Saw Operations

Crown Molding Auxiliary fence

When making a compound cut on a ! WARNING molding lying flat on the table,

narrow cut-off pieces (2" or less in width) may be propelled at high speed over the fence and beyond the back of the tool (see figure 50). Use auxiliary fence as instructed and shown in figures below.

A crown molding auxiliary fence is used to add support to the cut-off workpiece such as large crown molding when cut flat on the table (see figure 51). It will reduce splintering and movement of the unsupported cut-off piece of wood after the cut is made.

Making Crown Molding Auxiliary fence

Required pieces:

3/4” thick wood board

4 – Flat Head Machine Screws 1/4"diameter x 2-1/2" long

4 – 1/4" Flat Washers

4 – 1/4" Nuts

1.Remove the sliding fence from the tool (see page 26).

2.Build auxiliary fence by following the pattern and illustrations on page 39.

3.Add 4 holes as dimensioned on pattern -or- add holes following the next steps:

a.Cut wood to the outside dimensions shown and temporarily attach to saw’s stationary fence using two C-clamps.

b.Use 1/4" drill bit to drill first through existing holes in the rear of the stationary fence and then through the wood.

c.Remove wood, countersink the front of the wood and permanently attach to saw’s fence with hardware shown below.

first-Time Use of the Auxiliary fence

NOTE: The first time the auxiliary fence is used, it will be cut through by the saw blade – cutting through creates minimal clearance which reduces splintering on the workpiece. Set the miter angle and the bevel angle required before making the first cut.

Be aware of the path of the saw ! WARNING blade. Make a dry run with the saw

Off by conducting a simulated cutting cycle, and observe the projected path of the saw blade. Keep hands at least six (6) inches away from the projected path of the saw blade.

Clamp the workpiece, then make cut – example: compound cutting large crown molding flat on the table.
