the information on the tool and in this operator’s manual as 
well as a knowledge of the project you are attempting. Before 
use  of  this  product,  familiarize  yourself  with  all  operating 
features and safety rules.

15 AMP MOTOR

This  saw  has  a  powerful  15  amp  motor  with  sufficient 
power to handle tough cutting jobs. It is made with all ball 
bearings,  and  has  externally  accessible  brushes  for  ease 
of servicing.

12 IN. BLADE

A 12 in. blade is included with your compound miter saw. It 
will cut materials up to 7-7/8 in. wide, depending upon the 
angle at which the cut is being made.

BLADE WRENCH STORAGE

A  blade  wrench  is  packed  with  this  saw.  One  end  of  the 
wrench is a phillips screwdriver and the other end is a hex 
key. Use the hex key end when installing or removing blade 
and the phillips end when removing or loosening screws. A 
storage area for the blade wrench is located in the saw's 
base.

For  convenience  when  carrying  or  transporting  the  miter 
saw from one place to another, a carrying handle has been

included) through the hole in the switch trigger. A lock with 
a long shackle up to 9/32 in. diameter may be used. When 
the lock is installed and locked, the switch is inoperable. 
Store the padlock key in another location.
