Setting up the planing knives fig. 16a, b, c
• The HSS planing knives are inserted in the
factory and set up correctly.
If required, you can re-do the settings or refine
them as described.
• Adjust one planing knife after the other.
• Set the position of the planing knife using the
setting screws alternatively until the blade
of the knife touches both perfectly trimmed
boards (used as adjustment gauge) which
are placed on the unloading table.
• Set the loading table to a dressing height of
2 mm.
• Rotate the cutterblock until the knife has
reached the maximum height.
• The knife support is positioned on the head
of the setting screws in the slot of the cut-
terblock. Let the knives touch the boards by
unscrewing the setting screws with an Allen
key.
• Align the knife support and check the position
of the knives again.

1. Irregular and interrupted
transport during
thicknessing
2. Work piece ledge during
jointer work
3. Work piece irregularity
during jointer work (hollow,
crowned)
Electrical maintenance work may be carried out only by a qualified electrician!
When disposing of the machine, local legal stipulations must be complied with.
• Checking the knives
Put a trimmed board (adjustment gauge) on
the unloading table and mark the position of
the board.
By turning the cutterblock in the cutting direc-
tion by hand, the knife blade should move the
board by x = 2 to 3 mm. Carry out this check
for every knife on the operating side and on
the other side.
Without careful settings, the trimming cannot
be exact.
• Tighten the pressure screws on the v-ledge
with a flat spanner (8.9 N/m).
• Adjust all planing knives in the same way
and clamp them.
• Carry out a test-run after every knife repla-
cement and tighten the pressure screws
afterwards (8.9 N/m).
Before using the cutterblock, check if the inst-
ructions above were followed.
Before turning on the machine, the general
safety notices must be observed.
Sharpening of planing knives

accidents and the performance is no longer
Trouble-shooting
Possible cause
Thicknessing table resinified or not oiled.
This is caused by badly adjusted planing knives.
Caused by jointer tables not standing exactly parallel
after incorrect transport or similar. Never lift the machi-
ne by the tables.
guaranteed.
Re-sharpen the planing knives only up to a
knife height of 16 mm. The cutting angle of the
knife should be 40 ± 2 degrees.
For re-sharpening, take the planing knives to
an authorised sharpening company or send
them back to the manufacturer.
