I. INSTALLATION
A. SELECTING FLOOR SPACE
The planer should be placed with adequate room
both in front and back for dressing long stock. It should
set on a level foundation and can be bolted permanently
in place if preferred.
If a central dust collecting system is accessible,
it can be connected to the planer by installing 1t22-115
shaving hood. This hood and other accessories are
available from your Delta dealer.
IMPORTANT
We urge you to read these instructions carefully
and save them for future reference. When ordering re-
placement parts from your Delta dealer, always furnish
part number, description, model number and serial num-
ber of your machine.
B. REMOVING
PROTECTIVE COATING
Remove
protective coating from machined surfaces
using kerosene or similar solvent. Do not use lacquer
thinner or acetone.
C. INSTALLING MOTOR FIG. 2.
1. Place motor pulley on shaft, approximately 1/16"
from end of motor and tighten set screw. Remove
rear panel from planer base and bolt motor to
motor plate.
~
2. Remove plate on right hand side of planer and
align motor pulley and cutterhead pulley. Use a
narrow
straight edge or string, and slide motor to
the right or left so that both pulleys are in line.
3. Tighten set collars on tie rod and install "V"
belt. Motor can be adjusted up or down by turning
nuts on "I" bolts to appJ..y correct belt tension.
Belt should only be tight enough so that it can be
"flexed" approximately 1", applying finger pres-
sure midway between the pulleys. Tighten both
nuts against motor plate.
Tighten screw and locknut (15 ) ( 45 )under-
neath rear tie rod. See FIG. 22 of parts list.
D. ELECTRICAL CONNECTIONS

II. ADJUSTMENTS
A. LEVELING TABLE FIG. 4
The table should be parallel to the cutter head. To
check this, feed two pieces of stock simultaneously
through the planer at the extreme right and left hand
sides. Check the thickness of both pieces and if not
alike the table can be adjusted.
1. Raise low side of table by first loosening screw
in adjusting nut.
2.
Insert l4" rod in hole in nut, turn nut required
amount, and tighten screw.
3. Make another trial cut on the two pieces of stock,
check thickness and repeat step 2, if necessary.
Figure 4
B. TABLE GIBS FIG. 5
As the table raises and lowers, it bears against
machined surfaces, and over aperiod of time these
2
surfaces will wear. To compensate for this wear, the
gibs must be adjusted.
1. If table raised too freely or if fits loosely against
column, the gibs must be taken up.
2.
Loosen locknuts and slightly tighten each screw.
If table can be moved without undue effort, and
there
is no perceptible play between the table and
column, tighten locknuts.
3. If extra effort is required to move table, the gibs
may be too tight. Loosen locknuts and screws.
Figure 5
C. TABLE ROLLS FIG. 6
Table rolls are set .005" above surface of table.
No adjustment should be necessary, however if the stock
drags and does not feed uniformly, adjustment can be
made.
Use a dial indicator, or a straight edge and feeler
guage to determine if the rolls are parallel to the sur-
face of the table, and adjust if necessary.
1. Place table roll gauge across roll, loosen jam
nut and turn bolt beneath end of roll adjusting it
up or down the required amount.
2.
The table roll gauge has three steps marked
"rough", "average", and "cabinet". When dress-
ing rough stock, the rolls are set high to reduce
the amount
of drag on the tables. Average and
cabinet are finer settings usually for redressing
stock.
D. FEED ROLLS FIG. 7
The feed rolls under spring tension. This tension
must be sufficient to feed the stock uniformly without
slipping and must be equal at both ends of each roll. To
adjust:

