it can be used for a long period without replacing the grease.
Replace the grease whenever you change the carbon brush
to maintain the service life.
Further use of the rotary hammer with lock off grease will
cause the machine to seize up reduce the service life.

A special grease is used with this machine, therefore,
the normal performance of the machine may be badly
aff ected by use of other grease. Please be sure to let
one of our service agents undertake replacement of the
grease.
Since use of a dull tool will cause motor malfunctioning
and degraded effi ciency, replace the drill bit with new
ones or resharpen them without delay when abrasion is
noted.
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.
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.
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.
If the replacement of the supply cord is necessary, this
has to be done by the manufacturer of this agent in order
to avoid a safety hazard.
In the operation and maintenance of power tools, the
safety regulations and standards prescribed in each
country must be observed.
