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".
Fig 42
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),

ADJUSTMENTS
Although your planer was carefully adjusted at the factory,
it should be checked before being put into operation. Any
inaccuracies due to rough handling in transit can easily be
corrected by following these directions.
In order to check the adjustments you will need a straight
edge, feeler gage and a homemade gage block made of hard¬
wood. This gage block can be made by following the dimen¬
sions shown in Fig. 45,
WHEN CHECKING ADJUSTMENTS, ALWAYS MAKE
SURE THE PLANER IS DISCONNECTED FROM THE
POWER SOURCE.
ADJUSTING BELT TENSION
To adjust the belt tension on your machine, proceed as follows:
1. Disconnect machine from the power source.
2. Remove belt and pulley cover from the machine.
3. . Place a 2 X 4 (A) Fig. 46, underneath the motor plate,
as shown,
4. Loosen two bolts (B) Fig, 46, and pry up on the motor
plate until correct belt tension is obtained. Correct tension
is obtained when there is approximately 1/4” deflection in
the center span of the belts using light finger pressure. Then
tighten two bolts (B) Fig. 46, and replace side cover.
Fig. 46
CHECKING, ADJUSTING AND
REPLACING KNIVES
When checking, adjusting or replacing the cutterhead knives,
proceed as follows:
1. Disconnect the machine from the power source.
2. Remove four screws, three of which are shown at (A)
Fig. 47, and remove top cover (B).
3. Loosen two screws (C) Fig. 48, and tilt motor assembly
(D) to the front as shown.
4. To check and adjust knives, proceed as follows:
A. Check all three knives for proper setting using
the knife gage as shown in Fig. 49. When the gage (A)
is placed on the cutterhead as shown, the knife should
just contact the bottom of both set screws [B) Fig. 49.
Fig. 47

B. If any of the knives require an adjustment,
slightly loosen the knife locking bar of each of the
three knives by turning the locking screws (D) Fig, 49,
into the locking bar just enough to relieve stress in the
cutterhead but not disturb the setting of the three
knives.
C. To adjust the knife that must be reset, loosen all
four locking screws (D) Fig. 49, by turning them into
the locking bar. As the knife locking bar becomes
loose, lifter springs under the knife will raise the knife
until it contacts the bottom of both set screws (B) of
the gage. Then snug up the knife locking bar by lightly
backing out the four locking screws (D) against the
knife slot. IMPORTANT: AT THIS TIME, ONLY
TIGHTEN THE KNIFE INTO THE SLOT ENOUGH
TO HOLD IT IN POSITION.
D. If additional knives must be reset, repeat Step C.
E. After all three knives are set with screws just
snug, back out and tighten the four locking screws (D)
Fig. 49, against the slot, starting with the end screws
first, then the center screws until the knife is securely
held in the cutterhead. Tighten the remaining two
knives in the same manner.
5. If the knives are removed for sharpening, care must be
exercised in replacing and resetting them, as follows:
A. To remove each knife, loosen the knife locking
bar, by turning the four locking screws (D) Fig. 49,
into the knife locking bar and remove the locking bar,
knife and springs located under the knife.
B. Remove the remaining two knives in the same
manner,
C. Thoroughly clean the knife slots, knife bars,
springs and screws. Check the screws. If the threads
appear worn or stripped or if the heads are becoming
rounded replace them.
D. Inspect the cutting edge of the knives for nicks
or wire edge. Hone the knives slightly using a stone or
if the knives are to be sharpened, maintain a cutting
angle of 35 degrees.
E. Insert springs, knives and knife locking bars into
all three slots in the cutterhead. Back out locking
screws (D) Fig. 49, just enough to hold all three knives
in the cutterhead.
F. Adjust all three knives as explained in Step 4,
above.
Fig. 49

ADJUSTING FEED ROLL SPRING
TENSION
The infeed roll (A) and outfeed roll (B) Fig. 50, are those
parts of yoLJr planer that feed the stock while it is being planed.
The feed rolls (A) and (B) are under spring tension and this
tension must be sufficient to feed the stock uniformly through
the planer without slipping but should not be too tight that it
causes damage to the board. The tension should be equal at
both ends of each roll.
To adjust the spring tension of the infeed roll, turn screw {C)
Fig. 51, and also the screw on the opposite end of the roll.
To adjust spring tension of the outfeed roll, turn screw (D)
Fig. 51, and also the screw on the opposite end of the planer.
ADJUSTING HEIGHT OF OUTFEED
ROLL
The outfeed roll is adjusted at the factory to be set .040"
below the cutting circle. To check and adjust the outfeed roll,
proceed as follows:
1. Disconnect machine from the power source.
2. Make sure the knives are adjusted properly as explained
underCHECKING.ADJUSTING AND REPLACING KNIVES.
3. Place the gage block (A) Fig. 52, on' the table directly
underneath the cutterhead, as shown. Using a .040" feeler
gage (B) Fig. 52, placed on top of the gage block, raise or
lower the head until the knife (C) just touches the feeler gage
when the knife is at its lowest point. Do not move the head
any further until the outfeed roll is adjusted.
Fig. 52
4, Move the gage block (AJ Fig, 53, under one end of the
outfeed roil (B) as shown. The bottom of the outfeed roll
(B) should just touch the top of the gage block (A). If an
adjustment to the outfeed roll is necessary, loosen locknut
(E) and turn screw (F) until the feed roll just touches the gage
block. Then tighten locknut (E) Fig, 53.
5. Check and adjust opposite end of outfeed roll in the
same manner.
Fig. 53

