Operator’s Manual GMSUDR15L

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 work piece causes your hand to be in the machine’s “Hazard Zone”, clamp
the work piece in place and move your hand(s) to a safe position before making the cut.
