During transit or after long periods of use, the planer
knives may have shifted out of alignment. It is important to
check that the knives are properly aligned, adjusted and
set before using the machine.
Once the tables are aligned (see pages 12-15), the knives
can now be accurately set. This is a two stage procedure.
First the knives need to be set into the cutterhead block,
then they need fine adjusting to the table.
SETTING THE PLANER KNIVES - method 1
This method utilizes the knife setting gauge supplied.
1. Place the Knife Setting Gauge onto the cutterhead.
The knife must project so that it touches the notch interior
of the gauge. FIG. 33. Check both ends of the knife in the
cutterhead with the gauge, to make sure that the knife is
set at the same height. To adjust the knives;
2. Loosen the Lockbar (#87) in the block with the 10mm
square head Lockbar ‘Grub’ Set Screws (#86). FIG. 34.
3. Raise or lower the blade, as needed, with the Jacking
Screws (#85) that are accessed from the top of the
Lockbar. FIG. 35. Adjust the blade until it is accurately
set for height at both sides of the block, and also in the
middle
.
4. Tighten the Lockbar Grub Screws to secure the set
knives in the cutterhead.
NOTE:
To prevent distortion
of the lock bar and knife, start with tightening the grub
screws in the center, then move out to the outside screws.
THE MACHINE MUST NOT BE
PLUGGED IN AND THE POWER SWITCH MUST BE IN
THE OFF POSITION UNTIL ALL ADJUSTMENTS ARE
COMPLETE.
Wear gloves when changing the knives
to avoid the risk of personal injury by cuts that may result
from touching the sharp edges!

SETTING THE PLANER KNIVES - method 2
This method involves using a ruler, and a piece of wood or
aluminium straight edge, preferably one with a wide body.
1. Place the straight edge at either side of the cutterhead,
resting on both feed tables.
FIG. 36.
2. Slowly turn the cutterhead by hand, in the direction of
the cutting knives. If the planer knives are set correctly,
the end of the straight edge is moved forward 1/8” to
3/16”. FIG. 37. If the straight edge moves less than 1/8”,
the knives are set too low. If it moves further than 3/16”,
they are set too high.
3. See Method 1, steps 2-4, for information on how to
loosen the retaining screws to make knife adjustments.
4. This procedure must be performed at both ends of
the knife in the cutterhead. The straight edge movement
measurements must be exactly the same at both ends.
5. Then, the same measurement must be set to the other
two knives in the cutterhead to ensure that all 3 knives are
set at the same height.
