General Operating Instructions
This is an air-actuated hydraulic bottle jack. The air motor
is air pressure activated and drives the hydraulic jack.
In the event no air pressure is available, a standard
hydraulic piston assembly is provided for hand jacking.
Note: Safety shutoff prevents lifting
in excess of rated load.
1. Position the Jack on a solid level surface
that can withstand the weight of the jack
and the load which will be lifted.
2. Be sure the load is balanced on the jack.
Properly rated jack stands (not included) positioned
under the weight provide a good safety precaution
against the possibility of the load toppling.
3. Be sure that the jack is positioned at a proper lift
point on the item to be lifted. Using appropriate
lift points avoid possible damage to the item.
4. Rotate the Screw Extension on the Ram until it
contacts the underside of the load to be lifted.
Screwing counterclockwise raises the extension,
screwing clockwise lowers the extension.
5. Engage the notch on the end of the Jack Handle
onto the Release Valve. Turn the Release Valve
slightly clockwise to ensure that the valve is
closed. The jack will not lift if the valve is open.
6. Operation
a. Pneumatic Operation: Connect a pressurized
air source to the Air Inlet then squeeze the
Throttle Lever on the Air Valve to raise the load.
b. Manual Operation: Insert the end
of the Jack Handle into the Handle
Bracket and pump up and down.
7. Support the load using jack stands (not included)
or other means to support the weight.
Do not leave the load on the jack for an
extended period of time. Damage to the jack
or personal or property injury may result.
8. To lower the item, first use the Jack to lift the
item slightly and remove the jack stands.
9. Engage notches in the end of the Jack Handle
onto the Release Valve. Turn the valve
approximately 1/4 turn counterclockwise to lower
the load. When the load is lowered, turn the
Release Valve clockwise to stop the motion.
10. If an automatic oiler is not used, add a few
drops of Pneumatic Tool Oil to the airline
connection before use. Add a few drops
more after each hour of continual use.
11. If the tool requires more force to accomplish
the task, verify that the tool receives sufficient,
unobstructed airflow (CFM) and increase the
pressure (PSI) output of the regulator up to the
maximum air pressure rating of this tool.
cAUTION! TO pREVENT INJURy FROM
TOOL OR AccESSORy FAILURE:
Do not exceed the tool's
maximum air pressure rating.
If the tool still does not have sufficient force
at maximum pressure and sufficient airflow,
then a larger tool may be required.
12. To prevent accidents, turn off the tool, detach
the air supply, safely discharge any residual air
pressure in the tool, and release the throttle and/
or turn the switch to its off position after use.
Clean external surfaces of the tool with clean,
dry cloth, and apply a thin coat of tool oil.
Then store the tool indoors out of children's reach.
