Maintenance
Periodically release the condensation from the air filter. Replace the hydraulic oil
every 1500 hours or whenever the oil is polluted.
Warning
: Remember that repair work can only be made when pneumatic and
hydraulic pressure has been released and you are sure that no pressure remains in
the circuit.
Delivery of the pump
Transport
All the material shipped, including the detached parts, has been thoroughly
checked before being consigned to the forwarding agent. The pump is shipped in
double corrugated cardboard packaging which assures protection of the
product.
Unpacking
On receipt of the product, open the packaging and remove the pump. Take care
not to damage any part of the pump. Make an initial check on the pump for
damage in transit. In case of damage or if in doubt, do not use the pump and
contact Hydronic Corporation or your distributor. The packaging [plastic bags,
expanded polystyrene, nails, screws, wood, etc.] must not be left within reach of
children since they are potential source of danger. Be sure to dispose of pollutant
or non-biodegradable materials in the correct way. Materials must be disposed of
in accordance with the local, national and ecological laws in force.
