OPERATION

TO MAKE NON-SLIDING CUTS

WARNING:

Securely tighten the slide lock knob when making any non-sliding cuts. Failure to tighten the knob could result in the saw head moving during the cutting operation.

TO MITER CUT / CROSS CUT

See Figures 33 - 34.

A cross cut is made by cutting across the grain of the workpiece. A straight cross cut is made with the miter table set at the 0° position. Miter cross cuts are made with the miter table set at some angle other than 0°.

Make sure the slide lock knob is tightened securely.

Raise saw arm to its full height.

Lift the miter lock lever to unlock. Rotate the miter table until the pointer aligns with the desired angle on the miter scale.

NOTE: You can quickly locate 0°, 15°, 22.5°, 31.6°, 45°, and 60° left or right by spinning the miter thumbwheel up. The lock plate will seat itself in one of the positive stop notches, located in the miter table base.

Push the miter lock lever down to lock the miter table.

Place the workpiece flat on the miter table with one edge securely against the fence. If the board is warped, place the convex side against the fence. If the concave edge of a board is placed against the fence, the board could collapse on the blade at the end of the cut, jamming the blade. See Figures 47 - 48.

When cutting long pieces of lumber or molding, support the opposite end of the stock with a roller stand or with a work surface level with the saw table. See Figure 40.

Align cutting line on the workpiece with the edge of saw blade.

Grasp the stock firmly with one hand and secure it against the fence. Use the work clamp or a C-clamp to secure the workpiece when possible.

Before turning on the saw, perform a dry run of the cut- ting operation to make sure that no problems will occur when the cut is made.

Grasp the saw handle firmly. Depress the switch lock with thumb then squeeze the switch trigger. Allow several seconds for the blade to reach maximum speed.

Slowly lower the blade into and through the workpiece.

Release the switch trigger and allow the saw blade to stop rotating before raising the blade out of workpiece and removing the workpiece from the miter table.
