for this pur-
pose. If the
blade is
gummed and
difficult to re-
move, you
may clean the
blade with
mineral spir-
its, lacquer
thinner or al-
cohol. Clean all seating surfaces before rein-
stalling the new blades, as this will ensure an
accurate blade setting and proper tool perfor-
mance.
Blade Adjustment
Reassembly of the blades and blade holders is
essentially the reverse of the disassembly pro-
cedure, but the following points should be
noted. When reinstalling the blades and blade
holders, it is important that the blade holders
rest firmly against the side stop of the cutter
drum 23 (position 1), before it is secured into
place. To ensure an even cut, it is important that
the blades are adjusted so that they align with
the outside edge of the front and rear shoes.
This alignment can be done as follows: place a
straight edge or a piece of wood along the
outside surface of the front shoe 10 and rear
shoe 22, then slide the planer blade 24 to just
contact the straight edge or wood (position 2).
Note that this adjustment must be done by
sliding the blade in its blade holder, and that the
blade holder
10
must remain
in contact with
the cutter
drum side
stop. You
may then
tighten the
c l a m p i n g
screws 21
which secure
the blade holders evenly and alternately for
both blades, and your planer is ready for use.
Blade Leveling
The blade leveling screws 27 are factory set
with a fastening compound, and do not require
readjustment or removal under normal circum-

stances. If adjustment is required, it may be
done as follows. First set the front shoe 10 to
the zero "0" position. Next place a straight edge
over the front shoe 10 and rear shoe 22 and
check the height of both ends of the blades.
Both ends of the blades should just contact the
straight edge. If the blade edge is not perfectly
parallel with the shoes, you may raise or lower
the blade holder 26. With the clamping screws
21 loosened raise or lower the blade leveling
screws 27,
10 27
which will al-
low you to ad-
just the blade
holder 26 up or
down until the
blade is paral-
lel to the front
and rear shoes.
When this ad-
justment is
complete, the clamping screws 21 must be
tightened firmly. Be certain that there is no
foreign material between the blades 24, the
blade holders 26 or the cutter drum 23.
These adjustments are critical, and are best
performed by a Bosch Factory Service or Bosch
Authorized Service Center if required, as the
blade leveling screws 27 must again be fas-
tened with the proper chemical fastening com-
pound.
Special Cutting Applications
The planer comes with two carbide reversible
blades. Optional blade sets**, which are listed
on page 3 of this instruction manual, may be
purchased for different applications.
CAUTION! When changing to an optional
blade set you must first purchase and install the
correct blade conversion kit, as listed. The
conversion kits include a different set of blade
holders and one set of optional blades. Once
the conversion kit is installed you may order
replacement blade sets separately. Each time
you change from one style blade set to the next,
you must always change the blade holders also.
The various blade holders and blade sets are not
interchangeable with each other.
