GENERAL POWER TOOL SAFETY WARNINGS

WARNING

Read all safety warnings and all 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 (cord-less) power tool.

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 ground fault circuit interrupter (GFCI) protected supply. Use of a 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.
  • 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 jewel-lery. 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.
  • Do not wear loose clothing or jewelry. Contain long hair. Loose clothes, jewelry, or long hair can be drawn into air vents.
  • Do not use on a ladder or unstable support. Stable footing on a solid surface enables better control of the power tool in unexpected situations.

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 bind-ing 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 main-tained 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.

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.
  • When servicing a power tool, use only identical replacement parts. Follow instructions in the Main-tenance section of this manual. Use of unauthorized parts or failure to follow Maintenance instructions may create a risk of shock or injury.

HAMMER DRILL SAFETY WARNINGS

  • Wear ear protectors with 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 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.
  • Know your power tool. Read operator’s manual care-fully. Learn its 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 with side shields marked to comply with ANSI Z87.1. Following this rule will reduce the risk of serious personal injury.
  • Protect your lungs. Wear a face or dust mask if the operation is dusty. Following this rule will reduce the risk of serious personal injury.
  • Protect your hearing. Wear hearing protection during extended periods of operation. Following this rule will reduce the risk of serious personal injury.
  • Inspect tool cords periodically and, if damaged, have repaired at your nearest authorized service center. Constantly stay aware of cord location. Following this rule will reduce the risk of electric shock or fire.
  • Check damaged parts. Before further use of the tool, a guard or other part that is damaged should be carefully checked to determine that it will operate properly and perform its intended function. Check for alignment of moving parts, binding of moving parts, breakage of parts, mounting, and any other conditions that may affect its operation. A guard or other part that is damaged should be properly repaired or replaced by an authorized service center. Following this rule will reduce the risk of shock, fire, or serious injury.
  • Make sure your extension cord is in good condition. When using an extension cord, be sure to use one heavy enough to carry the current your product will draw. A wire gauge size (A.W.G.) of at least 14 is recommended for an extension cord 50 feet or less in length. A cord exceeding 100 feet is not recom-mended. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating.
  • Inspect for and remove all nails from lumber before using this tool. Following this rule will reduce the risk of serious personal injury.
  • If the power supply cord is damaged, it must be replaced only by the manufacturer or by an authorized service center to avoid risk.
  • Save these instructions. Refer to them frequently and use them to instruct others who may use this product. If you loan someone this product, loan them these instruc-tions also.

ELECTRICAL

DOUBLE INSULATION
Double insulation is a concept in safety in electric power tools, which eliminates the need for the usual three-wire grounded power cord. All exposed metal parts are isolated from the internal metal motor components with protect-ing insulation. Double insulated tools do not need to be grounded.

WARNING:
The double insulated system is intended to protect the user from shock resulting from a break in the product’s internal insulation. Observe all normal safety precautions to avoid electrical shock.

NOTE: Servicing of a product with double insulation requires extreme care and knowledge of the system and should be performed only by a qualified service technician. For service, we suggest you return the product to your nearest authorized service center for repair. Always use original factory replacement parts when servicing.

ELECTRICAL CONNECTION
This product has a precision-built electric motor. It should be connected to a power supply that is 120 volts, AC only (normal household current), 60 Hz. Do not operate this product on direct current (DC). A substantial voltage drop will cause a loss of power and the motor will overheat. If the product does not operate when plugged into an out-let, double-check the power supply.

EXTENSION CORDS
When using a power tool at a considerable distance from a power source, be sure to use an extension cord that has the capacity to handle the current the tool will draw. An undersized cord will cause a drop in line voltage, resulting in overheating and loss of power. Use the chart to deter-mine the minimum wire size required in an extension cord. Only round jacketed cords listed by Underwriter’s Labora-tories (UL) should be used.
When working outdoors with a product, use an extension cord that is designed for outside use. This type of cord is designated with “W-A” or “W” on the cord’s jacket.
Before using any extension cord, inspect it for loose or exposed wires and cut or worn insulation.

  • Loosen the handle assembly by turning the handle coun-terclockwise.

  • Slide the auxiliary handle assembly onto the hammer drill in the desired operating position.
    NOTE: Make sure the notches on the inside of the auxiliary handle engage the tabs on the drill housing.

  • Securely tighten by turning the auxiliary handle clockwise.
    NOTE: Be sure the auxiliary handle is securely tightened against the depth stop rod clamp. This secures the depth stop rod at the desired depth of cut. It also secures the auxiliary handle.

INSTALLING THE CHUCK KEY STRAP
See Figure 2, page 11.
Use the chuck key strap to store the chuck key when not in use.
To install:

  • Form a loop by forcing the end of the strap with the round holes through the slot on the opposite end.
  • Place the loop over the cord and pull it tight.
  • Mount the chuck key by inserting the geared end through the hole in the holder. Large keys fit in the larger hole; smaller keys fit in the small hole.

If the lock-on feature is engaged during use and the drill becomes disconnected from the power supply, disengage the lock-on feature immediately.

WARNING:

Before connecting the drill to a power supply source, always check to be sure it is not in lock-on position (de-press and release the switch trigger). Failure to ensure that it is not locked-on could result in accidental starting of the drill resulting in possible serious injury. Do not lock the switch trigger in applications where the drill may need to be suddenly stopped.

