SAVE THESE INSTRUCTIONS FOR REFERENCE

WARNING: Use hearing protection, particularly during extended periods of operation of the tool, or if the operation is noisy.

GENERAL SAFETY WARNINGS

WARNING: Before using this tool or any of its accessories, read this

manual and follow all Safety Rules and Operating Instructions. The important precautions, safeguards and instructions appearing in this manual are not meant to cover all possible situations. It must be understood that common sense and caution are factors which cannot be built into the product.

Page 4

ELECTRICAL SAFETY

WARNING: To avoid electrical hazards, fire hazards or damage to the

tool, use proper circuit protection.

This tool is wired at the factory for 120 V AC operation. It must be connected to a 120 V AC, 15 A circuit that is protected by a time-delayed fuse or circuit breaker. To avoid shock or fire, replace power cord immediately if it is worn, cut or damaged in any way.

GENERAL SAFETY WARNINGS

WEAR A DUST MASK THAT IS DESIGNED TO BE USED WHEN OPERATING A POWER TOOL IN A DUSTY ENVIRONMENT.

WARNING: Dust that is created by power sanding, sawing, grinding,

drilling, and other construction activities may contain chemicals that are known to cause cancer, birth defects, or other genetic abnormalities. These chemicals include:

Lead from lead-based paints Crystalline silica from bricks, cement, and other masonry products Arsenic and chromium from chemically treated lumber

The level of risk from exposure to these chemicals varies, according to how often this type of work is performed. In order to reduce exposure to these chemicals, work in a well-ventilated area, and use approved safety equipment, such as a dust mask that is specifically designed to filter out microscopic particles.

Page 5

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.

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.

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 a ground fault circuit interrupter (GFCI) reduces 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 a power tool while you are 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 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.

POWER TOOL SAFETY

Page 6

PERSONAL SAFETY – cont’d

Do not overreach. Keep proper footing and balance at all times. This enables

better control of the power tool in unexpected situations.

Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewellery or long hair

can be caught in moving parts.

If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of

dust collection can reduce dust-related hazards.

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 making 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.

Hold power tool by insulated gripping surfaces, when performing an operation where the fastener may contact hidden wiring or its own cord. Fasteners

contacting a "live" wire may make exposed metal parts of the power tool "live" and could give the operator an electric shock.

Wear ear protectors. 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 tools by insulated gripping surfaces when performing an operation where the cutting tool may contact hidden wiring or its own cord. Cutting

accessory contacting a "live" wire may make exposed metal parts of the power tool "live" and could give the operator an electric shock.

POWER TOOL SAFETY

Page 7

Service 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.

WARNING: Know your rotary hammer. Do not plug the tool into the power source until you have read and understand this Instruction Manual.

Learn the tool’s applications and

limitations, as well as the specific potential hazards related to this tool.

Following this rule will reduce the risk of electric shock, fire, or serious injury.

Always wear eye protection. Any power tool can throw foreign objects into your eyes

and cause permanent eye damage. ALWAYS wear safety goggles (not glasses) that comply with ANSI safety standard Z87.1. Everyday glasses have only impact resistant lenses. They ARE NOT safety glasses.

WARNING: Glasses or goggles not in compliance with ANSI Z87.1 could cause serious injury when they break.

WARNING: Always use a safety shield, hearing protection and dust mask when operating the drill in "hammer" mode.

Use only hammer drill bits and accessories that are designed for use with a rotary hammer when using this rotary hammer in the hammer mode. Standard drill bits are NOT designed for use in a rotary hammer and MUST NOT be used with a rotary hammer. They may shatter and possibly cause serious injury.

Do not drill material too small to be securely held.

Always keep hands out of the path of the drill bit. Avoid awkward hand positions where a sudden slip could cause your hand to move into the path of the drill bit.

Secure the workpiece. Use clamps or a vice to hold the workpiece. It is safer than using your hand and it frees both hands to operate the tool.

Make sure there are no nails or foreign objects in the part of the workpiece to be drilled.

To avoid injury from accidental starting, always remove the plug from the power source before installing or removing a drill bit.

Do not install or use any drill bit that

exceeds 7” (17.5 cm) in length or extends

more than 6” (15 cm) beyond the chuck

jaws. They can bend or break suddenly.

RULES

SAVE THESE INSTRUCTIONS FOR REFERENCE

POWER TOOL SAFETY

Page 8

Before starting the operation, jog the drill switch to make sure the drill bit does not wobble or vibrate.

Do not use fly cutters or multiple-part hole cutters, because they can come apart or become unbalanced during use.

Make sure the spindle has come to a complete stop before touching the chuck or attempting to change the drill bit.

