An estimation of the level of exposure to vibration should also
take into account the times when the tool is switched off or
when it is running but not actually doing the job. This may sig-
nificantly reduce the exposure level over the total working pe-
riod.
Identify additional safety measures to protect the operator
from the effects of vibration such as: maintain the tool and the
accessories, keep the hands warm, organisation of work pat-
terns.

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 plan-
er blades.
Use only original Bosch carbide blades (TC).
The carbide blade (TC) has 2 cutting edges and can be re-
versed. When both cutting edges are dull, the planer blade 12
must be replaced. The carbide blade (TC) may not be resharp-
ened.
Disassembling the Planer Blade(s) (see figure A)
To reverse or replace the planer blade 12, rotate the blade
drum 9 until it is parallel to the planer base plate 6.
Loosen the two fastening screws 11 with the Allen key
13 by approx. 1 – 2 turns.
If necessary, loosen the clamping element 10 by giving it
a light blow with a suitable tool (e.g. a wooden wedge).
Push the planer blade 12 sidewards out of the blade
drum 9 with a piece of wood.
Assembling the Planer Blade(s) (see figure B)
The guide groove of the planer blade always ensures continu-
ous height adjustment when replacing or reversing it.
Bosch Power Tools
If required, clean the blade seat in the clamping element 10
and the planer blade 12.
When assembling the planer blade, ensure that it is seated
properly in the blade holder of the clamping element 10 and
aligned flush at the side edge of the rear planer base plate 6.
Afterwards tighten the 2 fastening screws 11 again with the
Allen key 13.
Note: Before restarting, check if the fastening screws 11 are
tightened well. Rotate the blade drum 9 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. Touching or breathing-in the dusts can cause
allergic reactions and/or lead to respiratory infections of
the user or bystanders.
Certain dusts, such as oak or beech dust, are considered
as carcinogenic, especially in connection with wood-treat-
ment additives (chromate, wood preservative). Materials
containing asbestos may only be worked by specialists.
– As far as possible, use a dust extraction system suita-
ble for the material.
– 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
materials to be worked.
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.
Do not reach into the saw dust ejector with your hands.
They could be injured by rotating parts.
To ensure optimum extraction of dust/chips, always work
with external dust extraction or a chip/dust bag.
External Dust Extraction (see figure C)
Firmly attach the extraction adapter 15 to the sawdust ejec-
tor 3. An extraction hose with a diameter of 35 mm can be
connected to the extraction adapter 15.
Connect the vacuum hose 14 to a vacuum cleaner (accesso-
ry). An overview for connecting to various vacuum cleaners
can be found at the end of this manual.
The vacuum cleaner must be suitable for the material being
worked.
When vacuuming dry dust that is especially detrimental to
health or carcinogenic, use a special vacuum cleaner.
Integrated Dust Extraction (see figure C)
A chip/dust bag (accessory) 16 can be used for smaller jobs.
Insert the sleeve of the chip/dust bag firmly into the chip ejec-
tor 3. Empty the chip/dust bag 16 at regulary intervals to
maintain optimum dust collection.
