USER MANUAL DH 24DVC(S) HITACHI

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.

a) Keep work area clean and well lit. Cluttered or dark areas invite accidents. b) 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. c) Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

2) Electrical safety

a) 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. b) 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. c) Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock. d) 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. e) 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. f) If operating a power tool in a damp location is unavoidable, use a residual current device (RCD) protected supply. Use of an RCD reduces the risk of electric shock.

a) 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. b) 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. c) 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. d) 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. e) Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations. f) 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. g) 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.

4) Power tool use and care

a) 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. b) 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. c) 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. d) 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. e) Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tools operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools. f) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control. g) 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. (Original instructions) 01Eng_DH24DVC(S)_WE 4/17/12, 9:2378 English

5) Battery tool use and care

a) Recharge only with the charger specified by the manufacturer. A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack. b) Use power tools only with specifically designated battery packs. Use of any other battery packs may create a risk of injury and fire. c) When battery pack is not in use, keep it away from other metal objects like paper clips, coins, keys, nails, screws, or other small metal objects that can make a connection from one terminal to another. Shorting the battery terminals together may cause burns or a fire. d) Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns.

a) 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. PRECAUTION Keep children and infirm persons away. When not in use, tools should be stored out of reach of children and infirm persons.

Table 2 (3) Regarding recharging time Depending on the type of the battery, the charging time will become as shown in Table 3. Table 3 Charging time (At 20°C) NOTE: The charging time may vary according to ambient temperature and power source voltage.

4. Disconnect the charger’s power cord from the

5. Hold the charger firmly and pull out the battery.

NOTE After operation, pull out batteries from the charger first, and then keep the batteries properly. Regarding electric discharge in case of new batteries, etc. As the internal chemical substance of new batteries and batteries that have not been used for an extended period is not activated, the electric discharge might be low when using them the first and second time. This is a temporary phenomenon, and normal time required for recharging will be restored by recharging the batteries 2–3 times. How to make the batteries perform longer (1) Recharge the batteries before they become completely exhausted. When you feel that the power of the tool becomes weaker, stop using the tool and recharge its battery. If you continue to use the tool and exhaust the electric current, the battery may be damaged and its life will become shorter. (2) Avoid recharging at high temperatures. A rechargeable battery will be hot immediately after use. If such a battery is recharged immediately after use, its internal chemical substance will deteriorate, and the battery life will be shortened. Leave the battery and recharge it after it has cooled for a while. CAUTION 䡬 If the battery is charged while it is heated because it has been left for a long time in a location subject to direct sunlight or because the battery has just been used, the pilot lamp of the charger lights for 1 second, does not light for 0.5 seconds (off for

0.5 seconds). In such a case, first let the battery

cool, then start charging. 䡬 Since the built-in micro computer takes about 3 seconds to confirm that the battery being charged with UC24SGH is taken out, wait for a minimum of 3 seconds before reinserting it to continue charging. If the battery is reinserted within 3 seconds, the battery may not be properly charged.

1. Mounting the drill bit (Fig. 4, 5)

CAUTION To prevent accidents, make sure to turn the switch off. NOTE When using tools such as drill bits, etc., make sure to use the genuine parts designated by our company. (1) Clean the shank portion of the drill bit. (2) Insert the drill bit in a twisting manner into the tool holder until it latches itself. (Fig. 4) (3) Check the latching by pulling on the drill bit. (4) To remove the drill bit, fully pull the grip in the direction of the arrow and pull out the drill bit.

2. Confirm that the battery is mounted correctly.

3. Installation of dust cup or dust collector (B) (Optional

accessories) (Fig. 6, Fig. 7) When using a rotary hammer for upward drilling operations attach a dust cup or a dust collector (B) to collect dust or particles for easy operation. 䡬 Installing the dust cup Use the dust cup by attaching to the drill bit as shown in Fig. 6.

The rotation speed of the drill bit can be controlled steplessly by varying the amount that the trigger switch is pulled. Speed is low when the trigger switch is pulled slightly and increases as the switch is pulled more. Continuous operation may be attained by pulling the trigger switch and depressing the stopper. To turn the switch OFF, pull the trigger switch again to disengage the stopper, and release the trigger switch to its original position. However, the switch trigger can only be pulled in halfway during reverse and rotates at half the speed of forward operation. The switch stopper is unusable during reverse.

2. Rotation + hammering

This rotary hammer can be set to rotation and hammering mode by turning the change lever to the mark (Fig. 9). (1) Mount the drill bit. (2) Pull the trigger switch after applying the drill bit tip to the drilling position (Fig. 10). (3) Pushing the rotary hammer forcibly is not necessary at all. Pushing slightly so that drill dust comes out gradually is sufficient. CAUTION When the drill bit touches construction iron bar, the bit will stop immediately and the rotary hammer will react to revolve. Therefore grip the side handle and handle tightly as shown in Fig. 10.

