The Wand System isn’t aspirating fully. How can this be fixed?
If the unit isn’t performing a full aspiration, remove the cartridge of anesthetic,
put the unit in NORMAL Mode, turn the auto retract/purge light off and step
on the foot control to expose the plunger on the top of the unit fully. Once the
plunger is in full view, inspect the plunger and check the 0-ring to see if it is
worn, dry or cracked. If so, rep lace the 0-ring and lightly lubricate the 0-ring
