Changing the Tool
The hex tool holder enables you to change the application
tool easily and conveniently without the use of additional
tools.
The dust protection cap (1) largely prevents the penetration
of drilling dust into the tool holder during operation. When
inserting the tool, make sure that the dust protection cap (1)
does not become damaged.
Replace a damaged dust protection cap immediately.
u
It is recommended that you have use an after-sales
service for this.
Inserting the application tool (see figure A)
– Clean and lightly grease the shank of the application tool.
– Push the locking sleeve (2) back and insert the applica-
tion tool by turning it into the tool holder. Release the
locking sleeve (2) to lock the application tool.
– Check the latching by pulling the tool.
Removing the application tool (see figure B)
– Push the locking sleeve (2) back and remove the applica-
tion tool.

Dust/Chip Extraction

Dust from materials such as lead-containing coatings, some
wood types, minerals and metal can be harmful to one's
health. Touching or breathing-in the dust can cause allergic
reactions and/or lead to respiratory infections of the user or
bystanders.
Certain dust, such as oak or beech dust, is considered carci-
nogenic, especially in connection with wood-treatment ad-
ditives (chromate, wood preservative). Materials containing
asbestos may only be worked by specialists.
– Provide for good ventilation of the working place.
– It is recommended to wear a P2 filter-class respirator.
Observe the relevant regulations in your country for the ma-
terials to be worked.
Operation

Starting Operation

Pay attention to the mains voltage. The voltage of the
u
power source must match the voltage specified on the
rating plate of the power tool. Power tools marked
230 V can also be operated at 220 V.
Products that are only sold in AUS and NZ: Use a resid-
u
ual current device (RCD) with a nominal residual current
of 30 mA or less.
Switching On and Off
– To start the power tool, press and hold the on/off switch
(4).
– Press the lock-on button (3) to lock the on/off switch (4)
in this position.
– To switch off the power tool, release the on/off switch
(4); or, if the switch is locked with the lock-on button (3),
briefly press the on/off switch (4) and then release it.
Bosch Power Tools
At low temperatures, the power tool will take a certain
amount of time to reach its full impact performance. You can
shorten this warm-up time by tapping the power tool's inser-
ted application tool on the ground once.
Working Advice
Pull the plug out of the socket before carrying out any
u
work on the power tool.
Sharpening Chisels
Only sharp chiselling tools will produce good results, there-
fore sharpen your chiselling tools in good time before use.
This will ensure a long service life for the tools and good
work results.
Re-sharpening
Grind chiselling tools against sanding discs, e.g. aluminium
oxide, under a steady stream of water. Make sure that the
cutting edges show no annealing colours; this will impair the
hardness of the chiselling tools.
To forge a chisel, heat it to 850–1050 °C (pale red to yel-
low).
To harden a chisel, heat it to approx. 900 °C and quench in
oil. Then, leave it in an oven for approx. one hour at 320 °C
(annealing colour: pale blue).

Maintenance and Service

Maintenance and Cleaning

Pull the plug out of the socket before carrying out any
u
work on the power tool.
To ensure safe and efficient operation, always keep
u
the power tool and the ventilation slots clean.
Replace a damaged dust protection cap immediately.
u
It is recommended that you have use an after-sales
service for this.
In order to avoid safety hazards, if the power supply cord
needs to be replaced, this must be done by Bosch or by a
customer service centre that is authorised to repair Bosch
power tools.
Lubrication
The power tool is lubricated with grease and is ready for im-
mediate use.
The lubricating grease should only be changed during main-
tenance or commissioning carried out by an after-sales ser-
vice centre authorised to work with Bosch power tools. It is
crucial that only lubricating grease provided by Bosch is
used.
The lubricating grease must be changed every time the car-
bon brushes are replaced. The old lubricating grease must
be removed before new lubricating grease is applied.
