Tennant M20 kit installation instructions

Tennant's instruction bulletins for M20 kits (60 bulletins, 435 pages): what each kit is for, what it fits, the safety warnings, the parts with prices, and every installation page with its text.‌‌​⁠‍‍‌​‌​‍‌⁠‌⁠​⁠‌‌⁠​​​​​​​​​​​‌​‍‌​​‌⁠‍‌‌⁠‌​‍​⁠⁠‌‌​‍​‌​​​‍⁠

Tennant part numbers changed. In November 2025 Tennant renumbered all of its parts. Every line here shows the new number and the old one, so an old printed manual still works: look up the old number and it takes you to the new one.

From Tennant's M20 instruction bulletins (2006–2024), 435 pages.
