Replacing the Syringe Seal
When you replace a syringe seal, also replace the black O-ring that fits inside it. One
package contains four of each.
To replace the syringe seal:
1. Turn off MAGPIX and unplug the power cord.
WARNING: The plunger guide does NOT deactivate while the seal is being
changed; unplugging is necessary to avoid injury.
2. Open the side access door of MAGPIX.
3. Locate the syringe (glass cylinder with a metal rod plunger).
4. Push the plunger guide down. The syringe may fill with clean Drive Fluid.
NOTE: The plunger guide is tight. Be prepared to use some force to push it
down.
5. Unscrew the syringe from the top of its housing and carefully remove it.
6. Pull the plunger out of the syringe and dispose of any Drive Fluid.
7. Using a pair of pliers, remove the white plunger seal (at the top of the plunger) and
discard it.
8. Place the black O-ring inside the new white plunger seal and press the seal down on the
top of the plunger.
9. Return the plunger to the syringe.
