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 possibility 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 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 application, 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. REMOVE ADJUSTING KEYS AND WRENCHES. Form

habit of checking to see that keys and adjusting wrenches
are removed from tool before turning it “on”.

5. KEEP WORK AREA CLEAN. Cluttered areas and

benches invite accidents.

6. 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.

7. KEEP CHILDREN AND VISITORS AWAY. All children

and visitors should be kept a safe distance from work area.

8. MAKE WORKSHOP CHILDPROOF – with padlocks,

master switches, or by removing starter keys.

safer at the rate for which it was designed.

10. USE RIGHT TOOL. Don’t force tool or attachment to
do a job for which it was not designed.

11. 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.

12.

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. These safety glasses
must conform to ANSI Z87.1 requirements. Note:
Approved glasses have Z87 printed or stamped on them.

13. 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.

14. DON’T OVERREACH. Keep proper footing and
balance at all times.

15. MAINTAIN TOOLS IN TOP CONDITION. Keep tools
sharp and clean for best and safest performance. Follow
instructions for lubricating and changing accessories.

16. DISCONNECT TOOLS before servicing and when
changing accessories such as blades, bits, cutters, etc.

17. USE RECOMMENDED ACCESSORIES. The use of
accessories and attachments not recommended by Delta
may cause hazards or risk of injury to persons.

18. REDUCE THE RISK OF UNINTENTIONAL
STARTING. Make sure switch is in “OFF” position before
plugging in power cord.

19. NEVER STAND ON TOOL. Serious injury could occur if
the tool is tipped or if the cutting tool is accidentally
contacted.

20. CHECK DAMAGED PARTS. Before further use of the
tool, a guard or other part that is damaged should be
carefully checked to ensure that it will operate properly and
perform its intended function – check for alignment of
moving 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.

21. DIRECTION OF FEED. Feed work into a blade or
cutter against the direction of rotation of the blade or cutter
only.

22. NEVER LEAVE TOOL RUNNING UNATTENDED.
TURN POWER OFF. Don’t leave tool until it comes to a
complete stop.

23. DRUGS, ALCOHOL, MEDICATION. Do not operate
tool while under the influence of drugs, alcohol or any
medication.

24. MAKE SURE TOOL IS DISCONNECTED FROM
POWER SUPPLY while motor is being mounted,
connected or re-connected.

25. 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.

26.

WARNING: SOME DUST CREATED BY POWER
SANDING, SAWING, GRINDING, DRILLING, AND
OTHER CONSTRUCTION ACTIVITIES contains

chemicals known to cause cancer, birth defects or other
reproductive harm. Some examples of these chemicals are:

• lead from lead-based paints,

• crystalline silica from bricks and cement and other

masonry products, and

• arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how
often you do this type of work. To reduce your exposure
to these chemicals: work in a well ventilated area, and
work with approved safety equipment, such as those
dust masks that are specially designed to filter out
microscopic particles.

ADDITIONAL SAFETY RULES FOR

GRINDERS

3

1. DO NOT operate your tool until it is completely
assembled and installed according to the instructions.

2. IF YOU ARE NOT thoroughly familiar with the opera-
tion of grinders, obtain advice from your supervisor,
instructor or other qualified person.

3. USE only grinding wheels rated for 3600 RPM with a
5/8" or 1" arbor hole, for Models 23-730 & 23-725.
NEVER use a wheel rated lower than 3600 RPM for
Model 23-730, NEVER use a wheel rated lower than 1800
RPM for Model 23-725, or attempt to machine an
undersize wheel to fit an arbor. Model 23-735 uses
grinding wheels rated for 1800 RPM with a 3/4" or 1-1/4"
arbor hole. NEVER use a wheel rated lower than 1800
RPM for Model 23-735.

4. NEVER use a chipped or cracked grinding wheel.
ALWAYS inspect each wheel before mounting on the
grinder. REPLACE A CRACKED WHEEL IMMEDI-

AT ELY.

5. DO NOT overtighten wheel nut.

6. FREQUENTLY clean grinding dust from beneath the
grinder.

7. ALWAYS maintain a distance of 1/8" or less between
the grinding wheel and the tool rest. Adjust the tool rests
as the grinding wheels decrease in size with use.

8. SECURELY tighten tool rests so they cannot shift
position while in use.

9. NEVER grind on a cold wheel. The grinder should
always be started and run at idle speed for one full minute
before applying work.

10. NEVER grind on the side of the wheel. ALWAYS
grind on the face of the wheel only.

11. NEVER apply coolant directly to a grinding wheel.
Coolant can weaken the bonding strength of the wheel
and cause it to fail. Dip the workpiece into water to cool
it.

12. SPARKS ARE A HAZARD! NEVER grind near flam-
mable gas or liquids.

13. ALWAYS MAKE SURE the wheel guards and eye
shields are in place, properly adjusted and secured.

14. KEEP the spark guards close to the wheel and re­adjust them as the wheel wears.

15. MAKE CERTAIN the blotter and wheel flanges fur-
nished are used to mount the grinding wheels onto the
grinder shaft.

16. THE USE of attachments and accessories not
recommended by Delta may result in the risk of injuries.

17. STAND to one side of the wheel when turning on the
power.

18. AVOID awkward hand positions where a sudden slip
could cause a hand to move into the grinding wheel.

19. ALWAYS keep hands and fingers away from the
grinding wheel.

20. NEVER start the grinder with the workpiece pressed
against the grinding wheel.

21. DRESS the wheel on the face only. Dressing the side
of the wheel can cause it to become too thin for safe use.

22. DO NOT use a wheel that vibrates. Dress the wheel,
replace the wheel, or replace the shaft bearings, if worn.

23. GRINDING CREATES HEAT. Do not touch the work-
piece until you are sure it has cooled sufficiently.

24. YOUR TOOL may start after a power failure. DO
NOT use in an area where children may be present.

25. ALWAYS keep guards in place when using a wire
brush or buffing wheel in place of the standard grinding
wheel.

26. SHOULD any part of your grinder be missing, dam­aged, or fail in any way, or any electrical component fail
to perform properly, shut off switch and remove plug
from power supply outlet. Replace missing, damaged or
failed parts before resuming operation.

