What is the APA 6000 analyser autoburette lubrication procedure?
Instructions for APA 6000 autoburette lubrication (monthly lubrication is required).
The APA6000 autoburette lead screw must be lubricated periodically to prevent excess wear and premature motor failure.  Monthly lubrication must be performedwith Hach-specified grease only – per the following instructions.  Refer to the APA6000 Process Analyser Instruction and Maintenance Manual for additional maintenance requirements. 
1.  Open the APA6000 enclosure and observe the movement of the autoburette piston.  Turn OFF the analyser power switch when the piston is at its fully retracted position.

2.  Remove the front panel retaining screws (from the upper left- and right-hand corners of the panel).  Pull forward at the top of the panel and lower it to the horizontal position. 

3.  Locate the autoburette lead screw; you will see this protruding approximately 2” (5 cm) from the back of the autoburette module.  Apply a thin bead of grease to the lead screw and wipe off excess with a tissue.  Do not apply excessive lubricant!  A thin film of lubrication is sufficient. 
4.  Raise the panel to its upright position and reapply power.
