SAFETY INSTRUCTIONS AND INSTRUCTION MANUAL

Read and understand all of the safety precautions, warnings and operating instructions in the Instruction Manual before operating or maintaining this power tool. Most accidents that result from power tool operation and maintenance are caused by the failure to observe basic safety rules or precautions. An accident can often be avoided by recognizing a potentially hazardous situation before it occurs, and by observing appropriate safety procedures. Basic safety precautions are outlined in the “SAFETY” section of this Instruction Manual and in the sections which contain the operation and maintenance instructions. Hazards that must be avoided to prevent bodily injury or machine damage are identified by WARNINGS on the power tool and in this Instruction Manual. NEVER use this power tool in a manner that has not been specifically recommended by HITACHI.

MEANINGS OF SIGNAL WORDS

WARNING indicates a potentially hazardous situations which, if ignored, could result in death or serious injury. CAUTION indicates a potentially hazardous situations which, if not avoided, may result in minor or moderate injury, or may cause machine damage. NOTE emphasizes essential information.English

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) Keep your work area clean and well lit. Cluttered benches and dark areas invite accidents. (2) 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 of fumes. (3) Keep bystanders children, and visitors away while operating a power tool. Distractions can cause you to lose control.

2. Electrical Safety

(1) 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. (2) 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. (3) Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock. (4) Do not abuse the cord. Never use the cord to carry the tools or pull the plug from a receptacle. Keep cord away from heat, oil, sharp edges or moving parts. Replace damaged cords immediately. Damaged cords increase the risk of electric shock. (5) 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.

(1) 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. (2) 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. (3) 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.English

(4) 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. (5) Do not overreach. Keep proper footing and balance at all times. Proper footing and balance enables better control of the tool in unexpected situations. (6) Use safety equipment. Always wear protective glasses. Dust mask, nonskid safety shoes, hard hat, or ear plugs must be used for appropriate conditions.

4. Tool Use and Care

(1) 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. (2) 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. (3) 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. (4) Disconnect the plug form the power source before making any adjustments, changing accessories, or storing the tool. Such preventive safety measures reduce the risk of starting the tool accidentally. (5) Store idle tools out of reach of children and other untrained persons. Tools are dangerous in the hands of untrained users. (6) 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. (7) 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 by a HITACHI authorized service center before using. Many accidents are caused by poorly maintained tools. (8) 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 with another tool.

(1) Tool service must be performed only by a HITACHI authorized service center. Service or maintenance performed by unqualified personnel could result in a risk of injury. (2) 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 Instruction may create a risk of electric shock or injury.English

To ensure safer operation of this power tool, HITACHI has adopted a double insulation design. “Double insulation “ means that two physically separated insulation systems have been used to insulate the electrically conductive materials connected to the power supply from the outer frame handled by the operator. Therefore, either the symbol “ ” or the words “Double insulation” appear on the power tool or on the nameplate. Although this system has no external grounding, you must still follow the normal electrical safety precautions given in this Instruction Manual, including not using the power tool in wet environments. To keep the double insulation system effective, follow these precautions: 䡬 Only HITACHI AUTHORIZED SERVICE CENTER should disassemble or assemble this power tool, and only genuine HITACHI replacement parts should be installed. 䡬 Clean the exterior of the power tool only with a soft cloth moistened with soapy water, and dry thoroughly. Never use solvents, gasoline or thinners on plastic components; otherwise the plastic may dissolve.

SAVE THESE INSTRUCTIONS

FUNCTIONAL DESCRIPTION NOTE: The information contained in this Instruction Manual is designed to assist you in the safe operation and maintenance of the power tool. NEVER operate, or attempt any maintenance on the tool unless you have first read and understood all safety instructions contained in this manual. Some illustrations in this Instruction Manual may show details or attachments that differ from those on your own power tool

APPLICATIONS 䡬 Boring holes in metal, wood and plastic.

Ensure that the power source to be utilized conforms to the power source requirements specified on the product nameplate.

Ensure that the switch is in the OFF position. If the plug is connected to a receptacle while the switch is in the ON position, the power tool will start operating immediately and can cause serious injury.

When the work area is far away from the power source, use an extension cord of sufficient thickness and rated capacity. The extension cord should be kept as short as practicable.

Damaged cord must be replaced or repaired.

4. Check the receptacle

If the receptacle only loosely accepts the plug, the receptacle must be repaired. Contact a licensed electrician to make appropriate repairs. If such a fautly receptacle is used, it may cause overheating, resulting in a serious hazard.