When using the chuck, always make sure the chuck spindle is properly inserted into the tool and the drill bit firmly tightened in the chuck before starting the tool.

When using a drill bit or screwdriver bit adaptor in the tool, make sure it is properly inserted into the tool before starting the tool.

WARNING: Keep the extension cord clear of the working area. Position

the cord so it will not get caught on the workpiece, tools or any other obstructions while you are working with the power tool.

Make sure any extension cord used with this tool is in good condition. When using an extension cord, be sure to use one of heavy enough gauge to carry the current the tool will draw. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating.

The table below shows the correct size to use according to cord length and nameplate ampere rating. If in doubt, use the next heavier gauge. The smaller the gauge number the heavier the cord.

Be sure your extension cord is properly wired and in good condition. Always replace a damaged extension cord or have it repaired by a qualified electrician before using it. Protect your extension cord from sharp objects, excessive heat and damp or wet areas.

Use a separate electrical circuit for your power tools. This circuit must not be less than 14 gauge wire and should be protected with either a 15 AMP time delayed fuse or circuit breaker. Before connecting the power tool to the power source, make sure the switch is in the OFF position and the power source is the same as indicated on the nameplate. Running at lower voltage will damage the motor.

DRILLING

When drilling in smooth hard surfaces such as metal, 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.

NOTES: a) Use slower drilling speeds when drilling larger holes. b) Use a masonry bit when operating the rotary hammer in hammer mode ONLY when drilling in concrete.

ASSEMBLY AND OPERATING

For safety reasons, the operator must

read the sections of this Owner’s

Manual entitled "GENERAL SAFETY WARNINGS", "POWER TOOL SAFETY", "SPECIFIC SAFETY RULES", "EXTENSION CORD SAFETY" and "SYMBOLS" before using this rotary hammer.

Verify the following every time the rotary hammer is used:

1. Safety glasses, safety goggles, or face shield is being worn.

2. Hearing protection is being worn.

3. The chuck, drill bit and accessories are properly installed.

4. The bit is in good condition and is properly tightened into the SDSplus® clamp or chuck.

Failure to observe these safety rules will significantly increase the risk of injury.

WARNING

Page 18

DRILLING – cont’d

The workpiece to be drilled should be secured in a vice or with clamps to keep it from turning as the drill bit rotates (Fig. 8).

1. Check drill bit to make sure it is firmly locked into the SDS clamp or drill chuck and the forward / reverse switch is in the forward position.

2. Hold the tool firmly with both hands whenever possible. Use one hand to grasp the handle and switch and the other to grasp the body of the tool.

NOTE: Make sure the hand placed on the body of the tool does not cover the air vents. Covering these air vents will reduce the motor cooling and possibly lead to overheating the motor.

3. While holding the tool firmly, place the point of the drill bit at the point to be drilled. Depress the switch trigger to start the drill.

4. Move the drill bit into the workpiece applying only enough pressure to keep the bit cutting. Do not force the drill bit or apply sideways pressure to elongate the hole.

WARNING: Be prepared for

binding and bit breakthrough. When these situations occur, the drill bit has the tendency to grab the workpiece. This action will kick the tool opposite to the direction of drill bit rotation and could cause loss of control when breaking through material as you complete drilling the hole. If you are not prepared, this loss of control can result in possible serious injury.

ASSEMBLY AND OPERATING

Fig. 8

Page 19

DRILLING – cont’d

When drilling metals, use a light oil on the drill bit to keep it from overheating. The oil will prolong the life of the drill bit and improve the drill cutting action. If the bit jams in the workpiece or if the tool stalls, release the trigger switch immediately. Remove the bit from the workpiece and determine the reason for jamming

DRILLING IN CONCRETE WARNING: Always use a face

shield when drilling in concrete.

Always use the hammer mode and slower drill speeds for faster drilling in concrete. Always use carbide tipped masonry bits.

WARNING: When servicing, use

only identical replacement parts. Use of any other part may create a hazard or cause product damage.

DO NOT use solvents when cleaning plastic parts. Plastics are susceptible to damage from various types of commercial solvents and may be damaged by their use. Use a clean cloth to remove dirt, dust, oil, grease etc.

WARNING: Do not at any time

allow brake fluids, gasoline, petroleumbased products, penetrating oils, etc. to come into contact with plastic parts. They contain chemicals that can damage, weaken or destroy plastic.

DO NOT abuse power tools. Abusive practices can damage the tool as well as the workpiece.

WARNING: DO NOT attempt to

modify tools or create accessories. Any such alteration or modification is misuse and could result in a hazardous condition leading to possible serious injury. It will also void the warranty.
