WARNING:

Read and understand all instructions. 

Failure to 

follow all instructions listed below, could result in 
electric shock, fire and/or serious personal injury.

READ ALL INSTRUCTIONS

 

KNOW YOUR POWER TOOL. 

Read the operator’s manual 

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

 

GUARD AGAINST ELECTRICAL SHOCK BY PREVENT-
ING BODY CONTACT WITH GROUNDED SURFACES. 

For example: pipes, radiators, ranges, refrigerator enclo-
sures.

 

KEEP GUARDS IN PLACE 

and in good working order.

 

REMOVE ADJUSTING KEYS AND WRENCHES. 

Form 

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

 

KEEP WORK AREA CLEAN. 

Cluttered areas and benches 

invite accidents.

 DO NOT

 leave tools or pieces of wood 

on the tool while it is in operation.

 

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.

 

KEEP  CHILDREN  AND  VISITORS  AWAY. 

All  visitors 

should  wear  safety  glasses  and  be  kept  a  safe  dis-
tance from work area. Do not let visitors contact tool or

  extension cord while operating.

 

MAKE  WORKSHOP  CHILDPROOF 

with  padlocks, 

master switches, or by removing starter keys.

 

DON’T FORCE THE TOOL.

 It will do the job better and 

safer at the feed rate for which it was designed.

 

USE THE RIGHT TOOL.

 Do not force the tool or attach-

ment to do a job for which it was not designed.

 

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 result-
ing 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.

 

DRESS PROPERLY.

 Do not wear loose clothing, neckties, 

or jewelry that can get caught and draw you into moving 
parts. Rubber gloves and nonskid footwear are recom-
mended when working outdoors. Also wear protective 
hair covering to contain long hair.

  ALWAYS  WEAR  SAFETY  GLASSES  WITH  SIDE 

SHIELDS.

  Everyday  eyeglasses  have  only  impact-

  resistant lenses, they are 

NOT

 safety glasses.

GENERAL SAFETY RULES

 

SECURE WORK. 

Use clamps or a vise to hold work when 

practical, it is safer than using your hand and frees both 
hands to operate the tool.

 

DO NOT OVERREACH.

 Keep proper footing and balance 

at all times.

 

MAINTAIN TOOLS WITH CARE. 

Keep tools sharp and 

clean for better and safer performance. Follow instruc-
tions for lubricating and changing accessories.

 

DISCONNECT TOOLS. 

When not in use, before servicing, 

or when changing attachments, blades, bits, cutters, etc., 
all tools should be disconnected from power source.

 

AVOID ACCIDENTAL STARTING. 

Be sure switch is off 

when plugging in any tool.

operator’s  manual  for  recommended  accessories.  The 
use of improper accessories may result in injury.

 

NEVER STAND ON TOOL. 

Serious injury could occur if 

the tool is tipped.

 

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.

 

USE THE RIGHT DIRECTION OF FEED. 

Feed work into 

a blade, cutter, or sanding spindle against the direction 
or rotation of the blade, cutter, or sanding spindle only.

 

NEVER LEAVE TOOL RUNNING UNATTENDED. TURN 
THE POWER OFF. 

Don’t leave tool until it comes to a 

complete stop.

 

PROTECT YOUR LUNGS. 

Wear a face or dust mask if 

the cutting operation is dusty.

yank it to disconnect from receptacle. Keep cord from 
heat, oil, and sharp edges.

  When  tool  is 

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

KEEP BLADES CLEAN, SHARP, AND WITH SUFFICIENT 
SET.
