lift control manifold.
3. Disconnect the wire harness electrical connector from the solenoid valve
coil that you replace. Note the orientation of the electrical connector on the
coil for assembly purposes.
4. Remove the nut from the hydraulic valve.
5. Slide the solenoid coil from the valve.
6. Clean any corrosion or dirt from the valve.
1. Slide the coil assembly onto the hydraulic valve. Position the coil so that
the connector is properly orientated.
2. Install the nut onto the valve and torque the nut to 6.7 N∙m (60 in-lb).
Note: Do not overtighten the nut.
3. Connect the platform wire harness connector to the solenoid coil.
4. Lower and secure the seat if the deck control manifold was accessed. Install

5. To prevent the battery from freezing during storage, ensure that you charge it
fully; refer to Servicing the Battery (page
1. The battery-electrolyte level must be properly maintained. The top of the
battery must be kept clean. If the machine is stored in a location where the
temperatures are extremely high, the battery will discharge more rapidly than
if the machine is stored in a location where the temperatures are cool.
