position.
3. Push the control lever forward, and

5. Retract and expand the track width
repeatedly for a few times by moving the
control lever, so that the grease is spread
adequately.
6. Switch the track width change / dozer
select lever to the “Dozer” position.

carefully by moving the dozer blade and
the boom.
