Manual

English

this tool without holding it with both hands. Operating this

tool with one hand will result in loss of control. Breaking through or

encountering hard materials such as re-bar may be hazardous as

well.

• Accessories and tool may get hot during operation.

Wear gloves when handling them if performing heat producing

applications such as hammerdrilling and drilling metals.

• Do not operate this tool for long periods of time. Vibration

caused by hammer action may be harmful to your hands and arms.

Use gloves to provide extra cushion and limit exposure by taking

frequent rest periods.

• Air vents often cover moving parts and should be avoided.

Loose clothes, jewelry or long hair can be caught in moving parts.

WARNING: ALWAYS use safety glasses. Everyday eyeglasses are

NOT safety glasses. Also use face or dust mask if cutting operation is

dusty. ALWAYS WEAR CERTIFIED SAFETY EQUIPMENT:

• ANSI Z87.1 eye protection (CAN/CSA Z94.3),

• ANSI S12.6 (S3.19) hearing protection,

• NIOSH/OSHA/MSHA respiratory protection.

WARNING: Some dust created by power sanding, sawing,

grinding, drilling, and other construction activities contains chemicals

known to the State of California 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.

c) 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.

d) 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.

6) SERVICE

a) 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.

Drill/Driver/Hammerdrill Safety Warnings

• Wear ear protectors when impact drilling. Exposure to noise

can cause hearing loss.

• Use auxiliary handle(s), if supplied with the tool. Loss of

control can cause personal injury.

• Hold power tool by insulated gripping surfaces, when

performing an operation where the cutting accessory may

contact hidden wiring. Cutting accessory contacting a “live” wire

may make exposed metal parts of the power tool “live” and could

give the operator an electric shock.

• Use clamps or other practical way 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.

• Wear safety goggles or other eye protection. Hammering and

drilling operations cause chips to fly. Flying particles can cause

permanent eye damage.

• Always use the side handle supplied with the tool. Keep a

firm grip on the tool at all times. Do not attempt to operate

I keep stripping the screw head when using the drill-driver. Why is that? Verified

Most drill-drivers can be set to screw harder or softer. If the head keeps being stripped, the drill-driver should probably be put into a different setting. When it is a wireless device, always be sure the battery is charged for an optimal result.

Do I need to wear hearing protection when using a drill? Verified

Can I store power tools in a shed or garage? Verified

In general, you can store power tools in a shed or garage, even if it sometimes freezes there. However, it is better for the lifespan of the power tool to store it in a dry place without major temperature fluctuations. In a shed or garage, differences in temperature can cause condensation to form, which can cause rust. In addition, tools that run on batteries last shorter and do not charge as well at very low temperatures. To be sure how your power tool needs to be stored, always thoroughly read the user manual.
