above in reverse order.

MAINTENANCE AND INSPECTION

1. Inspecting the blades
Continued use of dull or damaged blades will result
in reduced cutting efficiency and may cause
overloading of the motor. Sharpen or replace the
blades as often as necessary.
2. Handling
CAUTION
The front base, rear base, and cutting depth control
knob are precisely machined to obtain specifically high
precision. If these parts are roughly handled or
subjected to heavy mechanical impact, it may cause
deteriorated precision and reduced cutting
performance. These parts must be handled with
particular care.
3. 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.
4. Inspecting the carbon brushes (Fig. 28)
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. shown in the figure when it becomes
worn to or near the "wear limit". In addition, always
keep carbon brushes clean and ensure that they
slide freely within the brush holders.
5. Replacing carbon brushes
After removing the chip cover, use a slotted
screwdriver to disassemble the brush caps. The
carbon brushes can then be easily removed with
the spring.

The motor unit winding is the very "heart" of the
power tool.
Exercise due care to ensure the winding does not

this has to be done by HiKOKI Authorized Service
Center in order to avoid a safety hazard.
