LUBRICATION
Low viscosity grease is applied to this rotary hammer so that
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.
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 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. Inspecting the carbon brushes (Fig. 8)
The Motor employs carbon brushes which are
consumable parts. When they become worn to or near
the "wear limit" ⓐ, it results in motor trouble.
When an auto-stop carbon brush is equipped, the motor
will stop automatically. At that time, replace both carbon
brushes with new ones which have the same carbon
brush Numbers ⓑ shown in the Fig. 8. In addition,
always keep carbon brushes clean and ensure that they
slide freely within the brush holders.
