Inspect your workpiece before cutting. If the work-
u
piece 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 work-
pieces 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,
u
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
u
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,
u
firm work surface before use. A level and firm work sur-
face reduces the risk of the mitre saw becoming unstable.
Plan your work. Every time you change the bevel or
u
mitre angle setting, make sure the adjustable fence is
set correctly to support the workpiece and will not in-
terfere 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,
u
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
u
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
u
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
u
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
u
workpiece. This will reduce the risk of the workpiece be-
ing thrown.
If the workpiece or blade becomes jammed, turn the
u
mitre 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 mitre saw.
After finishing the cut, release the switch, hold the
u
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
u
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.
Do not let go of the handle once the saw head has
u
reached the lowest position. Always guide the saw
head back to the top position by hand. There is a risk of
injury if the saw head moves in an uncontrolled manner.
Keep your work area clean. Material mixtures are partic-
u
ularly hazardous. Light metal dust may catch fire or ex-
plode.
Do not use dull, cracked, bent or damaged saw blades.
u
Unsharpened or improperly set saw blades produce
narrow kerf causing excessive friction, blade binding
and kickback.
Do not use saw blades made from high speed steel
u
(HSS). Such saw blades can easily break.
Always use saw blades with correct size and shape
u
(diamond versus round) of arbour holes. Saw blades
that do not match the mounting hardware of the saw will
run off-centre, causing loss of control.
Never remove cuttings, wood chips, etc. from the cut-
u
ting area while the power tool is running. Always guide
the tool arm back to the neutral position first and then
switch the power tool off.
Do not touch the saw blade after working before it has
u
cooled. The saw blade becomes very hot while working.
In case of damage and improper use of the battery, va-
u
pours may be emitted. The battery can set alight or ex-
plode. Ensure the area is well ventilated and seek medical
attention should you experience any adverse effects. The
vapours may irritate the respiratory system.
Do not open the battery. There is a risk of short-circuit-
u
ing.
The battery can be damaged by pointed objects such
u
as nails or screwdrivers or by force applied externally.
An internal short circuit may occur, causing the battery to
burn, smoke, explode or overheat.
Only use the battery with products from the manufac-
u
turer. This is the only way in which you can protect the
battery against dangerous overload.
Protect the battery against heat, e.g. against
continuous intense sunlight, fire, dirt, water
and moisture. There is a risk of explosion and
short-circuiting.
The power tool is delivered with a laser warning sign
u
(see table: "Symbols and their meaning").
If the text of the laser warning label is not in your na-
u
tional language, stick the provided warning label in
your national language over it before operating for the
first time.
