Cautions
Eeospcsa3007
The drip-proof bushing of MIV06, MIV08, or MPS10 used for the machine delivered before June
1999 is fixed with silicone rubber for the enhancement of water tightness of the motor cable port of
the external cooling fan. (Sufficient water tightness has been verified without silicone rubber and sil-
icone rubber is not used now.)
For this reason, silicone rubber must be removed at the above-mentioned drip-proof bushing during
replacement using sand paper or the like. (If old silicone rubber remains, water tightness may dete-
riorate substantially after replacement.)
