SAFETY RULES
Woodworking can be dangerous if safe and proper operating procedures are not followed. As with all machinery, there are certain
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 com-
mon 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 certain applications only. Delta 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 particular applica-
tion, DO NOT use the machine until you have first contacted Delta to determine if it can or should be performed on the product.

WARNING: FAILURE TO FOLLOW THESE RULES
MAY RESULT IN SERIOUS PERSONAL INJURY
1. FOR YOUR OWN SAFETY, READ INSTRUCTION
MANUAL BEFORE OPERATING THE TOOL. Learn the
tool’s application and limitations as well as the specific
hazards peculiar to it.
2. KEEP GUARDS IN PLACE and in working order.
3. ALWAYS WEAR EYE PROTECTION.
4. GROUND ALL TOOLS. If tool is equipped with three-
prong plug, it should be plugged into a three-hole electrical
receptacle. If an adapter is used to accommodate a two-
prong receptacle, the adapter lug must be attached to a
known ground. Never remove the third prong.
5. REMOVE ADJUSTING KEYS AND WRENCHES. Form
habit of checking to see that keys and adjusting wrenches
are removed from tool before turning it “on.”
6. KEEP WORK AREA CLEAN. Cluttered areas and
benches invite accidents.
7. DON’T USE IN DANGEROUS ENVIRONMENT. Don’t
use power tools in damp or wet locations, or expose them
to rain. Keep work area well-lighted.
8. KEEP CHILDREN AND VISITORS AWAY. All children
and visitors should be kept a safe distance from work area.
9. MAKE WORKSHOP CHILDPROOF – with padlocks,
master switches, or by removing starter keys.
10. DON’T FORCE TOOL. It will do the job better and be
safer at the rate for which it was designed.
11. USE RIGHT TOOL. Don’t force tool or attachment to
do a job for which it was not designed.
12. WEAR PROPER APPAREL. No loose clothing, gloves,
neckties, rings, bracelets, or other jewelry to get caught in
moving parts. Nonslip footwear is recommended. Wear
protective hair covering to contain long hair.
13. ALWAYS USE SAFETY GLASSES. Wear safety glasses.
Everyday eyeglasses only have impact resistant lenses;
they are not safety glasses. Also use face or dust mask if
cutting operation is dusty.
14. SECURE WORK. Use clamps or a vise to hold work
when practical. It’s safer than using your hand and frees
both hands to operate tool.
15. DON’T OVERREACH. Keep proper footing and bal-
ance at all times.
16. MAINTAIN TOOLS IN TOP CONDITION. Keep tools
sharp and clean for best and safest performance. Follow
instructions for lubricating and changing accessories.

changing accessories such as blades, bits, cutters, etc.
18. USE RECOMMENDED ACCESSORIES. The use of
accessories and attachments not recommended by Delta
may cause hazards or risk of injury to persons.
19. REDUCE THE RISK OF UNINTENTIONAL START-
ING. Make sure switch is in “OFF” position before plugging
in power cord.
20. NEVER STAND ON TOOL. Serious injury could occur
if the tool is tipped or if the cutting tool is accidentally
contacted.
21. CHECK DAMAGED PARTS. Before further use of the
tool, a guard or other part that is damaged should be care-
fully checked to ensure that it will operate properly and
perform its intended function – check for alignment of mov-
ing parts, binding of moving parts, breakage of parts,
mounting, and any other conditions that may affect its
operation. A guard or other part that is damaged should be
properly repaired or replaced.
22. DIRECTION OF FEED. Feed work into a blade or cutter
against the direction of rotation of the blade or cutter only.
23.
NEVER LEAVE TOOL RUNNING UNATTENDED. TURN
POWER OFF
. Don’t leave tool until it comes to a complete
stop.
24. DRUGS, ALCOHOL, MEDICATION. Do not operate
tool while under the influence of drugs, alcohol or any
medication.
25. MAKE SURE TOOL IS DISCONNECTED FROM
POWER SUPPLY
while motor is being mounted, connected
or re-
connected.

FEED ROLL SPEEDS
Your planer is equipped with feed roll speeds of 20 feet
per minute and 30 feet per minute depending on belt
placement on the pulleys. As a rule, a faster feed rate is
used for general planing operations, while a slower feed
rate (because it provides more cuts per inch of stock)
gives a finer and smoother finish to the workpiece.
1. To engage the feed rolls, simultaneously push but-
ton (A) Fig. 16, and pull downward on handle (B).

