• Do not expose a battery pack or tool to fire or exces-
sive temperature. Exposure to fire or temperature
above 265°F (130°C) may cause explosion.
• Follow all charging instructions and do not charge
the battery pack or tool outside the temperature
range specified in the instructions. Charging im-
properly or at temperatures outside the specified range
may damage the battery and increase the risk of fire.
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.
• Never service damaged battery packs. Service
of battery packs should only be performed by the
manufacturer or authorized service providers.
SPECIFIC SAFETY RULES FOR
MITER SAWS
• 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
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 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 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 sur-
face reduces the risk of the miter 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 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 mitre saw off. Wait for all moving parts to stop
and disconnect the plug from the power source
and/or remove 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 cause the saw head to
be suddenly pulled downward, causing a risk of injury.
To reduce the risk of injury in ap-
WARNING
plications that produce a consider-
able amount of dust, use an OSHA compliant
dust extraction solution in accordance with the
solution's operating instructions.
• Always use common sense and be cautious when
using tools. It is not possible to anticipate every
situation that could result in a dangerous outcome.
Do not use this tool if you do not understand these
operating instructions or you feel the work is beyond
your capability; contact Milwaukee Tool or a trained
professional for additional information or training.
• Maintain labels and nameplates. These carry
important information. If unreadable or missing, contact
a MILWAUKEE service facility for a free replacement.
