OPERATION
LOCK-OFF BUTTON
See Figure 12.
The lock-off button reduces the possibility of accidental
starting. The lock-off button is located on the handle above
the switch trigger. The lock-off button must be depressed
before you pull the switch trigger. The lock resets each time
the trigger is released.
NOTE: You can depress the lock-off button from either the
left or right side.
STARTING/STOPPING THE SAW
See Figure 12.
To start the saw:
n Depress the lock-off button.
n Depress the switch trigger.
Always let the blade reach full speed, then guide the saw
into the workpiece.
WARNING:
The blade coming in contact with the workpiece
before it reaches full speed could cause the saw
to "kickback" towards you resulting in serious
injury.
To stop the saw: Release the switch trigger.
After you release the switch trigger, allow the blade to
come to a complete stop. Do not remove the saw from
the workpiece while the blade is moving.
DEPTH OF CUT ADJUSTMENT
See Figure 13.
Always keep correct blade depth setting. The correct blade
depth setting for all cuts should not exceed 1/4 in. below
the material to be cut. More blade depth will increase the
chance of kickback and cause the cut to be rough. One
blade tooth below the material to be cut works best for most
efficient cutting action.
TO ADJUST BLADE DEPTH
n Remove battery pack from saw.
n Loosen depth adjustment knob.
n Hold base flat against the workpiece and raise or lower
saw until the required depth is reached.
n Tighten depth adjustment knob securely.
