Work area safety

Keep work area clean and well lit. Cluttered

or 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 children and bystanders away while
operating a power tool. Distractions can

cause you to lose control.

Electrical safety

Power tool plugs must match the outlet.
Never modify the plug in any way. Do not
us e a ny adapt e r p lugs wi t h e arthed
(grounded) power tools. Unmodified plugs

and matching outlets will reduce risk of electric
shock.

Avoid body contact with earthed or grounded
surfaces such as pipes, radiators, ranges
and refrigerators. There is an increased risk

of electric shock if your body is earthed or
grounded.

Do not 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
for carrying, pulling or unplugging the power
tool. Keep cord away from heat, oil, sharp
edges or moving parts. Damaged or entangled

cords increase the risk of electric shock.

When operating a power tool outdoors,
use an extension cord suitable for outdoor
use. Use of a cord suitable for outdoor use

reduces the risk of electric shock.

If operating the power tool in a damp location
is unavoidable, use a Ground Fault Circuit
Interrupter (GFCI) protected supply. Use of

an GFCI reduce the risk of electric shock.

Personal safety

Stay alert, watch what you are doing and
us e c o mmon sen se w hen operati ng a
power tool. Do not use a power tool while
you are tired or under the influence of drugs,
alcohol or medication. A moment of inattention

while operating power tools may result in
serious personal injury.

Read all safety warnings and all instructions. Failure to follow the warnings
and instructions may result in electric shock, fire and/or serious injury.

SAVE ALL WARNINGS AND INSTRUCTIONS FOR FUTURE REFERENCE

The term “power tool” in the warnings refers to your mains-operated (corded) power tool or
battery-operated (cordless) power tool.

Safety Symbols

The definitions below describe the level of severity for each signal word. Please read the manual

and pay attention to these symbols.

General Power Tool Safety Warnings

1600A019PE.qxp_Go 5/24/18 3:13 PM Page 2

-3-

Use personal protective equipment. Always
wear eye protection. Protective equipment

such as dust mask, non-skid safety shoes, hard
hat, or hearing protection used for appropriate
conditions will reduce personal injuries.

Prevent unintentional starting. Ensure the
s

wi tch is in the off-p ositi on bef ore
connecting to power source and / or battery
pa ck, pic king up or ca rryi ng the too l.

Carrying power tools with your finger on the
switch or energizing power tools that have the
switch on invites accidents.

Remove any adjusting key or wrench 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

co ntrol of t he p o wer t ool in u n expec t ed
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 forc e the powe r too l. Us e the
correct power tool for your application. The

correct 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

ca n n o t be contro l l e d wit h the switch is
dangerous and must be repaired.

Disconnect the plug from the power source
and/or the battery pack from the power tool
before making any 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
children and do not allow persons unfamiliar
with the power tool or these instructions to
operate the power tool. Power tools are

dangerous in the hands of untrained users.

Maintain power tools. Check 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.

Ma n y a c c idents are ca u s ed b y p o orly
maintained power tools.

Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.

Use the power tool, accessories and tool
bits etc. in accordance with these instructions,
taking into account the working conditions
and the work to be performed. Use of the

power 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 th e ma nufa cturer. A cha rger tha t 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 specific ally
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
small m e t a l objects t h a t can m a k e 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

Have your power tool serviced by a qualified
re p a i r p e r s on u s ing o n ly i d e ntical
replacement parts. This will ensure that the

safety of the power tool is maintained.

Safety Rules for Cordless Screwdrivers

Hold powe r tool by insulated grippi ng
surfaces, when performing an operation
w

here the fastener may contact hidden

wiring. Fasteners contacting a "live" wire may

make exposed metal parts of the power tool
"live" and could give the operator an electric
shock.

Always tur n off power to an e lec tri cal
circuit before working on anything that is
or could be in contact with it, and place a
note on the electrical panel to warn others
not to turn it on. Failure to turn OFF the

power source prior to installation/removal of
cover plates or electrical products can result in
electrical shock, fires, permanent injury and/or
death.

Use clamps or another practical way to
secure and support the workpiece to a
stable platform. Holding the work by hand or

against your body leaves it unstable and may
lead to loss of control.

Do not drill, fasten or break into existing
walls or other blind areas where electrical
wiring ma y ex ist. If this si t u a tion is

unavoidable, disconnect all fuses or circuit
breakers feeding this worksite.

Battery tools are always in an operative
condition. Be aware of the possible hazards.

Always wear safet y g o g g l e s o r e y e
protection when using this tool.

Secure t he work piece, never hold it in
your hand or acros s l egs. The dril ling

action may cause you to lose control of the
workpiece and injury may occur.

