SAFETY INSTRUCTIONS
GENRAL SAFETY RULES
WARNING: Read all safety warnings and 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.
1) 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.
2) ELECTRICAL SAFETY
√
√√
√ 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.
√
√√
√ 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 a power tool in a damp location is unavoidable, use a residual current device (RCD)
protected supply. Use of an RCD reduces the risk of electric shock.
3) PERSONAL SAFETY
√
√√
√ Stay 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.

√
√√
√ 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 switch is in the off-position before connecting to power
source and / or battery pack, picking up or carrying the tool. Carrying power tools with your finger on
the switch or energising in 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 control of the
power tool in unexpected situations.
√
√√

are connected and properly used. Use of these devices can reduce dust-related hazards.
4) POWER TOOL USE AND CARE
√
√√
√ 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
marking 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.
√
√√
√ 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.
5) BATTERY TOOL USE AND CARE
√
√√
√ Recharge only with the charger specified by the manufacturer. A charger that 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 specifically 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 metal objects that can make 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.

SPECIFIC SAFETY RULES FOR RIGHT ANGLE DRILL
√
√√
√ Use battery only with charger listed.
Battery pack Charger
252-8016 252-8020
√
√√
√ Hold power tools by the insulated gripping surfaces when performing an operation where the tool
may contact hidden wiring or its own cord. Contact with a “live” wire will also make exposed metal parts
of the tool “live” and shock the operator.
√
√√
√ Use clamps or another practical way to secure and support the workpiece to a stable platform
before drilling. Holding the work by hand against your body leaves it unstable and may lead to loss of
control.
√
√√
√ Always hold the tool with both hands. If the bit jams two hands will give you maximum control over
torque reaction or kickback.
√
√√
√ Use protective gloves when removing the bit from the tool, or first allow the clamp to cool down. The bit
may be hot after prolonged use.
√
√√
√ Use protective gloves when operating the tool. Protective gloves can help to keep you from being
burnt and hurt.

√
√√
√ Keep your hands away from the motor-housing vents. Hot gas comes from the vents during operation.
√
√√
√ If the bit becomes bound in the workpiece, release the trigger immediately, reverse the direction of
rotation and slowly squeeze the trigger to back out the bit. Be ready for a strong reaction torque. The
drill body will tend to twist in the opposite direction as the drill bit is rotating.
√
√√
√ Release the trigger immediately when the screws are tightened to avoid breaking the screw.
√
√√
√ For best results, your battery tool should be charged in a location where the temperature is more that
50°F(10°C) but less that 104°F(40°C). Do not store outside or in vehicles.

OPERATION
BATTERY PROTECTION
The battery circuitry protects the battery pack from extreme temperature, over discharge, and over-charge. To
protect the battery from damage and prolong its life, the battery pack circuitry will turn off the battery pack if it
becomes overloaded or if the temperature becomes too high during use. This may happen in extremely high
torque, binding, and stalling situations. The battery pack will begin normal operation when it cools down.
NOTE: A significantly reduced run time after fully charging the battery pack indicates that the battery is near
the end of its usable life and must be replaced.
COLD WEATHER OPERATION

When the battery pack is very cold, it may “pulse” for the first minute of use to warm itself. Put the battery pack
on a tool and use the tool in a light application. After about a minute, the battery pack will have warmed itself
and will operate normally.
WHEN TO CHARGE THE BATTERY PACK
It is not necessary to run down the battery pack charge before recharging. The Lithium-Ion battery can be
charged at any time and will not develop a “memory” when charged after only a partial discharge.
Remove the battery pack from the tool when convenient for you and your job. “Top off” the battery pack
charge by charging it for a time before starting a big job or long period of use.
Due to Lithium-Ion fade-free properties, the only time it is necessary to charge the Lithium-Ion battery pack is
when the pack has reached the end of its charge. To signal the end of charge, power to the tool will drop
quickly. Charge the battery pack as needed.
HOW TO CHARGE THE BATTERY PACK
NOTE: This Lithium-Ion battery pack is shipped partially charged.
Before using it the first time, fully charge the battery pack.
A fully discharged battery pack will charge in about 30 minutes in
a surrounding temperature between 50°F (10°C) and 104°F
(40°C).
1. Charge the Lithium-Ion battery pack with the correct charger.
2. Connect the charger to a power supply.
3. Align the raised ribs of the battery pack with the slot in the
charger.
4. Insert the battery pack into the charger (Fig. 2).
5. The charger will communicate with the battery pack to evaluate
the condition of the battery pack.
6. The green light will flash while the battery pack is charging. After charging is complete, the green LED on
the charger will be on. The flickering red light indicates a defective battery or a bad connection between the
battery and the charger.
7. The battery pack will fully charge if left on the charger, but it will not overcharge.
NOTE: For your convenience, the charger can operate with most generators and inverters rated at 300 watts
or higher.
LED FUNCTIONS OF CHARGER (Fig. 3)

INSTALLING BITS (Fig. 7)
1. Lock the trigger switch by placing the direction of rotation
selector in the OFF (center) position.
2. With one hand, pull the sleeve toward the front of the tool,
and hold it in place.
3. With the other hand, insert the 1/4-in. bit into the hexagonal
chuck.
4. Release the sleeve and check that it returns to its original
position.
5. To remove an accessory, pull locking sleeve forward and simply remove it.
WARNING! If the sleeve does not return to its original position, the bit is not correctly installed. To avoid
loss of control, ensure bit is locked in chuck by pulling on bit after it has been inserted.
DRILLING
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.
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 the tool firmly and
place the bit at the point to be drilled. Depress the switch trigger to
start the 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.
Drilling wood
When drilling hole in wood, twist bits can be used. Twist bits may overheat unless pulled out frequently to clear
chips from flutes.
Use a “back-up” block of wood for work that is likely to splinter, such as thin materials.
You will drill a cleaner hole if you ease up on the pressure just before the bit breaks through the wood. Then
complete the hole from the back side.
Drilling metal
There are two rules for drilling hard materials. First, the harder the material, the greater the pressure you need
to apply to the tool. Second, the harder the material, the slower the speed you need to operate the tool.
Here are a couple of tips for drilling in metal:
Lubricate the tip of the bit occasionally with cutting oil except when drilling soft metals such as aluminum,
copper or cast iron.
If the hole to be drilled is fairly large, drill a smaller hole first, then enlarge to the required size, it’s often faster
in the long run.
Maintain enough pressure to assure that the bit does not just spin in the hole. This will dull the bit and greatly
shorten its life.
