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.

English

5

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.

English

Battery

English

14

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.

6. Switch operation

䡬 When the trigger switch is depressed, the tool rotates. When the trigger is released, the

tool stops.

䡬 The rotational speed can be controlled by varying the amount that the trigger switch is

pulled. Speed is low when the trigger switch is pulled slightly and increases as the

trigger switch is pulled more.

NOTE: A buzzing noise is produced when the motor is about to rotate; this is only a noise,

not a machine failure.

7. Tightening and loosening screws

Install the bit that matches the screw, line up the bit in the grooves of the head of the

screw, then tighten it.

Push the impact driver just enough to keep the bit fitting the head of the screw.

CAUTION

䢇 Applying the impact driver for too long tightens the screw too much and can break it.

䢇 Tightening a screw with the impact driver at an angle to that screw can damage the

head of the screw and the proper force will not be transmitted to the screw.

Tighten with this impact driver lined up straight with the screw.

8. Number of screw tightenings possible

Please refer to the table below for the number of screw tightenings possible with one

charge.

<WH14DAF2> (EB1414S)

These values may vary slightly, according to surrounding temperature and battery

characteristics.

OPERATIONAL CAUTIONS

1. Resting the unit after continuous work

After use for continuous bolt-tightening work, rest the unit for 15 minutes or so when

replacing the battery. The temperature of the motor, switch, etc., will rise if the work is

started again immediately after battery replacement, eventually resulting in burnout.

CAUTION:

Do not touch the hammer case, as it gets very hot during continuous work.

2. Cautions on use of the speed control switch

This switch has a built-in, electronic circuit which steplessly varies the rotation speed.

Consequently, when the switch trigger is pulled only slightly (low speed rotation) and

the motor is stopped while continuously driving in screws, the components of the

electronic circuit parts may overheat and be damaged.

3. Tightening torque

Refer to Fig. 15 for the tightening torque of bolts (according to size), under the conditions

shown in Fig. 16. Please use this example as a general reference, as tightening torque

will vary according to tightening conditions.

NOTE: 䡬 If a long striking time is used, screws will be strongly tightened. This may cause

the screw to break, or may damage the end of the bit.

䡬 If the unit is held at an angle to the screw being tightened, the head of the

screw may be damaged, or the specified torque may not be transmitted to the

screw. Always keep the unit and the screw being tightened in a straight line.

4. Use a tightening time suitable for the screw

The appropriate torque for a screw differs according to the material and size of the

screw, and the material being screwed etc., so please use a tightening time suitable for

the screw. In particular, if a long tightening time is used in the case of screws smaller

than 5/16” (8 mm), there is a danger of the screw breaking, so please confirm the

tightening time and the tightening torque beforehand.
