ADJUSTING CUTTERHEAD PARALLEL TO TABLE
The cutterhead casting and blades have been set paral-
lel in the factor y. If your planer is not cutting parallel,
this may be caused by the blades not being properly
set.
If you can find no other reason for the out of parallel,
check cutterhead casting is parallel by the following pro-
cedure using your wooden gauge block.
1. After machine is disconnected from power source,
put gauge block on the table under the casting.
Lower head so it just touches the gauge block
Fig. 17.
2. Move block to the opposite end to check if it is the
same distance from the casting to the block.
Fig. 18.
3. Repeat process at rear of machine.
4. If the head casting is not parallel to the table, tilt
machine on its’ side and loosen the bolt Fig. 19 (A)
and loosen bolt Fig. 19 (B). You will need to adjust
the idler sprocket assembly Fig. 19 (C) to release
the tension on the chain.
5. Remove chain from sprocket on corner of
headcasting that needs adjustment.
6. Turn sprocket gently by hand to bring that corner
into line with the others. One or two teeth should be
enough. Clockwise will decrease the table distance
from the headcasting anticlockwise will increase it.
7. Replace chain without disturbing the new setting.
Put idler sprocket assembly back into place and
tighten bolts.
