* Confirm that the spindle lock has returned to the retract position after installing or
removing the saw blade.
* Tighten the bolt so it does not come loose during operation.
Confirm the bolt has been properly tightened before the power tool is started.
Never attempt to install saw blades larger than 12" (305mm) in diameter.
Always install saw blades that are 12" (305mm) in diameter or less.
Never use a dull saw blade. When a saw blade is dull, its resistance to the hand
pressure applied by the tool handle tends to increase, making it unsafe to operate
the power tool.
