Troubleshooting, Adjustments, & Service

HYDRAULIC PUMP DRIVE BELT REPLACEMENT

1.Park the rider on a smooth, level surface such as a concrete floor. Disengage the PTO, engage the parking brake, turn off the engine, and remove the ignition key.

2.Remove the PTO drive belt (see MOWER BELT REPLACEMENT for removal instructions).

3.Loosen the nut towards the front of the machine on the spring anchor hook (H, Figure 38) to release the majority of the belt tension. Use caution and remove the nut to completely release the tension.

4.Remove the old belt and replace it with the new one. Make sure the V-side of the belt runs in the grooves of the crankshaft pulley and pump pulleys (B & C).

5.Reinstall the anchor hook (H) into the anchor tab and loosely fasten the nut. Adjust the spring until a measurement of 7-3/4” (19,7cm) is achieved from the outside of the spring hooks. Tighten nut.

6.Reinstall the PTO drive belt.

Troubleshooting

BATTERY CHARGING

A dead battery or one too weak to start the engine may be the result of a defect in the charging system or other electrical component. If there is any doubt about the cause of the problem, see your dealer. If you need to replace the battery, follow the steps under Cleaning the Battery & Cables in the Regular Maintenance Section.

To charge the battery, follow the instructions provided by the battery charger manufacturer as well as all warnings included in the safety rules sections of this book. Charge the battery until fully charged. Do not charge at a rate higher than 10 amps.

BATTERY CHARGINGWARNING

Keep open flames and sparks away from the battery; the gasses coming from it are highly explosive. Ventilate the battery well during charging.
