SAFETY

GENERAL SAFETY RULES – FOR ALL BATTERY OPERATED TOOLS

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. Work Area

(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) A battery operated tool with integral batteries or a separate battery pack must be

recharged only with the specified charger for the battery.

A charger that may be suitable for one type of battery may create a risk of fire when

used with another battery.

(2) Use battery operated tool only with specifically designed battery pack.

Use of any other batteries may create a risk of fire.

3. Personal Safety

(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 position before inserting battery.

Carrying tools with your finger on the switch or inserting the battery pack into a

tool with the switch on invites accidents.

(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 enable better control of the tool in unexpected situations.

(6) Use safety equipment. Always wear eye protection. Dust mask, non-skid safety

shoes, hard hat, or hearing protection must be used for appropriate conditions.

01e_dh24dv_e.p65 4/13/04, 11:29 PM4

English

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 battery pack from tool or place the switch in the locked or off position

before making any adjustments, changing accessories, or storing the tools. 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) 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 sparks, burns, or a fire.

(7) 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.

(8) Check for misalignment or binding of moving parts, breakage of parts, and any

other condition that may affect the tools operation. If damaged, have the tool

serviced before using. Many accidents are caused by poorly maintained tools.

(9) 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

on another tool.

5. Service

(1) Tool service must be performed only by qualified repair personnel. 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.

WARNING:

Some dust created by power sanding, sawing, grinding, drilling, and other construction

activities contains chemicals known to the State of California to cause cancer, birth

defects or other reproductive harm. Some examples of these chemicals are:

● Lead from lead-based paints,

● Crystalline silica from bricks and cement and other masonry products, and

● Arsenic and chromium from chemically-treated lumber.

Your risk from these exposures varies, depending on how often you do this type of

work. To reduce your exposure to these chemicals: work in a well ventilated area, and

work with approved safety equipment, such as those dust masks that are specially

designed to filter out microscopic particles.

䡬 Regarding the temperature of the rechargeable battery

The temperatures for rechargeable batteries are as shown in the table below, and

batteries that have become hot should be cooled for a while before being recharged.

䡬 Regarding recharging time

Table 4 shows the recharging time required according to the type of battery.

Table 4 Recharging time (approx. min.) at 68°F (20°C)

NOTE: The recharging time may vary according to ambient temperature and power

source voltage.

4. Disconnect battery charger from the receptacle.

CAUTION:

Do not pull the plug out of the receptacle by pulling on the cord.

Make sure to grasp the plug when removing from receptacle to avoid damaging cord.

5. Remove the battery from the battery charger.

Supporting the battery charger with hand, pull out the battery from the battery charger.

CAUTION:

● When the battery charger has been continuosly used, the battery charger will heated,

thus constituting the cause of the failures. Once the charging has been completed,

give 15 minutes rest until the next charging.

● If the battery is rechraged when it is warm due to battery use or exposure to sunlight,

the pilot lamp may light in green.

The battery will not be recharged. In such a case, let the battery cool before charging.

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.

BEFORE USE

Check the work area to make sure that it is clear of debris and clutter.

Clear the area of unnecessary personnel. Ensure that lighting and ventilation is adequate.

when drilling.

● Please replace the drill bit after removing dust

collector (B).

5. 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.

6. Confirm the direction of bit rotation (Fig. 11)

The bit rotates clockwise (viewed from the rear side) by pushing the R-side of the

push button. (Fig. 11-a)

The L-side of the push button is pushed to turn the bit counterclockwise. (Fig. 11-b)

The motor does not rotate if the push button is set to the center position. (Fig. 11-c)

HOW TO USE

1. Switch operation

䡬 When the switch trigger is depressed, the tool

rotates. When the switch trigger is released, the

tool stops.

䡬 The rotational speed of the rotary hammer can be

controlled by varying the amount that the switch

trigger is pulled. Speed is low when the switch

trigger is pulled slightly and increases as the

switch trigger is pulled more.

䡬 When releasing the switch trigger, the brake will

be applied for immediate stopping.

2. Rotation + Striking

Align the “ ” mark with the “ ” mark by rotating

the change lever to set the “Rotation + Striking”

mode. (Fig. 12)

(1) Mount the drill bit.

(2) Pull the trigger switch after applying the drill bit

tip to the drilling position. (Fig. 13)

(3) Pushing the rotary hammer forcibly is not

necessary at all. Pushing slightly so that drill dust

comes out gradually is just sufficient.

CAUTION:

● When the drill bit touches an iron reinforcing rod,

the bit will stop immediately and the rotary

hammer will react to revolve. Therefore please

grip the side handle and handle tightly as shown

in Fig. 13.

3. Rotation only

Align the “ ” mark with the “ ” mark by rotating

the change lever to set the “Rotation only” mode.

(Fig. 12)

To drill a wood or metal material using the

separately sold drill chuck and chuck adaptor,

proceed as follows. Installing drill chuck and chuck

adaptor (Fig. 14):

(1) Attach the drill chuck to the chuck adaptor.

(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:

● Application of force more than necessary will not only reducing drilling efficiency at

all, but will deteriorate the tip edge of the drill bit and reduce the service life of the

rotary hammer in addition.

● Drill bit may snap off while withdrawing the rotary hammer from the drilled hole. For

withdrawing, it is important to use a pushing motion.

● Do not attempt to drill anchor holes or holes in concrete with the main unit in the

rotation only mode.

● Do not attempt to use the rotary hammer in the rotation and striking mode with the

drill chuck and chuck adaptor attached. This would seriously shorten the service life of

every components of the machine.

4. When driving machine screws (Fig. 15)

First, insert the bit into the socket in the end of

chuck adaptor (D).

Next, mount chuck adaptor (D) on the main unit

using procedures described in 3 (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.

CAUTION:

● Exercise care not to excessively prolong driving

time, otherwise, the screws may be damaged by

excessive force.

● Apply the rotary hammer perpendicularly to the

screw head when driving a screw; otherwise, the

screw head or bit will be damaged, or driving force

will not be fully transferred to the screw.

● Do not attempt to use the rotary hammer in the

rotation and striking mode with chuck adaptor

(D) and bit attached.
