WARNING / CAUTION!
Always keep a safe distance from the hydraulic cylinder when you pressurise it,
particularly when starting up after positioning the equipment!
CAUTION!
Always check, before each start-up, that the hydraulic connections are correctly
made and that they are functioning perfectly.
Incorrect connections or defective couplings can cause a safety valve to
respond (e.g. on double acting cylinders on the piston rod side or on hoses
with safety Quick-disconnect connectors on the male coupling!)
When using several pistons at the same time, you should distribute the load as evenly
as possible over all the cylinders.

When using several pistons at the same time, you should lift the load as evenly as
possible using all the cylinders.
