Operation
Starting Operation
Inserting the Battery
Use only original Bosch lithium-ion batteries with the
u
voltage stated on the type plate of your power tool.
Using other batteries can lead to injuries and pose a fire
hazard.
Note: The use of batteries unsuitable for your power tool can
lead to malfunctions or damage to the power tool.
Slide the charged battery (18) into the base of the power
tool from the front. Press the battery fully into the base until
the battery is securely locked.
Setting the Volume Flow Rate
The volume flow rate of the switched on caulking gun can be
variably adjusted, depending on how far the On/Off switch
(13) is pressed.
You can use the volume flow rate limiter (11) to preset the
maximum feed rate of the rack (7). High values mean a high
rack rate, while small values mean a low rack rate.
