MAINTENANCE AND INSPECTION

1. Inspecting the driver bit (WH14DBAL2 / WH18DBAL2)

Using a broken bit or one with a worn out tip is

dangerous because the bit can slip. Replace it.

2. Inspecting the socket (WR14DBAL2 / WR18DBAL2)

A worn or deformed hex. or a square-holed socket will

not give an adequate tightness to the fitting between

the nut or anvil, consequently resulting in loss of

tightening torque. Pay attention to wear of a socket

holes periodically, and replace with a new one if needed.

3. Inspecting the mounting screws

Regularly inspect all mounting screws and ensure

that they are properly tightened. Should any of the

screws be loose, retighten them immediately. Failure

to do so may result in serious hazard.

4. 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.

5. Cleaning of the outside

When the impact driver is stained, wipe with a soft

dry cloth or a cloth moistened with soapy water. Do

not use chloric solvents, gasoline or paint thinner, as

they melt plastics.

6. Storage

Store the impact driver in a place in which the

temperature is less than 40°C, and out of reach of

children.

NOTE:

Make sure that the battery is fully charged when

stored for a long period (3 months or more). The

battery with smaller capacity may not be able to be

charged when used, if stored for a long period.

Information concerning airborne noise and vibration

The measured values were determined according to

EN60745 and declared in accordance with ISO 4871.

Measured A-weighted sound power level:

WH14DBAL2: 92 dB (A)

WH18DBAL2: 91 dB (A)

WR14DBAL2: 91 dB (A)

WR18DBAL2: 91 dB (A)

Measured A-weighted sound pressure level:

WH14DBAL2: 73 dB (A)

WH18DBAL2: 72 dB (A)

WR14DBAL2: 72 dB (A)

WR18DBAL2: 72 dB (A)

Uncertainty KpA: 3 dB (A).

Wear hearing protection.

Vibration total values (triax vector sum) determined

according to EN60745.

Impact tightening of fasteners of the maximum capacity

of the tool:

Vibration emission value

= WH14DBAL2: 9.2 m/s

WH18DBAL2: 10.6 m/s

WR14DBAL2: 8.9 m/s

WR18DBAL2: 8.6 m/s

Uncertainty K = 1.5 m/s

The declared vibration total value has been measured in

accordance with a standard test method and may be

used for comparing one tool with another.

It may also be used in a preliminary assessment of

exposure.

WARNING

⅜ The vibration emission during actual use of the power

tool can differ from the declared total value depending

on the ways in which the tool is used.

⅜ Identify safety measures to protect the operator that

are based on an estimation of exposure in the actual

conditions of use (taking account of all parts of the

operating cycle such as the times when the tool is

switched off and when it is running idle in addition to

the trigger time).
