GENERAL SAFETY RULES  
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 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 these devices can  
reduce dust-related hazards.  
WARNING:  
Read all instructions. Failure to follow all  
instructions listed below may result in electric  
shock, fire and/or serious injury. The term “power  
tool” in all of the warnings listed below refers  
to your mains-operated (corded) power tool or  
battery-operated (cordless) power tool.  
SAVE THESE INSTRUCTIONS  
WORK AREA SAFETY  
Keep work area clean and well lit. Cluttered or dark  
areas invite accidents.  
Do not operate power tools in explosive atmo-  
spheres, such as in the presence of flammable  
liquids, gases or dust. Power tools create sparks which  
may ignite the dust or fumes.  
Do not wear loose clothing or jewelry. Contain long  
hair. Loose clothes, jewelry, or long hair can be drawn  
into air vents.  
Do not use on a ladder or unstable support. Stable  
footing on a solid surface enables better control of the  
power tool in unexpected situations.  
Keep children and bystanders away while operating a  
power tool. Distractions can cause you to lose control.  
ELECTRICAL SAFETY  
POWER TOOL USE AND CARE  
Power tool plugs must match the outlet. Never modify  
the plug in any way. Do not use any adapter plugs with  
earthed (grounded) power tools. Unmodified plugs and  
matching outlets will reduce risk of electric shock.  
Do not force the power tool. Use 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 cannot be controlled  
with 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. Many accidents are caused by poorly  
maintained power tools.  
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 elec-  
tric 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 exten-  
sion cord suitable for outdoor use. Use of a cord suit-  
able for outdoor use reduces the risk of electric shock.  
PERSONAL SAFETY  
Stay alert, watch what you are doing and use  
common sense when operating 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.  
Use safety equipment. Always wear eye protec-  
tion. Safety equipment such as dust mask, non-skid  
safety shoes, hard hat, or hearing protection used for  
appropriate conditions will reduce personal injuries.  
Keep cutting tools sharp and clean. Properly main-  
tained 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 and in the manner  
intended for the particular type of power tool, 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.  
Avoid accidental starting. Ensure the switch is in the  
off-position before plugging in. Carrying power tools  
with your finger on the switch or plugging in power tools  
that have the switch on invites accidents.

GENERAL SAFETY RULES  
When servicing a power tool, use only identical  
replacement parts. Follow instructions in the  
Maintenance section of this manual. Use of  
unauthorized parts or failure to follow Maintenance  
instructions may create a risk of shock or injury.  
SERVICE  
Have your power tool serviced by a qualified repair  
person using only identical replacement parts. This will  
ensure that the safety of the power tool is maintained.  
WARNING!  
To reduce the risk of injury, user must read  
instruction manual.  
SPECIFIC SAFETY RULES  
Use auxiliary handles supplied with the tool. Loss of  
be carefully checked to determine that it will operate  
properly and perform its intended function. Check for  
alignment of moving parts, binding of moving parts,  
breakage of parts, mounting, and any other conditions  
that may affect its operation. A guard or other part that  
is damaged should be properly repaired or replaced  
by an authorized service center. Following this rule will  
reduce the risk of shock, fire, or serious injury.  
control can cause personal injury.  
Hold power tools by insulated gripping surfaces when  
performing an operation where the cutting tool 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.  
Know your power tool. Read operator’s manual  
carefully. Learn its applications and limitations, as well  
as the specific potential hazards related to this tool.  
Following this rule will reduce the risk of electric shock,  
fire, or serious injury.  
Make sure your extension cord is in good condi-  
tion. When using an extension cord, be sure to use  
one heavy enough to carry the current your product  
will draw. A wire gauge size (A.W.G.) of at least 14 is  
recommended for an extension cord 50 feet or less  
in length. A cord exceeding 100 feet is not recom-  
mended. If in doubt, use the next heavier gauge. The  
smaller the gauge number, the heavier the cord. An  
undersized cord will cause a drop in line voltage resulting  
in loss of power and overheating.  
Always wear safety glasses. Everyday eyeglasses  
have only impact-resistant lenses; they are NOT safety  
glasses. Following this rule will reduce the risk of serious  
personal injury.  
Protect your lungs. Wear a face or dust mask if the  
operation is dusty. Following this rule will reduce the risk  
of serious personal injury.  
Inspect for and remove all nails from lumber before  
using this tool. Following this rule will reduce the risk of  
serious personal injury.  
Protect your hearing. Wear hearing protection during  
extended periods of operation. Following this rule will  
reduce the risk of serious personal injury.

tool, a guard or other part that is damaged should  
WARNING:  
Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals  
known to cause cancer, birth defects or other reproductive harm. Some examples 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.  
Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure  
to these chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust  
masks that are specially designed to filter out microscopic particles.

