Testing
Before starting a task, it is recommended that you check the vibration
frequency using excess material.
SELECTION OF APPLICATION TOOL
○
Application tools
To ensure maximum operating effi ciency and results, it is very important
to select the appropriate blade best suited to the type and thickness of
the material to be cut.
For details contact Hitachi Authorized Service Center.
MAINTENANCE AND INSPECTION
1.
Inspecting the application tool
Continued use of a dull or damaged application tool will result in reduced
cutting effi ciency and may cause overloading of the motor. Replace the
application tool with a new one as soon as excessive abrasion is noted.
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.
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.
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.
5.
Storage
Store the power tool 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.
○
Storing lithium-ion batteries.
Make sure the lithium-ion batteries have been fully charged before
storing them.
Prolonged storage 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.
