2.
3.
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 flammables.
Keep bystanders, children, and visitors away while operating a power tool.
Distractions can cause you to lose control. Protect others in the work area from
debris such as chips and sparks. Provide barriers or shields as needed.
ELECTRICAL SAFETY
4.
Grounded tools must be plugged into an outlet properly installed and
grounded in accordance with all codes and ordinances. Never remove the
grounding prong or modify the plug in any way. Do not use any adapter
plugs. Check with a qualified electrician if you are in doubt as to whether
the outlet is properly grounded. If the tools should electrically malfunction or
break down, grounding provides a low resistance path to carry electricity away
from the user.
5.
6.
Double insulated tools are equipped with a polarized plug (one blade is
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
eliminates the need for the
three wire grounded power cord and grounded power supply system.
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.
7.
8.
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 Power Cord. Never use the Power Cord to carry the tools
or pull the Plug from an outlet. Keep the Power Cord away from heat, oil,
sharp edges, or moving parts. Replace damaged Power Cords immediately.
Damaged Power Cords increase the risk of electric shock.
9.
When operating a power tool outside, use an outdoor extension cord
marked “W-A” or “W”. These extension cords are rated for outdoor use, and
reduce the risk of electric shock.

PERSONAL SAFETY
10.
Stay alert. Watch what you are doing, and use common sense when
operating a power tool. Do not use a power 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.
11.
12.
13.
14.
15.
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 the Power Switch is off before plugging
in. Carrying power tools with your finger on the Power Switch, or plugging in
power tools with the Power Switch on, invites accidents.
Remove adjusting keys or wrenches before turning the power tool on. A
wrench or a key that is 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. Proper
footing and balance enables better control of the power tool in unexpected
situations.
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
16.
Use clamps (not included) or other practical ways to secure 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.
17.
18.
Do not force the 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 the power tool if the Power Switch does not turn it on or off.
Any tool that cannot be controlled with the Power Switch is dangerous and must
be replaced.
19.
20.
Disconnect the Power Cord Plug from 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.
Store idle tools out of reach of children and other untrained persons. Tools
are dangerous in the hands of untrained users.

21.
22.
Maintain tools with care. Keep cutting tools sharp and clean. Properly
maintained tools with a sharp cutting edge are less likely to bind and are easier
to control. Do not use a damaged tool. Tag damaged tools “Do not use” until
repaired.
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.
23.
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
24.
25.
Tool service must be performed only by qualified repair personnel. Service
or maintenance performed by unqualified personnel could result in a risk of injury.
When servicing a tool, use only identical replacement parts. Follow
instructions in the “Inspection, Maintenance, And Cleaning” section of this
manual. Use of unauthorized parts or failure to follow maintenance instructions
may create a risk of electric shock or injury.
SPECIFIC SAFETY RULES
1.
Hold tool by insulated gripping surfaces when performing an operation
where the cutting tools may contact hidden wiring or its own cord. Contact
with a ‘live’ wire will make exposed metal parts of the tool ‘live’ and shock the
operator.

GROUNDED TOOLS: TOOLS WITH THREE PRONG PLUGS
1.
Tools and equipment marked with “Grounding Required” have a three wire cord
and three prong grounding plug. The plug must be connected to a properly
grounded outlet. If the tool or equipment should electrically malfunction or break
down, grounding provides a low resistance path to carry electricity away from the
user, reducing the risk of electric shock. (See Figure A.)
2.
3.
The grounding prong in the plug is connected through the green wire inside the
cord to the grounding system in the tool. The green wire in the cord must be the
only wire connected to the tool’s grounding system and must never be attached
to an electrically “live” terminal. (See Figure A.)
Your tool must be plugged into an appropriate outlet, properly installed and
grounded in accordance with all codes and ordinances. The plug and outlet
should look like that in the following illustration. (See Figure A.)
FIGURE A
DOUBLE INSULATED TOOLS: TOOLS WITH TWO PRONG PLUGS
1.
2.
Tools marked “Double Insulated” do not require grounding. They have a special
double insulation system which satisfies OSHA requirements and complies with
the applicable standards of Underwriters Laboratories, Inc., the Canadian
Standard Association, and the National Electrical Code. (See Figure B.)
Double insulated tools may be used in either of the 120 volt outlets shown in the
following illustration. (See Figure B.)

FIGURE B
EXTENSION CORDS
1.
2.
Grounded tools require a three wire extension cord. Double Insulated tools
can use either a two or three wire extension cord.
As the distance from the supply outlet increases, you must use a heavier gauge
extension cord. Using extension cords with inadequately sized wire causes a
serious drop in voltage, resulting in loss of power and possible tool damage.
(See Figure C, next page.)
3.
The smaller the gauge number of the wire, the greater the capacity of the cord.
For example, a 14 gauge cord can carry a higher current than a 16 gauge cord.
(See Figure C.)
4.
5.
When using more than one extension cord to make up the total length, make
sure each cord contains at least the minimum wire size required.
(See Figure C.)
If you are using one extension cord for more than one tool, add the nameplate
amperes and use the sum to determine the required minimum cord size.
(See Figure C.)
6.
7.
If you are using an extension cord outdoors, make sure it is marked with the
suffix “W-A” (“W” in Canada) to indicate it is acceptable for outdoor use.
Make sure your extension cord is properly wired and in good electrical condition.
Always replace a damaged extension cord or have it repaired by a qualified
electrician before using it.
8.
Protect your extension cords from sharp objects, excessive heat, and damp or
wet areas.

2.
WARNING! Always make sure the Trigger (30) is in its “OFF” position, and
unplug the Power Cord/Plug (31) from its 120 volt electrical outlet before
performing any inspection, adjustments, maintenance, or cleaning.
Before each use, inspect the general condition of the Drill. Check for loose
screws, misalignment or binding of moving parts, cracked or broken parts,
damaged electrical wiring, loose, cracked, or bent drill bits, and any other
condition that may affect its safe operation. If abnormal noise or vibration occurs,
have the problem corrected before further use.
Do not use damaged equipment.
3.
4.
Daily: With a soft brush, cloth, or vacuum, remove all dust and debris from the
Drill. Then, use a premium quality, lightweight machine oil to lubricate
all external moving parts.
To replace the Carbon Brushes: It may become necessary at sometime to
replace the two Carbon Brushes (19) when the Motor performance decreases, or
stops working completely. The Carbon Brushes are located on each side of
the Motor Housing (4) and Motor Housing Cover (17). To do so, remove the
two Brush Holder Covers (18). Then, remove the two Carbon Brushes from the
Brush Holders (20). If the Carbon Brushes are worn down more than 1/2,
replace both Carbon Brushes. If, however, the Carbon Brushes are just dirty they
may be cleaned by rubbing them with a pencil eraser. When installing the
Carbon Brushes, make sure the carbon portion of the Carbon Brushes contact
the Motor Armature, and that the springs face away from the Motor. Also, make
sure the springs operate freely. After cleaning or replacement, replace the Brush
Holders. NOTE: New Carbon Brushes tend to arc or spark when first used
until they wear and conform to the Motor’s Armature. (See Figure E, next page.)
