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 fi tting 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 may result in
serious hazard.
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.
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
Storing Lithium-ion Batteries
Make sure the 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, signifi cantly reducing battery usage time or rendering the
batteries incapable of holding a charge.
However, signifi cantly reduced battery usage time may be recovered by repeatedly
charging and using the batteries two to fi ve times.
If the battery usage time is extremely short despite repeated charging and use, consider
the batteries dead and purchase new batteries.
