Pentax EG-2990i Instructions For Use Manual page 30

WARNING:
An inlet seal in good condition (that is not worn or damaged) must be
attached to the instrument channel inlet to prevent the loss of suction and
a risk of cross contamination to the end user due to the potential for reflux
(spit-back) of patient fluids. Worn seals will result in leakage and should be
replaced. To ensure maximum performance of these sealing mechanisms,
consider replacing the inlet seal with a fully reprocessed new one for each
procedure.
d) Release the suction control valve to determine if the valve freely returns to its
OFF position and the aspiration of water ceases.
e) If the suction control valve does not move smoothly or feels "sticky", remove the
valve from the suction cylinder on the control body of the endoscope. Apply a
small amount of silicone oil lubricant (OF-Z11) onto rubber part and the O-ring.
Place a small droplet of oil (OF-Z11) on one's sterile gloved forefinger and
gently swirl between thumb and forefinger. Next place the valve with O-ring in-
between thumb and finger and gently rotate the valve so that the oil is evenly
applied to the outer edges of the O-ring.
Remove/wipe off excess lubricant with a soft gauze. Do not use excessive
silicone oil.

9) Inspection of Biopsy Forceps and Instrument Channel
a) Make sure there are no kinks in the flexible shaft of the biopsy forceps.
b) The cups/jaws of the forceps must be free of any residual debris. Any debris
must be cleaned from the forceps before they are used. USE ONLY STERILE
FORCEPS.
c) The handle mechanism on the forceps should be operated to open and close the
cups/jaws. This mechanism should operate freely.
