MAINTENANCE AND INSPECTION
The plug must be

cleaning.
1. Storage and cleaning
When a mixer is not in use store it in dry locations the
motor part upwards.
When cleaning a mixer avoid entrance of any water or
liquid to the motor part.
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
The motor employs carbon brushes which are
consumable parts. Since an excessively worn carbon
brush can result in motor trouble, replace the carbon
brushes with new ones having the same carbon brush
No.. In addition, always keep carbon brushes clean and
ensue that they slide freely within the brush holders.
CAUTION
When replacing the new carbon brushes, always use
genuine HiKOKI carbon brushes with the number
speci
fi
ed in the drawing.
5. Replacing carbon brushes
Disassemble the brush caps with a slotted-head
screwdriver. The carbon brushes can then be easily
removed. Contact the HiKOKI Authorized Service Center
when repurchasing carbon brushes.
6. Replacing supply cord
If the supply cord of Tool is damaged, the Tool must be
returned to HiKOKI Authorized Service Center for the
cord to be replaced.
If it becomes necessary to replace the connecting cable,
then this is to be undertaken by the manufacturer or his
representative in order to avoid any safety risks.
CAUTION
In the operation and maintenance of power tools, the
safety regulations and standards prescribed in each
country must be observed.
