OPERATION

WARNING:

Do not allow familiarity with tools to make you careless. Remember that a careless fraction of a second is sufficient to inflict severe injury.

WARNING:

Always wear safety goggles or safety glasses with side shields when operating tools. Failure to do so could result in objects being thrown into your eyes resulting in possible serious injury.

WARNING:

Do not use any attachments or accessories not recommended by the manufacturer of this tool. The use of attachments or accessories not recom- mended can result in serious personal injury.

APPLICATIONS

You may use this tool to cut only wood or plastic as listed below:

Cross cutting miters, joints, etc. for picture frames, mold- ings, door casings, and fine joinery

Bevel and compound cutting

Cross cutting wide workpieces

NOTE: The blade provided is fine for most wood cutting operations, but for fine joinery cuts or cutting plastic, use one of the accessory blades available from the RIDGID dealer.

WARNING:

Before starting any cutting operation, clamp or bolt the miter saw to a workbench. Never operate the miter saw on the floor or in a crouched position. Failure to heed this warning can result in serious personal injury.

WARNING:

To avoid serious personal injury, always tighten the miter lock lever and the bevel lock lever securely before making a cut. Failure to do so could result in movement of the saw arm or miter table while making a cut.

WARNING:

To avoid serious personal injury, keep your hands outside the no hands zone, at least 3 in. from blade. Never perform any cutting operation freehand (with- out holding workpiece against the fence). The blade could grab the workpiece if it slips or twists.

CAUTION:

Do not start the compound miter saw without checking for interference between the blade and the miter fence. Damage could result to the blade if it strikes the miter fence during operation of the saw.

CUTTING WITH YOUR COMPOUND MITER SAW

WARNING:

When using a work clamp or C-clamp to secure the workpiece, clamp workpiece on one side of the blade only. The workpiece must remain free on one side of the blade to prevent the blade from binding in workpiece. The workpiece binding the blade will cause motor stalling and kickback. This situation could cause an accident resulting in possible seri- ous personal injury.

WARNING:

NEVER move the workpiece or make adjustment to any cutting angle while the saw is running and the blade is rotating. Any slip can result in contact with the blade causing serious personal injury.