This rotary hammer can be set to rotation only mode by turning the change lever to the mark (Fig. 11). To drill wood or metal material using the drill chuck and chuck adapter (optional accessories), proceed as follows. Installing drill chuck and chuck adapter (Fig. 12). (1) Attach the drill chuck to the chuck adapter. (2) The part of the SDS-plus shank is the same as the drill bit. Therefore, refer to the item of “Mounting the drill bit” for attaching it. CAUTION 䡬 Application of force more than necessary will not only expedite the work, but will deteriorate the tip edge of the drill bit and reduce the service life of the rotary hammer in addition. 䡬 Drill bits may snap off while withdrawing the rotary hammer from the drilled hole. For withdrawing, it is important to use a pushing motion. 䡬 Do not attempt to drill anchor holes or holes in concrete with the machine set in the rotation only function. 䡬 Do not attempt to use the rotary hammer in the rotation and striking function with the drill chuck and chuck adapter attached. This would seriously shorten the service life of every component of the machine.

4. When driving machine screws (Fig. 13)

First, insert the bit into the socket in the end of chuck adapter (D). Next, mount chuck adapter (D) on the main unit using procedures described in 4 (1), (2), (3), put the tip of the bit in the slots in the head of the screw, grasp the main unit and tighten the screw. 䡬 Installing dust collector (B) When using dust collector (B), insert dust collector (B) from the tip of the bit by aligning it to the groove on the grip. (Fig. 7) CAUTION 䡬 The dust cup and dust collector (B) are for exclusive use of concrete drilling work. Do not use them for wood or metal drilling work. 䡬 Insert dust collector (B) completely into the chuck part of the main unit. 䡬 When turning the rotary hammer on while dust collector (B) is detached from a concrete surface, dust collector (B) will rotate together with the drill bit. Make sure to turn on the switch after pressing dust cup on the concrete surface. When using dust collector (B) attached to a drill bit that has more than 190 mm of overall length, dust collector (B) cannot touch the concrete surface and will rotate. Therefore, please use dust collector (B) by attaching to drill bits which have 166 mm, 160 mm, and 110 mm overall length. 䡬 Dump particles after every two or three holes when drilling. 䡬 Please replace the drill bit after removing dust collector (B).

4. Selecting the driver bit

Screw heads or bits will be damaged unless a bit appropriate for the screw diameter is employed to drive in the screws.

5. Confirm the direction of bit rotation (Fig. 8)

The bit rotates clockwise (viewed from the rear side) by pushing the R-side of the push button. (Fig. 8-a) The L-side of the push button is pushed to turn the bit counterclockwise. (Fig. 8-b)

6. Continuous drilling

The number of holes that can be drilled in concrete after one recharge is shown in Table 4. Table 4 These data are for the referential values. The number of holes that can be drilled varies according to the sharpness of the used bit or the conditions of the concrete being drilled. CAUTION When using this unit continuously, the unit may overheat, leading to damage in the motor and switch. Please leave it without using it for approximately 15 minutes. 01Eng_DH24DVC(S)_WE 4/17/12, 9:231314 English CAUTION 䡬 Exercise care not to excessively prolong driving time, otherwise, the screws may be damaged by excessive force. 䡬 Apply the rotary hammer perpendicularly to the screw head when driving the screw; otherwise, the screw head or bit will be damaged, or driving force will not be fully transferred to the screw. 䡬 Do not attempt to use the rotary hammer in the rotation and hammering function with the chuck adapter and bit attached.

5. When driving wood screws (Fig. 13)

(1) Selecting a suitable driver bit Employ plus-head screws, if possible, since the driver bit easily slips off the heads of minus-head screws. (2) Driving in wood screws 䡬 Prior to driving in wood screws, make pilot holes suitable for them in the wooden board. Apply the bit to the screw head grooves and gently drive the screws into the holes. 䡬 After rotating the rotary hammer at low speed for a while until the wood screw is partly driven into the wood, squeeze the trigger more strongly to obtain the optimum driving force. CAUTION Exercise care in preparing a pilot hole suitable for the wood screw taking the hardness of the wood into consideration. Should the hole be excessively small or shallow, requiring much power to drive the screw into it, the thread of the wood screw may sometimes be damaged.

This rotary hammer can be set to hammering only mode by turning the change lever to the mark (Fig. 14). (1) Mount the bull point or cold chisel. (2) Set the change lever to middle of mark and mark (Fig. 15). The rotation is released, turn the tool and adjust the cold chisel to desired position (Fig. 16). (3) Turn the change lever to mark (Fig. 14). Then bull point or cold chisel is locked.

7. Using depth gauge (Fig. 17)

(1) Loosen the knob on the side handle, and insert the depth gauge into the mounting hole on the side handle. (2) Adjust the depth gauge position according to the depth of the hole and tighten the knob securely.

8. How to use the drill bit (taper shank) and the taper

shank adapter (1) Mount the taper shank adapter to the rotary hammer (Fig. 18). (2) Mount the drill bit (taper shank) to the taper shank adapter (Fig. 18). (3) Turn the switch ON, and drill a hole in prescribed depth. (4) To remove the drill bit (taper shank), insert the cotter into the slot of the taper shank adapter and strike the head of the cotter with a hammer supporting on a rests (Fig. 19). LUBRICATION Low viscosity grease is applied to this rotary hammer so that it can be used for a long period without replacing the grease. Please contact the nearest service center for grease replacement when any grease is leaking form loosened screw. Further use of the rotary hammer despite the grease shortage causes damage to reduce the service life. CAUTION A specific grease is used with this machine, therefore, the normal performance of the machine may be badly affected by use of different grease. Please be sure to let one of our service centers to undertake replacement of the grease.
