slow jack movement or extremely rapid jerks, causing damage to the internal components. To keep the jack well lubricated,
carry out the following steps.
6.1.1 Lubricate the linkages, the saddle, and the pump mechanism with light oil.
6.1.3 Keep all jack surfaces and warning labels clean.
6.1.4 Check and maintain the ram oil level (Section 6.3).
6.2 THREE-MONTH MAINTENANCE
6.2.1 At three-month intervals, check the pump for any signs of rust or corrosion. Clean the pump as required and
wipe with an oilcloth.
6.3 CHECKING THE OIL LEVEL
6.3.1 Fully retract the ram by turning the release valve counterclockwise.
6.3.2 Loosen the four top plate retaining screws (no need to screw out) and remove the top plate vertically
as per the following picture.
