5.3.1 Cleaning the large surface−mounted silencer
Caution
Dirt in the large surface−mounted silencer can cause an
increase in pressure in exhaust channels 3 and 5.
·
Clean the silencer insert if it is yellow/black or a dark
colour, or replace it by a new insert.
·
Do not use
TRI
for cleaning, but benzine or paraffin.
·
Observe the safety regulations for easily inflammable
cleaning agents.
In this way you can ensure that the large surface−mounted
silencer functions correctly and that the valves operate
correctly.
Proceed as follows:
1. Loosen the 6 fastening screws of the surface−mounted
silencer and remove it from the basis components.
2. Clean the surface−mounted silencer with benzine or paraf
fin.
3. Check the seal between the basis component and the
surface−mounted silencer for damage. Replace the seal if
it is damaged.
4. Fasten the silencer only with the original screws. Tighten
the screws in diagonally opposite sequence
with 1.0 Nm.
