To inspect the safety start interlock system:

1.Park the unit on a flat, level surface.

2.The operator must be on the seat when testing the seat switch.

3.Engage the park brake.

4.Start the engine and allow it to warm up to operating temperature.

5.With the PTO disengaged, slowly raise off of the seat.

The engine should continue to run.

6.Disengage the park brake and with the PTO disengaged, slowly raise off of the seat. The engine should stop.

7.Engage the park brake and the PTO, slowly raise off of the seat. The engine should stop.

8.If the engine fails to stop and the operator is off the seat, check the function of the seat switch. If the seat switch is not operating properly (is not opening or closing) and if the cause can not be determined, replace the seat switch.

If the problem can not be located, contact your Hustler Dealer.

WARNING: The safety interlock system should always function per steps 2 thru 6. If it does not function properly, it should be corrected immedi- ately. Do not operate machine without properly functioning seat safety switch.

PTO stop system:

While operating PTO driven equipment, the PTO will disengage automatically when the equipment is raised by the lift control lever to the maximum lift height.

NOTE: The PTO control lever remains in the engaged position after activating the PTO stop device (the PTO shaft will no longer rotate). To re-engage the PTO, the PTO control lever must be moved to the “OFF” position, then pushed for- ward again.

To inspect the PTO stop system:

1.The operator must be on the seat when testing the PTO switch.

WARNING: Perform this test in an area free of any bystanders.

2.Set the park brake.

3.Start the engine and allow it to warm up to operating temperature.
