MAINTENANCE:
CAUTION
Turn engine OFF and disconnect battery before servicing equipment. Failure to comply
could result in minor personal injury, product damage, or property damage.
WEEKLY - AFTER EVERY 50 HOURS OF OPERATION:
1. Lubricate the bearings on the floor, the blower, and on each end of the feed roll shaft. Wipe
each bearing before lubrication to remove dirt and prevent overheating.
2. Blow out radiator fins with dry compressed air. Do not use a pressure washer, as this will
damage the radiator fins.
3. Remove and clean or replace air cleaner elements on the engine and rotary blower. To
clean elements, use clean compressed air.
4. Check the oil level in the rotary air valve gearbox. Add or replace if necessary.
5. Check the gear case on the blower (see Lubrication Chart, pages 18 and 19).
6. Check the tension on the floor conveyor chain. Adjust so the chain slats clear the bottom
pans on the return side by 1/2 in. (13 mm), by turning the jackscrews on each end of the
idler shaft. Adjust evenly, making sure the shaft does not shift sideways.
7. Check rotary air valve knife (or knives) for wear, chips, and clearance.
To change the knife (or knives), use the following:
DANGER
Knives have very sharp edges that can cause serious injury. Handle with care. Failure to
comply WILL result in severe personal injury or death.
A) Remove the five bolts that hold the knives and transition doors to the rotary air valve
knife shelves.
B) Remove the doors and knives.
C) Clean all dirt and debris from shelves.
D) Back out the two center jacking screws on each shelf.
E) Compare the replacement knife to the removed knife. If the new knife is wider, back
the two outside jacking screws out by at least that amount. Count the turns and
back both screws out evenly.
F) Lay the knife on the knife shelf. Ensure the knife is installed with the cutting angle
edge facing down, as shown in Figure 5. Loosely install the two outer, and the
middle knife mounting bolts. Tighten the mounting bolts enough to hold knife in
position, while still allowing it to be moved.
