General Safety Rules for All Battery Operated Tools

WARNING

Read and understand all instructions. Failure to follow all instructions listed below, may result in electric shock, fire and/or serious personal injury.

SAVE THESE INSTRUCTIONS

Work Area

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

Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust. Power tools create sparks which may ignite the dust or fumes.

Keep bystanders, children, and visitors away while operating a power tool. Distractions can cause you to lose control.

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 injury.

Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep your hair, clothing, and gloves away from moving parts. Loose clothes, jewelry, or long hair can be caught in moving parts.

Avoid accidental starting. Be sure switch is in the locked or off position before inserting battery pack. Carrying tools with your finger on the switch or inserting the battery pack into a tool with 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 balance enable better control of the tool in unexpected situations.

Use safety equipment. Always wear eye protection. Dust mask must be used for appropriate conditions.

Tool Use and Care

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. A tool that cannot be controlled with the switch is dangerous and must be repaired.

Disconnect battery pack from tool or place the switch in the locked or off position before making any adjustments, changing accessories, or storing the tool. Such preventive safety measures reduce the risk of starting the tool accidentally.

Store idle tools out of reach of children and other untrained persons. Tools are dangerous in the hands of untrained users.

When battery pack is not in use, keep it away from other metal objects like: paper clips, coins, keys,

nails, screws, or other small metal objects that can make a connection from one terminal to another. Shorting the battery terminals together may cause sparks, burns, or a fire.

Maintain tools with care. Keep cutting tools sharp and clean. Properly maintained tools with sharp cutting edge 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 create a risk of injury when used on another tool.

Service

Tool service must be performed only by qualified repair personnel. Service or maintenance performed by unqualified personnel may 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 Maintenance Instructions may create a risk of shock or injury.

Safety Rules for Cordless Rotary Tools

Accessories must be rated for at least the speed recommended on the tool warning label. Other accessories running over rated speed can fly apart and cause injury.

Hold tool by insulated gripping surfaces when performing an operation where the cutting tool may contact hidden wiring. Contact with a "live" wire will make exposed metal parts of the tool "live" and shock the operator. If cutting into existing walls or other

blind areas where electrical wiring may exist is unavoidable, disconnect all fuses or circuit breakers feeding this worksite.

Before changing accessories remove battery pack. Accidental starting may occur because battery tools with a battery inserted are in the operative condition.

Be aware of the switch location, when placing the tool down or when picking the tool up. You may accidentally activate the switch.

Always hold the tool with two hands during startup. The reaction torque of the motor can cause the tool to twist.

Always wear safety goggles and dust mask. Use only in well ventilated area. Using personal safety devices and working in safe environment reduces risk of injury.

After changing the accessories or making any adjustments, make sure the collet nut and any other adjustment devices are securely tightened.

Loose adjustment device can unexpectedly shift, causing loss of control, loose rotating components will be violently thrown.

Do not reach in the area of the spinning accessory. The proximity of the spinning accessory to your hand may not always be obvious.

Never start the tool when the accessory is engaged in the material. The accessory may grab the material causing loss of control of the accessory.

Do not leave a running tool unattended, turn power off. Only when tool comes to a complete stop it is safe to put it down.

Do not sand near flammable materials. Sparks from the acessory could ignite these materials.

Do not touch the bit or collet after use. After use the bit and collet are too hot to be touched by bare hands.

Regularly clean the tool's air vents by compressed air. Excessive accumulation of powdered nail inside the motor housing may cause electrical failures.

Do not allow familiarity gained from frequent use of your tool to become commonplace. Always remember that a careless fraction of a second is sufficient to inflict severe injury.

Do not alter or misuse tool. Any alteration or modification is a misuse and may result in serious personal injury.

This product is not intended for use as a dental drill, in human or veterinary medical applications. Serious injury may result.

WARNING Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to cause cancer, birth defects or other reproductive 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.

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 well ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to filter out microscopic particles.

Why Use a Dremel Rotary Tool to Groom Pet Nails?

Of the reasons why people prefer to groom their pet's nails with a Dremel rotary tool, the main reason they do is for the pet's overall comfort. Scissors and guillotine-type clippers apply pressure and pinch the toenail, which can be very uncomfortable to pet toes and feet. Also, clipping toenails increases the likelihood of cutting the internal blood supply to the nail, called the quick. Because grinding is more gradual than clipping, it is easier to stop in time before reaching the quick. Should you nick the quick using a rotary tool, the cut is usually smaller, and will heal more quickly than a cut made with a nail clipper.

Before you start

Grooming a pet's nails for the first time can be a worrisome experience for both the pet and the pet owner. Nail grooming does not have to be a stressful experience. By starting early and considering grooming to be part of your pets training, your pet will become used having their nails groomed.

It is recommended that your pet should feel comfortable with you touching and handling their feet before you expose them to the rotary tool. One way to do this is to take time to manipulate their paws for a few minutes at least once daily. Giving your pet a snack that they enjoy is a good way to associate having their feet touched with a positive food-related experience.

The next step is to get the pet gradually accustomed to the rotary tool itself. Let the pet sniff the tool while it is turned off. Next while keeping the tool in your hand, turn the tool on and let him get used to the sound it makes. Try to get him to sit or lay on his side while the tool is in your hand and running.

Eventually, you need to work up to being able to touch the rotating sanding drum to the pet's toe

nails. Do no grinding at this time; simply let the animal become familiar with this new situation. You do not need to touch the tool to the nail for more than a second.

