3 - SAFETY

Observe all the following safety rules. They are of the maximum importance for your own safety and the safety of others. In addition to
the indications in this chapter, observe also the prescriptions in all other sections of the manual.
DO NOT TAMPER WITH THE PROTECTIONS AND SAFETY DEVICES AND DO NOT MODIFY THE PUMP IN ANY WAY TO AVOID
CREATING POTENTIALLY HAZARDOUS SITUATIONS FOR WHICH THE OPERATOR OR THE SERVICE TECHNICIAN IS UNPRE-
PARED.
REMOVING OR TAMPERING WITH ANY OF THE SAFETY DEVICES ON THE PUMP AUTOMATICALLY INVALIDATES THE WAR-
RANTY AND ABSOLVES THE MANUFACTURER FROM ALL LIABILITY.
● The pump and the machine on which the pump is installed must be used exclusively by people over 18 years of age who have read
this manual and have a thorough knowledge of the machine and the pump.
● The pump may be used by people over the age of 16 provided they are supervised by an adult.
● Keep the pump well clear of heat sources, naked fl ames and sparks. Maximum operating temperature of the pump is 50° C.
● The pump may be operated with hands and feet, as long as you only press the "PUMP" and "RELEASE" zones indicated on the
pedal board.
● Work clothes must be close fi tting and buttoned up. Wear the protective clothing stipulated in the place where the pump is installed.
● Do not attempt to operate the pump by standing on the treadle, use only light foot pressure to operate the pump mechanism.
● Do not arbitrarily move the pump to different locations. The pump must be used in the position designated by the manufacturer of
the machine to which it is connected.
● When connecting the pump follow the prescriptions in chapter 5 "Installation and start-up" and always use certifi ed hoses and couplings.
For the choice of hoses and coupling, as well as hydraulic cylinders, remember that these components must be fi t to safely
support the max. pump pressure.
● Before operating the pump, ensure that all connections with pipes are clamped with appropriate tools. Do not tighten exces-
sively. Connections need to be clamped safely only and without leakage. Excessive tightening may cause an early thread
breakage or the breakage of high-pressure systems already with pressures lower than the capacities declared.
● Do not exceed the hydraulic pressure indicated on the pump label and do not tamper with the internal safety valve. Working with a
higher pressure than the stated capacity may cause damage to persons or objects.
● The work area must be kept clear of obstructions so that the pump can be operated in safe conditions.
Pay attention to falling objects which could strike the pump treadle and set the pump into operation.
● The work area must be kept clean and the fl oor must bear no traces of oil, grease or any other slippery or corrosive substances.
● If it were necessary to disconnect the air supply hose or the hydraulic oil hose, ensure that there is no pressure by disconnecting the
pneumatic power supply and by draining the hydraulic system.
● If a hydraulic pipe breaks or needs to be disconnected, immediately cut the supply to the pump and operate the RELEASE control
valve twice in order to release all pressure. Never try to grasp with your hands a leaking pipe under pressure. The power of hydraulic
liquid jets under pressure may cause serious damage.
● Do not expose the pipe to potential dangers, such as: fi re, extreme hot or cold temperatures, cutting surfaces or heavy weights. Do
not twist, turn, fold or bend the pipe to an extent that the oil fl ow in the pipe blocks or decreases. As one of these conditions may
cause damage to persons or objects, periodically inspect the pipe.
● Do not use the pipe to remove the equipment connected to it. This kind of stress may cause damage to the pipe, as well as persons
or objects.
● WARNING: the mechanical features of the pipe and the seal fi ttings must be compatible with the hydraulic liquid used and
must be fi t to safely support the max. pump pressure.
The pipes must not come into contact with corrosive substances. Never paint pipes or fi ttings: the deterioration due to corrosion may
damage their effi ciency causing unexpected breaks and damage to persons or objects.
If the pipes are uncovered and the operator is nearby them, they should be inserted into appropriate sheaths they have to
be fi xed in order to protect also the fi ttings. In event of break, the sheath prevents oil jets under pressure.
● If the pump develops a fault, do not attempt to repair it unassisted. Disconnect the compressed air supply, switch off the
machine to which the pump is connected and call a maintenance technician.
● Before restoring the oil level, ensure that the connected cylinders are in a pulled-back position.
The oil volume that is discharged into the tank from the cylinders when are retracted, must bring the oil to the maximum level allowed.
Excessive fi lling or topping up, without taking this factor into account, may cause the exceeding of the tank capacity, put the tank
even under pressure and result in breaks with damage and consequent risks to persons.
● When the pump is not being used and before interrupting any hydraulic connection or working on the system in any way, turn off and
disconnect the pneumatic supply.
