Prevent unintentional starting. Ensure the
swi t ch is in the off - positi o n before
con nectin g to powe r sou rce and / o r
battery pack, picking up or carrying the
tool. Carrying power tools with your finger

on the switch or energizing power tools that
have the switch on invites accidents.

Rem ove any adjus ting key or wrenc h
before turning the power tool on. A wrench

or a key left attached to a rotating part of
the power tool may result in personal injury.

Do not overreach. Keep proper footing and
balance at all times. This enables better

control of the power tool in unexpected
situations.

Dress properly. Do not wear loose clothing
or jewelry. Keep your hair, clothing and
gloves away from moving parts. Loose

clothes, jewelry or long hair can be caught
in moving parts.

If devices are provided for the connection
of dust extraction and collection facilities,
ensure these are connected and properly
used. Use of dust collection can reduce

dust-related hazards.

▶ Power tool use and care

Do not f orce the po wer tool. Use the
correct power tool for your application.

The cor rec t power tool will do the job
better and safer at the rate for which it was
designed.

Do not use the power tool if the switch
does not turn it on and off. Any power tool

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

Dis c onnect th e plug fr o m the pow e r
source and/or the battery pack from the
pow e r too l befo r e mak i ng an y
adjustments, changing accessories, or
storing power tools. Such preventive safety

measures reduce the risk of starting the
power tool accidentally.

Store idle power tools out of the reach of
chi l dren and do not al low perso n s
unfamiliar with the power tool or these
instructions to operate the power tool.

Power tools are dangerous in the hands of
untrained users.

Mai n tain pow e r tools. C h eck for
misalignment or binding of moving parts,
breakage of parts and any other condition
that may affect the power tool’s operation.
If damaged, have the power tool repaired
before use. Many accidents are caused by

poorly maintained power tools.

Kee p cut t ing tools sharp and clean.

Properly maintain ed cutting tools with
sharp cutting edges are less likely to bind
and are easier to control.

Use the power tool, accessories and tool
bit s etc. in accord a nce with these
ins tructi o ns, taking into acco u nt the
working conditions and the work to be
per formed . U se o f t h e p ower tool for

operations different from those intended
could result in a hazardous situation.

▶ Battery tool use and care

Recharge only with the charger specified
by the manufacturer. A charger that is

suitable for one type of battery pack may
create a risk of fire when used with another
battery pack.

Use power tools only with specifically
designated battery packs. Use of any other

battery packs may create a risk of injury and
fire.

When battery pack is not in use, keep it
away from other metal objects like paper
clips, coins, keys, nails, screws, or other
sma l l metal object s that c an make a
connection from one terminal to another.

Shorting the battery terminals together may
cause burns or a fire.

Under abusive conditions, liquid may be
ejected from the battery, avoid contact. If
contact accidentally occurs, flush with
water. If liquid contacts eyes, additionally
seek medical help. Liquid ejected from the

battery may cause irritation or burns.

▶ Service

Hav e yo u r po w er tool service d by a
qualified repair person using only identical
replacement parts. This will ensure that the

safety of the power tool is maintained.

▶ Safety warnings common for

grinding, sanding, wire
brushing, polishing, carving
or abrasive cutting-off
operations:

This power tool is intended to function as
a grinder, sander, wire brush, polisher,
carving or cut-off 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.

Do n ot use a cce ssories 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.

The RATED SPEED of the accessories must
be at least equal to the operating speed
set t ing marked on the power to ol.

Accessories running faster than their RATED
SPEED can break and fly apart.

The outside diameter and the thickness of
you r accesso ry must b e within t h e
cap a city ratin g o f y o ur power tool .

Incorrectly sized accessories cannot be
adequately controlled.

The arbor size of wheels, sanding drums or
any other accessory must properly fit the
spi n dle or col l et of the power tool.

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.

Mandrel mounted wheels, sanding drums,
cutters or other accessories must be fully
inserted into the collet or chuck. If the

mandrel is insufficiently held and/or the
ov erh ang of the w heel is too long, the
mounted wheel may become loose and be
ejected at high velocity.

