10. Keep bystanders a safe distance away from work
area. Anyone entering the work area must wear
personal protective equipment. Fragments of
workpiece or of a broken wheel may fly away and
cause injury beyond immediate area of operation.
11. Hold power tool by insulated gripping surfaces
only, when performing an operation where the
wheel may contact hidden wiring or its own cord.
Wheel contacting a "live" wire may make exposed
metal parts of the power tool "live" and shock the
operator.
12. Position the cord clear of the spinning wheel. If
you lose control, the cord may be cut or snagged
and your hand or arm may be pulled into the spin-
ning wheel.
13. Never lay the power tool down until the wheel
has come to a complete stop. The spinning wheel
may grab the surface and pull the power tool out of
your control.
14. Do not run the power tool while carrying it at
your side. Accidental contact with the spinning
wheel could snag your clothing, pulling the wheel
into your body.
15. 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.
16. Do not operate the power tool near flammable
materials. Sparks could ignite these materials.
17. Never attempt to cut with the tool held upside
down in a vise. This can lead to serious acci-
dents, because it is extremely dangerous.
18. Some material contains chemicals which may be
toxic. Take caution to prevent dust inhalation
and skin contact. Follow material supplier safety
data.
Kickback and related warnings
Kickback is a sudden reaction to a pinched or snagged
rotating wheel. Pinching or snagging causes rapid stall-
ing of the rotating wheel which in turn causes the uncon-
trolled power tool to be forced in the direction opposite of
the wheel's rotation at the point of the binding.
For example, if a 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 caus-
ing 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. The wheels may also break under these condi-
tions.
Kickback is the result of power tool misuse and/or incor-
rect operating procedures or conditions and can be
avoided by taking proper precautions as given below.
1. Maintain a firm grip on the power tool and posi-
tion 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.
2. Never place your hand near the rotating wheel.
Wheel may kickback over your hand.
3. Do not position your body in line with and
behind the rotating wheel. Kickback will propel the
tool in direction opposite to the wheel's movement at
the point of snagging.

4. Use special care when working corners, sharp
edges etc. Avoid bouncing and snagging the
wheel. Corners, sharp edges or bouncing have a
tendency to snag the rotating wheel and cause loss
of control or kickback.
5. Do not attach a saw chain woodcarving blade or
toothed saw blade. Such blades create frequent
kickback and loss of control.
6. Do not "jam" the wheel or apply excessive pres-
sure. Do not attempt to make an excessive depth
of cut. Overstressing the wheel increases the load-
ing and susceptibility to twisting or binding of the
wheel in the cut and the possibility of kickback or
wheel breakage.
7. 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. Investi-
gate and take corrective action to eliminate the
cause of wheel binding.
8. Do not restart the cutting operation in the work-
piece. Let the wheel reach full speed and care-
fully reenter the cut. The wheel may bind, walk up
or kickback if the power tool is restarted in the work-
piece.
9. Support panels or any oversized workpiece to
minimize the risk of wheel pinching and kick-
back. Large workpieces tend to sag under their own
weight. Supports must be placed under the work-
piece near the line of cut and near the edge of the
workpiece on both sides of the wheel.
10. Use extra caution when making a "pocket cut"
into existing walls or other blind areas. The pro-
truding wheel may cut gas or water pipes, electrical
wiring or objects that can cause kickback.
