Replacing The Drive Belt; Maintenance And Cleaning - Bosch PHO 20-82 Bedienungsanleitung

Replacing the Planer Blade
Before any work on the machine itself, pull
the mains plug.
Be cautious when replacing the planer
blades: Possible danger of injury due to the
sharp cutting edges of the planer blades!
Do not grasp the planer blades by the cut-
ting edges.
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 must be replaced. The carbide blade (TC)
may not be resharpened.
Disassembling the Planer Blades
(see figure )
E
To reverse or replace the planer blade, rotate the
blade drum 22 until it is parallel to the planer base
plate 11.
Loosen the two fastening screws 25 with the
Allen key 24 by approx. 1 – 2 turns.
If necessary, loosen the clamping element 23
by giving it a light blow with a suitable tool
(e. g. a wooden wedge).
Push the planer blade 26 sidewards out of
the blade drum with a piece of wood.
Assembling the Planer Blades
(see figure )
F
The guide groove of the planer blade always en-
sures continuous height adjustment when replac-
ing or reversing it.
Clean the blade seat (clamping element) and the
planer blade respectively, if required.
When assembling the planer blade, ensure that it
is seated properly in the blade holder of the
clamping element 23 and aligned flush at the side
edge of the rear planer base plate 11.
Afterwards tighten the fastening screws 25
again.
Before restarting, check if the clamping
screws 25 are tightened well.
Rotate the blade drum 22 by hand and en-
sure that the planer blade does not run into
the planer base plate or housing.
