Wichtig!
Daily drain the air reservoir
1. Pull the drain valve (Fig. 141/3) via the ring
to the side until no water will run out of the
air reservoir (Fig. 141/1) any more.
→
Water runs out of the drain valve (Fig.
141/3).
2. Remove the drain valve (Fig. 141/3) from
the air reservoir and clean the air reservoir
in case dirt is noted.
Inspection advice for two circuit service brake system
1.
Leak test
1. Check all connections, tubes, hose and bolted connections for
tightness.
2. Remedy leaks.
3. Remedy rubbing points on tubes and hoses.
4. Replace porous and defective hoses.
5. The two circuit service brake system is regarded as tight, when
the pressure drop is not more than 0.15 bar within 10 minutes.
6. Tighten the leaking points or replace leaking valves.
2. Checking the pressure in the air reservoir
1. Connect a pressure gauge with the inspection port of the air
reservoir.
Required value 6,0 to 8,1
+ 0,2
bar
3. Checking the brake cylinder pressure
1. Connect the pressure gauge with the inspection port of the
brake cylinder.
Required values: brake not applied 0,0 bar
4. Visual inspection of the brake cylinders
1. Check the dust collars or the bellows for damage.
2. Replace defective parts.
5. Joints on brake valves, brake cylinders and brake linkages
Ensure the smooth running of all joints on brake valves, brake cylin-
ders and brake linkages, if necessary grease or slightly apply oil.
