6.2 Service and Maintenance
Please make sure that you read this chapter thoroughly. Proper handling and cleaning of the
Roboinject will ensure reliable and long life time of the equipment. Most often, troubles are
simply due to mishandling. See also chapter "Troubleshooting".
6.2.1 Cleaning the x/y Table
You prevent a malfunction of the carrier by cleaning the x/y table regularly.
Use a soft tissue and pure alcohol (100 %) to clean the x/y table.
Warning: Water may provoke a corrosion of the carrier. Residues of cleaning
agents may interfere with the function of the carrier or damage the surface
of the x/y table. Do not use an aqueous solution or cleaning agents.
6.2.2 Replacing the Plunger
To replace the plunger inside the injector mount, please remove the cover of the injector mount
by pulling it into upward forward direction. Unscrew the screws on the second lid of the injector
mount, and remove the smaller cover. First, open one of the screws of the plunger brackets only.
Use the allen key from the accessory package. Pull out the old plunger. If the plunger does not
come out easily, also loosen the second screw. Disconnect the plunger and move it downward
through the hole at the bottom of the injector mount which leads to the luer lock for the
injection needle.
Insert a new plunger on the same way. Insert it into the plunger bracket. Tighten the screws.
The two screws in the plunger bracket squeeze the plunger between each other, and allow to
adjust the plunger. The plunger should be aligned without tension between the plunger brackets
and the hole at the bottom of the injector mount which leads to the luer lock for the injection
needle. You can correct the alignment by loosen one screw and tighten the other.
