Section 6 – Maintenance
4. Install the new cartridge. Slide the new cartridge onto the pole.
Align holes on pole and cartridge then install bolts, washers and
nuts to lock in cartridge (Fig. 4).
5. Reset the correct blade tension. Refer to the chart for the spring
length/kPa required for the belt width. For PST lightly pull the
pivot arm toward the end of the torque arm slot nearest the pole
and turn the adjusting nuts until the required spring length is
achieved (Fig. 5). Tighten jam nut. NOTE: The chart is also on the
cleaner’s pivot shaft bracket for future reference for retensioning
maintenance.
Test run the cleaner. Run the conveyor for at least 15 minutes and inspect the cleaning performance. Check the spring
length for proper tensioning. Make adjustments as necessary.
3. Change blades on cartridge. Be sure to install all new blades to
ensure even cleaning. To remove blades, unlock blade stop, remove
handle and loosen cartridge expansion bolts. Clean cartridge
before installing new blades. Install new blades then tighten
cartridge expansion bolts and reinstall blade stop handle (Fig. 3).
