General Safety Instructions

A ARNING! Read and understand all instructions. Failure to follow all instructions listed

below may result in electric shock, fire and/or serious personal injui_.

SLAVE THESE INSTRUCTIONS

WORK AREA

* Keep your work area clean and well fit. Cluttered benches and dark areas invite accidents.

* Do not operate power tools in explosive atmospheres, such as in the presence of flam-

mable liquids, gases, or dust. Power tools create sparks which may ignite the dust or

fumes.

* Keep bystanders, children, and visitors away while operating apower tool Distractions

can cause you to lose control.

ELECTRICAL SAFETY

* Grounded tools must be plugged into an outlet properly installed and grounded in

accordance with all codes and ordinances. Never remove the grounding prong or

modify the plug in any way. Do not use any adaptor plugs. Check with a qualified elec-

trician if you are in doubt as to whether the outlet is properly grounded, ff the tools

should electrically malfunction or break down, grounding provides a low resistance path to

carry electricity away from the user. Applicable only to Class I (grounded) tools.

* Double insulated tools are equipped with a polarized plug (one blade is wider than the

other.) This plug will fit in a polarized outlet only one way. If the plug does not fit fully

in the outlet, reverse the plug. If it still does not fit, contact a qualified electrician to

install a polarized outlet. Do not change the plug in any way. Double insulation [] elim-

inates the need for the three wire grounded power cord and grounded power supply system.

Applicable only to Class II (double insulated) tools.

* Avoid body contact with grounded surfaces such as pipes, radiators, ranges and

refrigerators. There is an increased risk of electric shock if your body is grounded.

* Don't expose power tools to rain or wet conditions. Water entering a power tool will

increase the risk of electric shock.

* Do not abuse the cord. Never use the cord to carry the tools or pull the plug from an

outlet. Keep cord away from heat, oil, sharp edges or moving parts. Replace damaged

cords immediately. Damaged cords increase the risk of electric shock.

* When operating a power tool outside, use an outdoor extension cord marked "W-A"

or "W." These cords are rated for outdoor use and reduce the risk of electric shock. When

using an extension cord, be sure to use one heavy enough to carry the current your product

will draw. An undersized cord will cause a drop in line voltage resulting in loss of power and

overheating. The following table shows the correct size to use depending on cord length and

nameplate ampere rating. If in doubt, use the next heavier gage. The smaller the gage num-

ber, the heavier the cord.

PERSONAL SAFETY

* Stay alert, watch what you are doing and use common sense when operating a power

tool Do not use tool while tired or under the influence of drugs, alcohol, or medication.

A moment of inattention while operating power tools may result in serious personal injui_.

* Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep your hair,

clothing, and gloves away from moving parts. Loose clothing, jewelry, or long hair can be

caught in moving parts. Air vents often cover moving parts and should also be avoided.

* Avoid accidental starting. Be sure switch is off before plugging in. Carrying tools with

your finger on the switch or plugging in tools that have the switch on invites accidents.

* Remove adjusting keys or wrenches before turning the tool on. A wrench or a key that

is left attached to a rotating part of the tool may result in personal injury.

* Do not overreach. Keep proper footing and balance at all times. Proper footing and bal-

ance enables better control of the tool in unexpected situations.

* Use safety equipment. Always wear eye protection. Dust mask, non-skid safety shoes,

hard hat, or hearing protection must be used for appropriate conditions.

TOOL USE AND CARE

* Use clamps or other practical way to secure and support the workpiece to a stable

platform. Holding the work by hand or against your body is unstable and may lead to loss of

control.

* Do not force tool Use the correct tool for your application. The correct tool will do the

job better and safer at the rate for which it is designed.

* Do not use tool if switch does not turn it on or off. Any tool that cannot be controlled with

the switch is dangerous and must be repaired.

* Disconnect the plug from the power source before making any adjustments, changing

accessories, or storing the tool Such preventative safety measures reduce the risk of

starting the tool accidentally.

* Store idle tools out of reach of children and other untrained persons. Tools are dan-

gerous in the hands of untrained users.

. Maintain tools with care. Keep cutting tools sharp and clean. Properly maintained tools,

with sharp cutting edges are less likely to bind and are easier to control.

* Check for misalignment or binding of moving parts, breakage of parts, and any other

condition that may affect the tool's operation. If damaged, have the tool serviced

before using. Many accidents are caused by poorly maintained tools.

* Use only accessories that are recommended by the manufacturer for your model

Accessories that may be suitable for one tool, may become hazardous when used on

another tool.

SERVICE

* Tool service must be performed only by qualified repair personnel Service or mainte-

nance performed by unqualified personnel could result in a risk of injury

* When servicing a tool, use only identical replacement parts. Follow instructions in the

Maintenance section of this manual Use of unauthorized parts or failure to follow mainte-

nance instructions may create a risk of electric shock or injury.

Additional Safety Instructions for Sanders

. Accessories must be rated for at least the speed recommended on the tool warning

label Wheels and other accessories running over rated speed can fly apart and cause inju_

Accessory ratings must be above listed minimum wheel speed as shown on tool nameplate.

, Hold tool by insulated gripping surfaces when performing an operation where the cut-

ting tool may contact hidden wiring or its own cord. Contact with a 'five" wire will make

exposed metal parts of the tool 'five" and shock the operator.

, Always wear eye protection and a respirator when sanding.

, Sanding of lead-based paint is not recommended. See Precautions To Take When

Sanding Paint for additional information before sanding paint.

, Do not operate the unit without the dust collection bag.

, Clean your tool out periodically.

, Empty dust bag frequently, especially when sanding resin coated surfaces such as

polyurethane, varnish, shellac, etc. Dispose of coated dust particles according to the finish

manufacturer's guidelines, or place in a metal can with a tight-fitting metal lid. Remove coated

dust particles from the premises daily. The accumulation of fine sanding dust particles may

serf ignite and cause fire.

, Replace worn CFS disc when it causes high tool rpm. High tool rpm caused by a worn

out CFS disc may result in separation of sanding pad from the sander, possibly causing per-

sonal injui_. For instructions on replacing the CFS disc, see Tool Care.

_ WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other con-

struction activities contains chemicals known to cause cancer, birth defects or other reproduc-

tive harm. Some examples of these chemicals are:

* lead from lead-based paints,

* crystalline silica from bricks and cement and other masonry products, and

* arsenic and chromium from chemically-treated lumber (CCA).

Your risk from these exposures varies, depending on how often you do this type of work. To

reduce your exposure to these chemicals: work in a weft ventilated area, and work with

approved safety equipment, such as those dust masks that are specially designed to filter out

microscopic particles.

* Avoid prolonged contact with dust from power sanding, sawing, grinding, drilling, and

other construction activities. Wear protective clothing and wash exposed areas with

soap and water. Allowing dust to get into your mouth, eyes, or lay on the skin may promote

absorption of harmful chemicals.

_, WARNING: Use of this tool can generate and/or disburse dust, which may cause serious and

permanent respiratory or other injury. Always use NIOSH/OSHA approved respiratory protection

appropriate for the dust exposure. Direct particles away from face and body.

J_,CAUTION: Wear appropriate hearing protection during use. Under some conditions and

duration of use, noise from this product may contribute to hearing loss.