ADJUSTING CHIPBREAKER
The chipbreaker is located on top of the planer and extends
down around the front of the cutterhead. The chipbreaker
raises as stock is fed through and "breaks or curls" the chips
the same as a plane iron cap on a hand plane. The bottom of
the chipbreaker must be parallel to the knives and set .040"
below the cutting circle. To check and adjust the chipbreaker,
proceed as follows:
1. Disconnect machine from the power source,
2. Make certain the knives are adjusted properly as pre¬
viously explained under CHECKING, ADJUSTING AND
REPLACING KNIVES.
3. Place the gage block (A) Fig. 54, on the table directly
underneath the cutterhead, as shown. Using a .040" feeler
gage (6) Fig. 54, placed on top of the gage block, raise or
lower the head until the knife (C) just touches the feeler gage
when the knife is at its lowest point, Do not move the head
any further until the chipbreaker Is checked and adjusted if
necessary.
4. Move the gage block (A) underneath the chipbreaker
(D) as shown in Fig. 55, The bottom of the chipbreaker should
just touch the top of the gage block. Check opposite end of
chipbreaker in the same manner.
5. If an adjustment to the chipbreaker is necessary, loosen
nuts (F) Fig. 56, and turn screws (E) until bottom of chip-
breaker just touches gage block. Then tighten nuts (F).
ADJUSTING TABLE ROLLS
Your planer is supplied with two table rolls (A) Fig, 57, which
aid in feeding the stock by reducing friction and turn as the
stock Is fed through tiie planer. It is not possible to give exact
dimensions on the proper height setting of the table rolls
because each type of wood behaves differently. As a general
rule, however, when planing rough stock the table rolls should
be set HIGH and when planing smooth stock the table rolls
should be set LOW.
The table rolls on your planer are set for average planing and
are parallel to the table surface. If you desire to adjust the
table rolls higher or lower, proceed as follows:
1. Disconnect machine from the power source.
2. Lay a straight edge (B) Fig. 58, across both rolls and
^ with a feeler gage (C) as shown, adjust height of table rolls
by loosening set screws (D) Fig, 57, and turn screws (E) to
raise or lower table rolls fA). Table rolls must also be adjusted
on the opposite end of table in the same manner. The table
rolls must always be set parallel to the table.

Fig. 58

ADJUSTING CUTTINGHEAD PARALLEL
TO TABLE
The cuttinghead is set parallel to the table at the factory and
no further adjustment should be necessary. If your machine is
planing a taper first check to see if the knives are set properly
in the cutterhead. Then check to see if the table is set parallel
to the cuttinghead as follows:
1. Disconnect machine from the power source.
2. Place gage block (A) Fig. 59, on table directly under
front edge of head casting (B) as shown. Lower head casting
until front edge of head casting {B) just touches gage block.
3. Move gage block <A) Fig. 60, to opposite end of table,
as shown. Distance from table to edge of head casting should
be the same.
4. Repeat STEPS 2 and 3 on outfeed end of table.
Fis- 59
Fig. 60
5. I f head casting Is not parallel to table, tilt planer on its
side as shown in Fig. 61. Remove bolt (C) and loosen bolt (D)
Fig. 61, wliich will allow you to move the idler sprocket
assembly (E) far enough to release tension on chain as shown
in Fig. 62. Remove chain from sprocket on end of headcast¬
ing that must be adjusted. In this case chain has been removed
from sprocket (F).
6. Turn sprocket (F) Fig. 62, by hand to bring that corner
into adjustment with other three corners. IMPORTANT;
THIS ADJUSTMENT IS VERY SENSITIVE AND IT
SHOULD NOT BE NECESSARY TO TURN THE SPROCKET
MORE THAN ONE OR TWO TEETH. Turning sprocket (F)
clockwise will decrease the distance between the table and
headcasting. Counter-clockwise will increase the distance.
7. Replace chain being careful not to disturb the position
of the sprockets and replace idler sprocket assembly (E) Fig.
61.
