OPERATING TIPS
1. Snow is best removed as soon as possible after snow fall.
2. To clear an area property run the Sno-Thro in an overlapp
ing series of paths. For large areas start in the middle and
blow snow to each side so it doesn’t have to be moved
more than once.
3. Snow should be discharged with the direction of wind
whenever possible. Do not blow snow any higher than
necessary.
4. Chemicals used to melt ice and snow may damage the
finish of your Sno-Thro. When possible, wipe the Sno-Thro
clean with a rag (use of automotive wiper washer fluid may
be applied) to remove residue.
