FRICTION FACING INSPECTION
Visually inspect the Friction Facings after every forty hours of
operation. Replace the friction facings when the remaining
material is 5/16" thick. Use a scale to measure the thickness
on the DFC-2200.
The DFC-1650 has steps in the friction facing which
indicate 5/16" thickness. When the steps are no longer
visible, the facings need to be replaced (See Figure 7).
