CAUTION
○ When removing the center pin and the guide plate,
turn OFF the switch and disconnect the plug from the
receptacle.
○ Application of excessive force will not only expedite
the work, but will deteriorate the tip edge of the drill bit,
resulting in reduced service life of the rotary hammer.
3. Dismounting (Fig. 23)
Remove the core bit shank from the rotary hammer
and strike the head of the core bit shank strongly two or
three times with a hammer holding the core bit, then the
thread becomes loose and the core bit can be removed.
LUBRICATION
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 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.
CAUTION
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.
MAINTENANCE AND INSPECTION
1. Inspecting the tools
Since use of a dull tool will cause motor malfunctioning
and degraded effi 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.
