ATTENTION!
Braking force of the feed car makes up the braking force of wheels of the machine.
5.3. SERVICING OF PNEUMATIC SYSTEM
Within the scope of servicing of feed car one must verify the pneumatic system tightness, exercising special care of
all fittings. Tightness of the system must be checked at rated pressure of approximately 600 kPa (6,0 kg/cm
In case the piping, gaskets and other elements of the system are damaged, compressed air will get through the
damaged parts with characteristic fizzing or in case of small leakiness, in the form of air-bladders. Small leaks may
be detected by laying washing liquid on verified parts. Damaged pipes or gaskets, that are the reason of lack of
tightness, must be replaced with new ones. If the reason of lack of tightness is air coming out of servomotor – you
must regenerate servomotor.
You should remove condensation water from the tank on regular basis. For this purpose you should put the pin of
drain valve, located on the bottom of the tank, out. Compressed air will make to water flow outside. After releasing
the pin the valve should close itself automatically and stop air outflow from the tank.
You must screw the valve out and clean it thoroughly once a year, before winter season
