MAINTENANCE AND INSPECTION
WARNING
Be sure to switch power OFF and disconnect the plug from the receptacle during maintenance and
inspection.
1. Inspecting the blade
Continued use of a dull or damaged blade will result in
reduced cutting effi ciency and may cause overloading
of the motor. Replace the blade with a new one as
soon as excessive abrasion is noted.
CAUTION
If a dull saw blade is used, reactive force is
increased during cutting operation. Avoid the
use of the dull saw blade without repair.
2. Check the Screws
Loose screws are dangerous. Regularly inspect them
and make sure they are tight.
CAUTION
Using this power tool with loosened screws is
extremely dangerous.
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. Inspecting the carbon brushes
For your continued safety and electrical shock
protection, carbon brush inspection and replacement
on this tool should ONLY be performed by a Hitachi
Authorized Service Center.
5. Check for Dust
Dust may be removed with a soft cloth or a cloth
dampened with soapy water.
Do not use bleach, chlorine, gasoline or thinner, for
they may damage the plastics.
6. Lubrication
The bearings in this tool have been suffi ciently
lubricated with quality lubricating oil, taking into
account the expected life of this tool under normal
operating conditions. As a result, no further lubrication
is necessary.
7. Service and repairs
All quality power tools will eventually require servicing
or replacement of parts because of wear from normal
use. To assure that only authorized replacement
parts will be used, all service and repairs must be
performed by a HITACHI AUTHORIZED SERVICE
CENTER, ONLY.
