Note: Before replacing or resharpening the plan-
er blades, remove the HSS planer-blade retainer
16 by loosening the fastening screws 17.
Resharpening HSS Planer Blades (see figure D)
Worn or dull HSS planer blades can be resharp-
ened with the sharpening device 18 (accessory)
and a commercially available whetstone.
Insert both planer blades into the sharpening de-
vice and clamp them by tightening the wing bolt.
Make sure that both planer blades are complete-
ly inserted to the stop.
Move the sharpening device with the inserted
planer blades uniformly and with light pressure
across the whetstone.
Note: Never regrind the planer blades by more
than 6 mm, based on a minimum width of 23 mm.
Thereafter, both planer blades must be replaced.
Assembling the Planer Blade(s)
(see figures E–F)
Before reinserting new or resharpened planer
blades, clean the blade drum 13 and the planer
blades 15, if required, as well as the HSS planer-
blade retainer 16. Clean heavily gummed planer
blades with spirits or petroleum.
Note: Before assembling new or resharpened
planer blades, their correct height setting must
be adjusted first.
The setting gauge 19 (accessory) is used for ad-
justing the height of the planer blades. Place the
planer blade 15 and the blade retainer 16 on the
setting gauge. Make sure that the blade retainer
16 engages in the groove inteneded for this pur-
pose. Press the planer blade 15 against the stop
and lock the blade retainer 16 in this position
with the fastening screws 17. This will automati-
cally adjust the correct height.
Each planer blade must be assembled and
aligned centered to the planer base plate 8. Af-
terwards, tighten the three fastening screws 11
with the Torx key 10, ensuring the correct tight-
ening sequence ( ) on the clamping jaw 12.
Note: Before starting operation, check the fas-
tening screws 11 for tight seating. Rotate the
blade head 13 manually and ensure that the plan-
er 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 planer
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 re-
placed. Carbide blades (TC) may not be resharp-
ened.
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 clamp-
ing 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 en-
sures continuous height adjustment when re-
placing 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. Af-
terwards, tighten the three fastening screws 11
with the Torx key 10, ensuring the correct tight-
ening sequence ( ) on the clamping jaw 12.
Note: Before starting operation, check the fas-
tening screws 11 for tight seating. Rotate the
blade head 13 manually and ensure that the plan-
er blades do not graze.
