1 Safety
Handling the valves/ machines
WARNING
Carrying-out work on the valves/ machine during
operation
Carrying-out any work during operation, such as e.g.,
hydraulic connection of components, can cause un-
controlled sequences of motions, malfunction, and
others, and thus may result in fatalities, serious per-
sonal injuries and serious damage to property.
 During operation, do not carry out any work on the
valves/ machine.
 Before working on the valves/ machine, stop the
machine and switch off the supply voltage.
 Secure the machine against restarting. Examples
of suitable securing measures:
• Lock the main command device and remove
the key.
• Attach a warning sign to the master switch.
WARNING
Hydraulic fluid squirting out
Hydraulic fluid squirting out under high pressure can
cause serious personal injuries, burns and fires.
 Before working on the valves/machine, depres-
surize all hydraulic lines and accumulators.
 When mouting the valves, observe the specifica-
tion of the installation screws and the mounting
pattern and ensure the presence, elasticity, integ-
rity and correct seating of the O-rings.
 Observe the maximum operating pressure.
WARNING
Wrong handling
Wrong handling of the valve, tools or accessories
may result in fatalities, serious personal injuries and
serious damage to property.
 Only properly qualified and authorized users may
work with and on the valves.
 When working with and on the valves/machine,
observe the machine manufacturer's notes and in-
structions.
CAUTION
Misuse of the connectors, mating connectors
(plugs) and connection cables
Misuse, such as e.g., use as foot hold or transport fix-
ture, can cause damage and thus may result in per-
sonal injuries as well as further damage to property.
 Use the connectors, mating connectors and con-
nection cables exclusively for the connection of
the valve.

Occupational safety and health
CAUTION
Falling objects
Falling objects, such as e.g., valves, tools or acces-
sories, may result in personal injuries and damage to
property.
 Wear suitable safety equipment, such as e.g.,
safety shoes or helmet.
CAUTION
Hot surfaces of valves and hydraulic lines
Valves and hydraulic lines can become very hot dur-
ing operation. Contact may result in burns.
 Wear suitable safety equipment, such as e.g.,
work gloves.
CAUTION
Noise emission
Depending on the application, significant levels of
noise can be generated when the valves are oper-
ated. This may result in hearing damage.
 Wear suitable safety equipment, such as e.g., ear
protection.
CAUTION
Skin contact with hydraulic fluid
Skin contact with hydraulic fluid may result in per-
sonal injuries.
 Observe the safety regulations applicable to the
hydraulic fluid used.
 Wear suitable safety equipment, such as e.g.,
work gloves.

Class of cleanliness: According to ISO 4406:1999 at least
class 18/15/12; for longer life, class 17/14/11 recommended.
The cleanliness of the hydraulic fluid greatly influences the
functional safety and the wear and tear. In order to avoid mal-
functions and increased wear and tear, we recommend filtrat-
ing the hydraulic fluid accordingly.
Flushing instruction: Use of flushing plates or flushing valves
according to the machine manufacturer's instructions.
