SAFETY RULES
W oodworking can be dangerous if safe and proper operating procedures are not followed. As with all machinery, there are cert ain
hazards involved with the operation of the product. Using the machine with respect and caution will considerably lessen the possi -
bility of personal injury . However, if normal safety precautions are overlooked or ignored, personal injury to the operator may result.
Safety equipment such as guards, push sticks, hold-downs, featherboards, goggles, dust masks and hearing protection can reduce
your potential for injury . But even the best guard won t make up for poor judgment, carelessness or inattention. Always use common
sense and exercise caution in the workshop. If a procedure feels dangerous, don t try it. Figure out an alternative procedure that feels
safer . REMEMBER: Your personal safety is your responsibility.
This machine was designed for cert ain applications only. Delt a Machinery strongly recommends that this machine not be modified
and/or used for any application other than that for which it was designed. If you have any questions relative to a p articular applica -
tion, DO N O T use the machine until you have first cont acted Delt a to determine if it can or should be performed on the product.

DEFINITIONS O F JOINTING A N D PLANING OPERATIONS
Fig. 2
Fig. 3
JOINTING OPERATIONS Jointing cut s or edge jointing is the simplest and most common operation which can be
done on the jointer and these cut s are made to square an edge of a workpiece. The fence is square with the t able and
the depth of cut is approximately 1/8 inch. The workpiece is positioned on the jointer with the narrow edge of the work -
piece on the infeed t able and the major flat surface of the workpiece against the fence, as shown in Fig. 2. The work-
piece is moved from the infeed t able, across the cutterhead to the out feed t able. CAUTION: Never pass your hands
directly over the cutterhead and use push blocks to feed the workpiece whenever possible .The hand over the
out feed t able presses the work down so that the newly-formed surface will make perfect cont act with the t able. The hand
over the infeed t able (usually the right hand) exert s no downward pressure, but simply advances the work to the
cutterhead. Both hands exert pressure to keep the work in cont act with the fence.
PLANING OPERATIONS Planing or surfacing is identical to the jointing operation except for the position of the work -
piece. For planing, the major flat surface of the workpiece is placed on the infeed t able of the jointer with the narrow
edge of the workpiece against the fence, as shown in Fig. 3. The workpiece is moved from the infeed t able, across the
cutterhead to the out feed t able est ablishing a flat surface on the workpiece. Always use push blocks when performing
planing operations and NEVER pass your hands directly over the cutterhead.

INFEED TABLE
ADJUSTMENTS
To raise or lower the infeed t able, loosen t able lock handle
(A) Fig. 28, and move the t able raising and lowering hand
lever (B) up or down until the t able is at the desired position
and tighten t able lock handle (A). NOTE: The t able lock
handle (A) can be repositioned by pulling out the handle
and repositioning it on the serrated nut located under the
handle.
The depth of cut of the infeed t able (position of t able in
relationship with the cutting circle) can be read with the
English/Metric scale and pointer (G) Fig. 28.
Positive stop s are provided on the jointer to limit the height
and depth of the infeed t able. T o adjust the stop s, simply
loosen two locknut s (C) and (D) Fig. 29, and turn the two
adjustment screws (E) and (F) as necessary.Retighten
locknut s (C) and (D). W e recommend that the height of the
infeed t able be adjusted so the t ableatit s highest point will
be 1/2mm below the highest point of the knives. This is an
import ant feature of your jointer which enables you to
rapidly position the infeed t able for a finish or a final cut.

OUTFEED TABLE
ADJUSTMENTS
For most jointing operations the out feed t able must be
exactly level with the knives at their highest point of revolu -
tion. To move the out feed t able, loosen lock handle (A)
Fig. 30, and move the t able raising and lowering hand lever
(B) up or down until the t able is level with the knives.
It may be necessary to adjust the positive stop s. Loosen
the two locknut s (D) and (E) Fig. 31, and the two adjusting
screws (F) and (G) when moving the t able up or down.
When the t able is exactly level with the knives at the
highest point of revolution, tighten lock handle (A) Fig. 30,
and turn adjusting screw (F) Fig. 31, until it bottoms; then
tighten locknut (D). Screw (G) is also a positive stop for the
lower limit of the out feed t able. W e suggest that this stop
also be tightened when the out feed t able is set level with
the knives. This will prevent the out feed t able from acci -
dently being lowered.
ADJUSTING BELT TENSION
The jointer is shipped with two V -belts assembled and
properly tensioned to the cutterhead and motor pulley.If
it becomes necessary to adjust belt tension, proceed as

