FEATURES

MITER LOCK LEVER

See Figure 4.

The miter lock lever securely locks the saw at the desired 
miter angle. Push the lever down to lock the saw in place. 
To release the saw, lift the miter lock lever and depress the 
detent release button.

POSITIVE STOPS ON MITER TABLE

Positive stops have been provided at 0°, 15°, 22.5°, 31.6°, 
and 45°. The 0°, 15°, 22.5°, 31.6°, and 45° positive stops 
have been provided on both the left and right side of the 
miter table.

SELF-RETRACTING LOWER BLADE GUARD

The  lower  blade  guard  is  made  of  shock-resistant,  see-
through plastic that provides protection from each side of 
the blade. It retracts over the upper blade guard as the saw 
is lowered into the workpiece.

SPINDLE LOCK BUTTON

See Figure 5.

A  spindle  lock  button  has  been  provided  for  locking  the 
spindle which keeps the blade from rotating. Unplug the saw. 
Depress and hold the lock button while installing, changing, 
or removing blade only.

SLIDING MITER FENCES 

The sliding miter fences on your compound miter saw have 
been provided to help secure the workpiece when making 
cuts; the portion of the miter fence located farthest from the 
blade is larger to provide additional vertical support. 
The sliding feature makes it easy to remove or adjust the 
position of the fences and allow for clearance of the saw arm 
when making bevel or compound cuts. Loosen the fence 
screw before attempting to slide the miter fence. Once the 
desired position of the miter fence is determined, tighten the 
fence screw to secure the sliding fence.

SWITCH TRIGGER

See Figure 5.

To prevent unauthorized use of the compound miter saw, 
disconnect it from the power supply and lock the switch in 
the off position. To lock the switch, install a padlock (not 
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.
