purged. It is necessary to purge these bearings everyday until clean grease is seen. CAUTION

should be taken not to allow grease to build up inside the belt guards.

• Remove the Poly Chain® belt guard cover and

bottom cover. See the Servicing Belts section to

remove the Poly Chain

® belt and cutter wheel

sprocket.

• Remove the four bolts on the cutter wheel

bearings. The cutter wheel will be free from the

machine at this point. With the Poly Chain

belt removed, you can start the machine and

raise the boom up.
