Maintenance

Figure 14

1. Oil dipstick

2. Drain cock

4.Reinstall all drain plugs and hoses and tighten drain cock.

5.Fill radiator with a 50/50 mix of water and Dex-Cool© coolant as specified in the Check Engine Coolant Level Section, allowing some room (approximately 1/2 inch (12.7 mm)) for expansion. Add 50/50 coolant mix to overflow bottle on the left side of the engine as required to bring the level up to the indicator line on the bottle.

WARNING

Engine compartment contains open belt drives, fans, and other rotating components that can cause injury. Fingers, hands, loose clothing, or jewelry can get caught by the rotating fan and drive shaft.

•Do Not operate machine without the covers in place.

•Keep fingers, hands, and clothing clear of rotating components.

•Shut off engine, wait for moving parts to stop, engage parking brake and remove key, before performing maintenance.

6.With the cap off the radiator, tilt hood closed and put the seat down. Start the engine as stated in the Operating Instructions Section. Return the seat up and hood forward to the open position.

7.Operate engine until the engine thermostat opens and coolant is circulating through the radiator core. As air is purged from the engine block and the coolant level drops, add additional coolant to the radiator.

8.When the radiator is completely full and no additional coolant can be added, continue running and install the radiator cap. Make sure that the cap is completely seated by pressing down firmly while turning until the cap stops. Once the cap is installed, the engine may be stopped.
