LUBRICATION
This Rotary Hammer is of full air-tight construction to protect
against dust and to prevent lubricant leakage.
Therefore, this Rotary Hammer can be used without
lubrication for long periods. Replace the grease whenever
you change the carbon brush to maintain the service life.
Further use of the rotary hammer with lock o
ff
grease will
cause the machine to seize up reduce the service life.
CAUTION
A special grease is used with this machine, therefore,
the normal performance of the machine may be badly
a
ff
ected by use of other grease. Please be sure to let
one of our service agents undertake replacement of the
grease.
MAINTENANCE AND INSPECTION
1. Inspecting the tools
Since use of a dull tool will cause motor malfunctioning
and degraded e
ffi
ciency, replace the tool with new ones
or resharpen them without delay when 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. Inspecting the carbon brushes
For your continued safety and electrical shock
protection, carbon brush inspection and replacement on
this machine should ONLY be performed by a HiKOKI
Authorized Service Center.
5. Replacing supply cord
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
