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 (cordless) power tool.

WORK AREA SAFETY

• Keep the 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 that 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 the 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 the 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. The 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. The use of an RCD 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 masks, non-skid safety shoes, hard hats, 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 a power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or energizing 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.

Operation of Dewalt Hammer drill DCD776

Instructions for Use

• WARNING: Always observe the safety instructions and applicable regulations.

• WARNING: To reduce the risk of serious personal injury, turn tool off and disconnect battery pack before making any adjustments or removing/installing attachments or accessories. An accidental start-up can cause injury.

Proper Hand Position 

• WARNING: To reduce the risk of serious personal injury, ALWAYS use proper hand position as shown.

• WARNING: To reduce the risk of serious personal injury, ALWAYS hold securely in anticipation of a sudden reaction.

Proper hand position requires one hand on the top of the drill as shown, with the other hand on the main handle (i).

Screwdriver Operation

1.  Select the desired speed/torque range using the dual range gear selector to match the speed and torque of the planned operation.

2. Turn the torque adjustment collar (c) to the desired position. Lower numbers indicate lower torque settings; higher numbers indicate higher torque settings.

3. Insert the desired fastener accessory into the chuck as you would any drill bit.

4. Make some practice runs in scrap or on unseen areas to determine the proper position of the clutch collar.

5. Always start with lower torque settings, then advance to higher torque settings to avoid damage to the workpiece or fastener.

Drill Operation

• WARNING: To reduce the risk of serious personal injury, turn the tool off and disconnect the tool from the power source before making any adjustments or removing/installing attachments or accessories.

• WARNING: To reduce the risk of personal injury, ALWAYS ensure the workpiece is anchored or clamped firmly. If drilling thin material, use a wood “backup” block to prevent damage to the material.

1. Turn the collar (c) to the drill symbol.

2. Select the desired speed/torque range using the gear shifter to match the speed and torque to the planned operation.

3. For WOOD, use twist bits, spade bits, power auger bits or hole saws. For METAL, use high-speed steel twist drill bits or hole saws. Use a cutting lubricant when drilling metals. The exceptions are cast iron and brass which should be drilled dry.

4. Always apply pressure in a straight line with the bit. Use enough pressure to keep the drill biting, but do not push hard enough to stall the motor or deflect the bit.

5. Hold the tool firmly with both hands to control the twisting action of the drill. If the model is not equipped with a side handle, grip drill with one hand on the handle and one hand on the battery pack.
   CAUTION: Drill may stall if overloaded causing a sudden twist. Always expect the stall. Grip the drill firmly to control the twisting action and avoid injury.

6. IF DRILL STALLS, it is usually because
   it is being overloaded or improperly used. RELEASE the TRIGGER IMMEDIATELY, remove the drill bit from work, and determine the cause of the 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 the 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.

Hammer drill Operation 

1. Turn the collar (c) to the hammerdrill symbol.

2. Select the high-speed setting by sliding the selector back (away from the chuck).
   IMPORTANT: Use carbide-tipped or masonry bits only.

3. Drill with just enough force on the hammer to keep it from bouncing excessively or “rising” off the bit. Too much force will cause slower drilling speeds, overheating and lower drilling rates.

4. Drill straight, keeping the bit at a right angle to the work. Do not exert side pressure on the bit when drilling as this will cause clogging of the bit flutes and a slower drilling speed.

5. When drilling deep holes, if the hammer speed starts to drop off, pull the bit partially out of the hole with the tool still running to help clear debris from the hole.

NOTE: A smooth, even flow of dust from the hole indicates proper drilling rate.

Cleaning

• WARNING: Blow dirt and dust out of the main housing with dry air as often as dirt is seen collecting in and around the air vents. Wear approved eye protection and an approved dust mask when performing this procedure.

• WARNING: Never use solvents or other harsh chemicals for cleaning the non-metallic parts of the tool. These chemicals may weaken the materials used in these parts. Use a cloth dampened only with water and mild soap. Never let any liquid get inside the tool; never immerse any part of the tool into a liquid.
