13.2 REGULAR INSPECTION
L
DANGER! Disconnect the electric current supply to the machine by turning the
main switch into “0” position and close the compressed air, oxygen and propane
supplies before proceeding to the following maintenance routine - unintentional
starting of the machine may cause a serious accident or damages to property.
The cylinders of the frame
Check the fixing screws of the ball joints located on the ends of the piston rods of the
cylinders. Tighten if necessary.
Forming tool
Check that the bearings of the forming tool are not worn. The forming pin must turn
easily when moved by hand. The radial play may not be more than 0.2mm and the axial
play may not exceed 0.4mm. If necessary, change the bearings.
Limit switches
Check that the switches S33 and S34 trip just before the movement of the heating burner
arm reaches the extreme limits. Check that the B3 and B4 micro switches actuate just
before the end of the cylinder stroke. Adjust if necessary.
Check the correct function at the right moment of the safety switches of the protective
hood and of the service door of the burner. The machine should stop when opening
these doors and covers and it should be impossible to restart the machine when they are
open.
The hydraulic system
See the separate instructions for the hydraulics.
The heating unit
The tightness of the gas system joints and couplings should be checked daily. The
membranes of the valves must be clean at all times. Even the smallest dirt particle may
cause a gas leakage, which can be perceived by an abnormal function of the burner when
lighting and extinguishing it. Tighten the leaking joints or replace the worn hoses and
other damaged parts by new ones.
