4.2
Check oil level in reservoir before operating the jack
4.2.1
Open release valve with the handle (not more than two counter-clockwise
turns) and press down on the head-toe attachment to ensure the piston is
fully down.
4.2.2
Remove the oil filler plug.
4.2.3
The oil should be level with the bottom of the filler hole. Adjust level as
necessary and replace plug.
4.3
Remove air from the system – Air can accumulate in the hydraulic system during the
initial setup or after prolonged use, causing the cylinder to respond slowly or in an
unstable manner. Should removal of air from the jack be required, please follow the
steps in 6.2 – Bleeding Air from the System in the Maintenance Section.
4.4
Lubrication - Oil the pivots of the manual pump mechanism.

Operation
IMPORTANT:
Do NOT
lift a load on the end of the toe. Fully engage the load with the toe and
where practical ensure that the top of the vertical face “head-toe” attachment is
also engaged with the load
When lifting by the toe, wedge the head of the jack on the load to avoid bending
the column
5.1
Raising the Jack
5.1.1
Close the release valve (clockwise) with the jacking handle.
5.1.2
Position the jack so that the toe or head is under the load point. Do not use
the handle in the release valve to move the jack. Damage will occur.
5.1.3
Pump the jacking lever in an up and down motion.
5.2
Lowering the Jack
5.2.1
Check beneath the load for any obstructions and remove any mechanical
supports.
5.2.2
Slowly open the release valve (counter clockwise) with handle. Control the
rate of descent by smoothly opening or closing the valve.
5.2.3
To stop the jack from lowering the load, close the release valve (clockwise).
5.2.4
Note: The release valve should not be closed abruptly (except in an
emergency) since this shock loads the hydraulic system.
5.2.5
After use, the jack should be stored with the load piston and pump piston
both fully retracted.
