into impeller.
11 Snow too heavy or wet or has other material
in it
11 Depending on ambient temperature, humidity levels, and overall climate conditions including actual snow
conditions, there may be no solution as snow may be too wet or compacted to move or throw. If snow is
filled with foreign material, damage to the snow thrower may result. Avoid snow with foreign materials.
12 Forward speed too fast while blowing snow,
