OPERATION

MITER THUMBWHEEL

The miter thumbwheel, when used with the miter lock lever lifted (unlocked), can release the miter table from pre-set index points.

To align with miter scale:

Lift the miter lock lever to unlock.

Rotate and hold thumbwheel so that the yellow dot on the thumbwheel aligns with indicator point (white dot) on the miter lock lever to override index points.

When close to desired angle, release the thumbwheel. NOTE: When the orange dot on the thumbwheel clicks into place (aligned with the indicator point), the miter table is locked into a preset index point.

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

To bypass preset index points:

Lift the miter lock lever to unlock.

Rotate the thumbwheel so that the white dot on the thumbwheel aligns with the indicator point (white dot) on the miter lock lever.

TO MITER CUT / CROSS CUT

See Figures 28 - 29.

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°.

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°, and 45° left or right by spinning the miter thumbwheel up. The lock plate will seat itself in one of the index points 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 40 - 41.

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 35.

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. Squeeze the switch trigger. Allow several seconds for the blade to reach maximum speed.
