Frequently - check all mounting screws and other hardware for tightness & proper jack alignment.

Every 6 months - wax mounting brackets and both inner and outer tubes of jack with automotive wax.

Once each year - fully extend jacks to red safety line. This
redistributes lubrication evenly on the screw shaft. Remove top
cap and re-grease gears (if needed) with white lithium grease.
Lightly oil bearings.

After periods of non-use, or anytime jack seems to labor more than usual, place a few drops of light oil (ie: 3 in 1R) into the oil hole in the crank socket then run the jack to distribute the oil.
