SECTION 3. TROUBLESHOOTING
In many cases, problems with the EZT
®
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 pump
is malfunctioning. Table 3 below provides a
troubleshooting checklist to help determine the
