(Models 232132 and 232133)
WARNING
INJECTION HAZARD
To reduce the risk of serious injury, when
instructed to relieve pressure, follow the
Pressure Relief Procedure on page 8.
1. Relieve pressure.
2. Remove drain hose (50) from clip.
3. Pull upward on suction hose (47) while unscrewing
it from inlet tube (43). The hose coupling (A)
threads will engage and the hose will separate
from the tube.
4. Replace o-ring (45) if it is worn or damaged.
5. Lubricate o-ring (45) and inlet tube (43) threads
with light grease.
6. Align suction hose coupling (A) with threads of
inlet tube (43). Tighten hose onto tube at least 4
turns to ensure that threads have disengaged and
can function as a swivel joint.
CAUTION
Misalignment or cross-threading will damage the
parts and/or create shavings which can cause the
o-ring (45) to leak.
