Monthly Maintenance
lubrication is critical to jacks, since they support heavy
loads. Any restriction due to dirt or rust can cause either
slow jack movement, or extremely rapid jerks, causing
damage to the internal components. to keep the jack well
lubricated, carry out the following steps:
5.1.1.
lubricate the ram, the linkages, the saddle and pump
mechanism with light oil.
5.1.2.
Grease the lifting arm, wheel bearings and axles.
5.1.3.
Keep all jack surfaces and warning labels clean.
5.1.4.
check and maintain the ram oil level (section 5.3).
5.2.
Three Monthly Maintenance
5.2.1.
At three monthly intervals, check the ram for any signs of
rust or corrosion. clean the ram as required and wipe with
an oil cloth.
5.3.
checking the oil Level
5.3.1.
fully retract the ram by turning the release valve control
knob counter-clockwise.
5.3.2.
With the jack in the level position, carefully remove the top
cover.
5.3.3.
remove the oil filler plug.
5.3.4.
the oil should be level with the bottom of the oil filler hole.
