The parking brake works with spring accumula-
tor brake cylinders.
With the air reservoirs fully filled the brake can
also be released manually and the seed wagon
can be moved without braking function.
However, the machine must be hitched
up beforehand or secured against rolling
by other suitable means.
Driving without brake on public roads is
prohibited.
Releasing the brake
Press the service brake button (2) up; this re
-
leases the service brake.
Then press the parking brake button (1) up to
release the parking brake.
Before parking the machine pull the park-
ing brake button down again to apply the
parking brake.
Maintenance
¾
Drain the air reservoir every day during op-
eration.
¾
Clean the line filter as required, but at least
once every year.
¾
Check the brake lining for wear every year
and renew as required.
Pipe filter
End of the season
For functional safety of the valves, antifreeze
agent should be mixed to the compressed air
(follow the operating instructions of the tractor
manufacturer).
This agent maintains the elasticity of the seals
and reduces rust deposits in lines and reservoirs.
As a preventive measure against damage
caused by moisture, the pneumatic brake hose
couplings can be covered with plastic lids or a
plastic bag.
Emergency releasing facility
In events of emergency the spring accumulator
brake cylinders can be manually released.
For this purpose back out the screw on the
spring accumulator housing, until the brake is
released.
