Q I SMELL BURNING RUBBER WHEN I USE MY Sentria™ SYSTEM
WHAT SHOULD I DO?
A 1. Check to see if the Brash Roll is turning when the Sentria system is running. If not, then
the Brush Roll may be stalled due to threads around the ends. Remove Brush Roll and
make sure it rotates freely at both ends. (See page 54.)
2. The belt may not be fully engaged (or disengaged). Make sure the green arrows or red
arrows on the Belt Lifter (20) match up fully.
3. If a slipping belt has deposited a black residue on the Motor Shaft (23), remove it gently
using steel wool or sandpaper and replace the belt.