Do not use a damaged accessory. Before
each use inspect the accessory such as
abrasive wheels for chips and cracks,
sanding drum for cracks, tear or excess
wear, wire brush fo r loose or cracked
wir e s. If po wer tool or access o ry is
dropped, inspect for damage or install an
undamaged accessory. After inspecting
and inst a lling an access o ry, positi o n
yourself and bystanders away from the
plane of the rotating accessory and run the
power tool at maximum no-load speed for
on e minute. Damaged access ories will

normally break apart during this test time.

We ar personal pro tective equi pmen t.
Depending on application, use face shield,
saf e ty goggles or saf e ty glasses . As
ap propriate, wear dust mask, hear ing
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 o f
fil t rating pa r ticles gen e rated by you r
opera tion. Prolon ged ex posure to high
intensity noise may cause hearing loss.

Keep bystanders a safe distance away
from work area. Anyone entering the work
are a must we a r person a l prote c tive
equipment. Fragments of workpiece or of a

broken accessory may fly away and cause
injury beyond immediate area of operation.

Hold power tool by insulated gripping
sur f aces only, wh en p e rformi n g a n
operation where the cutting accessory may
contact hidden wiring. Cutting accessory

contacting a “live” wire may make exposed
metal parts of the power tool “live” and
could give the operator an electric shock.

Always hold the tool firmly in your hand(s)
during the start-up. The reaction torque of

the motor, as it accelerates to full speed,
can cause the tool to twist.

Use clamp s to suppo r t wor k piece
whenever practical. Never hold a small
workpiece in one hand and the tool in the
other hand while in use. Clamping a small

workpiece allows you to use your hand(s) to
control the tool. Round material such as
dowel rods, pipes or tubing have a tendency
to roll while being cut, and may cause the
bit to bind or jump toward you.

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.

Never lay the power tool down until the
accessory has come to a complete stop.

The sp inning ac c essory ma y grab the
surface and pull the power tool out of your
control.

After changing the bits or making any
adjustments, make sure the collet nut,
chuck or any other adjustment devices are
se curely tight ened . Loose a djust ment

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

Safety Rules for Rotary Tools

Do not run the power tool while carrying it
at your side. Accidental contact with the

spi n ning access o r y could sna g yo ur
clothing, pulling the accessory into your
body.

Regularly clean the power tool’s air vents.

The motor’s fan will draw the dust inside
the housing and excessive accumulation of
pow d ered met a l may caus e electri c al
hazards.

Do not oper a te the power tool near
flammable materials. Sparks could ignite

these materials.

Do not use accessories that require liquid
coo l ants. Using water o r other liquid

coolants may result in electrocution or
shock.

Use only in well-ventilated area. Working in
a safe environment reduces risk of injury.

Allow for sufficient space, at least 6”,
between your hand and the spinning bit.
Do not reach in the area of the spinning
bit. The proximity of the spinning bit to your

hand may not always be obvious.

Do not touch the bit or collet after use.

After use the bit and collet are too hot to be
touched by bare hands.

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.

▶ 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
sna g ging caus e s ra pid stall i ng of the
rotating accessory which in turn causes the
uncontrolled power tool to be forced in the
dir e ction opposite of the accesso r y’s
rotation.

For exampl e , if an abr a sive 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
kickout. 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.

Maintain a firm grip on the power tool and
position your body and arm to allow you to
resist kickback forces. The operator can

con t rol kickba c k f o rces, if prope r
precautions are taken.

Use special care when working corners,
sha rp edges etc . Av oid bounc ing and
snagging the accessory. Corners, sharp

edges or bouncing have a tendency to snag
the rotating accessory and cause loss of
control or kickback.

Do not attach a toothed saw blade. Such
blades create frequent kickback and loss of
control.

Always feed the bit into the material in the
sa me directi on as the cuttin g edge is
exiting from the material (which is the
same direction as the chips are thrown).

Feeding the tool in the wrong direction
causes the cutting edge of the bit to climb
out of the work and pull the tool in the
direction of this feed.

When using rotary files, cut-off wheels,
high-speed cutters or tungsten carbide
cutters, always have the work securely
clamped. These wheels will grab if they

become slightly canted in the groove, and
can kickback. When a cut-off wheel grabs,
the wheel itself usually breaks. When a
rotary file, high-speed cutter or tungsten
carbide cutter grabs, it may jump from the
groove and you could lose control of the
tool.

