Attention
Use always rubber grommets to protect air tubes and to prevent that
dust and water enters the cabin.
For trouble free life of the entire pneumatic system the air system
must be free from water.
The air exhaust connection must be brought outside the cabin to
prevent air entering the cabin, which gives the following
disadvantages:
1 noise
2 blown up sand and dust
3 when alcohol is used to prevent the pneumatic system against
frost the alcohol vapour will enter the cabin.
The air control should be mounted in such a way that:
1 it is easy to reach by the operator.
2 it is no obstacle when entering or leaving the cabin.
3 it is clear from any moving parts such as drivers seat and closed
door.
Make sure that air tubes:
1 are not too close to sharp objects.
2 are clear from moving parts.
3 are clear from exhaust and compressor lines.
4 can not get kinked.
5 are not too long.
