Before you start, make sure the snow is not wet or icy. Also, try not to clear snow in windy conditions, as this does not tend to work very well.
Set up the blower for maximum air concentration. This will help move heavier bits of snow and some ice.
Plug in the leaf blower with a GFCI-protected outdoor electrical cord, or plug a standard outdoor extension cord into a GFCI-protected outlet. GFCI protection is critical for electrical safety when working in damp or potentially wet conditions.
Walk out from your starting area and blow the snow away from you. If you have a walk-behind blower, start in the middle and clear the snow in overlapping strips. If you have a backpack or handheld blower, work away from your start point. like you do when blowing leaves. In either case, try not to walk on the snow to prevent compaction.
Once you have finished clearing the snow, dry your leaf blower before you put it away. Leaf blowers typically are not designed for wet conditions.
