tinue use and contact service personnel.
Checking the rubber tracks
• If broken steel ropes are noted discontinue use until
damaged components are replaced
• If broken metal cores are noted discontinue use until
damaged components are replaced
• If metal cores are separating discontinue use of the
machine until the damaged components are replaced.

mounting torque.
TRACK NUTS MUST BE INSTALLED AND MAINTAINED AT THE
PROPER TORQUE TO PREVENT LOOSENING OF THE TRACK, BRO-
KEN STUDS, AND POSSIBLE DANGEROUS SEPARATION OF THE
