Operation
16. Belt Installation:
For Small Decks:
A. Slip the belt over the impeller sheave on the
blower.
Note: It may be easier to install the belt if
the belt guide is temporarily shifted to one
side or temporarily removed. Either loosen
or remove both nuts on the top and bottom
of the belt guide. Once the belt is installed
on the impeller sheave, reinstall the belt guide
and tighten all hardware.
