HOW TO MAINTAIN
The instructions in this booklet serve as a guide to routine maintenance. To
avoid unnecessary service calls, check the dust cup, belt, and brushroll often.
Brushroll
The brushroll turns as it sweeps and combs the carpet nap. Remove hair
and threads from the brushroll so it continues brushing the carpet. To
maintain the most efficient cleaning, the bristles must touch the carpet.
To test the bristle length, hold a ruler against the underneath side of the
cleaner. If the bristles no longer touch the ruler, replace the brushroll.
Brushroll Belt
Brushroll Performance Window (FIG. 19). To check condition of belt
watch to see if white dots on belt are moving through the performance
window (FIG. 19a). This indicates the brushroll is turning.
The brushroll belt turns the brushroll to agitate, sweep, and comb the carpet
nap. Check the belt regularly to be sure it is in good condition. Replace the
belt if it stretches, cracks or loses tension. Cut away any hair or threads
wound around the brushroll or the belt pulley because the buildup could
cause the belt to rotate unevenly.
