Miter Saw Specific Safety Rules - Ryobi PBLMS01 Operator's Manual

MITER SAW SPECIFIC SAFETY RULES

 Miter saws are intended to cut wood or wood-like
products, they cannot be used with abrasive cut-off
wheels for cutting ferrous material such as bars, rods,
studs, etc. Abrasive dust causes moving parts such as
the lower guard to jam. Sparks from abrasive cutting will
burn the lower guard, the kerf insert and other plastic
parts.
 Use clamps to support the workpiece whenever pos-
sible. If supporting the workpiece by hand, you must
always keep your hand at least 100 mm from either
side of the saw blade. Do not use this saw to cut pieces
that are too small to be securely clamped or held by
hand. If your hand is placed too close to the saw blade,
there is an increased risk of injury from blade contact.
 The workpiece must be stationary and clamped or
held against both the fence and the table. Do not feed
the workpiece into the blade or cut "freehand" in any
way. Unrestrained or moving workpieces could be thrown
at high speeds, causing injury.
 Push the saw through the workpiece. Do not pull the
saw through the workpiece. To make a cut, raise the
saw head and pull it out over the workpiece without
cutting, start the motor, press the saw head down
and push the saw through the workpiece. Cutting on
the pull stroke is likely to cause the saw blade to climb
on top of the workpiece and violently throw the blade
assembly towards the operator.
 Never cross your hand over the intended line of cut-
ting either in front or behind the saw blade. Supporting
the workpiece "cross handed" i.e. holding the workpiece
to the right of the saw blade with your left hand or vice
versa is very dangerous.
 Do not reach behind the fence with either hand closer
than 100 mm from either side of the saw blade, to
remove wood scraps, or for any other reason while
the blade is spinning. The proximity of the spinning saw
blade to your hand may not be obvious and you may be
seriously injured.
 Inspect your workpiece before cutting. If the workpiece
is bowed or warped, clamp it with the outside bowed
face toward the fence. Always make certain that there
is no gap between the workpiece, fence and table
along the line of the cut. Bent or warped workpieces can
twist or shift and may cause binding on the spinning saw
blade while cutting. There should be no nails or foreign
objects in the workpiece.
 Do not use the saw until the table is clear of all tools,
wood scraps, etc., except for the workpiece. Small
debris or loose pieces of wood or other objects that con-
tact the revolving blade can be thrown with high speed.
 Cut only one workpiece at a time. Stacked multiple
workpieces cannot be adequately clamped or braced
and may bind on the blade or shift during cutting.
 Ensure the miter saw is mounted or placed on a level,
firm work surface before use. A level and firm work
surface reduces the risk of the miter saw becoming un-
stable.
 Plan your work. Every time you change the bevel or
miter angle setting, make sure the adjustable fence
is set correctly to support the workpiece and will not
interfere with the blade or the guarding system. Without
turning the tool "ON" and with no workpiece on the table,
move the saw blade through a complete simulated cut to
assure there will be no interference or danger of cutting
the fence.
 Provide adequate support such as table extensions,
saw horses, etc. for a workpiece that is wider or longer
than the table top. Workpieces longer or wider than the
miter saw table can tip if not securely supported. If the
cut-off piece or workpiece tips, it can lift the lower guard
or be thrown by the spinning blade.
 Do not use another person as a substitute for a table
extension or as additional support. Unstable support
for the workpiece can cause the blade to bind or the
workpiece to shift during the cutting operation pulling
you and the helper into the spinning blade.
 The cut-off piece must not be jammed or pressed by
any means against the spinning saw blade. If confined,
i.e. using length stops, the cut-off piece could get wedged
against the blade and thrown violently.
 Always use a clamp or a fixture designed to properly
support round material such as rods or tubing. Rods
have a tendency to roll while being cut, causing the blade
to bite and pull the work with your hand into the blade.
 Let the blade reach full speed before contacting the
workpiece. This will reduce the risk of the workpiece
being thrown.
 If the workpiece or blade becomes jammed, turn the
miter saw off. Wait for all moving parts to stop and
disconnect the plug from the power source and/or re-
move the battery pack. Then work to free the jammed
material. Continued sawing with a jammed workpiece
could cause loss of control or damage to the miter saw.
 After finishing the cut, release the switch, hold the
saw head down and wait for the blade to stop before
removing the cut-off piece. Reaching with your hand
near the coasting blade is dangerous.
 Hold the handle firmly when making an incomplete cut
or when releasing the switch before the saw head is
completely in the down position. The braking action of
the saw may to be suddenly pulled downward, causing
a risk of injury.
 Save these instructions. Refer to them frequently and
use to instruct other users. If you loan someone this tool,
loan them these instructions also.
