Kickback And Related Warnings; Additional Safety Information - DeWalt XR Li-Ion Flexvolt DCS690 Original Instructions Manual

EngLIsh
workpiece or of a broken wheel may fly away and cause
injury beyond immediate area of operation.
l ) Hold the power tool by insulated gripping surfaces
only, when performing an operation where the
cutting accessory may contact hidden wiring. Cutting
accessory contacting a "live" wire may make exposed
metal parts of the power tool "live" and could give the
operator an electric shock.
m ) Never lay the power tool down until the accessory
has come to a complete stop. The spinning wheel
may grab the surface and pull the power tool out of
your control.
n ) Do not run the power tool while carrying it at your
side. Accidental contact with the spinning accessory
could snag your clothing, pulling the accessory into
your body.
o ) Regularly clean the power tool's air vents. The
motor's fan will draw the dust inside the housing and
excessive accumulation of powdered metal may cause
electrical hazards.
p ) Do not operate the power tool near flammable
materials. Sparks could ignite these materials.
q ) Do not use accessories that require liquid coolants.
Using water or other liquid coolants may result in
electrocution or shock.

Kickback and Related Warnings

Kickback is a sudden reaction to a pinched or snagged rotating
wheel. Pinching or snagging causes rapid stalling of the rotating
wheel which in turn causes the uncontrolled power tool to be
forced in the direction opposite of the wheel's rotation at the point
of the binding.
For example, if an abrasive wheel is snagged or pinched by the
workpiece, the edge of the wheel that is entering into the pinch
point can dig into the surface of the material causing the wheel
to climb out or kick out. The wheel may either jump toward or
away from the operator, depending on direction of the wheel's
movement at the point of pinching. Abrasive wheels may also
break under these conditions.
Kickback is the result of power tool misuse and/or incorrect
operating procedures or conditions and can be avoided by taking
proper precautions as given below.
a ) Maintain a firm grip on the power tool and position
your body and arm to allow you to resist kickback
forces. Always use auxiliary handle, if provided,
for maximum control over kickback or torque
reaction during start-up. The operator can control
torque reactions or kickback forces, if proper precautions
are taken.
b ) Never place your hand near the rotating accessory.
Accessory may kickback over your hand.
c ) Do not position your body in line with the rotating
wheel. Kickback will propel the tool in direction opposite
to the wheel's movement at the point of snagging.
d ) Use special care when working corners, sharp edges
etc. Avoid bouncing and snagging the accessory.
30
Corners, sharp edges or bouncing have a tendency to
snag the rotating accessory and cause loss of control
or kickback.
e ) Do not attach a saw chain, woodcarving blade,
segmented diamond wheel with a peripheral gap
greater than 10 mm or toothed saw blade. Such
blades create frequent kickback and loss of control.
f ) Do not "jam" the wheel or apply excessive pressure.
Do not attempt to make an excessive depth of
cut. Overstressing the wheel increases the loading and
susceptibility to twisting or binding of the wheel in the cut
and the possibility of kickback or wheel breakage.
g ) When wheel is binding or when interrupting a cut
for any reason, switch off the power tool and hold
the power tool motionless until the wheel comes to
a complete stop. Never attempt to remove the wheel
from the cut while the wheel is in motion otherwise
kickback may occur. Investigate and take corrective
action to eliminate the cause of wheel binding.
h ) Do not restart the cutting operation in the
workpiece. Let the wheel reach full speed and
carefully re-enter the cut. The wheel may bind, walk up
or kickback if the power tool is restarted in the workpiece.
i ) Support panels or any oversized workpiece to
minimize the risk of wheel pinching and kickback.
Large workpieces tend to sag under their own
weight. Supports must be placed under the workpiece
near the line of cut and near the edge of the workpiece on
both sides of the wheel.
j ) Use extra caution when making a "pocket cut" into
existing walls or other blind areas. The protruding
wheel may cut gas or water pipes, electrical wiring or
objects that can cause kickback.

Additional Safety Information

Do not use the upper quarter of the wheel for cutting.
•
Serious injury may result due to kickback.
• Use of accessories not specified in this manual is not
recommended and may be hazardous. Use of power
boosters that would cause the tool to be driven at speeds
greater than its rated speed constitutes misuse.
• Do not use circular saw blades with this tool. Serious
injury may result.
• Avoid bouncing the wheel or giving it rough treatment.
If this occurs, stop the tool and inspect the wheel for cracks
or flaws.
Direct sparks away from operator, bystanders or
•
flammable materials. Sparks may be produced while using
a sander or grinder. Sparks may cause burns or start fires.
• Always use front handle. Tighten the handle securely.
The front handle should always be used to maintain control of
the tool at all times.
• Never cut into area that may contain electrical wiring or
piping. Serious injury may result.
