8. Do not use damaged wheels. Before each use,
inspect the wheels for chips and cracks. If the
power tool or wheel is dropped, inspect for
damage or install an undamaged wheel. After
inspecting and installing the wheel, position
yourself and bystanders away from the plane
of the rotating wheel and run the power tool
at maximum no load speed for one minute.

this test time.
9. Wear personal protective equipment.
Depending on application, use face shield,
safety goggles or safety glasses. As appro-
priate, wear dust mask, hearing protectors,
gloves and shop apron capable of stopping
small abrasive or workpiece fragments. The

10. Keep bystanders a safe distance away from
work area. Anyone entering the work area
must wear personal protective equipment.

11. Regularly clean the power tool’s air vents. The
motor’s fan can draw the dust inside the housing
and excessive accumulation of powdered metal
may cause electrical hazards.
12. Do not operate the power tool near ammable
materials. Do not operate the power tool while
placed on a combustible surface such as
wood. Sparks could ignite these materials.
13. Do not use accessories that require liquid
coolants.Usingwaterorotherliquidcoolants
may result in electrocution or shock.

1. Maintain a rm grip on the power tool and
position your body and arm to allow you to
resist kickback forces. The operator can control

taken.
2. Do not position your body in line with the
rotating wheel.Ifkickbackoccurs,itwillpropel
the cutting unit upwards toward the operator.
3. Do not attach a saw chain, woodcarving blade,
segmented diamond wheel with a peripheral
gap greater than 10 mm or toothed saw blade.

4. Do not “jam” the wheel or apply excessive
pressure. Do not attempt to make an excessive
depth of cut. Overstressing the wheel increases

backorwheelbreakage.
5. When the wheel is binding or when interrupt-
ing a cut for any reason, switch off the power
tool and hold the cutting unit 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
eliminatethecauseofwheelbinding.
6. Do not restart the cutting operation in the
workpiece. Let the wheel reach full speed and
carefully re-enter the cut.Thewheelmaybind,

7. Support any oversized workpiece to minimize
the risk of wheel pinching and kickback. Large
workpieces tend to sag under their own weight.

Additional safety warnings
1. Watch out for ying sparks when operating.
Theycancauseinjuryorignitecombustible
materials.
2. Secure work. Use clamps or a vise to hold
work when practical. It's safer than using your
handanditfreesbothhandstooperatetool.
3. Secure the cut-off wheel carefully.
4. Be careful not to damage the spindle, anges
(especially the installing surface) or bolt, or
the cut-off wheel itself might break.
5. Keep guards in place and in working order.
6. Hold the handle rmly.
7. Keep hands away from rotating parts.
8. Make sure the cut-off wheel is not contacting
the work-piece before the switch is turned on.
9. Before each use, watch for utter or excessive
vibration that might be caused by poor instal-
lation or a poorly balanced wheel.
10. Remove material or debris from the area
that might be ignited by sparks. Be sure that
others are not in the path of the sparks. Keep
a proper, charged re extinguisher closely
available.
11. If the cut-off wheel stops during the opera-
tion, makes an odd noise or begins to vibrate,
switch off the tool immediately.
12. Always switch off and wait for the cut-off
wheel to come to a complete stop before
removing, securing workpiece, working vise,
changing work position, angle or the cut-off
wheel itself.
