For the following worksteps, a fastener can be discharged when interi-
or parts of the pneumatic tool are not in the starting position due to re-
pairs, maintenance or transport.
– Connect the air connector
6
with a supply-air hose
13
equipped with an
air-connection coupling
12
.
– Check the proper function by placing the outlet
11
or the rubber work-
piece protector
1
of the pneumatic tool onto a piece of scrap wood or
wood material, and discharging once or twice.
Loading the Magazine (see figures B1
–
B2)
Disconnect the air supply before making any adjust-
ments, changing accessories, or placing the pneumatic
tool aside.
This safety measure prevents accidental start-
ing of the pneumatic tool.
f
Use only original Bosch accessories (see “Technical Data”).
The
precision parts of the pneumatic tool such as the magazine, the outlet
and the shot duct are matched to Bosch staples, nails and brads. Other
manufacturers use other steel qualities and sizes.
Using fasteners not permitted, can damage the pneumatic tool and
cause injuries.
While loading the magazine, hold the pneumatic tool in such a manner
that the outlet
11
is not pointed at your own body or at other persons.
– Pull back the magazine slider
7
until it engages at the rear.
Note:
The magazine slider must slide back with only low force (finger-
pressure). A tight-running magazine slider causes the nails to be driven in
at an incorrect angle.
– Clean and lubricate the magazine slider
7
as required and make sure
that the magazine
8
is not dirty/soiled.
– Insert a fitting nail strip
14
.
Do not use nail strips with less than 5 nails. Do not insert more than 2
nail strips. Make sure that the heads of the nails do not overlap.
GSN 90-34 DK:
With this pneumatic tool, a lock function of the magazine
slider prevents the last nails from being discharged. Approx. 7 nails re-
main in the magazine.
– Completely pull back the magazine slider
7
once more to free the lock.
– Carefully guide the magazine slider to the front until it touches the nail
strip.
Make sure that the magazine slider is slid beyond the head of the last
nail.
Note:
Do not let the magazine slider snap back without guiding it. Other-
wise, the magazine slider could become damaged, and there is danger of
your fingers being caught or pinched.
Operation
Actuation systems
The pneumatic tool can be operated with two different actuations sys-
tems:
–
Single actuation with safety run
With this actuation system, the discharge lock-off
2
must first be firmly
pressed against the workpiece. A fastener is not discharged until the
trigger
10
is pulled.
Afterwards, further discharging procedures can only be actuated,
when the trigger and the discharge lock-off have first been set back to
the starting position.
–
Contact actuation
With this actuation system, the trigger
10
must be pulled first. A fasten-
er is always discharged when the discharge lock-off
2
is firmly pressed
against the workpiece while the trigger is pressed.
This enables a higher working speed to be achieved.
The actuation system is set via the selector switch
9
.
Starting Operation
Disconnect the air supply before making any adjust-
ments, changing accessories, or placing the pneumatic
tool aside.
This safety measure prevents accidental start-
ing of the pneumatic tool.
Working with Single Actuation (see figure C)
– Press selector switch
9
inward and at the same time pivot it to the bot-
tom position until it engages.
The actuation system “single actuation” is set.
– Release the selector switch
9
again.
– Firmly position the outlet
11
or the rubber workpiece protector
1
on
the workpiece until discharge lock-off
2
is pressed in completely.
– Afterwards, briefly press trigger
10
and release again.
A nail is discharged.
– Allow the pneumatic tool to bounce back from the workpiece.
– For another driving procedure, completely lift the pneumatic tool from
the workpiece and position it firmly at the next desired location.
Working with Contact Actuation (see figure D)
– Press selector switch
9
inward and at the same time pivot it to the up-
per position until it engages.
The actuation system “contact actuation” is
set.
– Release the selector switch
9
again.
– Press and hold the trigger
10
.
– Firmly position the outlet
11
or the rubber workpiece protector
1
on
the workpiece until discharge lock-off
2
is pressed in completely.
A nail is discharged.
– Allow the pneumatic tool to bounce back from the workpiece.
– For another driving procedure, completely lift the pneumatic tool from
the workpiece and position it firmly at the next desired location.
– Move the pneumatic tool uniformly over the workpiece by lifting it off
and applying it again.
Each time when applying the pneumatic tool while the discharge lock-
off is pressed in, a nail will be discharged.
– As soon as the desired amount of nails have been driven in, release trig-
ger
10
again.
Working Advice
Disconnect the air supply before making any adjust-
ments, changing accessories, or placing the pneumatic
tool aside.
This safety measure prevents accidental start-
ing of the pneumatic tool.
