7. Maintenance
iMportant:
only fully qualified personnel should attempt maintenance or repair.
7.1.
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.
7.1.1.
lubricate the ram, the linkages and the saddle and pump mechanism with light oil.
7.1.2.
Grease the wheel bearings and axles.
7.1.3.
Keep all jack surfaces and warning labels clean.
7.1.4.
check and maintain the ram oil level (section 7.3).
7.2.
three monthly maintenance
7.2.1.
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.
7.3.
checking the oil level
7.3.1.
fully retract the ram by turning the release valve counter-clockwise.
7.3.2.
With the jack in the level position, remove the oil filler plug.
7.3.3.
the oil should be level with the bottom of the oil filler hole. if it is not, top up with clean hydraulic jack oil.
7.3.4.
replace the oil filler plug and check the jack operation.
7.3.5.
Purge air from the hydraulic unit as required. refer to section 5.
note:
Always store the jack in the fully lowered position. this will protect critical areas from excessive corrosion.
