Troubleshooting and Maintenance
Maintenance: Periodically, a small amount of all-purpose oil should be applied to the guide rods.
The mechanism should be kept clean to prevent impeded operation.
No other special maintenance or calibrations are needed
Pusher block makes a snap or click sound when the pump is started: This is a normal condition. When
the pusher block is manually moved, the drive-nut may not have been fully engaged on the drive screw. The
sound heard is the drive-nut engaging on the drive screw.
