6 .  Check for loose screws, misalignment  
      or binding of moving parts, or any other  
     condition that may affect the operation .
7 .  If abnormal vibration or noise occurs,    
    turn the saw off immediately, and have  
   the problem corrected before further 
      use .

SERVICE OF LASER GUIDE

Use a soft paintbrush or similar device to  
remove all sawdust and debris . (Compressed 
air contains fine oil droplets that adhere to 
the lens . Therefore, you should not blow  
out the lens with compressed air) .

SAWDUST

Periodically, sawdust will accumulate under 
the worktable and base . This could cause 
difficulty in the movement of the worktable 
when setting up a miter cut . Frequently blow 
out or vacuum up the sawdust .

                                 

Always wear safety 

goggles or safety glasses with side 
shields during power tool operations or 
when blowing dust. If operation is dusty, 
also wear a dust mask.

LOWER bLADE GUARD

                                 DO NOT use the saw 
without the lower blade guard. The lower 
blade guard is attached to the saw for 
your protection. Should the lower blade 
guard become damaged, do not use the 
saw until the damaged guard has been 
replaced. Check the lower blade guard 
regularly; making certain that it is in 
proper working order.

                                 When cleaning the 
lower blade guard, unplug the saw from 
the power source receptacle to avoid 
unexpected start up.

MAINTENANCE

    WARNING:                     

    WARNING:                     

    CAUTION:                     

NOTICE: Do not use solvents on the 
guard, as they may cause any plastic 
parts to become “cloudy” or brittle.

REMOVING THE bLADE 

(FIG. 38-39)

                                 To reduce the risk 
of injury, always unplug the tool before 
removing or installing a blade.

1 .   Unplug the tool .
2 .   Raise the saw head, lift and hold lower  
      blade guard .
3 .   Loosen the screw by screwdriver to a   
   point that arbor screw guard can be 
      lifted .
4 .   Lift and hold the lower blade guard up,  
   and rotate the blade-screw guard to 

 

      expose the threaded blade screw .
5 .   Press and hold the spindle-lock button,  
    and rotate the blade at the same time  
      until it locks into position .
6 .   Use the blade wrench (included) to turn  
   the threaded blade screw clockwise, 

 

   and then remove the threaded blade 

 

      screw .
7 .   Remove the outer flange and the blade .  
      Wipe the flanges and spindle to remove  
      any dust and debris .
