and move the shaft towards the frame so belts can be
removed.

to within 1/16". If not adjust pulleys.

with 10 lb. force applied at the center of the span.
Make sure the jack shaft is aligned parallel to the
rotor shaft before tightening the pillow block bolts.

2. Check air pressure in tire every 10 hours. Fill to
recommended pressure on tire sidewall.
3. Check and repack wheel bearings with grease every
year.
5.12 ADDITIONAL SERVICE AND
MAINTENACE TIPS
1. Service engine according to engine owners manual.
2. Every 10 hours of operation, all bolts and other
fasteners should be checked for correct torque.
3. The PTO model has 2 greasable bearings on the rotor
shaft. There are also two greasable bearings on the
main jack shaft under the small belt guard. These
bearings need only to be greased once per year under
normal working conditions. Be carefull not to damage
seals on the bearing by over greasing.
4. The PTO shaft also has 4 grease zerks that can be
lightly greased every 50 hours of use.
5. Remove the discharge screen (all models) daily to
avoid material buildup under normal mounting sur-
faces. Clean away material and reinstall screen.
