Brakes are critical to the safe operation of the machine.
Check the function of the brakes frequently. Refer to
Section “Maintenance – Check Brakes”. If adjustment is
required, complete each of the following steps carefully.
Always verify that the brakes function properly after
performing any brake adjustments. Do Not operate the
machine if the brakes are not functioning properly.

functioning properly. Adjust, repair or replace as
necessary. Contact your local authorized dealer for
assistance.
