Basic Saw Operations

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.

!WARNING 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

shackle of up to 3/16” in diameter (not provided with

 

 

compound miter saw) to prevent unauthorized use.
