Maintenance
Drain the air reservoir every day during op-
¾
eration.
Air vessel with drain valve
Clean the pipe filter in the coupling heads
¾
whenever required, but at least once every
year.
To ensure the function of the valves, anti-
¾
freeze should be added to the compressed air.
Follow the operating instructions of the tractor!
The coupling heads should be closed with
¾
lids to protect against damage caused by
moisture.
Operate the brake several times after wash-
¾
ing the machine to cause the brake drum to
become hot and any water in the drum to
evaporate. This will prevent damage to the
brake during extended idle times.
