6.1
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.
6.1.1 Lubricate the ram, the linkages and the saddle and pump
mechanism with light oil.
6.1.2
Grease the wheel bearing and axles.
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 Monthly Maintenance
6.2.1
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.
6.3
Checking the Oil Level
6.3.1
Fully retract the ram by turning the release valve
counter-clockwise.
6.3.2
Undo the four top plate retaining screws and remove the top
plate.
6.3.3
With the jack in the level position, remove the oil filler plug.
6.3.4
The oil should be level with the bottom of the oil filler hole.
If it is not top up with clean hydraulic jack oil. (Sealey Part
No: HJO500MLS or HJO5LS)
6.3.5 Replace the oil filler plug (C) and check the jack operation.
6.3.6
Purge air from the hydraulic unit as required. Refer to
Section 4.
6.3.7 Replace the top plate and secure with the four screws.
NOTE: Always store the jack in the fully lowered position. This
will protect critical areas from excessive corrosion.
