OPERATING INSTRUCTIONS
1. IMPORTANT! Prior to its first use, make sure to check for proper hydraulic oil
level in the Bottle Jack. Then thoroughly test the Bottle Jack for proper op-
eration prior to its actual use. If the Bottle Jack appears
not
to be working
properly, it may be necessary to
bleed
its hydraulic system of excess air. To d o
so, remove the Oil Filler Plug. Assemble the complete Handle Assembly and lower
the saddle of the jack fully. Insert the slot on the lower portion of the Handle Assem-
bly over the Valve Release Screw. Turn the Handle Assembly
clockwise
to close the
Valve Release Screw. Insert the Handle Assembly into the Plunger/Fulcrum As-
sembly. Apply pressure to the Saddle, and pump the Handle Assembly slowly several
times. The trapped air is pressurized and will be audible when released in this
manner. Once bled of air check the Oil Fill Hole and, if necessary, top off the Oil Fill
Hole with hydraulic oil. Then, replace the Oil Filler Plug. Turn the Handle Assembly
counterclockwise
slowly to completely lower the Jack. Test the Jack several times
for proper operation before attempting to lift a load. If, after purging, the Jack still
does
not
appear to be working properly, do not use the Jack until it has been
repaired by a qualified service technician. (See Diagrams, below.)
NOTE: There may be some slight differences in the
appearance
of the various jacks,
