system, it is necessary to open both these valves to drain the radiator completely.
When refilling the system, it is important that all trapped air be purged. The following procedure will help to insure this:
1.Make sure the engine is level. Fill the overflow reservoir up to the MAX mark with coolant mixture.
2.Slowly fill the radiator to the bottom of the filler neck with coolant mixture.
3.With radiator cap off, start the engine and let it warm up
4.Reinstall the radiator cap and run the engine a short time with the system sealed while watching the temperature gauge. If the temperature gauge goes past 230 degrees and does not drop back to approximately 190 degrees, indicating the thermostat has opened, allow the engine to cool down, check for leaks and repeat the procedure.
This is a sealed system. If it becomes necessary to add coolant mixture at a later date, check for leaks and if the overflow reservoir has not been drained completely, add coolant mixture to the reservoir only. This will help prevent air pockets in the radiator top tank and lessen the chance of introducing contaminates to the system.
Checking the Parking Brake
Visually check that no damage is found on the lever, links, or switch belonging to the parking brake. Perform a test drive and check that there is a braking effect.
To adjust the parking brake:
1.Set brake lever (D) fully forward against stop.
NOTE: Brake cross shaft MUST be properly lubricated and both cross shaft and over- center assemblies (F) MUST rotate freely.
2.Loosen jam nut (A) at rear of clevis (B) and remove clevis pin (C) both sides of mower.