ELECTRICAL  
DOUBLE INSULATION  
EXTENSION CORDS  
Double insulation is a concept in safety in electric power  
tools, which eliminates the need for the usual three-wire  
grounded power cord. All exposed metal parts are isolated  
from the internal metal motor components with protect-  
ing insulation. Double insulated tools do not need to be  
grounded.  
When using a power tool at a considerable distance from  
a power source, be sure to use an extension cord that has  
the capacity to handle the current the tool will draw. An  
undersized cord will cause a drop in line voltage, resulting in  
overheating and loss of power. Use the chart to determine  
the minimum wire size required in an extension cord. Only  
round jacketed cords listed by Underwriter’s Laboratories  
(UL) should be used.  
WARNING:  
When working outdoors with a tool, use an extension  
cord that is designed for outside use. This type of cord is  
designated with “WA” on the cord’s jacket.  
The double insulated system is intended to protect  
the user from shock resulting from a break in the  
tool’s internal wiring. Observe all normal safety  
precautions to avoid electrical shock.  
Before using any extension cord, inspect it for loose or  
exposed wires and cut or worn insulation.  
NOTE: Servicing of a tool with double insulation requires  
extreme care and knowledge of the system and should be  
performed only by a qualified service technician. For service,  
we suggest you return the tool to your nearest authorized  
service center for repair. Always use original factory replace-  
ment parts when servicing.

OPERATION  
DRILLING  
See Figure 8.  
Depress and release the switch trigger to be sure the drill is  
in the OFF position before connecting it to power supply.  
Check the direction of rotation selector for correct setting  
(forward or reverse).  
Secure the material to be drilled in a vise or with clamps  
to keep it from turning as the drill bit rotates.  
Plug the drill into power supply source.  
Hold the drill firmly and place the bit at the point to be  
drilled.  
Depress the switch trigger to start the drill. Do not lock  
the switch ON for jobs where the drill may need to be  
stopped suddenly.  
Move the drill bit into the workpiece applying only enough  
pressure to keep the bit cutting. Do not force the drill or  
apply side pressure to elongate a hole. Let the drill and  
bit do the work.  
WARNING:  
Be prepared for binding or bit breakthrough. When  
these situations occur, drill has a tendency to grab  
and kick opposite to the direction of rotation and  
could cause loss of control when breaking through  
material. If not prepared, this loss of control can  
result in possible serious injury.  
When drilling hard smooth surfaces use a center punch to  
mark the desired hole location. This will prevent the drill bit  
from slipping off center as the hole is started.  
Fig. 8  
When drilling metals use a light oil on the drill bit to keep it  
from overheating. The oil will prolong the life of the bit and  
increase the drilling action.  
METAL DRILLING  
For maximum performance, use high speed steel bits for  
metal or steel drilling.  
If the bit jams in the workpiece or if the drill stalls, stop the  
tool immediately. Remove the bit from the workpiece and  
determine the reason for jamming.  
Begin drilling at a very low speed to prevent the bit from  
slipping off the starting point.  
WOOD DRILLING  
For maximum performance, use high speed steel bits for  
wood drilling.  
Maintain a speed and pressure which allows cutting  
without overheating the bit. Applying too much pressure  
will:  
Begin drilling at a very low speed to prevent the bit from  
slipping off the starting point. Increase the speed as the  
drill bit bites into the material.  
• Overheat the drill;  
• Wear the bearings;  
• Bend or burn bits; and  
When drilling through holes, place a block of wood behind  
the workpiece to prevent ragged or splintered edges on  
the back side of the hole.  
• Produce off-center or irregular-shaped holes.  
When drilling large holes in metal, start with a small bit,  
then finish with a larger bit. Also, lubricate the bit with oil  
to improve drilling action and increase bit life.

commercial solvents and may be damaged by their use. Use  
clean cloths to remove dirt, dust, oil, grease, etc.  
WARNING:  
HEX  
KEY  
Do not at any time let brake fluids, gasoline,  
petroleum-based products, penetrating oils, etc.,  
come in contact with plastic parts. Chemicals can  
damage, weaken or destroy plastic which may  
result in serious personal injury.  
Fig. 9  
Electric tools used on fiberglass material, wallboard,  
spackling compounds, or plaster are subject to accelerated  
wear and possible premature failure because the fiberglass  
chips and grindings are highly abrasive to bearings, brushes,  
commutators, etc. Consequently, we do not recommend  
using this tool for extended work on these types of materi-  
als. However, if you do work with any of these materials, it is  
extremely important to clean the tool using compressed air.  
LUBRICATION  
All of the bearings in this tool are lubricated with a sufficient  
amount of high grade lubricant for the life of the unit under  
normal operating conditions. Therefore, no further lubrica-  
tion is required.  
CHUCK REMOVAL  
See Figures 9 - 10.  
SCREWDRIVER
