8.17.5 — Air Cleaner
Never operate the air pump without the air cleaner in place. The cleaner itself must be periodically checked and
its element flushed and cleaned semi-annually.
8.17.6 — Flexible Coupling Alignment
Alignment of the pump and motor through the flexible coupling
is extremely important for trouble free operation. Check the cou-
pling alignment semi-annually and replace the coupling insert
as required. Keep the coupling guard in place.
The most commonly used tools for checking alignment are a
small straightedge and a thickness gauge.
The coupling must be checked for both parallel (offset) align-
ment and angular (gap) alignment. Parallel misalignment exists
when shaft axes are parallel but not concentric. Angular mis-
alignment is the reverse situation, with shaft axes concentric but
not parallel.
