Working Advice
Before starting work, always check that the safety and actu-
ation devices are functioning correctly and that all screws
and nuts are tightly seated.
If a power tool is defective or not functioning properly, dis-
connect it immediately from the power supply and contact
an authorised Bosch after-sales service centre.
Do not perform any incorrect manipulations on the power
tool. Do not disassemble or block any components of the
power tool, such as the discharge lock-off.
Do not carry out "emergency repairs" with unsuitable means.
The power tool is to be maintained regularly and properly.
Avoid any tampering and damage to the power tool, e. g.
from:
– Imprinting or engraving,
– Retrofitting measures not approved by the manufacturer,
– Guiding along templates manufactured of hard material,
e.g. steel,
– Dropping on or sliding over the floor,
– Using as a hammer,
– Applying any kind of force.
Make sure to check whatever is below or behind your work-
piece. Do not shoot nails into walls, ceilings or floors, when
persons are behind them. The nails can burst through the
workpiece and injure someone.
Do not shoot a nail onto an already driven-in one. This could
cause the nail to deform, the nails could become jammed or
the power tool could move in an uncontrolled manner.
When the power tool is used under cold ambient conditions,
the first nails will be driven in slower than usual. Once the
power tool has warmed up during working, normal operating
speed will be regained.
Avoid pulling the trigger when the magazine is empty to min-
imise wear on the firing pin.
For longer work breaks or after finishing work, switch off the
power tool, remove the battery and empty the magazine if
possible.

Emptying the magazine (see figures C1–C2)
– Press the switch (13) to open the magazine. The
magazine slider extends.
– Rotate the power tool so that the nail strip slides out in
the magazine.
– Then carefully guide the magazine slider forwards to the
beginning of the magazine (14).
Adjusting the depth stop (see figure D)
The driving depth of the nails can be set with the
thumbwheel (5).
– Empty the magazine (14).
– Nails are driven in too deep: To reduce
the driving depth, turn the
thumbwheel (5) in the "–" direction.
– Nails are not driven in deep enough: To
increase the driving depth, turn the
thumbwheel (5) in the "+" direction.
You can check the depth stop adjustment on the depth stop
adjustment display (4).
– Refill the magazine.
– Test the new driving depth on a test workpiece.
Repeat the worksteps as required.
Clearing jams (see figures E1–E2)
Single nails can become jammed in the shot duct. If this
should occur frequently, please contact an authorised Bosch
after-sales service centre.
Note: If the driver blade does not return after clearing a jam,
please contact an authorised Bosch after-sales service
centre.
– Release the trigger (6).
– Switch the power tool off and remove the battery (11).
– Empty the magazine (14).
– Press the clamping lever (3) down so that the shot duct
opens.

quired.
