Assembly
Connecting the Air Supply
Make sure that the pressure of the compressed-air system is below the
maximum permitted rated pressure of the pneumatic tool. Firstly, set the
air pressure to the lower value of the recommended rated pressure (see
"Technical Data").
When in doubt, check the pressure at the air inlet with a pressure gauge
with the pneumatic tool switched on.
For maximum performance, the values for the supply-air hose 13 (con-
nection thread, maximum operating pressure, inner hose diameter, max-
imum hose length; see "Technical Data") must be observed.
The compressed air supplied should be free of foreign material and mois-
ture to protect the tool from damage, contamination, and the formation of
rust.
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 (see figure A)
– Empty the magazine 6.
(See "Emptying the Magazine", page 18)
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 3 with a supply-air hose 13 equipped with an
air-connection coupling 12.
– Check the proper function by placing the outlet 9 of the pneumatic tool
against a piece of scrap wood or wood material, and discharging once
or twice.
Changing the Trigger (see figures B1
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.
The pneumatic tool can be operated with two different actuation systems.
The actuation system is selected by installing the appropriate trigger.
Symbol Trigger
Trigger 5 (grey)
Trigger 8 (red)
Removing the Trigger
– Pull off rubber ring 14 from locking pin 15.
– Pull locking pin 15 out of the housing.
– Pull the trigger toward the rear bottom out of the housing.
Mounting the Trigger
– Select the matching trigger to the desired actuation system.
Note: When mounting the grey trigger 5, pay attention that actuation le-
ver 16 is in the correct position (see figure B2).
– Slide the trigger into the housing.
Make sure that actuation spring 17 encloses actuation bolt 18 and ex-
erts force against trigger lever 16.
Bosch Power Tools
– Align the trigger mounting holes with those of the housing and slide
– Slide rubber ring 14 onto the groove of locking pin 15.
Loading the Magazine (see figures C1
While loading the magazine, hold the pneumatic tool in such a manner
that the outlet 9 is not pointed at your own body or at other persons.
– Clean and lubricate shot duct 21 as required and make sure that the

The magazine spindle 19 must be adjusted to the length of the nails so
that the nails can be rolled off easily into the outlet.
– Pull the magazine spindle 19 upward and turn the magazine spindle un-

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.
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.

tioned in shot duct 21 and the second in feeder hook 22.
Position the nail heads into guide groove 23.
When inserting the nail role, pay attention not to damage or de-
form the wire winding of the nails. Because of a damaged wire wind-
ing or an incorrectly inserted nail role, it is possible that the magazine
cover can no longer be correctly shut. This leads to a malfunction of the
pneumatic tool.
With this actuation system, the discharge lock-off 10 must first be firm-
ly pressed against the workpiece. A fastener is not discharged until the
trigger 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.
With this actuation system, the trigger must be pulled first. A fastener
is always discharged when the discharge lock-off 10 is firmly pressed
against the workpiece while the trigger is pressed.
This enables a higher working speed to be achieved.