W

hen installing a bit, insert the shank of the

bit well within the collet. If the bit is not inserted

deep enough, the grip of the collet over the bit is
reduced and the loss of control is increased.

Do not run the tool while carrying it at
yo ur sid e. A spinning bit could become

entangled with clothing and injury may result.

Do not u s e dul l or d a maged bit s and
accessories. Dull or damaged bits have a

greater tendency to bind in the workpiece.

Some dust creat ed b y

power sanding, sawing,
grinding, drilling, and other construction
activities contains chemicals known to
cause c a n cer, b i r th d e f e c t s o r other
reproductive h arm. Som e e xampl es 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.

Yo u r risk f r o m these expos u r e s varies ,
depending on how often you do this type of
work. To re duc e your exposure to th ese
chemicals: work in a well ventilated area, and
work with approved safety equipment, such
as those d u s t masks t h a t are speciall y
designed to filter out microscopic particles.

Charger Safety Rules

This man ual co ntains ins tru ctions for
battery charger model 510. Do not substitute

any other charger.

Befor e usin g batt ery ch arger, rea d all
instructions and cautionary markings on
(1) battery charger, and (2) product using
battery.

Charge only Dr emel GO. Other types of

cordless tools may burst causing personal
injury and damage.

Charge tool in temperatures above +32
degrees F (0 degrees C) and below +113
degrees F (45 degrees C). Store tool in
locations where temperatur es will not
exceed 120 degrees F (49 degrees C). This

is important to prevent serious damage to the
battery cells.

Do not recha r ge tool in damp or wet
environment. Do not expose charger to rain
or snow. Water entering battery charger may

result in electric shock or fire.

Battery leakage may occur under extreme
usage o r t emp erature c onditions. Avoid
contact with skin and eyes. The battery liquid is

caustic and could cause chemi cal b urns to
tissues. If liquid comes in contact with skin, wash
quickly with soap and water. If the liquid contacts
your eyes, flush them with water for a minimum
of 10 minutes and seek medical attention.

Pl a ce c harge r on fl a t n o nflamm a ble
su r faces and away from fla m mable
materials when recharging tool. Carpeting

and other heat insulating surfaces block proper
air circulation, which may cause overheating of
the charger and tool. If smoke or melting of the

charger or tool is observed, unplug the charger
immediately and do not use the tool or charger.
Contact customer service immediately.

Make sure cord is located so that it will not
be stepped on, tripped over, or otherwise
subjected to damage or stress. Damaged

plug and cord may result in electric shock or
fire.

Disconnect the charger by pulling the plug
ra t her than the cor d. Do not ope rate
charger with damaged cord or plug; have
them replaced immediately. Damaged plug

or cord may result in electric shock or fire.

Do not disassemble charger or operate the
charger if it has received a sharp blow,
been dropped or otherwise damaged in
anyway. Incorrect reassembly or damage may

result in electric shock or fire.

Before each use, check the battery charger,
cable and plug. If damage is detected, do
not use the battery charger. Never open the
battery charger yourself, take it to a Dremel
Fa c tory Se r vice Ce n ter, or q u alifi e d
serviceman only using original spare parts.

Incorrect reassembly may result in electric
shock or fire.

Do not use attachments not recommended
or sold by Dremel. Using attachments not

recommended may result in electric shock or
fire.

Unplug tool from charger when battery in
tool is fully charged. Tool left plugged in the

charger over a long period of time could lead to
tool damage and fire.

Unplug charger from outlet before storage,
attempting any maintenance or cleaning.

Such preventive safety measures reduce the
risk of electric shock or fire.

Keep the battery charger clean by blowing
co mpre ssed ai r o n c harg er vent s a nd
wiping the charger housing with a damp
cloth. Contamination may result in electric

shock or fire.

Replace battery pack if a substantial drop
in operating time per charge is observed.

Battery pack may be nearing the end of its life.

Battery Care

When batteries are not in tool or charger,
keep them away from metal objects. For

example, to protect terminals from shorting
DO NOT place ba tteries in a tool box or
pocket with nails, screws, keys, etc. Fire or
injury may result.

DO NOT PUT BATTERIES INTO FIRE OR
EXPOSE TO H I G H HEAT . They m ay

explode.

Battery leakage may occur under extreme
u

sage or temperature conditions. Avoid

c

ontact with skin and eyes. The battery

l

iquid is caustic and could cause chemical
burn to tissues. If liquid comes in contact with
skin, wash quickly with soap and water. If the
liquid contacts your eyes, flush them with
water for a minimum of 10 minutes and seek
medical attention.

Battery Disposal

Do no t attempt to

disassemble the tool or
remove any component projecting from
the tool. Fire or injury may result. Prior to

disposal, protect exposed terminals with
heavy insulating tape to prevent shorting.
