SPECIFIC SAFETY RULES

 

NEVER

 hand hold a workpiece that is too small to be 

clamped. Keep hands clear of the cutting area.

 

NEVER

 reach behind, under, or within three inches of the 

blade and its cutting path with your hands and fingers for 
any reason.

 

NEVER

 reach to pick up a workpiece, a piece of scrap, 

or anything else that is in or near the cutting path of the 
blade.

 

AVOID

 

AWKWARD  OPERATIONS  AND  HAND 

POSITIONS 

where  a  sudden  slip  could  cause  your 

hand to move into the blade. 

ALWAYS 

make sure you 

have  good  balance. 

NEVER

  operate  your  miter  saw 

on the floor or in a crouched position.

 

NEVER

 stand or have any part of your body in line with 

the path of the saw blade.

 

ALWAYS 

release the power switch and allow the saw blade 

to stop rotating before raising it out of the workpiece.

 

DO NOT TURN THE MOTOR SWITCH ON AND OFF 
RAPIDLY. 

This  could  cause  the  saw  blade  to  loosen 

and  could  create  a  hazard.  Should  this  ever  occur, 
stand  clear  and  allow  the  saw  blade  to  come  to  a 
complete  stop.  Disconnect  your  saw  from  the  power 
supply and securely retighten the blade bolt.

  IF  ANY  PART  OF  THIS  MITER  SAW  IS  MISSING 

or 

should  break,  bend,  or  fail  in  any  way,  or  should  any 
electrical component fail to perform properly, shut off  
the power switch, remove the miter saw plug from the 
power source and have damaged, missing, or failed parts 
replaced before resuming operation.

 

IF THE POWER SUPPLY CORD IS DAMAGED, 

it must 

be replaced only by the manufacturer or by an authorized 
service center to avoid risk.

 

ALWAYS STAY ALERT!

 Do not allow familiarity (gained 

from frequent use of your saw) to cause a careless mis-
take. 

ALWAYS REMEMBER 

that a careless fraction of 

a second is sufficient to inflict severe injury.

 

MAKE SURE THE WORK AREA HAS AMPLE LIGHTING

 

to see the work and that no obstructions will interfere with 
safe operation 

BEFORE

 performing any work using your 

saw.

 

ALWAYS TURN OFF THE SAW 

before disconnecting it 

to avoid accidental starting when reconnecting to power 
supply. 

NEVER 

leave the saw unattended while connected 

to a power source.

 

THIS TOOL 

should have the following markings:

  a)  Wear eye protection.
  b)  Keep hands out of path of saw blade.
  c)  Do not operate saw without guards in place.
  d)  Do not perform any operation freehand.
  e)  Never reach around saw blade.
  f)  Turn off tool and wait for saw blade to stop before 

 

moving workpiece or changing settings.

  g)  Disconnect  power  (or  unplug  tool  as  applicable) 

 

before changing blade or servicing.

  h)  No load speed.

 

ALWAYS 

carry the tool only by the carrying handle.

 

AVOID 

direct eye exposure when using the laser guide.

 

SAVE  THESE  INSTRUCTIONS.

  Refer  to  them  

frequently  and  use  to  instruct  other  users.  If  you  loan 
someone this tool, loan them these instructions also.

 

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.
