DEPTH OF CUT ADJUSTMENT
The depth of cut on your planer is controlled by raising or
lowering the head assembly (A) Fig. 40, which contains the
cutterhead and feed rolls. The head assembly (A) raises and
lowers on four precision ground steel columns. To adjust for
depth of cut simply loosen the two head assembly lock knobs
(C) and turn the elevating handle (D) Fig, 40. After the
desired depth of cut is obtained, lock the two head assembly
lock knobs (C) Fig. 40. A combination inch/metric scale
(B) Fig. 40, is conveniently located on the right front column
for easy reading.
The maximum depth of cut on full width planing with the 3
horsepower. Three Phase motor is 3/16" {4.763 m m).
The maximum depth of cut on full width planing with a
2 Horsepower, Single Phase motor is 1/8" (3.175 m m). A
limiter (A) Fig. 41, is provided on single phase machines
to limit the depth of cut on full width planing from 3/16"
to 1/8".

ANTI-KICKBACK FINGERS
Anti-kickback fingers (A) Fig. 42. are provided on your planer
to prevent kickback. These fingers operate by gravity and it
is necessary to inspect them occasionally to make sure they
are free of gum and pitch so that they move independently
and operate correctly.
FEED ROLL SPEED CONTROL
Your machine is equipped with a spiral, serrated infeed roll
(B) and a solid steel outfeed roll (C| Fig. 42.
When the feed rolls are engaged, they turn and feed the stock.
The feed rolls slow automatically when the machine is under
^ heavy load for best planing under all conditions. The feed
rolls are driven by a chain and sproket drive (D) Fig. 43, which
takes power directly from the cutterhead through the oil
bath gear box (E).
To engage the feed rolls, pull out lever (F) Fig. 44. To dis¬
engage the feed rolls push in on lever (F),
