5.2 Cleaning/replacing the large surface−mounted silencer
Caution
Dirt in the large surface−mounted silencer can cause an
increase in pressure in the exhaust channel.
·
Clean the silencer insert if it is yellow/black or a dark
colour, or replace it by a new one.
·
Do not use TRI for cleaning, but benzine or paraffin.
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 and remove the screws in the fastening frame.
2. Remove the silencer insert from the end plate.
3. Replace the silencer insert or clean it.
4. Place the cleaned or the new silencer insert and the
fastening frame on the end plate.
5. Fasten the silencer insert only with the original screws
(see table).
