Auxiliary Fence - Certain types of molding need a fence face
extension because of the size and position of the workpiece.
Holes are provided in the fence to attach an auxiliary fence.
The auxiliary fence is used with the saw in the 0° bevel
position only.
1. Place a piece of wood 3 against the miter saw fence
(Figure 22). (Wood can have a maximum height as
high as the fence on the left. For the right side,
check that head assembly does not interfere with
auxiliary fence.)
2. Mark the locations of the support holes on the wood
from the back side of the fence.
3. Drill and countersink the holes on the front of the
support board.
4. Attach the auxiliary fence using four (4) flat head
machine screws 4. Make a full depth cut to create
the blade slot 5. Check for interference between the
auxiliary fence and the lower blade guard. Make
adjustments as necessary.
Check for interference from any
components.
Switch Activation
To reduce the likelihood of accidental start-up, the switch is
equipped with a safety button 6 that must be depressed
before the trigger 7 can be activated. The safety button is
designed to be activated by the right or left thumb. When the
safety button is depressed, the trigger is unlocked and it can
be pulled to activate the motor. Once the trigger is activated,
release the safety button so it can automatically engage and
lock the switch upon release of the trigger (Fig. 23).
NOTE: Switch can accommodate a padlock with a long
shackle of up to 3/16” in diameter (not provided with
compound miter saw) to prevent unauthorized use.
