MAINTENANCE

IMPORTANT: Only fully qualified personnel should attempt maintenance or repair. Jacks shall be maintained and repaired under the manufacturer’s instructions. Such maintenance and repair shall be carried out by qualified persons. No modifications shall be carried out which adversely affect the compliance of the jack with the standard. Check the state of the markings and that the markings remain as the initial one.
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:
Lubricate the ram, the linkages and the saddle and pump mechanism with light oil.
Grease the wheel bearings and axles.
Lubricate the castors with light oil.
Keep all jack surfaces and warning labels clean.
Check and maintain the ram oil level.

THREE MONTHLY MAINTENANCE

At three monthly intervals, check the ram for any signs of rust or corrosion. Clean the ram as required and wipe with an oiled cloth.

CHECKING OIL LEVEL

Fully retract the ram by turning the release valve counter-clockwise.
With the jack in a level position, remove the oil filler plug (fig.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. (Sealey Part No: HJO500MLS or HJO5LS)
Replace the oil filler plug and check the jack operation.
Purge air from the hydraulic unit as required.

NOTE: Always store the jack in the fully lowered position. This will protect critical areas from excessive corrosion.