27. ADDITIONAL information regarding the safe and
proper operation of this product is available from the

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 a 3-pole
receptacle which will accept the tool’s plug. When using
an extension cord, be sure to use one heavy enough to
carry the current of the saw. An undersized cord will
cause a drop in line voltage, resulting in loss of power
and overheating. Fig. 14, 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.

CONNECTING TOOL TO POWER SOURCE

POWER CONNECTIONS

A separate electrical circuit should be used for your tools. This circuit should not be less than #12 wire and should be
protected with a 20 Amp time lag fuse. If an extension cord is used, use only 3-wire extension cords which have 3­prong grounding type plugs and 3-pole receptacles which accept the tool’s plug. Before connecting the motor to the
power line, make sure the switch is in the “OFF” position and be sure that the electric current is of the same
characteristics as indicated on the tool. All line connections should make good contact. Running on low voltage will
damage the motor.

MOTOR SPECIFICATIONS

Your tool is wired for 120 volt, 60 HZ alternating current. Before connecting the tool to the power source, make sure
the switch is in the “OFF” position. The motor for the 23-725 & 23-735 provides a no-load speed of 1725 RPM. The
motor for the 23-730 provides a no-load speed of 3450 RPM.

GROUNDING INSTRUCTIONS

WARNING: THIS TOOL MUST BE GROUNDED WHILE IN USE TO PROTECT THE OPERATOR FROM
ELECTRIC SHOCK.

1. All grounded, cord-connected tools: 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 tool 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 tool is properly grounded.

Use only 3-wire extension cords that have 3-prong grounding type plugs and 3-pole receptacles that accept the tool’s
plug, as shown in Fig. 15.

Repair or replace damaged or worn cord immediately.

2. Grounded, cord-connected tools intended for use on
a supply circuit having a nominal rating less than 150
volts:

This tool is intended for use on a normal 120-volt circuit
and has a grounded plug that looks like the plug
illustrated in Fig. 15.

If a properly grounded outlet is not available, a temporary
adapter, shown in Fig. 16, may be used for connecting the
3-prong grounding type plug to a 2-pole receptacle. 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, or the like extending from
the adapter must be connected to a permanent ground
such as a properly grounded outlet box cover. 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.

WARNING: IN ALL CASES, MAKE CERTAIN
THE RECEPTACLE IN QUESTION IS PROPERLY
GROUNDED. IF YOU ARE NOT SURE HAVE A
CERTIFIED ELECTRICIAN CHECK THE RECEPTACLE.

FLEXIBLE LAMP

The flexible lamp operates independently of the grinder.
To turn the lamp on and off, rotate switch (A) Fig. 17.

WARNING: To reduce the risk of fire, use 40 watt
or less, 120 volt, reflector track type light bulb (not
supplied). A standard household light bulb should
not be used. The reflector track type light bulb
should not extend below the lampshade.

GRINDING WHEELS

WARNING: THE USE OF ACCESSORIES AND
ATTACHMENTS NOT RECOMMENDED BY DELTA
MAY RESULT IN RISK OF INJURIES. Grinding wheels

used with Model 23-730 grinders should be rated for
3600 RPM or higher and be 8" in diameter with a 5/8" or
1" arbor hole. Grinding wheels used with Model 23-725
grinders should be rated for 1800 RPM or higher and be
8" in diameter with a 5/8" or 1" arbor hole. Grinding
wheels used with Model 23-735 grinder should be rated
for 1800 RPM or higher and be 10" in diameter with a
3/4" or 1-1/4" arbor hole.

The arbor bushing should be saved, for future use, if the
replacement wheel does not use the bushing.

For best grinding results, and to maintain good balance,
always keep the wheels properly dressed. Do not force
the work against a cold wheel. The grinding wheel
should always be run at idle speed for one full minute
before applying work. It is recommended that only
balanced wheels be used with your grinder. The use of
balanced wheels adds years to the life of the bearings
on the grinder and by eliminating the most common
source of vibration, more accurate work is
accomplished.

DRESSING A GRINDING WHEEL

When dressing a grinding wheel, use a suitable silicone
carbide stick type dresser or the wheel dresser wrench
provided with the grinder, as shown in Fig. 19. Bring the
dresser forward on the tool rest until it just touches the
high point on the face of the wheel and dress the wheel
by moving the dresser back and forth. Repeat this
operation until the face of the grinding wheel is clean
and the corners of the wheels are square.

OPERATIONS

IMPORTANT: KEEP SPARK GUARDS AND EYE
SHIELDS IN PLACE AT ALL TIMES.

Figures 23, 24, and 25, illustrate several typical
operations that can be accomplished using the grinder.
Each tool rest should be positioned a little below the
center of the grinding wheel and adjusted so the edge of
the tool rest is as close as possible to the grinding wheel
for maximum support to the piece that is being ground.
This is the most practical and safest position for general
work.

As the grinding wheel wears down to a smaller diameter,
readjust the tool rest closer to the grinding wheel. Always
maintain a distance of 1/8" or less between the grinding
wheel and the edge of the tool rest. Free hand grinding
without the use of the tool rest should always be done on
the lower quarter of the grinding wheel. Please read the
“SAFETY RULES” in the front of this manual and follow
them while operating this tool.
