Important Safety Instructions for All Tools

WARNING: When using electric tools, basic safety precautions should always be followed

to reduce risk of fire, electric shock, and personal injury, including the following:

SAVE THESE INSTRUCTIONS

WORK AREA

•Keep your work area clean and well lit. Cluttered benches and dark areas invite accidents.

•Do not operate power tools in explosive atmospheres, such as in the presence of flam-

mable liquids, gases, or dust. Power tools create sparks which may ignite the dust or fumes.

•Keep bystanders, children, and visitors away while operating a power tool. Distractions can

cause you to lose control.

ELECTRICAL SAFETY

•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.

•Avoid body contact with grounded surfaces such as pipes, radiators, ranges and refriger-

ators. There is an increased risk of electric shock if your body is grounded.

•Don’t 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 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.

•

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.

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,

•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. Air vents cover moving parts and should be avoided as well.

•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.

•Remove 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.

•Do not overreach. Keep proper footing and balance at all times. Proper footing and balance

enables better control of the tool in unexpected situations.

•Use safety equipment. Always wear eye protection. Dust mask, non-skid safety shoes, hard

hat, or hearing protection must be used for appropriate conditions.

TOOL USE AND CARE

• 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.

•

Do not force tool. Use the correct tool for your application. The correct tool will do the job bet-

ter and safer at the rate for which it is designed.

•

Do not use tool if switch does not turn it on or off. Any tool that cannot be controlled with the

switch is dangerous and must be repaired.

•

Disconnect the plug 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.

•

Store idle tools out of reach of children and other untrained persons. Tools are dangerous

in the hands of untrained users.

•

Maintain 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.

•

Check for misalignment or binding of moving parts, breakage of parts, and any other con-

dition that may affect the tools operation. If damaged, have the tool serviced before using.

Many accidents are caused by poorly maintained tools.

•

Use only accessories that are recommended by the manufacturer for your model.

Accessories that may be suitable for one tool, may become hazardous when used on another

tool.

SERVICE

•

Tool service must be performed only by qualified repair personnel. Service or maintenance

performed by unqualified personnel could result in a risk of injury.

•

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 Specific Safety Rules for Rotary Hammers

•

Hold tool 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.

•

Wear ear protectors when hammering for an extended period of time. Temporary hearing

loss or serious ear drum damage may result from high sound levels generated by hammer

drilling.

•

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 this tool without holding it with both hands.

• Hammer bits and tools get hot during operation.

Wear gloves when touching them.

CAUTION: DO NOT TOUCH ANY METAL PARTS OF THE TOOL when drilling or driving into

walls, floors or wherever live electrical wires may be encountered! Hold the tool only by insulat-

ed grasping surfaces to prevent electric shock if you drill or drive into a live wire.

WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other con-

struction activities contains chemicals known to cause cancer, birth defects or other reproduc-

tive 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 (CCA).

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.

• The label on your tool may include the following symbols.

V ..................volts A ....................amperes

Hz ................hertz W ....................watts

min................minutes ..................alternating current

..............direct current no....................no load speed

.................. Class II Construction .................... earthing terminal

..................safety alert symbol .../min revolutions per minute..............

Side Handle (Fig. 1)

CAUTION: Always use side handle (A) and hold rotary hammer with both hands.. It clamps

to the front of the gear case as shown and can be rotated 360˚ to permit right or left hand use.

The grip may be unscrewed and retightened to relocate the handle in the desired location.

Switch (Fig. 1)

The variable speed trigger switch (B) permits speed control. The farther the trigger switch is de-

pressed, the higher the speed of the rotary hammer.

NOTE: Use lower speeds for starting holes without a center punch, drilling in metal, plastics or

ceramics, or driving screws. Higher speeds are better for drilling in wood and composition board

and for using abrasive and polishing accessories.

Hammer/Drill Selector (Fig. 2)

To switch the tool from the drilling mode to another, rotate the dial (C) onto the applicable symbol.

There are three operational modes on the; rotation only drilling, rotary hammer and hammering

only, (chiseling).

This tool has the ability to rotate the chisel head to align with the work surface. Rotate the dial to

the appropriate symbol and turn the chisel to the desired position. Rotate the dial to the hammer

only mode to use the tool for chipping.

NOTE: The selector must be in either drill, rotary hammer, or hammer only mode at all times.

There are no operable modes in between.

Operation

DRILLING

1. Always unplug the drill when attaching or changing bits or accessories.

2. Always use sharp drill bits. For WOOD, use twist drill bits, spade bits, power auger bits, or hole

saws. For METAL, use steel twist drill bits or hole saws. For MASONRY, such as brick, cement,

cinder block, etc., use carbide-tipped bits rated for percussion drilling.

3. Be sure the material to be drilled is anchored or clamped firmly. If drilling thin material, use a

wood “back-up” block to prevent damage to the material.

4. Always apply pressure in a straight line with the bit. Use enough pressure to keep drill biting,

but do not push hard enough to stall the motor or deflect the bit.

5. Hold tool firmly to control the twisting action of the drill.

6. IF DRILL STALLS, it is usually because it is being overloaded or improperly used. RELEASE

TRIGGER IMMEDIATELY, remove drill bit from work, and determine cause of stalling. DO

NOT CLICK TRIGGER ON AND OFF IN AN ATTEMPT TO START A STALLED DRILL —

THIS CAN DAMAGE THE DRILL.

7. To minimize stalling or breaking through the material, reduce pressure on drill and ease the bit

through the last fractional part of the hole.

8. Keep the motor running when pulling the bit back out of a drilled hole. This will help prevent

jamming.

9. With variable speed drills there is no need to center punch the point to be drilled. Use a slow

speed to start the hole and accelerate by squeezing the trigger harder when the hole is deep

enough to drill without the bit skipping out.

DRILLING IN METAL

Start drilling with slow speed and increase to full power while applying firm pressure on the tool. A

smooth even flow of metal chips indicates the proper drilling rate. Use a cutting lubricant when

drilling metals. The exceptions are cast iron and brass which should be drilled dry. The cutting

lubricants that work best are sulphurized cutting oil or lard oil; bacon-grease will also serve the

purpose.

NOTE: Large (5/16” to 1/2”)

(7,6 mm to 13 mm)

holes in steel can be made easier if a pilot hole

(5/32” to 3/16”)

(3,8 mm to 5 mm)

is drilled first.

DRILLING IN WOOD

Start drilling with slow speed and increase to full power while applying firm pressure on the tool.

Holes in wood can be made with the same twist drills used for metal. These bits may overheat

unless pulled out frequently to clear chips from the flutes. For larger holes, use spade bits, power

auger bits, or hole saws. Work that is apt to splinter should be backed up with a block of wood.
