Power Tool Use And Care; Safety Rules For Mitre Saws - DeWalt DWS773 Instructions Manual

4) 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 the
battery pack 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. 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.
5) 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 Rules for Mitre Saws

a ) Mitre saws are intended to cut wood or wood-like products,
they cannot be usedwith 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
fromabrasive cutting will burn the lower guard, the kerf insert and
other plastic parts.
b ) Use clamps to support the workpiece whenever possible. If
supporting theworkpiece by hand, you must always keep
your hand at least 100 mm from eitherside of the saw blade.
Do not use this saw to cut pieces that are too small to besecurely
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
24
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.
q ) If the workpiece or blade becomes jammed, turn the mitre
saw off. Wait for all moving parts to stop and disconnect the
