GENERAL POWER TOOL SAFETY WARNINGS cont.
SERVICE
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 ALL OPERATIONS
Safety Warnings Common for Grinding Operations:
1. This power tool is intended to function as a grinding tool. Read all safety
warnings, instructions, illustrations and specifications provided with this power
tool. Failure to follow all instructions listed below may result in electric shock,
fire and/or serious injury.
2. Operations such as sanding, wire brushing or polishing are not recommended
to be performed with this power tool. Operations for which the power tool was not
designed may create a hazard and cause personal injury.
3. Do not use accessories which are not specifically designed and recommended
by the tool manufacturer. Just because the accessory can be attached to your power
tool, it does not assure safe operation.
4. The rated speed of the accessory must be at least equal to the maximum speed
marked on the power tool. Accessories running faster than their RATED SPEED can
break and fly apart.
5. The outside diameter and the thickness of your accessory must be within the
capacity rating of your power tool. Incorrectly sized accessories cannot be adequately
guarded or controlled.
6. Threaded mounting of accessories must match the GRINDER spindle thread.
For accessories mounted by FLANGES, the arbor hole of the accessory must
fit the locating diameter of the FLANGE. Accessories that do not match the mounting
hardware of the power tool will run out of balance, vibrate excessively and may
cause loss of control.
7. Do not use a damaged accessory. Before each use inspect the accessory such
as abrasive wheels for chips and cracks, backing pad for cracks, tear or excess
wear, wire brush for loose or cracked wires. If power tool or accessory is dropped,
inspect for damage or install an undamaged accessory. After inspecting and
installing an accessory, position yourself and bystanders away from the plane of
the rotating accessory and run the power tool at maximum no-load speed for one
minute. Damaged accessories will normally break apart during this test time.
8. Wear personal protective equipment. Depending on application, use face
shield, safety goggles or safety glasses. As appropriate, wear dust mask, hearing
protectors, gloves and workshop apron capable of stopping small abrasive or
workpiece fragments. The eye protection must be capable of stopping flying debris
generated by various operations. The dust mask or respirator must be capable of filtrating
particles generated by your operation. Prolonged exposure to high intensity noise may
cause hearing loss.
9. 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
accessory may fly away and cause injury beyond immediate area of operation.
10. Hold the power tool by insulated gripping surfaces only, when performing an
operation where the cutting accessory may contact hidden wiring or its own cord.
Cutting accessory contacting a "live" wire may make exposed metal parts of the power
tool "live" and could give the operator an electric shock.

11. Position the cord clear of the spinning accessory. If you lose control, the cord
may be cut or snagged and your hand or arm may be pulled into the spinning accessory.
12. Never lay the power tool down until the accessory has come to a complete stop.
The spinning accessory may grab the surface and pull the power tool out of your control.
13. 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.
14. 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.
15. Do not operate the power tool near flammable materials. Sparks could ignite these
materials.
16. 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, backing pad,
brush or any other accessory. Pinching or snagging causes rapid stalling of the rotating
accessory which in turn causes the uncontrolled power tool to be forced in the direction
opposite of the accessory'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.
1. 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.
2. Never place your hand near the rotating accessory. Accessory may kickback over
your hand.
3. Do not position your body in the area where power tool will move if kickback
occurs. 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 accessory. Corners, sharp edges or bouncing have a tendency to snag
the rotating accessory 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.
