FFS2001 Series
Priming the Remote Manual Injection System
The following procedure is required to prime the remote manual injection system:
1. Make sure to have lens tissue and cleaning solution (acetone or alcohol) available prior to proceeding.
2. Raise the recoater top.
3. Position the selection lever of the remote injector to the inject position (lever horizontal) and screw in
(turn clockwise) the knurled syringe screw until a slight resistance is felt at the end of travel. Do not use
excessive force when turning in the screw once the end of travel is reached. The end of travel point is
reached when the leading edge of the syringe screw is approximately level with the step in the syringe
body.
4. Fit a recoat bottle with fresh recoat material to the system. The red inject tube should be long enough to
just reach the bottom of the recoat bottle. If using a shorter bottle than the supplied (30 ml) recoat bottle
the red tube may need to be trimmed to length.
5. Turn the selection lever to the fill position (lever down). Unscrew (turn counterclockwise) the knurled
syringe screw to draw recoat material from the bottle into the syringe. Continue unscrewing the syringe
screw approximately 3/4" or until it is felt to spin freely.
6. Turn the selection lever to the inject position (lever horizontal) and screw in (turn clockwise) the syringe
screw until the inject end of travel point is reached.

Do not pull on the syringe screw once the end of travel is reached; this will pull the
plunger out form the syringe body.
If the syringe screw was fully unscrewed until is spun freely, a slight forward pressure
may initially be required to re-engage the threads.
