GENERAL 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.
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.

19. 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.
20. DIRECTION OF FEED. Feed work into a blade or cutter
against the direction of rotation of the blade or cutter only.
21. NEVER LEAVE TOOL RUNNING UNATTENDED. TURN
POWER OFF. Don’t leave tool until it comes to a complete stop.
22.
STAY ALERT, WATCH WHAT YOU ARE DOING, and
use common sense when operating a power tool. DO NOT
USE TOOL WHILE TIRED OR UNDER THE INFLUENCE OF
DRUGS, ALCOHOL, OR MEDICATION. A moment of inat-
tention while operating power tools may result in serious personal injury.
23. MAKE SURE TOOL IS DISCONNECTED FROM POWER
SUPPLY while motor is being mounted, connected or reconnected.
24. 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.
25.
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.
SAVE THESE INSTRUCTIONS.
Refer to them often and use them to instruct others.

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 3-prong grounding
type plugs and matching receptacle which will 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.
WARNING: DO NOT EXPOSE THE TOOL TO RAIN OR OPERATE THE TOOL IN DAMP LOCATIONS.
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.
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 matching 3-conductor receptacles that accept
the tool’s plug, as shown in Fig. A.
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:
If the tool is intended for use on a circuit that has an outlet that
looks like the one illustrated in Fig. A, the tool 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.
WARNING: IN ALL CASES, MAKE CERTAIN THE
RECEPTACLE IN QUESTION IS PROPERLY
GROUNDED. IF YOU ARE NOT SURE, HAVE A
QUALIFIED ELECTRICIAN CHECK THE RECEPTACLE.

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