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.

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.

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.

9. DON’T FORCE TOOL. It will do the job better and be

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. 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.

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

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

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

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

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

In the event of a power failure, move switch

to the “OFF” position.

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

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 inattention 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.

THREE PHASE
INSTALLATION

If the motor on your machine is wired for 200V, 230V, or
460V, three phase, the necessary wiring from the starter to
the power should be completed by a qualified electrician.

Permanently connected machines:
This machine should be connected to a grounded metal
permanent wiring system; or to a system having a
equipment-grounding conductor. These connections
should be made by a qualified electrician.

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.

SINGLE PHASE
INSTALLATION

If the motor on your machine is wired for 115 voIt, single
phase, the power cord is equipped with a plug that has
two flat, parallel current-carrying prongs and one longer
round or "U"-shaped, ground prong Which requires a
mating 3-conductor grounded type receptacle, as shown
in Fig. A.

If the motor on your machine is wired for 230 Volt, single
phase, the power cord is equipped with a plug that has
two flat, current-carrying prongs in tandem, and one
round or "U" shaped longer ground prong. This is used
only with the proper mating 3-conductor grounding type
receptacle, as shown in Fig. B.

When the three-prong plug on your machine is plugged
into a grounded 3-conductor receptacle, the long ground
prong on the plug contacts first so the machine is
properly grounded before electricity reaches it.
