SAFETY INSTRUCTIONS
WARNING! Read and understand all instructions. Failure to follow all instructions listed below, may result in electric shock, fire and/or serious personal injury.
SAVE THESE INSTRUCTIONS
1. WORK AREA a) Keep your work area clean and well lit. Cluttered benches and dark areas invite ac-
cidents.
b) Do not operate power tools in explosive atmospheres, such as in the presence
of flammable liquids, gases or dusts. Power tools create sparks which may ignite the
dust or fumes.
c) Keep by-standers, children, and visitors away while operating a power tool. Dis-
tractions can cause you to lose control.
2. ELECTRICAL SAFETY a) 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. Before plugging in the tool, be certain the outlet voltage supplied is within the voltage marked on the nameplate. Do not use “AC only” rated tools with a DC power supply.
b) 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. If op-
erating the power tool in damp locations is unavoidable, a Ground Fault Circuit Interrupter must be used to supply the power to your tool. Electrician’s rubber gloves and footwear will further enhance your personal safety.
c) Don’t expose power tools to rain or wet conditions. Water entering a power tool will
increase the risk of electric shock.
d) Do not abuse the cord. Never use the cord to carry the tools or pull the plug
from an outlet. Keep cord away from heat, oil, sharp edges or moving parts. Re­place damaged cords immediately. Damaged cords increase the risk of electric shock.
e) When operating a power tool outside, use an outdoor extension cord marked
“W-A” or “W”. These cords are rated for outdoor use and reduce the risk of electric
shock. Refer to the “Recommended sizes of Extension Cords” in the Accessory section of this manual.
f) 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 tool should electrically malfunction or break down, grounding provides a low resistance path to carry electricity away from the user.
3. PERSONAL SAFETY a) 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 seri-
ous personal injury.

b) 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. Keep handles dry, clean and free from oil and grease. Rubber gloves and non-skid footwear are recommended when working outdoors.
c) Avoid accidental starting. Be sure switch is “OFF” before plugging in. Carrying
tools with your finger on the switch or plugging in tools that have the switch “ON” invites accidents. Do not use a tool if the power switch does not turn it “ON” and “OFF”.
d) Remove all adjusting keys and wrenches. Make a habit of checking that adjusting
keys, wrenches, etc. are removed from the tool before turning it “ON”.
e) Do not overreach. Keep proper footing and balance at all times. Proper footing and
balance enable better control of the tool in unexpected situations.
f) Use safety equipment. Always wear eye protection. Dust mask, non-skid safety
shoes, hard hat, or hearing protection may be used for appropriate conditions.
g) Keep hands away from all cutting edges and moving parts. h) 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.
4. TOOL USE AND CARE a) Use clamps or other practical way to secure and support the work-piece to a
stable platform. Holding the work by hand or against your body is unstable and may lead
to loss of control.
b) Do 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. Excessive force only causes operator fatigue, increased wear and reduced control.
c) Do 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.
d) Disconnect the tool from the power source before making any adjustments,
changing accessories, or storing the tool. Such preventative safety measures reduce
the risk of starting the tool accidentally.
e) Store idle tools out of reach of children and other untrained persons. Tools are
dangerous in the hands of untrained users.
f) Maintain tools with care. Keep cutting tools sharp and clean. Properly maintained
tools, with sharp cutting edges, are less likely to bind and easier to control.
g) 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.
h) Use only accessories that are recommended by the manufacturer for your mod-
el. Accessories that may be suitable for one tool may create a risk of injury when used on
another tool.
i) Use the right tool. Do not force the tool or attachment to do a job for which it was not
designed.
5. SERVICE a) Tool service must be performed only by qualified repair personnel. Service or
maintenance performed by unqualified personnel could result in a risk of injury.
b) When servicing a 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 electric shock or injury.

ADDITIONAL SAFETY RULES - FOR DRILLS
WARNING! Failure to follow these rules may result in serious personal injury.
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.
2) Always wear ear protectors with impact drill. Exposure to noise can cause hearing loss.
3) Always wear eye protectors when using tool. Use a dust mask or respirator for ap­plications which generate dust.
4) Always use the auxiliary handle supplied with the tool. Keep a firm grip on the tool at
all times. Do not attempt to operate this tool without holding it with both hands.
5) Always check walls and ceiling to avoid hidden power cables and pipes.
6) Do not start the drill with the chuck key in the chuck.
7) Make sure the power switch is not “ON” before you plug the tool in. Accidental start-
ups could cause injury.
8) Make sure drill bits are tightened securely in the chuck.
9) Do not use damaged or worn drill bits. Dull or damaged bits have a greater tendency to
bind in the work-piece.
10) Use clamps or a vise to hold work-piece whenever possible.
11) Secure material before cutting. Never hold it in your hand or across your legs.
12) Save these instructions. Refer to them frequently and use them to instruct others who may
use this tool. If someone borrows this tool, make sure they have these instructions.
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 paint
• Crystalline silica from bricks and cement and other masonry products
• Arsenic and chromium from chemically-treated lumber
Your risk to 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
• Work with approved safety equipment, such as those dust masks that are specifically designed
to filter out microscopic particles.

We recommend that you purchase your accessories from the same store that sold you the tool. Use good quality accessories marked with a well-known brand name. Choose the type according to the work you intend to undertake. Refer to the accessory packaging for further details. Store personnel can assist you and offer advice.
EXTENSION CORDS
Warning: Use proper extension cords. Make sure your extension cord is in good condi-
tion and is a 3-wire extension cord which has a 3-prong grounding type plug and matching receptacle which will accept the machine’s plug. When using an extension cord, de sure to use one heavy enough to carry the current of the machine. An undersized cord will cause a drop in line voltage, resulting in loss of power and overheating. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.

8. CHUCK ADJUSTMENT
To open the chuck jaws, rotate the front section of the chuck counter-clockwise. Once the chuck jaws open to the desired position, insert the bit, then rotate the chuck clockwise until the bit fits the chuck. Ensure that the drill/ driver bit is in the centre of the chuck jaws. Aligning the teeth, insert the chuck key into the hole at the front sec­tion of the chuck and turn to tighten. Finally, using the chuck key, firmly rotate the two separate chuck sections in opposite directions until your drill/driver bit is secured firmly in the chuck. To remove bit, loosen the chuck jaws with the chuck key and repeat the aforementioned steps (See Fig 6).
Warning: Before installing accessory, re-
move plug from power supply. Do not at­tempt to tighten drill bits (or any other accessory) by gripping the front part of the chuck and turning the tool on. Damage to the chuck and personal injury may result.
9. ADJUSTABLE DEPTH GAUGE
Fit the drill bit or driver bit into the chuck. Loosen the depth gauge by rotating the handle counter-clockwise. Slide the depth gauge until the distance between the depth gauge end and the drill/driver bit end is equal to the depth of hole/screw you wish to make. Then clamp the depth gauge by rotating the handle clockwise.
WORKING HINTS FOR YOUR DRILL
If your power tool becomes too hot, set the speed to maximum and run no load for 2-3 minutes to cool the motor. Tungsten carbide drill bits should always be used for concrete and masonry. When drilling in metal, only use HSS, Titanium or Cobalt drill bits that are in good condition. Always use a magnetic bit holder when using short screwdriver bits. Where possible use a pilot hole before drilling a large diameter hole in metal material.
MAINTAIN TOOLS WITH CARE
Keep tools sharp and clean for better and safer perfor­mance. Follow instructions for lubricating and changing accessories. Inspect tool cords periodically and if dam­aged, have repaired by authorized service facility.
