Lowering the Jack
Caution: Avoid rapid descent of the load by turning the Release Valve slowly.

Slowly and carefully lower the load by turning the Release Valve counterclockwise in very small

INSPECTION, MAINTENANCE, AND CLEANING
Before each use, inspect the general condition of the Bottle Jack. Check for broken, cracked,
or bent parts, loose or missing parts, and any condition that may affect the proper operation
of the product. If a problem occurs, have the problem corrected before further use. Do not
use damaged equipment.
Before each use, make sure to thoroughly test the Bottle Jack for proper operation prior
to its actual use. If the Bottle Jack appears not to be working properly, it may be neces-
sary to bleed its hydraulic system of excess air. Refer to pages four and five for complete
instructions on bleeding the system.
Change the hydraulic oil at least once every three years. To do so, with the Bottle Jack
fully lowered, remove the Oil Filler Plug on the side of the Housing. Tip the Bottle Jack to allow
the old hydraulic oil to drain out of the Housing completely, and dispose of the old hydraulic oil
in accordance with local regulations. With the Bottle Jack upright, completely fill the Housing
with a high quality hydraulic oil (not included) until the oil just begins to run out of the Oil Fill
Hole. Then, reinstall the Oil Filler Plug.
When cleaning, use a clean cloth with a detergent or mild solvent. Then, store the Bottle Jack
in a safe, dry location out of reach of children and other non-authorized people.
WARNING! All maintenance, service, or repairs not listed in this manual are only to be
