4. MAINTENANCE
Check operating conditions periodically, so that the machine can always be used in good
condition.
Especially, perform the following maintenance work periodically.
4-1. CLEANING FILTER FOR COOLING FAN
CAUTION
It is recommended to clean the filter every work day, although cleaning cycle depends on
frequency of use and work environment.
If cleaning is neglected, dusts may accumulate to more than a few millimeters thickness on the
filter.
Dusts accumulation or clogging of filter may cause trouble of the machine (flow of cooling air is
shut off ---> cooling does not work ---> temperature of internal electric circuit rises --->
malfunction).
1) Move the filter cover downward to remove.
2) The filter can be removed together with the filter cover.
3) Clean the filter.
4) Assemble the filter and the filter cover again,
so that each hook of the filter cover will be caught by each
groove of the fan body.
4-2. CLEANING OF FURNACE AND ROTATING UNIT
1) When waste has accumulated, collect it by sucking with a vacuum cleaner available on the
market.
2) If clogging happened in the wax collecting hole, push it through with a screwdriver or the like.
