GENERAL SAFETY RULES
1. FOR YOUR OWN SAFETY, READ THE INSTRUCTION
MANUAL BEFORE OPERATING THE MACHINE.
Learning the machine’s application, limitations, and
specific hazards will greatly minimize the possibility of
accidents and injury.
2. WEAR EYE PROTECTION. ALWAYS USE SAFETY
GLASSES. Also use face or dust mask if cutting
operation is dusty. Everyday eyeglasses are NOT safety
glasses. USE CERTIFIED SAFETY EQUIPMENT. Eye
protection equipment should comply with ANSI Z87.1
standards, hearing equipment should comply with
ANSI S3.19 standards, and dust mask protection
should comply with MSHA/NIOSH certified respirator
standards. Splinters, air-borne debris, and dust can
cause irritation, injury, and/or illness.
3. WEAR PROPER APPAREL. Do not wear loose
clothing, gloves, neckties, rings, bracelets, or other
jewelry which may get caught in moving parts. Nonslip
footwear is recommended. Wear protective hair
covering to contain long hair.
4. DO NOT USE THE MACHINE IN A DANGEROUS
ENVIRONMENT. The use of power tools in damp or
wet locations or in rain can cause shock or
electrocution. Keep your work area well-lit to prevent
tripping or placing arms, hands, and fingers in danger.
5. MAINTAIN ALL TOOLS AND MACHINES IN PEAK
CONDITION. Keep tools sharp and clean for best and safest
performance. Follow instructions for lubricating and changing
accessories. Poorly maintained tools and machines can further
damage the tool or machine and/or cause injury.
6. CHECK FOR DAMAGED PARTS. Before using the
machine, check for any damaged parts. Check for
alignment of moving parts, binding of moving parts,
breakage of parts, and any other conditions that may
affect its operation. A guard or any other part that is
damaged should be properly repaired or replaced.
Damaged parts can cause further damage to the
machine and/or injury.
7. KEEP THE WORK AREA CLEAN. Cluttered areas and
benches invite accidents.
8. KEEP CHILDREN AND VISITORS AWAY. Your shop is a
potentially dangerous environment. Children and visitors can
be injured.
9. REDUCE THE RISK OF UNINTENTIONAL STARTING.
Make sure that the switch is in the “OFF” position
before plugging in the power cord. In the event of a
power failure, move the switch to the “OFF” position.
An accidental start-up can cause injury.
10. USE THE GUARDS. Check to see that all guards are in
place, secured, and working correctly to prevent injury.
11. REMOVE ADJUSTING KEYS AND WRENCHES
BEFORE STARTING THE MACHINE. Tools, scrap
pieces, and other debris can be thrown at high speed,
causing injury.
12. USE THE RIGHT MACHINE. Don’t force a machine or
an attachment to do a job for which it was not
designed. Damage to the machine and/or injury may
result.
13. USE RECOMMENDED ACCESSORIES. The use of
accessories and attachments not recommended by
Delta may cause damage to the machine or injury to
the user.
14. USE THE PROPER EXTENSION CORD. Make sure
your extension cord is in good condition. When using
an extension cord, be sure to use one heavy enough
to carry the current your product will draw. An
undersized cord will cause a drop in line voltage,
resulting in loss of power and overheating. See the
Extension Cord Chart for the correct size depending
on the cord length and nameplate ampere rating. If in
doubt, use the next heavier gauge. The smaller the
gauge number, the heavier the cord.
15. SECURE THE WORKPIECE. Use clamps or a vise to
hold the workpiece when practical. Loss of control of
a workpiece can cause injury.
16. FEED THE WORKPIECE AGAINST THE DIRECTION OF
THE ROTATION OF THE BLADE, CUTTER, OR
ABRASIVE SURFACE. Feeding it from the other
direction will cause the workpiece to be thrown out at
high speed.
17. DON’T FORCE THE WORKPIECE ON THE MACHINE.
Damage to the machine and/or injury may result.
18. DON’T OVERREACH. Loss of balance can make you
fall into a working machine, causing injury.
19. NEVER STAND ON THE MACHINE. Injury could occur if
the tool tips, or if you accidentally contact the cutting tool.
20. NEVER LEAVE THE MACHINE RUNNING
UNATTENDED. TURN THE POWER OFF. Don’t leave the
machine until it comes to a complete stop. A child or visitor
could be injured.
21. TURN THE MACHINE “OFF”, AND DISCONNECT THE
MACHINE FROM THE POWER SOURCE before
installing or removing accessories, before adjusting
or changing set-ups, or when making repairs. An
accidental start-up can cause injury.
22. MAKE YOUR WORKSHOP CHILDPROOF WITH
PADLOCKS, MASTER SWITCHES, OR BY
REMOVING STARTER KEYS. The accidental start-
up of a machine by a child or visitor could cause
injury.
