Noise/Vibration Information
Typically the A-weighted noise levels of the prod-
uct are: Sound pressure level 82 dB(A); Sound
power level 93 dB(A). Uncertainty K =3 dB.
Wear hearing protection!
Vibration total values (triax vector sum) deter-
mined according to EN 60745:
Vibration emission value a
h
2
ty K = 1.5 m/s .
The vibration emission level given
WARNING
in this information sheet has
been measured in accordance with a standard-
ised test given in EN 60745 and may be used to
compare one tool with another.
The vibration emission level will vary because of
the ways in which a power tool can be used and
may increase above the level given in this infor-
mation sheet. This could lead to a significant un-
derestimate of exposure when the tool is used
regularly in such a way.
Note: To be accurate, an estimation of the level
of exposure to vibration experienced during a giv-
en period of work should also take into account
the times when the tool is switched off and when
it is running but not actually doing the job. This
may significantly reduce the exposure level over
the total working period.
Assembly
Before any work on the machine itself, pull
the mains plug.
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 14 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 14, rotate
the blade drum 11 until it is parallel to the planer
base plate 9.

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 12 and the planer blade 14.
When assembling the planer blade, ensure that it
is seated properly in the blade holder of the
clamping element 12 and aligned flush at the side
edge of the rear planer base plate 9. Afterwards
tighten the 2 fastening screws 13 again with the
Allen key 15.
Note: Before restarting, check if the fastening
screws 13 are tightened well. Rotate the blade
drum 11 by hand and ensure that the planer
blade does not graze.
Dust/Chip Extraction
Clean the chip ejector 3 regularly. Use a suitable
tool (e.g., a piece of wood, compressed air, etc.)
to clean a clogged chip ejector.
To ensure optimum extraction of dust/chips, al-
ways work with external dust extraction or a
chip/dust bag.
External Dust Extraction (see figure C)
An extraction hose ( Ø 35 mm) 16 (accessory),
can be attached on either side of the chip ejec-
tor.
Loosen the two fastening screws 13 with the
Allen key 15 by approx. 1 – 2 turns.
If necessary, loosen the clamping element 12
by giving it a light blow with a suitable tool
(e.g. a wooden wedge).
Push the planer blade 14 sidewards out of
the blade drum 11 with a piece of wood.
Do not reach into the saw dust ejector with
your hands. They could be injured by rotating
parts.