▶ Safety warnings specific for

grinding and abrasive cutting­off operations:

Use o n ly wheel t y pes that a r e
recommended for your power tool and
only for recommended applications. For
example: do not grind with the side of a
cut-off wheel. Abrasive cut-off wheels are

intended for peripheral grinding, side forces
applied to these wheels may cause them to
shatter.

For threaded abrasive cones and plugs use
only undamaged wheel mandrels with an
unrelieved shoulder flange that are of
correct size and length. Proper mandrels

will reduce the possibility of breakage.

Do not jam a cut-off wheel or apply
excessive pressure. Do not attempt to
mak e an ex c essive d epth of cut.

loading and susceptibility to twisting or
snagging of the wheel in the cut and the
possibility of kickback or wheel breakage.

Do not position your hand in line with and
behind the rotating wheel. When the wheel,

at the point of operation, is moving away
from your hand, the possible kickback may
propel the spinning wheel and the power
tool directly at you.

When wheel is pinched, snagged or when
interrupting a cut for any reason, switch
off the power tool and hold the power tool
motionless until the wheel comes to a
complete stop. Never attempt to remove
the cut-off wheel from the cut while the
wheel is in motion otherwise kickback may
occur. Investigate and take corrective action

to eliminate the cause of wheel pinching or
snagging.

Do not restart the cutting operation in the
workpiece. Let the wheel reach full speed
and carefully re-enter the cut. The wheel

may bind, walk up or kickback if the power
tool is restarted in the workpiece.

Sup p ort pane l s or any o v ersize d
workpiece to minimize the risk of wheel
pinching and kickback. Large workpieces

ten d to sa g und e r the i r own weight .
Sup p orts m ust b e placed under t he
workpiece near the line of cut and near the

edge of the workpiece on both sides of the
wheel.

Use extra caution when making a pocket
cut into existing walls or other blind
areas. The protruding wheel may cut gas or

water pipes, electrical wiring or objects that
can cause kickback.

▶ Safety warnings specific for

wire brushing operations:

Be aware that wire bristles are thrown by
the brush even during ordinary operation.
Do not overstress the wires by applying
exces sive load to th e brus h. Th e wire

bristles can easily penetrate light clothing
and/or skin.

Allow brushes to run at operating speed
for at least one minute before using them.
During this time no one is to stand in front
or in line with the brush. Loose bristles or

wires will be discharged during the run-in
time.

Direct the discharge of the spinning wire
brush away from you. Small particles and

tiny wire fragments may be discharged at
hig h velocity du ring the us e of these
brushes and may become imbedded in your
skin.

▶ Rotary Tool Introduction

The Rotary Tool has a small, powerful
electric motor, is comfort able in the
hand, and is made to accept a large
variety of accessories including abrasive
whe e ls, dr ill bi t s, wi r e bru s hes,
polishers, engraving cutters, cutting
wheels. As you be come familiar with the
range of accessories and their uses, you
will learn just how versatile the Rotary
Tool is. You’ll see dozens of uses you
hadn’t thought of before.

The real secret of the Rotary Tool is its
speed. To understand the advantages of
its high speed, you have to know that
the standard portable electric drill runs
at speeds up to 2,800 revolutions per
minute. The Rotary Tool operates at
speeds up to 25,000 revolutions per
minute. The typical electric drill is a low­speed, high torque tool; the Rotary Tool
is just the opposite – a high-speed, low
torque tool. The major difference to the
user is that in the high speed tools, the

Introduction

▶ Balancing Accessories

For precision work, it is important that
all acc e ssori e s b e i n goo d bal ance
(much the same as the tires on your
automobile). To true up or balance an
accessory, slightly loosen collet nut and
give the accessory or collet a 1/4 turn.
Re tighten collet nut and run the Rotary
Tool. You should be able to tell by the
so und and fe el if you r a ccessor y i s

running in balance. Continue adjusting
in this fashion unt il best balance is
ach i eved. T o maint a in bala n ce on
abrasive wheel points, before each use,
with the wheel point secured in the
collet, turn on the Rotary Tool and run
the 415 Dressing Stone lightly against
the revolving wheel point. This removes
high spots and trues up the wheel point
for good balance.

Operating Speeds

To select the right speed for each job, use a
practice piece of material.

