LUBRICATION
Whenever a Series 88S Sander is disassembled for overhaul
or replacement of parts, lubricate as follows:
1.
Inject about 1.5 cc of Ingersoll–Rand No. 50 Oil into
the Inlet Bushing (4) after assembly.
2.
If the Sander is used in an extremely dirty
environment, once each week or after each forty
hours of operation, pour a liberal amount of a suitable
cleaning solution into the slots in the handle. Work the
throttle lever vigorously to wash the cleaning solution
around, then pour the solution and accumulated dirt
from the handle. Repeat this process until the cleaning
solution is clean when it comes out of the handle.
Immediately after flushing with the cleaning solution,
inject a liberal amount of Ingersoll–Rand No. 50 Oil in
the slots and, again, work the throttle lever vigorously
to lubricate the cleaned parts.
