MAINTENANCE:
All components should be kept clean and free
from dirt and grit.
The adapter screws and ratchet wrench mov-
ing parts should be kept well lubricated with a
#20 oil.
The driver unit screw, internal housing thread,
and steel balls should be lubricated periodical-
ly with a molybdenum disulfide based lubricat-
ing grease. Keeping the unit lubricated will not
only reduce wear but will also result in easier
operation.
