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
This product has been designed only for the purposes
listed below:
 Cross cutting wood and plastic.
 Cross cutting miters, joints, etc. for picture frames,
moldings, door casings, and fine joinery.
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
your miter saw to a workbench. Never operate your
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, 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.
WARNING:
Do not start your 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. Failure to heed this warning can also result in
serious personal injury.
CUTTING WITh YOUR COMPOUND MITER
SAW
WARNING:
When using a work clamp or C-clamp to secure
your 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 pos-
sible serious personal injury.
WARNING:
To avoid serious personal injury, always tighten the
miter lock handle securely before making a cut.
Failure to do so could result in movement of the
control arm or miter table while making a cut.
MITER ThUMBWhEEL
The miter thumbwheel, when used with the miter lock lever
lifted (unlocked), can release the miter table from pre-set
index points.
To align with miter scale:
 Lift the miter lock lever to unlock.
 Rotate and hold thumbwheel so that the yellow dot on
the thumbwheel aligns with indicator point (white dot) on
the miter lock lever to override index points.
 When close to desired angle, release the thumbwheel.
NOTE: When the orange dot on the thumbwheel clicks
into place (aligned with the indicator point), the miter table
is locked into a preset index point.
 Push the miter lock lever down to lock the miter table.
To bypass preset index points:
 Lift the miter lock lever to unlock.
 Rotate the thumbwheel so that the white dot on the
thumbwheel aligns with the indicator point (white dot) on
the miter lock lever.
