Each planer blade must be assembled and aligned centered
to the planer base plate 8. Afterwards, tighten the three fas-
tening screws 11 with the Torx key 10, ensuring the correct
tightening sequence () on the clamping jaw 12.
Note: Before starting operation, check the fastening screws
11 for tight seating. Rotate the blade head 13 manually and
ensure that the planer blades do not graze.
Replacing Carbide Blades (TC)
 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 planer blades (TC) have two cutting edges, which
can be reversed. When both cutting edges are dull, the planer
blades 20 must be replaced. Carbide blades (TC) may not be
resharpened.
Disassembling the Planer Blade(s) (see figures G – H)
– To reverse or replace the planer blades, rotate the blade
drum 13 until the clamping jaw 12 is parallel to the planer
base plate 8.
– Loosen the three fastening screws 11 with the Torx key 10
by approx. 1 – 2 turns. The clamping jaw 12 does not have
to be removed.
– Rotate the blade drum a little and push the planer blade 20
sidewards out of the blade drum 13 with a piece of wood.
– Turn the blade drum by 180° and disassemble the 2nd
planer blade.
Assembling the Planer Blade(s) (see figures I – J)
The guide groove of the planer blade always ensures continu-
ous height adjustment when replacing or reversing it.
If required, clean the blade seat in the blade drum 13 and the
planer blade 20.
When assembling the planer blade, ensure that it is seated
properly in the blade holder of the blade drum 13.
Each planer blade must be assembled and aligned centered
to the planer base plate 8. Afterwards, tighten the three fas-
tening screws 11 with the Torx key 10, ensuring the correct
tightening sequence () on the clamping jaw 12.
Note: Before starting operation, check the fastening screws
11 for tight seating. Rotate the blade head 13 manually and
ensure that the planer blades do not graze.

planers equipped with HSS planer blades can be converted to
TC planer blades.
– Loosen and remove the clamping jaw 12.
– Slide the planer-blade retainer 16 together with the planer
blade 15 out of the guide groove 14 of the blade drum 13.
– Insert the conversion kit 2 607 001 399 into the guide
groove 14.
– Reattach the clamping jaw 12 and screw in the fastening
screws 11, but do not tighten them yet.

blade seat.
– Each planer blade must be assembled and aligned cen-
tered to the planer base plate 8. Afterwards, tighten the
three fastening screws 11 with the Torx key 10, ensuring
the correct tightening sequence () on the clamping
jaw 12.
Converting from TC to HSS
With the conversion kit 2 607 001 398 (see accessories),
planers equipped with TC planer blades can be converted to
HSS planer blades.
– Unscrew the 3 fastening screws 11 with the Torx key 10
and remove the clamping jaw 12.
– Slide the planer-blade retainer 16 together with the planer
blade 15 out of the guide groove 14 of the blade drum 13.
– Insert the conversion kit 2 607 001 398 into the guide
groove 14 and align it centered to the planer base plate
8.
– Reattach the clamping jaw 12 and tighten the three fasten-
ing screws 11 with the Torx key 10. Ensure the correct
tightening sequence () on the clamping jaw 12.
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 suitable
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 mate-
rials to be worked.
Clean the chip ejector 3 regularly. Clean a clogged chip ejec-
tor using a suitable tool, e. g. a piece of wood, compressed
air, etc.
 Do not reach into the chip 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.