DIRECTION OF ROTATION SELECTOR (FORWARD/REVERSE)
See Figure 4, page 12.
The direction of bit rotation is reversible and is controlled by a selector located above the switch trigger. With the drill held in normal operating position, the direction of rotation selector should be positioned to the left of the switch trig-ger for forward drilling. The drilling direction is reversed when the selector is to the right of the switch trigger.

NOTICE:
To prevent gear damage, always allow the chuck to come to a complete stop before changing the direction of rotation.
To stop the drill, release the switch trigger and allow the chuck to come to a complete stop.

NOTE: The drill will not run unless the direction of rotation selector is pushed fully to the left or right.
Avoid running the drill at low speeds for extended periods of time. Running at low speeds under constant usage may cause the drill to become overheated. If this occurs, cool the drill by running it without a load and at full speed.

OPERATION

TO INSTALL BITS
See Figures 5 – 6, page 12.

  •  Unplug the drill.

  • Insert the chuck key and twist counterclockwise.

  • Open or close the chuck jaws to a point where the open-ing is slightly larger than the bit size you intend to use. Also, raise the front of the drill slightly to keep the bit from falling out of the chuck jaws.

  • Insert the drill bit.
    WARNING:
    Make sure to insert the drill bit straight into the chuck jaws. Do not insert the drill bit into the chuck jaws at an angle then tighten, as shown in figure 7. This could cause the drill bit to be thrown from the drill, resulting in possible serious personal injury or damage to the chuck.

  • Tighten the chuck jaws securely on the drill bit, using the chuck key provided.

  • Remove the chuck key.

TO REMOVE BITS
See Figure 5, page 12.

  • Unplug the drill.
  • Loosen the chuck jaws using the chuck key provided.
  • Remove the drill bit.
  • Remove the chuck key.

USING THE AUXILIARY HANDLE ASSEMBLY

To adjust the auxiliary handle assembly,

  • Loosen the handle assembly by turning the handle coun-terclockwise.
  • Rotate the auxiliary handle assembly to the desired oper-ating position.
  • Securely tighten by turning the auxiliary handle clockwise.

Be sure the auxiliary handle is securely tightened against the depth stop clamp. This secures the depth stop rod at the desired depth of cut. It also secures the auxiliary han-dle.
NOTE: For convenience and ease of starting threads, the hex nut has been trapped inside the molded slot in the aux-iliary handle.
The depth stop rod helps control the depth of drilled holes.
NOTE: When properly installed, the teeth on the depth stop rod should be aligned with the teeth indicator on the depth stop clamp.

Adjust the depth stop rod so that the drill bit extends beyond the end of the rod to the required drilling depth.
When drilling holes with the depth stop rod installed, the desired hole depth has been reached when the end of the rod comes in contact with the surface of the workpiece.
SELECTING HAMMER MODE OR DRILLING MODE
See Figure 8, page 12.
To adjust for type of drilling, slide the selector on top of the motor housing to hammer mode or drilling mode. The ham-mer mode symbol is on the right and the drill bit symbol is on the left.
NOTE :
The hammer drill has not been designed for reverse hammering.
Use carbide-tipped bits and select hammer mode when drilling in hard materials such as brick, tile, concrete, etc.
Select normal drill mode when drilling with twist drills, hole saws, etc., in soft materials.

DRILLING/DRIVING SCREWS

  • Depress and release the switch trigger to be sure the drill is in the OFF position before connecting it to a power supply.
  • Check the direction of rotation selector for the correct.)esrever ro drawrof( gnittes
  • Secure the material to be drilled in a vise or with clamps.setator tib llird eht sa input morf ti peek ot
  • Plug the drill into power supply.
  • Hold the drill firmly and place the bit at the point to be drilled, or where the screw is to be driven.

WARNING :

Do not drive a screw where there is likely to be hidden wiring behind the surface. Contact with a “live” wire will make exposed metal parts of the tool “live” and possibly shock the operator. If you must drive a screw where hid- den wire may be present, always hold tool by insulated gripping surfaces (handle) when performing the operation to prevent a shock to the operator.

  • Depress the switch trigger to start the drill.
  • Move the drill bit into the workpiece, applying only enough pressure to keep the bit cutting or driving the screw. Do not force the drill or apply side pressure to elongate a hole. Let the tool do the work.n

WARNING:

When drilling, be prepared for binding at bit breakthrough. When these situations occur, the drill has a tendency to grab and kick in the opposite direction and could cause loss of control when breaking through material. If not prepared, this loss of control can result in possible seri-ous injury.

  • 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.
  • If the bit jams in the workpiece or if the drill stalls, stop the tool immediately. Remove the bit from the workpiece and determine the reason for jamming.

WOOD AND METAL DRILLING
For maximum performance, use high speed steel bits for wood or metal .gnillirdSelect drilling mode. Begin drilling at a very low speed to prevent the bit from slipping off the starting point.

Wood Drilling

  • Increase the speed as the drill bit bites into the .lairetam
  • When drilling through holes, place a block of wood behind the workpiece to prevent ragged or splintered edges on.eloh eht fo edis kcab eht

Metal and Steel Drilling

  • Use a light oil on the drill bit to keep it from overheating. The oil will prolong the life of the bit and increase the drilling action.
  • Maintain a speed and pressure which allows cutting without overheating the bit. Applying too much pressure will:
    • Overheat the drill;
    • Wear the bearings;
    • Bend or burn bits; and
