Safety Instructions For Mitre Saws - Ryobi RMS254DB Original Instructions Manual

■ Disconnect the plug from the power source and/
or remove the battery pack, if detachable, from
the power tool before making any adjustments,
changing accessories, or storing power tools. Such
preventive safety measures reduce the risk of starting
the power tool accidentally.
■ Store idle power tools out of the reach of children
and do not allow persons unfamiliar with the power
tool or these instructions to operate the power tool.
Power tools are dangerous in the hands of untrained
users.
■ Maintain power tools and accessories. Check for
misalignment or binding of moving parts, breakage
of parts and any other condition that may affect the
power tool's operation. If damaged, have the power
tool repaired before use. Many accidents are caused
by poorly maintained power tools.
■ keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges are
less likely to bind and are easier to control.
■ use the power tool, accessories and tool bits etc.
in accordance with these instructions, taking into
account the working conditions and the work to
be performed. Use of the power tool for operations
different from those intended could result in a
hazardous situation.
■ keep handles and grasping surfaces dry, clean
and free from oil and grease. Slippery handles and
grasping surfaces do not allow for safe handling and
control of the tool in unexpected situations.
SeRvICe
■ Have your power tool serviced by a qualified repair
person using only identical replacement parts.
This will ensure that the safety of the power tool is
maintained.

Safety InStRuCtIonS foR MItRe SawS

■ Mitre 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
possible. 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
2
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
cutting 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 contact 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 mitre saw is mounted or placed on a
level, firm work surface before use. A level and
firm work surface reduces the risk of the mitre saw
becoming unstable.
■ plan your work. every time you change the bevel or
mitre 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 mitre 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
