one/both direction(s)
NOTICE!
On multiple helm applications, there is a possibility to enter a slow
freewheel situation if 1–helm is turned 1–direction and then the opposite
helm is slowly turned the opposite direction. This is normal and can be
stopped by performing a quick, partial turn of the wheel to fully close a
hydraulic valve.
CAUTION!
A system that is not responding must be diagnosed and corrected
prior to use.
WARNING!
Dometic does not recommend the disassembly of any helm pump.
Contact an Authorized Service Center, or, replace helm pump.
