WARNING
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.
Stay alert, watch what you are doing, and use
common sense when operating a power tool. Do
Read and understand all instructions. Failure to follow all instructions listed below, may
result in electric shock, fire and/or serious personal injury.

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.

Operation Instructions
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
. Nail grooming does not have to be a stress-
owner
ful 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’
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. Y
ou 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.
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.
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 injur
y 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.
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.

Operating Speeds For Accessories
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.
eaker batteries with reduced voltage will slow the
W
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
