Assembly
Before any work on the machine (e. g. main-
tenance, changing the tool, etc.) as well as
during its transport and storage, lock the
On/Off switch in the off position. There is
danger of injury when the On/Off switch is
unintentionally actuated.
Battery Charging (see figure D)
A battery that is new or has not been used for a
longer period does not develop its full capacity
until after approx. 5 charging/discharging cy-
cles.
To remove the battery 7, press the unlocking
buttons 8 and pull the battery out of the ma-
chine to the rear. Do not exert any force.
The Allen key 16 required for replacement of the
planer blade is located inside the machine and
should always be stored there.
The battery is equipped with a NTC temperature
control which allows charging only within a tem-
perature range of between 0 °C and 45 °C. A
long battery service life is achieved in this man-
ner.
A significantly reduced working period after
charging indicates that the battery is used and
must be replaced.
Observe the notes for disposal.

Changing the Tool

Be cautious when replacing the planer
blades. Do not grasp the planer blades by
the cutting edges. Possible danger of injury
due to the sharp cutting edges of the planer
blades.
Use only original Bosch carbide blades (TC).
The carbide blade (TC) has 2 cutting edges and
can be reversed. When both cutting edges are
dull, the planer blade 15 must be replaced. The
carbide blade (TC) may not be resharpened.
Disassembling the Planer Blade(s)
(see figure A)
To reverse or replace the planer blade 15, rotate
the blade drum 12 until it is parallel to the plan-
er base plate 10.
Bosch Power Tools
Loosen the two fastening screws 14 with
the Allen key 16 by approx. 1 – 2 turns.
If necessary, loosen the clamping element
13 by giving it a light blow with a suitable
tool (e.g. a wooden wedge).
Push the planer blade 15 sidewards out of
the blade drum 12 with a piece of wood.
Assembling the Planer Blade(s) (see figure B)
The guide groove of the planer blade always en-
sures continuous height adjustment when re-
placing or reversing it.
If required, clean the blade seat in the clamping
element 13 and the planer blade 15.
When assembling the planer blade, ensure that
it is seated properly in the blade holder of the
clamping element 13 and aligned flush at the
side edge of the rear planer base plate 10. After-
wards tighten the 2 fastening screws 14 again
with the Allen key 16.
Note: Before restarting, check if the fastening
screws 14 are tightened well. Rotate the blade
drum 12 by hand and ensure that the planer
blade does not graze.

Dust/Chip Extraction

Dusts from materials such as lead-containing
coatings, some wood types, minerals and
metal can be harmful to one's health. Touch-
ing or breathing-in the dusts can cause aller-
gic reactions and/or lead to respiratory infec-
tions of the user or bystanders.
Certain dusts, such as oak or beech dust, are
considered as carcinogenic, especially in
connection with wood-treatment additives
(chromate, wood preservative). Materials
containing asbestos may only be worked by
specialists.
– Use dust extraction whenever possible.
– Provide for good ventilation of the work-
ing place.
– It is recommended to wear a P2 filter-
class respirator.
Observe the relevant regulations in your
country for the materials to be worked.