1. Loosen locknuts and turn screws the required
amount.
NOTE: The tie bar in front of the infeed roll is
permanently set 1/8" above the bottom of the cut-
ting circle. This prevents making a cut beyond
the maximum
which is 1/8". If the stock being
planned is tapered beyond this amount, it will
stall when it becomes wedged under the tie bar.
THE FEED ROLLS DO NOT REQUIRE ADJUST-
MENT. The stock should be reversed and fed
through' the
planer, thick end first.
Figure 7
E. CHIPBREAKER FIG. 7
The chipbreaker is the large casting containing the
namephte on top of the planer. It pivots on the front tie
har and n.ises as stock is fed through. It causes the
chips to ~e thrown out to the rear and requires no ad-
ju.>tmef't To remove when necessary:
1. Remove four screws lift up on left side, sliding it
in that direction away from stop Din in right hand
column.
Figure 8
F. PRESSURE BAR FIG. 8
The pressure bar is located directly behind the cut-
terhead and rides on the planed surface of the stock
pressing it down on the table. The pressure is exerted
by rubber pressure pads which can be adjusted if nec-
essary.
1. Remove hexagon nuts, washers and pressure pads.
2.
Turn adjusting nuts moving the pressure bar up at
down so that it just touches the surface of the
stock. Turning the nut clockwise, will raise it,
counterclockwise will lower it.
3. Replace pressure pads, washers and hexagon nuts.
Hold adjusting nut with a wrench and turn hexagon
nut compressing rubber pressure pad. Turn each
nut
the same amount.

I. DEPTH SCALE FIG. 12
The depth scale indicates the distance between the
table and the bottom of the cutting circle. It should be-
adjusted if the knives are sharpened in the head or if
the knives are replaced.
1. Dress a piece of stock and measure the thickness.
2. If pointer on table does not indicate this thick-
ness dimension on scale. loosen screws and move
scale up or down the required amount.

J. SHIFTER OR CLUTCH FIG. 13
When the clutch is engaged, it is held in this posi-
tion by means of two spring loaded pins between the two
collars on the shifter rod.
Should
the clutch disengage frequently during nor-
mal
operation, it may require adjustment.
1. Remove set screw holding small collar in shifter
rod. Move the collar to expose the pins and note
the three small holes in this collar. Also notice
the hole in the shaft for the dog point set screw
just removed. When the clutch is engaged, both
pins engage in two of holes. When it is dise ngag-
ed, only one pin engages with one hole.

2. Slide the collar back to its original position with
both pins engaged in two of the holes and replace
the set screw engaging the dog point with the hole
in the shaft. This fixes its position on the shaft.
3. Loose nthe set screw holding the large collar in
the casting and move shifter handle to the right,
engaging clutch. This will rotate the large collar
to the correct position. Tighten set screw.

A. CLEANING
GROOVE
Machined surfaces of castings, cutterhead and roll-
ers should be cleaned with Delta Gum and Pitch Re-
mover No. 4051. Never use asharp instrument to remove
pitch accumulation.
The edge of the pressure bar which bears on the
stock should also be kept free of pitch accumulation and
chips so as not to score the finished surface of the
stock.
With an air hose, blowout any loose chips which
gather in the corners.
Figure 21 7
Figure 22
Irregular Cuts
There are times when the cutter head will make
irregular or uneven cuts, which are made because
certain adjustments of the machine are out of line.
The most common of these and what to do to
c<nect them are listed as follows:

When a ridge appears on the work as shown in
(1) Figure 22, it indicates that the infeed table roller
is too high. To correct this it will be necessary to
lower the infe'ed idle roller in the table. These rollers
are set· at the factory at .005" above the level of the
table, which is the maximum, if the rollers are more
than 005" the above condition will result, refer to
Figure 6.
When a slight groove is cut in the planed surface
as shown in (2) Figure 22, it is known as a pressure
bounce and indicates too great a pressure on the infeed
roll. To correct this, relieve the pressure on the infeed
roll by turning out pressure screw SP-172, see Fig-
ure 7.
When a piece of work is planed and the end cut
appears as in (3) Figure 22, it is known as a sniped
end. This indicates that the table is too loose and is
corrected by tightening the gibs on the table, refer to
Figure 5.
8
When the work shows feed roller marks as shown
in (4) Figure 22, the infeed roller pressure is too great.
Reduce the pressure on roller by turning out adjust-
ment screws on top of right and left hand columns,
see Figure '7.
When the stock is put through the machine wrong,
that is against the grain, a chipped edge will result,
as shown in (5) Figure 22. Turn the wood around, end
for end, so that the cutter will cut with the grain and
you will get anice, smooth, even cut.
When the material has a taper cut, that is from side
to side it indicates that the table is not parallel to the
cutter head, as shown in (6) Figure 22. In this case
all that is necessary is to adjust the table so that it is
parallel to the cutter head, refer to Figure 4-
Keep the table top clean and free of chips at all
times, so that no chips can get under the material
and cause gouges or scratches on under side of material.
