the plug from the power outlet before inspection
and maintenance.
1. Replacing a cut-o
ff
wheel
When the cut-o

wheel has already become dull while continually using, the unnecessary
load is got from the motor. Consequently, redress or replace a dull cut-o
ff
wheel to ensure
grinding e

ciency.
2. Inspecting the carbon brushes (
Fig. 14
)
The Motor employs carbon brushes which are consumable
parts. When they become worn to or near the “wear limit”,
it could result 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 shown in
the
fi
gure. In addition, always keep carbon brushes clean
and ensure that they slide freely within the brush holders.
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. Replacing supply cord
If the replacement of the supply cord is necessary, this has to be done by HiKOKI
Authorized Service Center in order to avoid a safety hazard.
5. Lubrication
Supply oil in the following oil supply points once a month so as to keep the machine
workable for a long time.
