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 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 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. M AKE 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 balance
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.
17. DISCONNECT TOOLS before servicing and when
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 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.
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.
26. WARNING: The dust generated by certain woods and
wood products can be injurious to your health. Always oper¬
ate machinery in well ventilated areas and provide for proper
dust removal. Use wood dust collection systems whenever
possible.

ADDITIONAL SAFETY RULES FOR CIRCULAR SAWS
1. WARNING: Do not operate your saw until it is com¬
pletely assembled and installed according to the instruc¬
tions.
2. IF YOU ARE NOT thoroughly familiar with the opera¬
tion of circular saws, obtain advice from your supervisor,
instructor, or other qualified person.
3. ALWAYS use guard, splitter and anti-kickback fingers
on ail “thru-sawing" operations. Thru-sawing operations
are those when the blade cuts completely through the
workpiece as in ripping or cross-cutting.
4. ALWAYS hold the work firmly against the miter gage
or fence.
5. NEVER use the fence as a cut-off gage when cross¬
cutting.
6. MOVE the rip fence out of the way when cross¬
cutting.
7. NEVER perform any operation "free-hand” which
means using your hands to support or guide the work-
piece. Always use either the fence or miter gage to posi¬
tion and guide the work.
8. ALWAYS use a push stick for ripping narrow stock.
Refer to ripping applications in instruction manual where
the push stick is covered in detail.
9. AVOID kickbacks (work thrown back toward you) by:
A. Keeping blade sharp.
B. Keeping rip fence parallel to the saw blade.
C. Keeping splitter and anti-kickback fingers and
guard in place and operating.
D. Not releasing the work before it is pushed all the
way past the saw blade.
E. Not ripping work that is twisted or warped or does
not have a straight edge to guide along the fence.
10. AVOID awkward operations and hand positions where
a sudden slip could cause your hand to move into the
cutting tool.
11. ALWAYS keep hands and fingers away from the
blade.
12. NEVER stand or have any part of your body in line
with the path of the saw blade.
13. NEVER reach behind or over the cutting tool with
either hand for any reason.
14. DIRECTION OF FEED. Feed work into blade or cutter
against the direction or rotation of the blade or cutter
only.
15. DO NOT feed the material too fast while cutting.
Feed the material only fast enough so that the blade will
cut.
16. NEVER attempt to free a stalled saw blade without
first turning the saw “OFF.”
17. NEVER start the saw with the workpiece pressed
against the blade.
18. NEVER turn the saw “ON” before clearing the table
of all objects (tools, scraps of wood, etc.).
19. ALWAYS STOP the saw before removing scrap
pieces from the table.
20. NEVER perform layout, assembly or set-up work on
the table while the saw is operating.
21. PROVIDE adequate support to the rear and sides of
the saw table for wide or long workpieces.
22. WHEN cutting mouldings, NEVER run the stock be¬
tween the fence and the moulding cutterhead.
23. NEVER use solvents to clean plastic parts. Solvents
could possibly dissolve or otherwise damage the material.
Only a soft damp cloth should be used to clean plastic
parts.
24. SHOULD any part of your circular saw be missing,
damaged, or fail in any way, or any electrical components
fail to perform properly, shut off switch and remove plug
from power supply outlet. Replace missing, damaged or
failed parts before resuming operation.
25. ADDITIONAL INFORMATION regarding the safe
and proper operation of this product is available from the
National Safety Council, 1121 Spring Lake Drive, Itasca,
IL 60143-3201, in the Accident Prevention Manual for
Industrial Operations and also in the Safety Data Sheets
provided by the NSC. Please also refer to the American
National Standards Institute ANSI 01.1 Safety Require¬
ments for Woodworking Machinery and the U.S. Depart¬
ment of Labor OSHA 1910.213 Regulations.
26. SAVE THESE INSTRUCTIONS. Refer to them often
and use them to instruct others.
