5.1.
When the Jack is not in use, the ram and the handle socket should be in their lowest position
to minimise corrosion. Remove the handle to inactivate Jack.
5.2.
Keep the Jack clean and lubricate all moving parts with lubricating oil on a regular basis.
5.3.
To check the oil level, fully lower the Jack. Remove filler plug (fig.3). The correct oil level should be approximately 5mm below the
filler opening. If oil level is low, fill as required. Pump unloaded jack 15 to 20 times to expel air and then refit plug.
