OPERATION
Place the Flat Bottom Jack on a solid, level surface capable of bearing the combined
weight of the tool and load. Due to the variety of applications possible for this jack,
proper hardware suited for the application must be supplied by the user and proper
mounting procedures must be followed by the installer. If you are not familiar with
this type of work or have any doubt about your capability to safely install this jack,
have a qualified technician install the jack for you. To secure the top of the Hydraulic
Jack, slide a pin (not included) through the product and Ram (13). Make sure the
pin’s diameter is a push fit with just enough clearance so that it can move freely.
The pin should be held in place with appropriate clips or hardened cotter pins (not
included)..
Note: WARNING! The Pin must be rated to support at least 8 tons (~16,000
pounds) of pressure. (See Figure A.)
Insert the Handle (21) into the Handle Bracket (31).
Raising and Lowering:
To raise the Flat Bottom Jack turn the Release Valve (4) clockwise until the valve
is tightly closed. Pump the Handle (21) to raise the Jack. Continue to pump the
Handle (21) until the Flat Bottom is at the desired height.
To lower the Jack, first verify that the area under the object is clear, then turn the
Release Valve (4) counterclockwise. This will release pressure in the Jack and
cause the Jack to lower.
