d.After cleaning, apply a coating of clear battery post protectant to terminals and cable connections.

3.Check for loose or worn cables. Replace if worn.

DRIVE CHAIN MAINTENANCE

Inspect drive chain periodically for proper tension. Chain should flex between 6.35mm (0.25 in ) and 12.7mm (0.50 in) from center. If chain flexes more than 12.7mm (0.50 in), chain should be tightened.

FOR SAFETY: Before leaving or servicing machine, stop on level surface, turn off machine and pull out main circuit breaker button.
