Power Tool Use And Care; Service; Safety Instructions For Mitre Saws - DeWalt DWS780 Manual

d ) Remove any adjusting key or wrench before turning the power
tool on. A wrench or a key left attached to a rotating part of the
power tool may result in personal injury.
e ) Do not overreach. Keep proper footing and balance at all times.
This enables better control of the power tool in unexpected situations.
f ) Dress properly. Do not wear loose clothing or jewellery. Keep
your hair and clothing away from moving parts. Loose clothes,
jewellery or long hair can be caught in moving parts.
g ) If devices are provided for the connection of dust extraction and
collection facilities, ensure these are connected and properly
used. Use of dust collection can reduce dust-related hazards.
h ) Do not let familiarity gained from frequent use of tools allow
you to become complacent and ignore tool safety principles. A
careless action can cause severe injury within a fraction of a second.

Power Tool Use and Care

a ) Do not force the power tool. Use the correct power tool for your
application. The correct power tool will do the job better and safer at
the rate for which it was designed.
b ) Do not use the power tool if the switch does not turn it on and
off. Any power tool that cannot be controlled with the switch is
dangerous and must be repaired.
c ) 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.
d ) 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.
e ) 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.
f ) Keep cutting tools sharp and clean. Properly maintained cutting
tools with sharp cutting edges are less likely to bind and are easier
to control.
g ) 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.
h ) 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

a ) 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

a ) 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.
b ) 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.
c ) 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.
d ) 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.
e ) 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.
f ) 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.
g ) 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.
h ) 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.
i ) 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.
j ) 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.
k ) 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.
l ) 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.
m ) 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.
n ) 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.
o ) 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.
p ) Let the blade reach full speed before contacting the workpiece.
This will reduce the risk of the workpiece being thrown.
