– With the nail pusher 13 pressed, carefully guide the
magazine slider 12 toward the front until the nail push-
er is over the last nail, thus pushing the nail strip in the
magazine completely to the front.
Note: Do not let the magazine slider snap back without
guiding it. Otherwise, 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 systems:
– 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 5 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 5 must be
pulled first. A fastener is always discharged when the
discharge lock-off 2 is firmly pressed against the work-
piece while the trigger is pressed.
This enables a higher working speed to be achieved.
The actuation system is set via the selector switch 6.

Starting Operation

Working with Single Actuation (see figure C)
– Press selector switch 6 inward and at the same time
pivot it to the bottom position until it engages.
– Firmly position the outlet 15 or the rubber workpiece
protector 1 on the workpiece until discharge lock-off 2
is pressed in completely.

pivot it to the upper position until it engages.
The actuation system "contact ac-

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 dis-
charged.
– As soon as the desired amount of nails have been driv-
en in, release trigger 5 again.

Working Advice

Disconnect the air supply before making any
adjustments, changing accessories, or plac-
ing the pneumatic tool aside. This safety
measure prevents accidental starting of the
pneumatic tool.
Check the proper function of the safety and actuation de-
vices, and the tight seating of all screws and nuts each
time before using.
Disconnect a defective or not properly operating pneu-
matic tool immediately from of the air supply and contact
an authorised service agent for Bosch power tools.
Do not perform any incorrect manipulations on the pneu-
matic tool. Do not disassemble or block any components
of the pneumatic tool, such as the discharge lock-off.
Do not carry out "emergency repairs" with unsuitable
means. The pneumatic tool is to be maintained regularly
and properly (see "Maintenance and Cleaning", page 25).
