WARNING
Do not attempt any servicing or adjustments with the engine running.
Use extreme caution while inspecting the drive belt assembly, and all vehicle linkage!
Follow all safety procedures outlined in the vehicle owner’s manual!
In many cases problems with the 310-2400 IZT are not related to a defective transaxle, but are caused by slipping drive belts, partially engaged bypass valves, and loose or damaged control linkages. Be sure to perform all operational checks and adjustments outlined in Section 4, Service and Maintenance before assuming the unit is malfunctioning. Table 2 below provides a troubleshooting check list to help determine the cause of operational problems.
