To install the cutter knives:
Danger!
− Use only suitable cutter knives
conforming to EN 847-1 (see
"Available Accessories") – unsui-
table, incorrectly mounted, blunt
or damaged cutter knives can
work loose or increase the risk of
kickback considerably
tively.
− Always
replace both
knives.
− On the cutterblock and cutter
knife lockbar the numbers "1"
and "2" respectively are punched
in. When reassembling, ensure
that the numbers on cutterblock
and cutter knife lockbar match,
otherwise damage to the bearings
could occur by a balance error.
− Only cutter knives marked "HSS"
or "HS" can be resharpened!
When resharpening, remove the
same amount of material from
both cutter knives, otherwise a
balance error may cause damage
to the bearings.
− Cutter knives can only be reshar-
pened down to a minimum width
of 12 mm.
− Install cutter knives using only
genuine replacement parts.
8. Place spring clips back into their ori-
ginal position in the cutterblock's
groove.
9. Place the cutter knife lockbar in the
cutterblock's groove. Turn the three
square-head bolts so far out that the
cutter knife will just slide in.
10. Insert a sharp cutter knife and adjust
position with the cutter knife lockbar,
so that neither protrudes over the
edge of the cutterblock.

planer bed in the direction as indi-
cated by the arrows in the illustra-
tion:
