4.7 Hillside Operation

WARNING

DO NOT operate on steep slopes.To check a slope, attempt to back up it (with the cutter deck down). If the machine can back up the slope without the wheels slipping, reduce speed and use extreme caution. Under no circumstances should the machine be operated on slopes greater than 15 degrees. ALWAYS FOLLOW OSHA APPROVED OPERATION.

1.This mower has been designed for good traction and stability under normal mowing conditions. However, caution must be used when traveling on slopes, especially when the grass is wet. Wet grass reduces traction and steering control. The Roll-Over Protection System is standard equipment for this machine. See Section 2.5, page 6 of this manual for further details.

2.To prevent tipping or loss of control, do not start or stop suddenly, avoid unnecessary turns and travel at reduced speed. If tires loose traction, disengage blades and proceed slowly off the slope.

3.Avoid sudden starts when mowing uphill. Sudden starts may cause the machine to tip backwards.

4.Loss of traction may occur when traveling down hill. Weight transfers to the front of the machine and may cause the drive wheels to slip causing loss of braking or steering.

5.Keep tires properly inflated.

4.8 Parking The Mower

1.Park the machine on a flat, level surface only. Do not park the machine on an incline.

2.Place the steering control levers in the neutral position.

3.Disengage the cutter blades.

4.Slow the engine to idle speed.

5.Engage the parking brake.

6.Turn the ignition key to the OFF position and remove the key.

4.9 After Operation

1.Wash the entire mower after each use. Do not use high pressure spray or direct the spray onto electrical components.

- IMPORTANT -

Do not wash a hot or running engine. Cold water will damage the engine. Use compressed air to clean the engine if it is hot.

2.Keep the entire mower clean to inhibit serious heat damage to the engine or hydraulic oil circuit.

3.Check the drive belts for proper alignment and any signs of wear. Correct and adjust if necessary.

Danger

To avoid injury from burns, allow the mower to cool before removing the fuel tank cap and refueling.

4.After the mower has cooled down, fill the fuel tank with fresh, clean fuel at the end of every day of operation. See Engine Owner's Manual for proper octane requirements.

5.Check the tire pressure. Adjust pressure if necessary.

4.10 Removing Clogged Material

Danger

ROTATING BLADES

NEVER PUTYOUR HANDS INTOTHE DISCHARGE CHUTE FOR ANY REASON!

Shut off the engine and remove the key and only then use a stick or similar object to remove material if clogging has occurred.

1.If the discharge chute becomes clogged, shut off the engine and remove the ignition key. Using a stick or similar item, dislodge the clogged material. Then resume normal mowing.