CHECKING AND ADJUSTING TABLE ROLL HEIGHT
It is not possible to give exact dimensions on the proper height setting of the table rolls because each
type of wood has different behavioral patterns. As a general rule, when planing rough stock, the table
rolls should be set high (.003 to .005 ) above the table surface. When planing finish stock, the table
rolls should be set low (.001 ) above or level with the table surface.
To check and adjust the height of the table rolls, proceed as follows:
Fig. 22
1. DISCONNECT THE MACHINE FROM THE POWER
SOURCE.
2. With the table rolls in the lowest position, lay a
straight edge (A) Fig. 22, across both table rolls (B) on
the left side of the table as shown.

ANTI-KICKBACK FINGERS
A series of anti-kickback fingers (A) Fig. 27, are provided
on the infeed end of the planer to prevent kickback of the
workpiece during planing operations. These anti-kickback
fingers operate by gravity and no adjustment is required. It
is necessary, however, to inspect them occasionally to
make sure they are free of gum and pitch and that they
operate independently and freely.
WARNING: WHEN INSPECTING AND CLEANING THE
ANTI-KICKBACK FINGERS, MAKE CERTAIN THE
MACHINE IS DISCONNECTED FROM THE POWER
SOURCE.

slightly loosen the 12 locking screws, 10 of which are
shown at (F) Fig 34 and also in Fig. 35, just enough to relieve
stress in cutterhead (B) and not disturb the knife setting.
5. With knife setting gage (C) Figs. 34 and 35 still in place
on the cutterhead, continue to adjust the knife that must
be reset by turning the 12 knife locking screws CLOCK-
WISE until knife locking bar (G) becomes loose. Lifter
springs (not shown) located under the knife will automati-
cally raise the knife until it comes in contact with the gage
(C). Then snug up the knife locking bar (G) Fig. 34 and Fig.
35, by turning the ten screws (F) COUNTERCLOCK-
WISE. IMPORTANT: AT THIS TIME, ONLY TIGHTEN
THE KNIFE LOCKING BAR (G) JUST ENOUGH TO
HOLD THE KNIFE (D) IN POSITION INSIDE THE CUT-
TERHEAD SLOT.
6. If other knives need adjustment, repeat STEP 5.
7. After all the knives are positioned in the cutterhead
with the knife locking screws snug, turn each of the 12
locking screws (F) Fig. 34, COUNTERCLOCKWISE
UNTIL THE KNIVES ARE SECURE IN THE CUTTER-
HEAD. NOTE: When tightening the knife locking screws
(F), tighten the end screws first, then proceed inward
toward the center of the cutterhead.
IMPORTANT: If the knives are to be removed for sharp-
ening or replacement, extreme care should be taken
as the knives are very sharp. To remove the knives,
proceed as follows:
8. DISCONNECT THE MACHINE FROM THE POWER
SOURCE.
9. Carefully place knife setting gage (C) Fig. 34, so it is
positioned on the radiused section of the cutterhead (B)
Fig. 35.
10. Loosen knife locking bar (G) Figs. 34 and 35, by turn-
ing 12 knife locking screws, 10 of which are shown at (F)
CLOCKWISE and carefully remove locking bar (G), knife
(D), and springs (not shown) which are located under the
knife, from the cutterhead. Remove the remaining knives in
the same manner.
11. Thoroughly clean the knife slots, knife locking bars,
and locking screws. Check the screws; if the threads
appear worn or stripped, or if the heads are damaged,
replace them.

CONSTRUCTING
GAGE BLOCK
In order to check and adjust the height of the chipbreaker,
pressure bar, infeed and outfeed rolls and adjust the cut-
ter-head parallel to the table, you will need a gage block
made of hard wood. The gage block can easily be con-
structed by following the dimensions shown in Fig. 36.
ADJUSTING CHIPBREAKERS
The chipbreakers (A) Fig. 37, are located on top of the
planer and extend downward around the front of the cut-
terhead. The chipbreakers will raise as stock is fed through
the planer and “breaks or curls” the wood chips. The bot-
tom of the chipbreakers must be parallel to the knives and
set .040 below the cutting circle. To check and adjust the
chipbreakers, proceed as follows:
1. MAKE CERTAIN THE MACHINE IS DISCONNECT-
ED FROM THE POWER SOURCE.
2. Make certain the knives are adjusted properly as
explained in section “CHECKING, REPLACING AND RE-
SETTING KNIVES.”
3. Place gage block (B) Fig. 38, on the table surface and
directly under the cutterhead as shown. Using a .040
feeler gage (C) Fig. 38, placed on top of the gage block,
raise the table until cutterhead knife (D) touches the feeler
gage when the knife is at its lowest point. DO NOT MOVE
THE TABLE ANY FURTHER UNTIL THE ADJUSTMENT
HAS BEEN COMPLETED.
