Assembling the extension riser
For larger coverage heights an extension riser is needed. Insert the extension riser into the tank dome,
(soft soap is needed) then into the highest groove of the extension riser inserted the profile seal and soap
generously. Afterwards push the telescopic dome shaft into the extension riser and adjust it to the
planned area surface.
1 Extension Riser = max. earth-cover 955 mm (with standard lid and shaft)
respectively 1055 mm (with vehicle lid and shaft)

Inspection and servicing
The entire system must be checked for leaks, cleanliness and stability at least every three months.
The entire system should be serviced at intervals of approx. 5 years. In this case, all parts of the system
must be cleaned and their function checked. Servicing should be carried out as follows:
Drain the tank completely
Clean surfaces and internal parts with water
Remove all dirt from the tank
Check that all internal parts are firmly seated.