23. STAY ALERT, WATCH WHAT YOU ARE DOING,
AND USE COMMON SENSE. DO NOT USE THE
MACHINE WHEN YOU ARE TIRED OR UNDER
THE INFLUENCE OF DRUGS, ALCOHOL, OR
MEDICATION. A moment of inattention while
operating power tools may result in injury.
24. TAKE PRECAUTIONS AGAINST DUST
INHALATION. The dust generated by certain woods
and wood products can be injurious to your health.
Always operate machinery in well-ventilated areas,
and provide for proper dust removal. Use wood dust
collection systems whenever possible.
FAILURE TO FOLLOW THESE RULES MAY RESULT IN SERIOUS INJURY.

ADDITIONAL SAFETY RULES FOR SHARPENING CENTERS
1. DO NOT OPERATE THIS MACHINE until it is
completely assembled and installed according to the
instructions. A machine incorrectly assembled can
cause serious injury.
2. OBTAIN ADVICE from your supervisor, instructor, or
another qualified person if you are not thoroughly
familiar with the operation of this machine. Knowledge
is safety.
3. FOLLOW ALL WIRING CODES and recommended
electrical connections to prevent shock or
electrocution.
4. ALWAYS USE THE PROVIDED BLOTTER AND
WHEEL FLANGES to mount the grinding wheels on
the grinder shaft to prevent wheel damge or acciden-
tal separation. Separation can result in fragments
flying off the wheel at high speeds.
5. USE ONLY WHEELS suitable for the speed of the
machine. Unsuitable grinding wheels can come apart,
throwing fragments out at high speeds.
6. USE ONLY WHEELS that have a bore exactly equal
to the arbors of the machine. Never attempt to
machine an undersized wheel to fit an arbor.
Unsuitable grinding wheels can come apart, throwing
fragments out at high speeds.
7. DO NOT OVERTIGHTEN WHEEL NUT.
8. DO NOT USE A WHEEL THAT VIBRATES. Dress the
grinding wheel, replace it, or replace the bearings of
the shaft. Unsuitable grinding wheels can come apart,
throwing fragments at high speeds.
9. INSPECT WHEELS before starting the machine for
cracks or fragments. REPLACE DAMAGED WHEELS
immediately. Parts of the wheel can be thrown at high
speeds causing serious injury.
10. ADJUST EYE SHIELDS close to the grinding wheel,
and re-adjust as the wheel wears down. Flying sparks
are dangerous and can cause fires or explosions.
11. ALWAYS MAKE SURE the eye shields are in place,
properly adjusted, and secured.
12. ADJUST TOOL RESTS close to the grinding wheel
(1/8" separation or less). Tighten the tool rest securely
to prevent shifting positions, and re-adjust as the
wheel wears down. The workpiece can be drawn into
the wheel, causing damage to the workpiece and/or
serious injury.
13. STAND TO ONE SIDE before turning the machine
“ON”. Loose fragments or wheel parts could fly from
the wheel at high speeds.
14. NEVER GRIND ON A COLD WHEEL. Run the grinder
for one full minute before applying the workpiece. A
cold wheel has a tendency to chip. Those fragments
could fly from the wheel at high speeds.
15. NEVER START THE MACHINE with the workpiece
against the grinding wheel. The workpiece can be
drawn into the wheel, causing damage to the machine
and/or serious injury.
16. CLEAN THE MACHINE thoroughly when processing
different types of workpieces (wood, steel, or
aluminum). Combining wood and metal dust can
create an explosion or fire hazard. DO NOT GRIND
OR POLISH MAGNESIUM. Fire will result.
17. NEVER GRIND NEAR FLAMMABLE GAS OR
LIQUIDS. Sparks can create a fire or an explosion.
18. AVOID AWKWARD OPERATIONS AND HAND
POSITIONS. A sudden slip could cause a hand to
move into the grinding wheel.
19. KEEP ARMS, HANDS, AND FINGERS away from the
wheel. The abrasive surfaces can cause serious injury.
20. HOLD THE WORKPIECE FIRMLY against the tool
rest. Loss of control of the workpiece can cause
serious injury.
21. DRESS THE WHEEL on the face only. Dressing the
side of the wheel could cause it to become too thin
for safe use.
22. GRIND A WORKPIECE using the face of the grinding
wheel only. Loss of control of the workpiece can
cause serious injury.
23. NEVER APPLY COOLANT directly to the grinding
wheel. Coolant can weaken the bonding strength of
the grinding wheel and cause it to fail. Dip the
workpiece in water to cool it.
24. DO NOT TOUCH the ground portion of a workpiece
until it has cooled sufficiently. Grinding creates heat.
25. PROPERLY SUPPORT LONG OR WIDE WORK-
PIECES. Loss of control of the workpiece can cause
serious injury.
