Operation

19

In wet or slushy conditions, clogging of the discharge
chute will be reduced by maintaining maximum
engine speed and by not overloading the engine.

In some snow and cold weather conditions, some
controls and moving parts may freeze. Therefore,
when any control becomes hard to operate, stop the
machine and wait for all moving parts to stop; then
check all parts for freeze up. DO NOT USE
EXCESSIVE FORCE AND TRY TO OPERATE
THE CONTROLS WHEN FROZEN. Free all
controls and moving parts before operating.

Use low range (on the high–low range lever) for best
performance and smoothest operation.
