GENERAL SAFETY RULES  
nDo not overreach. Keep proper footing and balance  
WARNING!  
at all times. Proper footing and balance enable better  
control of the tool in unexpected situations.  
READ AND UNDERSTAND ALL INSTRUCTIONS. Fail-  
ure to follow all instructions listed below, may result in  
electric shock, fire and/or serious personal injury.  
nUse safety equipment. Always wear eye protection.  
Dust mask, non-skid safety shoes, hard hat, or hearing  
protection must be used for appropriate conditions.  
nDo not wear loose clothing or jewelry. Contain long  
hair. Loose clothes, jewelry, or long hair can be drawn  
into air vents.  
SAVE THESE INSTRUCTIONS  
WORK AREA  
nDo not use on a ladder or unstable support. Stable  
footing on a solid surface enables better control of the  
tool in unexpected situations.  
nKeep your work area clean and well lit. Cluttered  
benches and dark areas invite accidents.  
nDo 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.  
nKeep bystanders, children, and visitors away while  
operating a power tool. Distractions can cause you to  
lose control.  
TOOL USE AND CARE  
nUse clamps or other practical way to secure and sup-  
port the workpiece to a stable platform. Holding the  
work by hand or against your body is unstable and may  
lead to loss of control.  
nDo not force 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.  
nDo not use tool if switch does not turn it on or off.  
A tool that cannot be controlled with the switch is  
dangerous and must be repaired.  
nDisconnect battery pack from tool or place the switch  
in the locked or off position before making any adjust-  
ments, changing accessories, or storing the tool. Such  
preventive safety measures reduce the risk of starting the  
tool accidentally.  
nStore idle tools out of reach of children and other  
untrained persons. Tools are dangerous in the hands  
of untrained users.  
nWhen battery pack is not in use, keep it away from  
other metal objects like: paper clips, coins, keys, nails,  
screws, or other small metal objects that can make  
a connection from one terminal to another. Shorting  
the battery terminals together may cause sparks, burns,  
or a fire.  
nMaintain tools with care. Keep cutting tools sharp  
and clean. Properly maintained tools with sharp  
cutting edges are less likely to bind and are easier to  
control.  
nCheck 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.  
ELECTRICAL SAFETY  
nA battery operated tool with integral batteries or a  
separate battery pack must be recharged only with  
the specified charger for the battery. A charger that  
may be suitable for one type of battery may create a risk  
of fire when used with another battery.  
nUse battery operated tool only with specifically  
designated battery pack. Use of any other batteries  
may create a risk of fire.  
nUse battery only with charger listed.

nDo not abuse the cord. Never use the cord to carry  
the charger. Keep cord away from heat, oil, sharp  
edges, or moving parts. Replace damaged cords  
immediately. Damaged cords may create a fire.  
PERSONAL SAFETY  
nStay alert, watch what you are doing and use  
common sense when operating a power tool. Do not  
use 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.  
nDress 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.  
nAvoid accidental starting. Be sure switch is in the  
locked or off position before inserting battery pack.  
Carrying tools with your finger on the switch or inserting  
the battery pack into a tool with the switch on invites ac-  
cidents.  
nRemove adjusting keys or wrenches before turning  
the tool on. A wrench or a key that is left attached to a  
rotating part of the tool may result in personal injury.  
nUse only accessories that are recommended by the  
manufacturer for your model. Accessories that may be  
suitable for one tool may create a risk of injury when used  
on another tool.  
n Keep the tool and its handle dry, clean and free from  
oil and grease. Always use a clean cloth when clean-  
ing. Never use brake fluids, gasoline, petroleum-based  
products, or any strong solvents to clean your tool. Fol-  
lowing this rule will reduce the risk of loss of control and  
deterioration of the enclosure plastic.

during a power surge.  
nMake sure cord is located so that it will not be stepped  
on, tripped over, come in contact with sharp edges  
or moving parts or otherwise subjected to damage or  
stress. This will reduce the risk of accidental falls, which  
could cause injury, and damage to the cord, which could  
result in electric shock.  
nRisk of electric shock. Do not touch uninsulated portion  
of output connector or uninsulated battery terminal.  
nSave these instructions. Refer to them frequently  
and use them to instruct others who may use this  
tool. If you loan someone this tool, loan them these  
instructions also to prevent misuse of the product and  
possible injury.  
nKeep cord and charger from heat to prevent  
damage to housing or internal parts.  
nDo not let gasoline, oils, petroleum-based products,  
etc. come in contact with plastic parts. They contain  
chemicals that can damage, weaken, or destroy plastic.  
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.

power of the drill to tighten chuck jaws on drill bits. Chuck  
body could slip in your hand or your hand could slip and  
come in contact with rotating drill bit. This could cause  
an accident resulting in serious personal injury.

OPERATION  
WARNING:  
Battery tools are always in operating condition. There-  
fore, switch should always be locked when not in use or  
carrying at your side.  
DRILLING  
See Figure 10.  
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. However,  
the lower speed feature allows starting holes without center  
punching if desired. To accomplish this, simply operate the  
drill at lower speed until the hole is started.  
The material to be drilled should be secured in a vise or with  
clamps to keep it from turning as the drill bit rotates.  
Hold tool firmly and place the bit at the point to be drilled.  
Depress the switch trigger to start tool.  
Move the drill bit into the workpiece, applying only enough  
pressure to keep the bit cutting. Do not force or apply side  
pressure to elongate a hole.  
WARNING:  
Be prepared for binding at bit breakthrough. When these  
situations occur, the 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 you are not  
prepared, this loss of control can result in possible seri-  
ous injury.  
Fig. 10  
LEVEL  
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.  
If the bit jams in workpiece or if the drill stalls, release switch  
trigger immediately. Remove the bit from the workpiece and  
determine the reason for jamming.  
LEVEL DRILLING  
See Figure 11.  
Another convenient feature provided with the drill is a level.  
It is recessed in the motor housing on top of the drill. It  
can be used to keep drill bit level during horizontal drilling  
operations.

OPERATION  
ADJUSTABLE TORQUE CLUTCH  
See Figure 12.  
ADJUSTING  
RING  
TO DECREASE  
TORQUE  
When using the drill-driver for various driving applications,  
it becomes necessary to increase or decrease the torque  
in order to help prevent the possibility of damaging screw  
heads, threads, workpiece, etc. In general, torque should  
correspond to the intensity of the screw diameter. If the  
torque is too high or the screws too small, the screws may  
be damaged or broken.  
The torque is adjusted by rotating the torque adjustment  
ring. The torque is greater when the torque adjustment ring  
is set on a higher setting. The torque is less when the torque  
adjustment ring is set on a lower setting.  
The proper setting depends on the type of material and the  
size of screw you are using.  
ADJUSTING TORQUE  
nIdentify the twenty four torque indicator settings located

on the front of the drill.  
nRotate adjusting ring to the desired setting.
