2. Safety
2�1 Warnings
• Use only accessories that can safely operate at the maximum pump pressure.
• Once you have assembled the pump, check it over thoroughly to ensure that it is safe and
also that it matches the accessories that are going to be used with it.
• Never connect accessories for moving the pump.
• Never exceed the maximum pressure stated on the pump.
2�2 Safety risks
• Leakages can occur if the accessories are not connected properly. Always examine the
accessories before the system is put under pressure.
• Never use hands or fingers when probing at, or around oil leaks! This could lead to the
hydraulic oil being injected under the skin, leading to the potential loss of the hand or
finger in question!
• Fill the system with hydraulic oil only when all the cylinders are fully retracted. Overfilling
can lead to injury when the pressure builds up in the reservoir.
2�3 Safety provisions
• The pumps are fitted with internal safety valves that open as soon as the maximum
pressure is reached. The hydraulic oil passes through the safety valves and back into the
reservoir. Never adjust the settings of the safety valves.
• The pump reservoir is fitted with a bleeder for preventing pressure or vacuum building
up in the reservoir.
2�4 Inadvisable usage
• The pump should only be used with suitable accessories. Check all components to
confirm whether they are suitable for working at maximum pump pressure.
2.5 Safety measures (to be applied by the user)
• After assembling all the components and accessories, assess whether the entire system
is safe to operate.
• Always check everything each time before using. If any of the accessories are damaged,
they must be replaced or repaired before using by skilled personnel (or the supplier).
Damaged hoses must be replaced immediately.
