5.
The variation between one side and the other
should not be greater than 0.004". Repeat
steps 1-4
on the other two knives. Again, the
variation between all three knives should not
be greater than 0.004".
Once you have completed inspection on all three
knives, you will able to determine whether or not
there is a need to adjust the knives in the cutter-
head. Proceed to the appropriate section,
depending upon whether you are using the jack
screws or the springs.

Using the feeler gauge to
measure the gap.
The Model G0550/G0551 Planer has a three-
knife cutterhead. The cutterhead is located in the
head casting and rotates on two sealed bearings.
No lubrication is needed for the life of the bear-
ings.
Because of normal use and wear, the knives
must be periodically sharpened, replaced or
adjusted. Adjustment from the factory must also
be checked prior to use due to possible move-
ment during shipment.
To inspect the knives:
1.
Disconnect the machine from the power
source!
2
.
Lower the table and place the gauge block or
a Rotocator under one end of the cutterhead
.
3
.
Remove the V-Belt cover and carefully rotate
the belts to turn the cutterhead until the first
knife is at bottom dead center. Adjust the cut-
terhead height until the knife barely touches
the top of gauge block. Note—
Rock the cut-
terhead back and forth to determine bottom
dead center.
4
.
Slide the gauge block to the opposite side of
the cutterhead and check the same knife,
rocking back and forth to determine bottom
dead center.
— If the knife does not contact the gauge
block, use a feeler gauge to determine
the difference between one side and the
other. See
Figure 31
.
— If the knife bottoms out on the gauge
block, repeat
steps 1-3
, but start on the
opposite side of the cutterhead
.
When making adjustments, all three knives
must be adjusted the same. DO NOT adjust
one knife without adjusting the others as
well. Improper knife height adjustment can
result in damage to knives, poor planer per-
formance and possible operator injury.
Always adjust the thickness scale after
adjusting the knives.
