Setting up the planing knives fig. 16a, b, c
• The HSS planing knives are inserted in the
factory and set up correctly.
Problem
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.
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 planing knives are positioned on the
head of the setting screws in the slot of the
cutterblock. Let the knives touch the boards
by unscrewing the setting screws with an Al-
len key.
• Align the knife support and check the posi-
tion of the knives again.
• 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 re-
placement and tighten the pressure screws
afterwards (8.9 N/m).
Before using the cutterblock, check if the in-
structions above were followed.
Before turning on the machine, the general
safety notices must be observed.

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 paral-
lel after incorrect transport or similar. Never lift the
machine by the tables.
Sharpening of planing knives
Blunt planing knives increase the risk of acci-
dents and the performance is no longer guar-
anteed.
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.
