GENERAL SAFETY RULES

   

WARNING:

 

Read and understand all instruc-

tions.

 Failure to follow all instructions listed below, 

may result in electric shock, fire and/or serious 

personal injury.

READ ALL INSTRUCTIONS

n

 

KNOW YOUR POWER TOOL. 

Read the operator's 

manual carefully. Learn the saw's applications and
limitations as well as the specific potential hazards 
related to this tool.

n

 

GUARD AGAINST ELECTRICAL SHOCK BY PRE-
VENTING BODY CONTACT WITH GROUNDED 
SURFACES. 

For example, pipes, radiators, ranges, 

refrigerator enclosures.

n

 

KEEP GUARDS IN PLACE 

and in good working order.

n

 

REMOVE ADJUSTING KEYS AND WRENCHES. 

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

n

 

KEEP WORK AREA CLEAN. 

Cluttered areas and 

benches invite accidents.

 DO NOT

 leave tools or 

pieces of wood on the saw while it is in operation.

n

 

DO NOT USE IN DANGEROUS ENVIRONMENTS.

 

Do not use power tools in damp or wet locations or 
expose to rain. Keep the work area well lit.

n

 

KEEP CHILDREN AND VISITORS AWAY. 

All visitors 

should wear safety glasses and be kept a safe
distance from work area. Do not let visitors contact tool 
or extension cord while operating.

n

 

MAKE WORKSHOP CHILDPROOF 

with padlocks and 

master switches, or by removing starter keys.

n

 

DON'T FORCE TOOL.

 It will do the job better and 

safer at the feed rate for which it was designed.

n

 

USE RIGHT TOOL.

 Don't force the tool or attachment 

to do a job it was not designed for. Don't use it for a 
purpose not intended.

n

 

USE THE PROPER EXTENSION CORD. 

Make sure 

your extension cord is in good condition. Use only a 
cord 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. A 
wire gauge size (A.W.G.) of at least 

14

 is recommended 

for an extension cord 25 feet or less in length. If in 
doubt, use the next heavier gauge. The smaller the 
gauge number, the heavier the cord.

n

 

DRESS PROPERLY.

 Do not wear loose clothing, 

gloves, neckties, or jewelry. They can get caught 
and draw you into moving parts. Rubber gloves and 
nonskid footwear are recommended when working 
outdoors. Also wear protective hair covering to contain 
long hair.

n

  ALWAYS WEAR SAFETY GLASSES WITH SIDE 

SHIELDS.

 Everyday eyeglasses have only impact-

resistant lenses, they are 

NOT

 safety glasses.

n

 

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.

n

 

DON'T OVERREACH.

 Keep proper footing and

balance at all times.

n

 

MAINTAIN TOOLS WITH CARE. 

Keep tools sharp

and clean for better and safer performance. Follow 
instructions for lubricating and changing accessories.

n

 

DISCONNECT TOOLS. 

When not in use, before

servicing, or when changing attachments, blades, bits, 
cutters, etc., all tools should be disconnected.

n

 

AVOID ACCIDENTAL STARTING. 

Be sure switch is off 

when plugging in any tool.

n

 

USE RECOMMENDED ACCESSORIES. 

The use of 

improper accessories may risk injury.

n

 

NEVER STAND ON TOOL. 

Serious injury could occur 

if the tool is tipped or if the cutting tool is unintention-
ally contacted.

n

 

CHECK DAMAGED PARTS. 

Before further use of 

the tool, a guard or other part that is damaged should 
be carefully checked to determine 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 must be properly repaired or replaced by 
an authorized service center to avoid risk of personal 
injury.

n

 

USE THE RIGHT DIRECTION OF FEED. 

Feed work 

into a blade or cutter against the direction of rotation of 
blade or cutter only.

n

 

NEVER LEAVE TOOL RUNNING UNATTENDED. 
TURN THE POWER OFF. 

Don't leave tool until it 

comes to a complete stop.

n

 

PROTECT YOUR LUNGS. 

Wear a face or dust mask if 

the cutting operation is dusty.

n

 

PROTECT YOUR HEARING. 

Wear hearing protection 

during extended periods of operation.

n

 

DO NOT ABUSE CORD.

 Never yank cord to discon-

nect from receptacle. Keep cord from heat, oil, and 
sharp edges.

n

 

USE OUTDOOR EXTENSION CORDS.

 When tool is 

used outdoors, use only extension cords with ap-
proved ground connection that are intended for use 
outdoors and so marked.

KEEP BLADES CLEAN, SHARP, AND WITH  SUF-
FICIENT SET.

 Sharp blades minimize stalling and 

kickback.

BLADE COASTS AFTER BEING TURNED OFF.

n

 

NEVER USE IN AN EXPLOSIVE ATMOSPHERE.

Normal sparking of the motor could ignite fumes.
