Note:

Before replacing or resharpening the plan-

er blades, remove the HSS planer-blade retainer

by loosening the fastening screws

Resharpening HSS Planer Blades (see figure D)

Worn or dull

HSS

planer blades can be resharp-

ened with the sharpening device

(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

and the planer

blades

, if required, as well as the HSS planer-

blade retainer

. 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

(accessory) is used for ad-

justing the height of the planer blades. Place the
planer blade

and the blade retainer

on the

setting gauge. Make sure that the blade retainer

engages in the groove inteneded for this pur-

pose. Press the planer blade

against the stop

and lock the blade retainer

in this position

with the fastening screws

. This will automati-

cally adjust the correct height.
Each planer blade must be assembled and
aligned

centered to the planer base plate

. Af-

terwards, tighten the three fastening screws

with the Torx key

, ensuring the correct tight-

ening sequence (

cde

) on the clamping jaw

Note:

Before starting operation, check the fas-

tening screws

for tight seating. Rotate the

blade head

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

must be re-

placed. Carbide blades (TC) may not be resharp-
ened.
