WARNING
INJECTION HAZARD
To reduce the risk of serious injury,
whenever you are instructed to relieve
pressure, follow the Pressure Relief
Procedure on page 9.
1.
Remove the drain hose (33) from the clip. Remove
the front cover (13).
2.
Pull upward on the hose (32) while unscrewing it
from the inlet tube (38). The hose coupling (A)
threads will engage and the hose will separate
from the tube.
3.
Replace the o–ring (27) if it is worn or damaged.
4.
Lubricate the o–ring (27) and the inlet tube (38)
threads with light grease.
5.
Align the suction hose coupling with the threads of
the inlet tube (38). Tighten the hose onto the tube at
least 4 turns to ensure that the threads have disen-
gaged 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 (27) to leak.
