GREASE REPLACEMENT
This Rotary Hammer is of full air-tight construction to protect
against dust.
Therefore, this Rotary Hammer can be used without
lubrication for long periods. Replace the grease as described
below.
Grease Replacement Period
After purchase, replace grease after every 6 months of
usage. Ask for grease replacement at the nearest authorized
Service Center.
MAINTENANCE AND INSPECTION
1. Inspecting the drill bits
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.
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. Replacing supply cord
If the replacement of the supply cord is necessary, this
has to be done by HiKOKI Authorized Service Center to
avoid a safety hazard.
CAUTION
In the operation and maintenance of power tools, the
safety regulations and standards prescribed in each
country must be observed.
