3m fan guide
If it is found that the fan speed cannot be adjusted finely enough due to the increment being too large on
the tractor spool, there is a needle value located at the bulk head end of the hydraulic pipe that feeds the
fan.
The adjustment should be carried out by, setting the fan speed slightly higher than desired and then
reducing the flow of oil by rotating the needle valve clockwise.
If the tractor spool is providing the correct oil flow for the desired fan speed then the needle valve should
be adjusted so that it is fully open.
3m tramline system
The Sumo DTS is unique in that the drill does not have any tramline markers as such, the coulters that are
blocked off are lifted.
This system works by the way of a 3 way solenoid diverter, and the hydraulic feed form the bout markers.
When the bout marker is pressured in to work the spool should be left pumping for an extra 5 seconds to
allow for the two tramline coulters to be raised. When the marker is retracted the coulters will resume
normal work.
