Suction Hose (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.