5. Check your work environment:

Confirm that the work site is placed under appropriate conditions conforming to prescribed precautions.

6. Selecting the appropriate drill bit:

䡬 When boring metal or plastic Use an ordinary metalworking drill bit. 䡬 When boring wood Use an ordinary woodworking drill bit. However, when drilling 1/4" (6.5 mm) or smaller holes, use a metalworking drill bit.English

7. Mounting drill bits (Fig. 2)

Tighten drill bits with the chuck wrench. There are three holes in which the chuck wrench should be inserted. Tighten them equally in turn at three holes, without tightening them only at one hole. The drill bit can be removed in the opposite method as mentioned above.

8. Confirm the direction of bit rotation

(Fig. 3) The bit rotates clockwise (viewed from the top side) by pushing the R-side of the reversing switch lever. The L-side of the lever is pushed to turn the bit counterclockwise. CAUTION Never change the direction of bit rotation while operating. Turn the power switch OFF before changing the direction of bit rotation; otherwise, burning of the motor will result.

9. Fixing the side handle

Screw the side handle into the gear cover.

CAUTION: To prevent accidents, make sure to turn the switch off and disconnect the plug from the receptacle when the drill bits and other various parts are installed or removed. The power switch should also be turned off during a work break and after work.

1. Operation of switch

䡬 Turning the switch on Slide the switch lever on the main body backward as illustrated in Fig. 5. When you slide it backward completely, the switch gets turned on and locked in that condition. Fig. 2 Drill chuck Chuck Wrench Fig. 3 Reversing switch lever

䡬 Turning the switch off Press the round convex on the surface of the switch lever as illustrated in Fig. 6. Then, the lock comes off, the switch lever returns forward on the main body by the spring’s force, and the switch gets turned off.

2. Pressing force of drill

You can not get holes quickly even if pressing it by strong force more than necessary. It not only damages the tip of drill bits and decreases the efficiency of operation, but also shortens the life of the drill.

3. When drilling completely through the

material When the drill bit bores completely through the material, careless handling often results in a broken drill bit or damage to the drill body itself due to the sudden movement of the drill. Always be alert and ready to release pushing force and hold the drill body securely with both hands when drilling through the material.

4. Adjusting the drilling speed

D10YB is equipped with electric control circuit which enables non-step speed control. To adjust the speed, turn the dial shown in Fig. 7. When the dial is set to “1”, the drilling speed is minimum speed (500/min). When the dial is set to “5”, the drilling speed is maximum speed (2300/min). Adjust the drilling speed according to the material. NOTE: When the dial is set to “1”, there can be cases where no rotation takes place due to a power situation, etc. In this case, raise the dial slightly before use.

WARNING: Be sure to switch power OFF and disconnect the plug from the receptacle

during maintenance and inspection.

1. Inspecting the drill bits

Since use of a dull tool will cause motor malfunctioning and degraded efficiency, replace the drill bit with a new one or resharpening without delay when abrasion is noted.

2. Inspecting the screws

Regularly inspect all screws and ensure that they are fully tightened. Should any of the screws be loosened, retighten them immediately.

WARNING: Using this drill with loosened screws is extremely dangerous.

3. Keeping after use

When not in use, the Power tool should be kept in a dry place out of the reach of children.

4. Inspecting the carbon brushes (Fig. 8)

The motor employs carbon brushes which are consumable parts. Replace the carbon brush with a new one when it becomes worn to its wear limit. Always keep carbon brushes clean and ensure that they slide freely within the brush holders. CAUTION: Using this portable grinder with a carbon brush which is worn in excess of the wear limit will damage the motor. NOTE: Use HITACHI carbon brush No. 21 indicated in Fig. 8.

5. Replacing carbon brushes

Remove the brush caps (Fig. 1) with a slotted screwdriver. The carbon brushes can then be easily removed.

6. Maintenance of the motor

The motor unit winding is the very “heart”’ of the power tool. Exercise due care to ensure the winding does not become damaged and/or wet with oil or water.

7. Service and repairs

All quality power tools will eventually require servicing or replacement of parts because of wear from normal use. To assure that only authorized replacement parts will be used, all service and repairs must be performed by a HITACHI AUTHORIZED SERVICE CENTER, ONLY. 0.47" (12 mm) 0.20" (5 mm) Wear Limit No. of Carbon Brush
