Section 7

3. Replace the radiator cap. Push down on the cap and

turn clockwise until it stops.

-NOTE-

The cooling system should be flushed and the

coolant replaced every 500 hours of operation

or annually. See your Scag dealer for proper

coolant replacement.

B. Cleaning the Radiator Debris Screen

After each day of operation, remove and clean the

radiator debris screen.

1. Pull the debris screen up to remove.

2. Clean the debris screen with compressed air or a

water hose.

-NOTE-

Check the radiator for excessive debris and

clean with compressed air. Never spray a hot

engine with water, use only compressed air to

remove debris.

3. Re-install the debris screen to the radiator.

C. Checking The Fan Belt Tension

Periodically check the fan belt tension. The belt should

deflect 1/2" with 10 pounds of pressure. See your Scag

dealer if the belt is in need of adjustment or replacement.

To avoid personal injury, always wear safety
glasses when using compressed air.

CAUTION:

Do not wash any portion of the equipment
while it is hot. Do not wash the engine; use
compressed air.

CAUTION:

1. After each use, wash the mower and cutter deck.

Use cold water and automotive cleaners. Do not use

pressure cleaners.

2. Do not spray electrical components.

3. Use a mild soap solution or a vinyl/rubber cleaner to

clean the seat.

4. Repair damaged metal surfaces using Scag touch-up

paint available from your authorized Scag dealer.

Wax the mower for maximum paint protection.
