8.2 REPLACEMENT OF OIL SEAL
When Oil Seals (Water Seals) are worn out, water would be leaked from a small
hole on water hose connection’s plug hole.
If you find the water leakage, bring your machine to your nearest Shibuya’s
authorized dealer to have the Oil Seal replaced.
NOTE
Replace both sides of Carbon Brushes at the same time. Till new Carbon Brushes get accustomed with
the commutator portions of Armature, do not apply much force when drilling. Use only Shibuya’s genuine
Carbon Brushes for replacement.
