which cannot be built into this product, but must be supplied by the operator.
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.

Vibration Safety
This tool vibrates during use. Repeated or long-term exposure to vibration may
cause temporary or permanent physical injury, particularly to the hands, arms
and shoulders. To reduce the risk of vibration-related injury:
1. Anyone using vibrating tools regularly or for an extended period should
first be examined by a doctor and then have regular medical check-ups to
ensure medical problems are not being caused or worsened from use. Pregnant
women or people who have impaired blood circulation to the hand, past hand
injuries, nervous system disorders, diabetes, or Raynaud’s Disease should not
use this tool. If you feel any medical or physical symptoms related to
vibration (such as tingling, numbness, and white or blue fingers), seek
medical advice as soon as possible.
2. Do not smoke during use. Nicotine reduces the blood supply to the hands
and fingers, increasing the risk of vibration-related injury.
3. Wear suitable gloves to reduce the vibration effects on the user.
4. Use tools with the lowest vibration when there is a choice between
different processes.
5. Include vibration-free periods each day of work.
6. Grip tool as lightly as possible (while still keeping safe control of it).
Let the tool do the work.
7. To reduce vibration, maintain the tool as explained in this manual. If any
abnormal vibration occurs, stop use immediately.

Grounding
TO PREVENT ELECTRIC SHOCK AND DEATH FROM INCORRECT GROUNDING WIRE CONNECTION:
Check with a qualified electrician if you are in doubt as to whether the
outlet is properly grounded. Do not modify the power cord plug provided with
the tool. Never remove the grounding prong from the plug. Do not use the tool
if the power cord or plug is damaged. If damaged, have it repaired by a
service facility before use. If the plug will not fit the outlet, have a
proper outlet installed by a qualified electrician.
Grounded Tools: Tools with Three Prong Plugs
3-Prong Plug and Outlet
1. Tools marked with “Grounding Required” have a three wire cord and three
prong grounding plug. The plug must be connected to a properly grounded
outlet. If the tool should electrically malfunction or break down, grounding
provides a low resistance path to carry electricity away from the user,
reducing the risk of electric shock. (See 3-Prong Plug and Outlet.)
2. The grounding prong in the plug is connected through the green wire inside
the cord to the grounding system in the tool. The green wire in the cord must
be the only wire connected to the tool’s grounding system and must never be
attached to an electrically “live” terminal. (See 3-Prong Plug and Outlet.)
3. The tool must be plugged into an appropriate outlet, properly installed
and grounded in accordance with all codes and ordinances. The plug and outlet
should look like those in the preceding illustration. (See 3-Prong Plug and
Outlet.)
Double Insulated Tools: Tools with Two Prong Plugs
Outlets for 2-Prong Plug
1. Tools marked “Double Insulated” do not require grounding. They have a
special double insulation system which satisfies OSHA requirements and
complies with the applicable standards of Underwriters Laboratories, Inc., the
Canadian Standard Association, and the National Electrical Code.
2. Double insulated tools may be used in either of the 120 volt outlets shown
in the preceding illustration. (See Outlets for 2-Prong Plug.)

SAFETY
SETUP
Extension Cords
1. Grounded tools require a three wire extension cord. Double Insulated tools
can use either a two or three wire extension cord.
2. As the distance from the supply outlet increases, you must use a heavier
gauge extension cord. Using extension cords with inadequately sized wire
causes a serious drop in voltage, resulting in loss of power and possible tool
damage. (See Table A.)
3. The smaller the gauge number of the wire, the greater the capacity of the
cord. For example, a 14 gauge cord can carry a higher current than a 16 gauge
cord. (See Table A.)
4. When using more than one extension cord to make up the total length, make
sure each cord contains at least the minimum wire size required. (See Table
A.)
5. If you are using one extension cord for more than one tool, add the
nameplate amperes and use the sum to determine the required minimum cord size.
(See Table A.)
6. If you are using an extension cord outdoors, make sure it is marked with
the suffix “W-A” (“W” in Canada) to indicate it is acceptable for outdoor use.
7. Make sure the extension cord is properly wired and in good electrical condition. Always replace a damaged extension cord or have it repaired by a qualified electrician before using it.
8. Protect the extension cords from sharp objects, excessive heat, and damp or wet areas.
