RIDGID R4221 Operator's Manual page 4

SPECIFIC SAFETY RULES
 NEVER reach to pick up a workpiece, a piece of scrap,
or anything else that is in or near the cutting path of the
blade.
 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.
 AVOID AWKWARD OPERATIONS AND HAND
POSITIONS where a sudden slip could cause your hand
to move into the blade. ALWAYS make sure you have
good balance. NEVER operate your miter saw on the
floor or in a crouched position.
 ALWAYS release the power switch and allow the saw blade
to stop rotating before raising it out of the workpiece.
 DO NOT TURN THE MOTOR SWITCH ON AND OFF
RAPIDLY. This could cause the saw blade to loosen and
could create a hazard. Should this ever occur, stand clear
and allow the saw blade to come to a complete stop.
Disconnect your saw from the power supply and securely
retighten the blade bolt.
 IF ANY PART OF THIS MITER SAW IS MISSING or
should break, bend, or fail in any way, or should any
electrical component fail to perform properly, shut off
the power switch, remove the miter saw plug from the
power source and have damaged, missing, or failed parts
replaced before resuming operation.
 IF THE POWER SUPPLY CORD IS DAMAGED, it must
be replaced only by the manufacturer or by an authorized
service center to avoid risk.
 ALWAYS STAY ALERT! Do not allow familiarity (gained
from frequent use of your saw) to cause a careless
mistake. ALWAYS REMEMBER that a careless fraction
of a second is sufficient to inflict severe injury.