mately 1/2 inch deflection at the center sp an of the belt s,
as explained in STEP 3.
ADJUSTING
SPRING TENSION OF
CUTTERHEAD GUARD
The cutterhead guard (A) Fig. 35, completely covers the
cutterhead. During operation the material being jointed or
planed pushes the guard (A) out of the way and at the
completion of the cut, the guard (A) springs back over the
cutterhead providing full coverage. If it ever becomes
necessary to adjust the spring tension of the cutterhead
guard (A), loosen two screws (B) and turn screw (C) clock -
wise to increase or counterclockwise to decrease the
spring tension. Then tighten the two screws (B).
OPERATION
The following directions will give the beginner a st art on jointer operations. Use scrap pieces of lumber to
check settings and to get the feel of the operations before attempting regular work.
W ARNING: A LW AY S U S E CUTTERHEAD GUARDANDKEEP HANDS AW AY FROMCUTTERHEAD.
ALW AYS USE PUSH BLOCKS WHENEVER POSSIBLE.
Fig. 36
PLACEMENT OF HANDS
DURING FEEDING
At the st art of the cut, the lef t hand holds the work firmly
against the infeed t able and fence, while the right hand
pushes the work toward the knives. Af ter the cut is under -
w a y, the new surface rest s firmly on the out feed t able as
shown in Fig. 36. The lef t hand should then be moved to
the work on the out feed t able, at the same time maint ain -
ing flat cont act with the fence. The right hand presses the
work forward, and before the right hand reaches the cutter-
head, it should be moved to the work on the out feed t able.

JOINTING AN EDGE
This is the most common operation for the jointer. Set the
guide fence square with the t able. Depth of cut should be
the minimum required to obt ain a straight edge. Hold the
best face of the piece firmly against the fence throughout
the feed as shown in Fig. 37.
D O N O T perform jointing operations on material shorter
than 14 inches, narrower than 3/4 inch or less than 1/2 inch
thick.
N E V E R pass your hands directly over the cutterhead and
use push blocks to feed the workpiece whenever possible.
PLANING OR SURFACING
Planing or surfacing is identical to the jointing operation
except for the position of the workpiece. For planing, the
major flat surface of the workpiece is placed on the infeed
table of the jointer with the narrow edge of the workpiece
against the fence, as shown in Fig. 38. The workpiece is
moved from the infeed t able, across the cutterhead to the
out feed t able est ablishing a flat surface on the workpiece.
Always use push blocks when performing planing opera -
tions and NEVER pass your hands directly over the cutter -
head.
D O N O T perform planing or surfacing operations on mater-
ial shorter than 14 inches, narrower than 3/4 inch, wider
than 12 inches or less than 1/2 inch thick.
BEVELING
To cut a bevel, lock the fence at the required angle and run
the work across the knives while keeping the work firmly
against the fence and t ables. Several p asses may be nec-
essary to arrive at the desired result. When the angle is
small, there islittle dif ference whether the fence is tilted to
the right or lef t. However, at greater angles approaching 45
degrees, it is increasingly dif ficult to hold the work properly
when the fence is tilted to the right. The advantage of the
double-tilting fence is appreciated under such conditions.
When tilted to the lef t, the fence forms a V -shape with the
tables, and the work is easily pressed into the pocket while
passing it across the knives as shown in Fig. 39. If the
bevel is laid out on the piece in such direction that this
involves cutting against the grain, it will be better to tilt the
fence to the right.

TAPER CUTS
One of the most useful jointer operations is cutting an edge to a t aper.The method can be used on a wide variety of work.
Tapered legs of furniture are a common example.
Instead of laying the piece on the infeed t able, lower the forward end of the work onto the out feed t able. Do this very care -
fully , as the piece will sp an the knives and they will t ake a bite from the work, with a tendency to kickback unless the piece
is firmly held. Now push the work forward as in ordinary jointing. The ef fect is to plane of f all the stock in front of the knives
to increasing depth, leaving a t apered surface.
The ridge lef t by the knives when st arting the t aper may be removed by taking a very light cut according to the regular method
for jointing, with the infeed t able raised to it s usual position.
Practice is required in this operation, and the beginner is advised to make trial cut s on waste material. Taper cut s over p art
of the length and a number of other special operations can easily be done by the experienced craf tsman.

