NOTICE

Always inspect primary element before and after cleaning with a light bulb inside the element. Discard if any tears, rips or damage is evident.


5. Install clean element and cover.

6. Reset filter indicator.

If indicator shows RED shortly after installation of a primary element which has been cleaned approximately 6 times, change to another clean element.

NOTE: The primary element should be replaced after being cleaned a maximum of 6 times. Replace the element once a year even though it has not been cleaned 6 times.

If indicator still shows RED shortly after the installation of the clean primary element, change the secondary element.

------WARNING!--------

7. Dry and install precleaner.

8. Uncover air inlet openings and install new secondary element.

9. Install primary element and cover.

10. Reset filter indicator.

Cleaning Air Cleaner Elements

2. Direct water outside along length of pleats. Rinse, air dry thoroughly and check element.

Detergent

1. Wash in warm water and non-sudsing household detergent.
2. Rinse with clean water, 40 PSI max. (3 kg/cm2), see above.
3. Air dry thoroughly and check element.

Checking Element

1. Insert light inside clean and dry element and check. Discard element if tears or rips are found.

2. Wrap and store good elements in a clean dry place.

------ WARNING! ------

When using pressure air, wear safety face shield and protective clothing. Use 30 PSI (2 kg/cm2) maximum pressure air for cleaning purposes.

------WARNING!--------


NOTICE

Do not clean elements by bumping or tapping.

Do not use elements with damaged pleats, gaskets or seals.


NOTE: Have spare elements on hand to use while cleaning used elements.

(34)Cooling System

Whenever draining and refilling the cooling system, always recheck the coolant level when the engine reaches normal operating temperature.

Stop engine. Remove cap slowly to relieve pressure. Maintain coolant level 1/2 inch (1 cm) below the bottom of the fill pipe.

Use clean water that is low in scale forming minerals - not softened water.

Never add coolant to an overheated engine, allow engine to cool first.

Add AVSpare Corrosion Inhibitor or equivalent. Follow recommendations on container.

Check specific gravity of antifreeze solution frequently in cold weather to assure adequate protection.

------ WARNING! ------

Inhibitor contains alkali, avoid contact with skin and eyes.

------WARNING!--------

NOTE: If machine is to be stored in, or shipped to an area with below freezing temperatures, refer to Item 30 on Page 28.

Cleaning the Cooling System

1. Run engine until coolant is at operating temperature. Park machine on level and stop engine.

2. Turn filler cap slowly to relieve pressure, then remove cap.

3. Open radiator drain valve and allow coolant to drain.
4. Close drain valve and fill system with cleaning solution. (1)
5. Start engine and run for 1/2 hour. Stop engine and drain cleaning solution.
6. Flush system with clean water until draining water is clear.
7. Close drain valve and fill system with neutralizing solution. (2)
8. Start and run engine for 10 minutes. Stop engine and open drain valve.
9. Flush system with clean water.
10. Close drain valve and slowly add coolant. See REFILL CAPACITIES.


(1)2 lb. Sodium Bisulphate (NaHSO4) per 10 gal. water (25 grams per liter).


(2)1/2 lb. Sodium Carbonate Crystals (Na2CO3 · 10 H2O) per 10 gal. water (6 grams per liter).

NOTE: Most commercial cooling system cleaners may be used.

------ WARNING! ------

Use all cleaning solutions with care.

------WARNING!--------

(35)Fuel System Fuel Filter

NOTE: Change filter when fuel pressure gauge registers OUT with engine running.

Close supply valve by turning start-run switch to OFF. Turn disconnect switch to OFF.

Primary Fuel Filter (71M1 - 71M2548)
