11.0 MAINTENANCE & SERVICE
1. Check the tank straps to make sure they stay tight so the tank does not
rotate in the bracket.
2. The system should be fl ushed with clean water if the foam marker is
not going to be used for a period of time.
3. If a polyethylene line has become cut or pinched, line menders
(#23212303 8mm and #23214603 10mm) can be used to make re-
pairs.
4. Make sure that all electrical connections stay clean and free of corro-
sion.

oughly with clean water to restore maximum performance to the Foam
Marker.
6. Clean the tank fi lter every 50 hours of operation.
