7.1 Warnings
Standard hydraulic mineral oil should not exceed a temperature of
70°C during operation else it would damage the hydraulic system in
use. Maximum temperature for water glycol is 50°C.
Do NOT exceed the maximum working pressure that the cylinder is
designed for. When the external load can induce a higher pressure,
mount an additional pressure-relief valve (set at design pressure)
directly to the cylinder oil-port.

7.5 General information about accessories
Hypos
HYPOS (HYdrowa POsitioning System) is an integrated positioning system
which measures the length of the extending or retracting piston rod. This
system is mounted in the head of the cylinder. The system is easy to use,
because it is preinstalled and tested before the cylinder leaves the factory.
When operating the cylinder make sure that the speed of piston
rod doesn’t exceed 5 m/s. HYPOS works properly if the speed
remains under 5 m/s.
HYPOS can only be used in an area with temperatures between
-20°C and 100°C.
Mechanical end-switch
Mechanical end-switches have no difficulties in usage, but be careful with this
part it’s fragile.
