GENERAL SAFETY RULES USA0021
(For All Tools)
WARNING! Read and understand all instructions. Failure
tofollow all instructions listedbelow, may result inelectric
shock, fire and/or serious personal injury.
SAVE THESE INSTRUCTIONS
Work Area
1. Keepyour work area cleanand well lit. Clutteredbenches and dark areas invite
accidents.
2. Do not operate power tools in explosiveatmospheres, such as in the presence
of flammable liquids, gases, or dust. Power tools create sparks which may
ignite the dust or fumes.
3. Keep bystanders, children, and visitors away while operating a power tool.
Distractions can cause you to lose control.
Electrical Safety
4. Double Insulatedtools are equipped with a polarized plug (onebladeis 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
E3 eliminates the need for the three
wire grounded power cord and grounded power supply system.
5. 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.
6. DonotexDose Dower tools torainor wet conditions. Water entering a Dower
-.
tool will increase the risk of electric shock.
Do not abuse the cord. Never use the cordtocarry the tools or pullthe plug
from an outlet. Keep cordaway from heat,
oil, sharp edges or movingparts.
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.
Personal Safety
9. Stay alert, watch what you are doingandusecommon sense when operating
a power tool.
Do not use tool while tired or under the influence of drugs,
alcohol, or medication.
A moment of inattentionwhile operating power tools
may result
in serious personal injury.
IO. Dress properly. Donotwear loose clothing orjewelry. Contain longhair. Keep
your hair, clothing, andglovesaway from movingparts. Loose clothes, jewelry
or long hair can be caught
in moving parts.

11. Avoid accidental starting. Be sure switch is off before plugging in. Carrying
tools withyour finger onthe switch or plugging in
tools that have the switch
on invites accidents.
12. Remove adjusting keys or wrenches before turning the tool on. A wrench
or
a key that is left attached toa rotatingpart of thetool may result inpersonal
injury.
13. Do notoverreach.Keepproper footingand balanceatalltimes. Proper footing
and balance enables better control of the tool in unexpected situations.
14. 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
15. Use clamps or other practical way tosecure 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.
16. Do notforce 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.
17. 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.
18. Disconnect the plugfrom the power source before making any adjustments,
changing accessories, or storing the tool. Such preventive safety measures
reduce the risk of starting the tool accidentally.
19. Store idle tools out of reach of children and other untrained persons. Tools
are dangerous in the hands of untrained users.
20. Maintain tools with care. Keep cutting tools sharp and clean. Properly
maintained tools, with sharp cuttingedges are less likely to bind and are easier
to control.
21. Check for misalignment or binding of moving parts, breakage of parts, and
any other condition that may affect the tools operation. If damaged, have
the tool serviced before using. Many accidents are caused by poorly
maintained tools.
22. 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
23. Tool service must be performed only by qualified repair personnel. Service
or maintenance performed by unqualified personnel could result in a risk of
injury.
24. When servicing a tool, use only identical replacement parts. Follow
instructions
in the Maintenancesection of this manual. Use of unauthorized
parts or failure tofollow Maintenance Instructions may create
a risk of electric
shock or injury.

Installingor removingdrill bit
To installthe bit, place it inthe chuck as far
as it will go. Tighten the chuck by hand.
Place the chuck key in each of the three
holes and tighten clockwise. Be sure to
tighten allthree chuck holes evenly.
To remove the bit, turn the chuck key
counterclockwise in just one hole, then
loosenthe chuck by hand.
After usingthe chuck key, be sure to return
it to the original position.
Installingor removingangle attachment
CAUTION:
Always be surethat the tool
is switched off and pluggedbefore installing or removing the
angle attachment.
The angle headhas
a spindle oneach end.
For higher speed operation, attach the drill
chuck to the end marked “HIGH”. The
higher speed is better suited for drilling
smaller diameter holes.
For lower speed operation, attach the drill
chuck to the end marked
”LOW”. The
lower speed isbest utilizedfor drilling larger
diameter holes.
The tool is facton/ assembled with the
chuck on spindle end marked ”HIGH”.
To change to the
“LOW” speed, proceed
as follows:
To remove the drill chuck, first open the
chuck jaws completely and placethe chuck

about
10 times so that they can be
removedtogether.
Loosen the bolts of the joint
by the hex
wrench and remove the angle housing,the
joint and the socket.
To install the socket and the joint, fit the
socket to the spindle
so that the two faces
are fitted perfectly. Then install the joint.
For higher speed operation, fit the angle
housing marked
"LOW" to the joint.
For lower speed operation, fit the angle
housingmarked
"HIGH" to the joint.

OPERATION
Drilling operation
*Drillinginwood
When drilling in wood, best results are obtained with wood drills equippedwith
a guide
screw. The guide screw makes drilling easier by pullingthe bit into the workpiece.
To preventthe bitfrom slipping when starting a hole, makean indentation with a center-
punchand hammer
at the point to be drilled. Place the point of the bit in the indentation
and start drilling.
Use a cutting lubricant when drilling metals. The exceptions are iron and brass which
should be drilled dry.
*Drilling in metal
Holding tool
When drilling a large hole with a hole saw, etc., the side grip (auxiliaryhandle) should be
usedas
a brace to maintainsafe control of the tool.
CAUTIO
N :
*Pressing excessively on the tool will not speed up the drilling. In fact. this excessive
pressurewill only serve to damage the tip
of your bit, decreasethe toolperformanceand
shorten the service lifeof the tool.
*There is
a tremendous force exerted on the tool/bit at the time of hole breakthrough.
Holdthe tool firmly andexert care when the bit beginsto breakthrough the workpiece.
*Always grip the small workpiece firmly with
a vise or a holding means.
*A stuck bit can be removedsimply by setting the reversing switch to reverse rotation in
order to back out. However, the toolwill pullaway easily unlessyou hold it firmly before
startingthe tool.