26. NEVER PERFORM LAYOUT, ASSEMBLY, or set-up
work on the table/work area when the machine is
running. A sudden slip could cause a hand to move
into the wheel. Severe injury can result.
27. TURN THE MACHINE “OFF”, disconnect the
machine from the power source, and clean the
table/work area before leaving the machine. LOCK
THE SWITCH IN THE “OFF” POSITION to prevent
unauthorized use. Someone else might accidentally
start the machine and cause serious injury to
themselves.

2. Grounded, cord-connected machines intended for use
on a supply circuit having a nominal rating less than 150
volts:
If the machine is intended for use on a circuit that has an
outlet that looks like the one illustrated in Fig. A,the
machine will have a grounding plug that looks like the plug
illustrated in Fig. A.A temporary adapter, which looks like
the adapter illustrated in Fig. B, may be used to connect
this plug to a matching 2-conductor receptacle as shown
in Fig. B if a properly grounded outlet is not available. The
temporary adapter should be used only until a properly
grounded outlet can be installed by a qualified electrician.
The green-colored rigid ear, lug, and the like, extending
from the adapter must be connected to a permanent
ground such as a properly grounded outlet box. Whenever
the adapter is used, it must be held in place with a metal
screw.
NOTE: In Canada, the use of a temporary adapter is not
permitted by the Canadian Electric Code.
IN ALL CASES, MAKE CERTAIN THE
RECEPTACLE IN QUESTION IS PROPERLY
GROUNDED. IF YOU ARE NOT SURE HAVE A
QUALIFIED ELECTRICIAN CHECK THE RECEPTACLE.
1. All grounded, cord-connected machines:
In the event of a malfunction or breakdown, grounding
provides a path of least resistance for electric current to
reduce the risk of electric shock. This machine is
equipped with an electric cord having an equipment-
grounding conductor and a grounding plug. The plug must
be plugged into a matching outlet that is properly installed
and grounded in accordance with all local codes and
ordinances.
Do not modify the plug provided - if it will not fit the outlet,
have the proper outlet installed by a qualified electrician.
Improper connection of the equipment-grounding
conductor can result in risk of electric shock. The
conductor with insulation having an outer surface that is
green with or without yellow stripes is the equipment-
grounding conductor. If repair or replacement of the
electric cord or plug is necessary, do not connect the
equipment-grounding conductor to a live terminal.
Check with a qualified electrician or service personnel if
the grounding instructions are not completely
understood, or if in doubt as to whether the machine is
properly grounded.
Use only 3-wire extension cords that have 3-prong
grounding type plugs and matching 3-conductor
receptacles that accept the machine’s plug, as shown in
Fig. A.
Repair or replace damaged or worn cord immediately.
POWER CONNECTIONS
MOTOR SPECIFICATIONS
Your machine is wired for 120 volts 60 HZ alternating current. Before connecting the machine to the power source,
make sure the switch is in the “OFF” position.
GROUNDING INSTRUCTIONS
THIS MACHINE MUST BE GROUNDED WHILE IN USE TO PROTECT THE OPERATOR FROM
ELECTRIC SHOCK.

EXTENSION CORDS
Use proper extension cords. Make sure your extension cord is in good condition and is a 3-wire
extension cord which has a 3-prong grounding type plug and matching receptacle which will accept the machine’s
plug. When using an extension cord, be sure to use one heavy enough to carry the current of the machine. An
undersized cord will cause a drop in line voltage, resulting in loss of power and overheating. Fig. D-1 or D-2, shows
the correct gauge to use depending on the cord length. If in doubt, use the next heavier gauge. The smaller the gauge
number, the heavier the cord.

planer knife using the dry wheel.
USING THE TOOL REST WITH
PLANER OR JOINTER KNIVES
1. Loosen four lock knobs (A) Fig. 52 and two screws
(E) and carefully slide knife (B) between the top and
bottom pieces (C) and (D) of the sliding tool rest. It is
important that the bevel edge of the knife (B) is in the
down position. Also, be sure the back of the knife is
pushed in so it sits against the knife adjustment bar
inside the tool rest.
2. Make sure knife (B) Fig. 52, protrudes out from the
top and bottom pieces (C) and (D) of the sliding tool
rest at least 5/16”. If it does not, rotate adjusting
knob (F) Fig. 50, clockwise to move the knife
outward or counterclockwise to move the knife in-
ward. When moving the knife inward, carefully push
the knife (B) inward with a piece of scrap wood while
turning the knob (F) counterclockwise. When you are
certain the knife protrudes 5/16” outward from the
sliding tool rest, tighten two screws (E) and four
knobs (A).
CARE MUST BE TAKEN WHEN
HANDLING PLANER OR JOINTER
KNIVES, AS THE CUTTING EDGES ARE VERY
SHARP. WEAR PROTECTIVE GLOVES WHEN
HANDLING THE KNIVES.