▶ “On/Off” / Speed Switch

The to ol is cont r olled by th e blue
“On/Off” / Speed Switch 8 located on
the topside of the recessed part of the
housing (Fig. 6).

TO TURN THE TOOL “ON” gently slide
the switch 8 up with your thumb. The
tool will start working at a speed of
8,000 RPM.

The spee d may be adjus ted during
operation by continuing to gently slide
the switch 8 up with your thumb.

▶ Settings for Approximate

Revolutions:

You can refer to the charts on pages
28–31 to determine the proper speed,
based on the material being worked and
the type of accessory being used. These
charts enable you to select both the
correct accessory and the op tim um
speed at a glance.

▶ Electronic Monitoring

Your tool is equipped with an internal
electronic monitoring system that helps
to m a ximize m otor an d battery
performance by limiting the current to

the tool when overl o ad a n d sta l l
conditions occur. If you stall the tool for
too long, or bind the bit in a work piece,
especially at high speeds, the tool will
automatically turn itself off thanks to
th e fallback built int o it. Onc e this
ha ppens, slide speed swi tch to “0”
position, simply take the tool out of the
material you were stalled in, turn it back
on again, adjust the speed if necessary,
and continue using it. When the battery
is close to empty, the tool may shut
down automatically more frequently
than normal. If this happens, it is time
to recharge the tool.

▶ Needs for Slower Speeds

Cer t ain materia l s, h owever , (som e
plastics and precious metals, for ex ­ample) require a relatively slow speed
because at high speed the friction of the
accessory generates heat and may cause
damage to the material.

Slo w spe eds (15,00 0 R P M o r les s )
usually are best for polishing operations
employing the felt polishing ac ces sories.
They may also be best for working on
de li cate proj ects as “eggery” work,
delicate wood carving and fragile model
parts. All brushing applications require

lower speeds to avoid wire discharge
from the holder.

Higher speeds are better for carving,
cu tting, sha ping, cutting da does o r
rabbets in wood.

Hardwoods, metals and glass require
hig h speed op eratio n , and d r i lling
should also be done at high speeds.

Many applications and accessories in
our line will provid e the best
per f ormanc e at full s peed, but f or
certain materials, applications, and
accessories, you need slower speeds,
which is the reason our variable speed
models are available.

To aid you in determining the optimum
operational speed for differ ent materials
an d d iffer ent acce ssor ies, we have
co nstru cted a seri es of table s t hat
appear on page 28–31. By referring to
the s e t ables, you can disco v er t he
recommended speeds for each type of
accessory. Look these tables over and
become familiar with them.

Operating Speeds

material is to practice for a few minutes
on a piece of scrap, even after referring
to the chart. You can quickly learn that a
slower or faster speed is more effective
just by observing what hap pens as you
make a pass or two at different speeds.
When working with plastic, for example,
sta r t at a slow rate of speed and
increase the speed until you observe
that the plastic is melting at the point of
contact. Then reduce the speed slight ly
to get the optimum working speed.

Some rules of thumb in regard to speed:

1. Plastic and other materials that melt
at low temperatures should be cut at
low speeds.

2. Polishing, buffing and cleaning with
any type of bristle brush must be
done at speeds not greater than
15,000 RPM to prevent damage to
the brush from bristles flying toward
operator.

3. Wood should be cut at high speed.

4. Iron or steel should be cut at high
speed. If a high speed steel cutter
starts to chatter — this normally
means it is running too slow.

5. Aluminum, copper alloys, lead alloys,
zinc alloys and tin may be cut at

various speeds, depending on the
type of cut ting bein g done. Use
paraffin or other suitable lubricant on
the cutter to prevent the cut material
from adhering to the cutter teeth.

Increasing the pressure on the tool is
not th e an swer when it i s no t
per f orming as you think i t shoul d .
Perhaps you should be using a different
accessory, and perhaps an adjustment
in spee d w ould solv e t he p roble m.
Leaning on the tool does not help.

Your Dremel Lite 7760 can be used with
all of the Dremel accessories, except
router bits. While the tool will work with
cut-off wheels, the reduced speed of
this tool will not allow them to perform
optimally. They can be used to cut soft
materials such as wood or plastic, but
cutting metals is not recommended.

Let speed do the work!
