ADJUSTING HEIGHT
OF CHIPBREAKER
The chipbreaker extends down around the front of the
cutterhead and raises as stock is fed through the planer.
The chipbreaker “breaks or curls” the chips as they
leave the cutterhead and the bottom edge of the
chipbreaker helps hold the stock flat down on the table
during the planing operation. The bottom of the
chipbreaker must be parallel to the knives and set
0.020" below the cutting circle. To check and adjust,
proceed as follows:
DISCONNECT MACHINE FROM POWER
SOURCE
.
1.
Make certain the knives are adjusted properly as
explained under
“CHECKING, ADJUSTING AND
REPLACING KNIVES.”
2.
Place the gage block (A) Fig. 39, on the table directly
under the cutterhead as shown. Using a 0.020"
feeler gage (B) placed on top of the gage block,
raise or lower the head assembly until one of the
knives just touches the feeler gage when the knife is
at its lowest point. Then lock the head assembly in
this position.
3.
Place the gage block (A) Fig. 40, minus the feeler
gage, under one end of the chipbreaker (C), as
shown. The bottom of the chipbreaker (C) should
just touch the top of the gage block, as shown.
4.
If the height of the chipbreaker must be adjusted,
remove the top cover of the machine. Loosen nut (D)
Fig. 41, and turn screw (E) until that end of the
chipbreaker is properly adjusted. Then tighten nut
(D).
5.
Place the gage block on the other end of the
chipbreaker and if an adjustment is necessary
loosen nut (F) Fig. 41, and turn adjusting screw (G).
