TORO GM 325-D	Mitsubishi K3D Diesel Engine 27

Troubleshooting:

High and Low Idle Checks.

The idle settings are important for the proper operation and long life of the machine.

Affects of incorrect idle speeds:

1.High idle too slow.

∙Low power. (Engine not running at full speed)

∙Slow transport speed. (Hydrostatic transmission input shaft speed too slow)

∙Poor Quality of cut. (Blade RPM and tip speed too slow)

2.High idle too fast.

∙Internal engine damage. (Excessive engine RPM can damage crankshaft and bearings)

∙Hydrostatic transmission damage. (insufficient lubrication for high input shaft speeds)

∙Engine overheating.

3.Low idle too slow.

∙Hydrostatic transmission damage.(lack of lubrication)

Checking Idle Speeds

1.Run the engine until it reaches normal operating temperature.

2.Move the throttle lever to the low idle position.

∙Low idle should be 1500 ± 50.

3.Open the throttle to the high idle position.

∙ High idle should be 3145 - 3200.

Note: if the high and low idle is incorrect, refer to the Operators Manual for the correct adjustment procedures
