Never start the power tool when any rotating component is in contact with

WARNING:USE OF THIS TOOL CAN GENERATE AND DISBURSE DUST OR
OTHER AIRBORNE PARTICLES, INCLUDING WOOD DUST, CRYSTALLINE SILICA DUST
AND ASBESTOS. Direct particles away from face and body. Always operate tool in a
well-ventilated area and provide for proper dust removal. Use dust collection system
wherever possible. Exposure to the dust may cause serious and permanent respiratory
or other injury, including silicosis (a serious lung disease), cancer, and death. Avoid
breathing the dust, and avoid prolonged contact with the dust. Allowing dust to get into
your mouth or eyes, or lay on your skin may promote absorption of harmful material.
Always use properly fitting NIOSH/OSHA approved respiratory protection appropriate for
dust exposure, and wash exposed areas with soap and water.

UNPACKING AND CONTENTS
IMPORTANT:Due to modern mass production techniques, it is unlikely the tool is
faulty or that a part is missing. If you find anything wrong, do not operate the tool until
the parts have been replaced or the fault has been rectified. Failure to do so could result
in serious personal injury.

have read and understand the entire operator’s manual.
WARNING: Be sure that the tool is switched off and unplugged from the
power source before performing any work on the tool. Failure to unplug the saw may
result in accidental start-up, causing possible serious personal injury.

source before performing any work on the tool.
WARNING: Use only 12 inch diameter saw blades and are rated for speeds
equal to or greater then the nameplate rated RPM of this miter saw.
WARNING: Use only blades designed forcross-cutting operations.
WARNING: Do not use thin kerf blades with deep gullets which may deflect
and contact the blade guards or produce poor quality cuts in the workpiece.

WARNING: After completing a cut, release the trigger switch to activate the
electric blade brake. Keep the cutting head down until the blade comes to a complete
stop before raising the cutting head to the upward or starting position. A rotating saw
blade can be dangerous.
WARNING: The torque resulting from electric blade brake activation may
loosen the arbor bolt. Occasionally check the arbor bolt and tighten if necessary.

APPLICATION
TYPICAL COMPOUND MITER SAW OPERATIONS
WARNING: Always be sure the miter saw is disconnected from the power
source before making any adjustments or during set-up prior to cutting. Failure to
disconnect or unplug the machine may cause accidental starting, resulting in serious
personal injury.
WARNING: Be sure the miter saw is securely bolted down or clamped to a
workbench or appropriate work surface before performing any cutting operations.
Failure to do so may result in loss of machine control and/or result in personal injury.
WARNING: If securely holding the workpiece causes your hand to be in the
machine’s “Hazard Zone”, clamp the workpiece in place and move your hand(s) to a
safe position before making the cut.
