Prime the Tubing
1. Lift the stainer-operating lever to the
PRIME
position and hold in this position until
the stain, buffer, and rinse reagents all flow evenly through their tubes to the platen
without any air bubbles.
NOTE:
If the tubing is new and does not prime easily, it may be necessary to assist the priming
initially. Continue holding the operating lever in the
PRIME
position and push the pump
arm inwards (toward the pump) until the reagent fills the tubing, then release the pump
arm. It may also be helpful to pinch the tubing several times with the fingers, pinching in
the area between the cannula and the pump.

2. Release the lever, which will return automatically to the
LOCK
position.
CAUTION
Always wipe the platen from right to left. Damage to the position or shape of the sensing
switch fingers may result from not following recommended cleaning practices. Check the
position of the fingers after cleaning as described in step 5 of
Check and Correct
Instrument Operation Prior to Pump Volume Adjustment on page 6-15.
3. After priming, wipe the platen with a soft disposable, lint-free absorbent cloth or
tissue.