CUTTING A RABBET
When making a rabbet cut, as shown in Fig. 40, the cutter -
head guard must be removed. AFTER THE RABBET CUT
IS COMPLETED, BE CERTAIN GUARDIS REPLACED.
CAUTION: Use pushblocks whenever possible, as shown.
1. Adjust the fence so that the dist ance between the end
of the knives and the fence is equal to the wid th of the
rabbet.
2. Lower the infeed t able an amount equal to the depth of
the rabbet. If the rabbet is quite deep, it may be necessary
to cut it in two or more p asses. In that event, the t able
is lowered an amount equal to about half the depth of the
rabbet for the first p ass, then lowered again to proper depth
to complete the cut.

JOINTING OR PLANING WARPED WOOD
If the wood to be jointed is dished or warped, t ake light cut s until the surface is flat. A void forcing such material down against
thet able; excessive pressure will spring it while p assing the knives, and it will spring back and remain curved af ter the cut is
completed.
DIRECTION O F GRAIN
A void feeding the wood into the jointer against the grain as shown in Fig. 41. The result will be chipped and splintered edges.
Feed with the grain as in Fig. 42, to obt ain a smooth surface.

MAINTENANCE
REMOVING, REPLACING A N D SETTING KNIVES
If the knives are removed from the cutterhead for replacement or regrinding, care must be used
in removing, replacing and resetting them as follows:
1. DISCONNECT THE MACHINE FROM THE POWERSOURCE.
2. Move the fence to the right until it is clear of the cutterhead.
3. Loosen two screws (A) Fig. 43, and remove cutter -
head guard assembly (B). W ARNING: B E EXTREMELY
CAREFUL THAT YOUR HANDS D O NOT COME IN
CONTACT WITH THE KNIVES.
4. Using wrench (C) Fig. 44, slightly loosen the six knife
locking screws (D) in each knife slot by turning the
screws (D) clockwise .This relieves stress in the cutter -
head.
5. Loosen screws (D) Fig. 44, further , and remove the
knife, knife locking bar and lif ter springs located under
the knives. Remove the remaining two knives in the same
manner.
6. Before replacing the knives, make cert ain the knife
locking bars are throughly clean and free of gum and
pitch and adjust the height of the out feed t able to be
.030 above the cutterhead body as follows:
A. Using a straight edge (E) Fig. 45, and feeler
gages (F) that equal .030 , adjust the height of
the out feed t able to be .030 above the cutter -
head body (G). Then lock the out feed t able in
place.

7. IMPORTANT:For ease in rot ating the cutterhead
during the knife setting operation, pull outward on latch
(H) Fig. 46, and open hinged access door (J). This pro -
vides access to the cutterhead pulley (K) Fig. 47, and
belt (L) allowing you to rot ate the cutterhead. CAUTION:
Af ter knives are adjusted, make cert ain the access door
(J) is in the closed and locked position.
8. Replace the knife locking bars, lif ter springs and
knives into each slot in the cutterhead. W ARNING: CARE
MUST BE TAKEN WHEN INSERTING TH E KNIVES
A S THE CUTTING EDGES ARE VERY SHARP. Push
the knives down as far as possible and snug up the knife
locking screws by turning them counterclockwise just
enough to hold the knives in position.
9. Construct a U shaped block out of hardwood simi -
lar to the one shown at (M) Fig. 48, and place this block
on the rear t able over the cutterhead, as shown. Using
wrench (C), loosen knife locking screws by turning them
clockwise. The knife (O) willlif t up and cont act the ends
of the gage block (M). The knives are adjusted correctly
when the cutting edge of the knife cont act s the gage
block when the knife is at it s highest point. When you are
cert ain the knife is adjusted properly, tighten the knife
locking screws by turning them counterclockwise.
10. Adjust the remaining two knives in the same manner.
W ARNING: MAKECERTAIN THAT ALL KNIVES A R E
SECURELY FASTENED IN CUTTERHEAD BEFORE
TURNING O N POWER.
11. Replace cutterhead guard.