Throughout the entire acclimation process, continue to praise the pet and reward good behavior with his favorite snack. This process may take a couple of days or even weeks. Before long, both you and your pet will be able to relax and even enjoy this grooming time that you share together.

Nail Anatomy

Before trimming pet nails you will need to be able to identify the quick. The diagram shows the basic anatomy of a dog's toenail. The outer nail is hard, and has no feeling because it has no nerve endings. The core of the nail is the quick. It is made up of tiny blood vessels, nerve endings and is very sensitive. The quick is a vein that "feeds" the toenail. Should you cut the quick while trimming a nail, the nail will start to bleed.

Light colored nails are often transparent enough to allow you to see the quick's pink core. Dark colored nails may not allow you to see where the quick is. Sometimes, dog's have both light and dark colored nails that allow you to estimate the length of the quick.

The diagram also shows the ideal angle in which to trim a pet's nails. The proper angle may vary according to the pet owner's wishes or the pet's unique anatomy.

The Nail Grooming Process

It is important to let the speed of the rotary tool do the work. You should never apply pressure to the toenail with the spinning sanding drum. Allow the speed of the sanding drum to remove the nail material without adding pressure. Pressure causes the nail to get too hot causing discomfort for your pet.

The rotary tool's spinning sanding drum should not be kept against the nail longer than three seconds at a time. It is recommended that you alternate between all the nails on two paws at a time. This rotation method allows the nails to cool before they are ground a second time.

Support the toe and nail in one hand while using the rotary tool in the other hand. This lessens the vibration of the grinding procedure and is more comfortable for your pet. Pushing gently on the bottom of the paw's pad extends the nail slightly for easier grooming.

Pet Safety

Secure the pet. Some pets may become nervous in the presence of the tool. The operator needs both hands to groom the nail. It may be helpful to have another person assist in restraining the pet.

Keep pet hair away from spinning parts. Hair can entangle in the tool, causing injury to your pet.

Safety Tips

Should hair be accidentally caught in the rotary tool, immediately turn off the tool and untangle the hair from the tool.

For pets with particularly long hair, use an old sock to cover the toe, foot and leg of the pet and isolate the nail. Push the nail out through a small opening at the tip of the sock to groom the nail.

Keep styptic powder on hand in case of bleeding. Styptic powder is available at most pet supply stores. Follow the directions on the packaging for proper use instructions.

Using the Cordless Rotary Tool

The first step in learning to use the Cordless Rotary Tool is to get the "feel" of it. Hold it in your hand and feel its weight and balance. Feel the taper of the housing. This taper permits the tool to be grasped much like a pen or pencil.

When you turn on the tool for the first time, hold it away from your face. Accessories can be damaged during handling, and can fly apart as they come up to speed. This is not common, but it does happen.

Practice on scrap materials first to see how the Cordless Rotary Tool works. Keep in mind that the work is done by the speed of the tool and by the accessory in the collet. You should not lean on or push the tool into the work.

Instead, lower the spinning accessory lightly to the work and allow it to touch the point at which you want to begin. Concentrate on guiding the tool over the work using very little pressure from your hand. Allow the accessory to do the work.

Usually, it is best to make a series of passes with the tool rather than attempt to do all the work in one pass. Pass the tool back and forth over the work, much as you would a small paint brush. For most work, the deft, gentle touch is best. With it, you have the best control, are less likely to make errors, and will get the most efficient work out of the accessory.

For best control in close work, grip the Rotary Tool like a pencil between your thumb and forefinger.

The "handgrip" method of holding the tool is used for operations such as sanding a flat surface.

Set the speed indicator to fit the job to achieve the best job results when working with different materials.

To select the right speed for each job, use a practice piece of material. Vary speed to find the best speed for the accessory you are using and the job to be done.

On the Model 761, there is a LO and HI switch. When the switch indicator is in position 1 or LO, the tool runs at about 7,000 RPM. When the switch indicator is in position 2 or HI, the tool runs at about 14,000 RPM.

NOTE: Speed is affected by voltage changes. Weaker batteries with reduced voltage will slow the RPM of the tool, especially at the lowest setting. If your tool appears to be running more slowly than normal, replace the batteries with fresh ones to increase tool speed.

Most applications using the 761 Pet Nail Grooming Tool can be accomplished using the LO speed setting (position 1). The LO speed setting (position 1) is recommended when using the 431 sanding drum

included with the tool. HI speed is needed only for larger animals or nail buffing applications.

The speed of Model 761 is controlled by setting this indicator on the housing.

761 Pet Nail Grooming Tool Accessories

The 761 Pet Nail Grooming Tool can be outfitted with different Dremel accessories to perform a variety of nail grooming tasks. Included below are descriptions of popular Dremel accessories used with the 761 tool.

1/4" Sanding Drum (included)

One #430 Dremel 1/4" sanding drum and four #431 60-grit sanding bands are included with the Dremel Pet Nail Grooming Tool.

Tip: The #430 1/4" sanding drum works best on cats and small to medium sized dogs.

Other Accessories (not included)

1/2" Sanding Drum

The #407 Dremel 1 / 2 sanding drum equipped with a 1 / 2 120-grit or 60-grit sanding band is useful for larger breed dogs.

To replace a band on the Drum Sander, loosen the screw without removing it to contract the drum then slide the old band off. Slide the new sanding band on and then expand the drum by tightening the screw once again.

WARNING Before each use, check to make certain that all components are assembled to accessory shank and that the drum is sufficiently expanded to secure the band during use. If sanding band is loose on the drum during operation it may "fly" off and strike you or bystanders.
