Lubrication is critical to jacks as they support heavy
loads. Any restriction due to dirt, rust or corrosion can cause
either slow movement or rapid jerks damaging the internal
components. The following steps are designed to keep the
jack maintained and operational:
1. Open the release valve by turning the handle knob counter
clockwise and push the ram to its lowest position
2. Remove the filler plug.
3. Fill with clean hydraulic jack oil. Do not use hydraulic brake
fluid.
4. Reinstall the filler plug.
Add lubrication to all moving parts as needed.
Every 6 months.
Carry out a thorough inspection for service-
ability of component parts Visually inspect for oil leaks (only
a slight oil seepage is permissible). If a leak is found, take the
jack out of service and consult with SGS Engineering.
Annually.
Check the ram oil level as follows:
1. Ensure the ram is fully retracted by turning the knob fully
anticlockwise.
2. Remove the cover plate, located at the base of the handle
housing, to gain access the ram, then remove the ram filler
plug.
3. Lift the jack so that it is vertical, resting on its front wheels
and check the oil level. It should be level with the bottom
of the oil filler hole. If necessary, top up with Hydraulic oil.
4. Replace filler plug and purge system of air (see page 6).
