NOTE

○ This function helps prevent nuts from dropping when

loosening them.

○ Depending on factors such as the bolt or nut size,

socket used, and extent of tightening, there is a risk of

nuts accidentally dropping if the nut becomes detached

from the screw thread while the power tool is operating.

MAINTENANCE AND INSPECTION

WARNING

Be sure to turn off the switch and remove the battery

before maintenance and inspection.

1. Inspecting the socket

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.

2. 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

could result in serious hazard.

TROUBLESHOOTING

Use the inspections in the table below if the tool does not operate normally. If this does not remedy the problem, consult

your dealer or the HiKOKI Authorized Service Center.

3. 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.

4. Inspection of terminals (tool and battery)

Check to make sure that swarf and dust have not

collected on the terminals.

On occasion check prior, during and after operation.

CAUTION

Remove any swarf or dust which may have collected on

the terminals.

Failure to do so may result in malfunction.

5. Cleaning on the outside

When the power tool is stained, wipe with a soft dry

cloth or a cloth moistened with soapy water. Do not use

chloric solvents, gasoline or paint thinner, for they melt

plastics.

6. Storage

Store the power tool and battery in a place in which the

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

children.

NOTE

Storing lithium-ion batteries.

Make sure the lithium-ion batteries have been fully

charged before storing them.

Prolonged storage (3 months or more) of batteries with

a low charge may result in performance deterioration,

significantly reducing battery usage time or rendering

the batteries incapable of holding a charge.

However, significantly reduced battery usage time may

be recovered by repeatedly charging and using the

batteries two to five times.

If the battery usage time is extremely short despite

repeated charging and use, consider the batteries dead

and purchase new batteries.

CAUTION

In the operation and maintenance of power tools, the

safety regulations and standards prescribed in each

country must be observed.

Important notice on the batteries for the HiKOKI

cordless power tools

Please always use one of our designated genuine

batteries. We cannot guarantee the safety and

performance of our cordless power tool when used with

batteries other than these designated by us, or when the

battery is disassembled and modified (such as

disassembly and replacement of cells or other internal

parts).

NOTE

Due to HiKOKI's continuing program of research and

development, the specifications herein are subject to

change without prior notice.
