MAINTENANCE
CAUTION
Do not mix different kinds of hydraulic
fluid. Some fluids are not compatible and
may cause performance problems and
product damage.
CAUTION
Change the fluid at the beginning of each
plowing season. Failure to do this could
result in condensation buildup during the
non-plowing season.
