Allow fresh outside air into the work area to clear the exhaust fumes out.Engine Oil (Gas)Use oil viscosity based on the expected air temperature range during the period between oil changes.The following John Deere oils are preferred. IMPORTANT: Avoid damage!
Failure to check the oil level regularly could lead to serious engine problems if oil level is low: Check oil level before operating. Check oil level when the engine is cold and not running. Keep level between the FULL and the ADD marks. Shut off engine before adding oil.NOTE: Check oil twice a day if you run engine over 4 hours in a day.Make sure engine is cold when checking engine oil level.1. Park machine safely.
(See Parking Safely in the Safety Section.)2. Clean area around dipstick to prevent debris from falling into crankcase. Open drain valve (A) and drain oil into oil drain pan. Allow oil to drain completely.6.

Tighten filter an additional one-half turn.12. Close drain valve.13. Install and tighten dipstick.15. Start and run engine at idle to check for leaks.
Fix any leaks before operating.16. Check oil level, add oil if necessary.Cleaning Air Intake Screen. IMPORTANT: Avoid damage! Dirt and debris can enter the engine through a damaged filter element: Do not wash paper element. Do not attempt to clean paper element by tapping against another object.
Do not use pressurized air to clean element. Replace element only if it is very dirty, damaged or the seal is cracked.8. If precleaner is dirty, clean it as follows: Wash it in a solution of warm water and liquid detergent.
DO NOT wash paper element. Rinse precleaner. Squeeze excess water from precleaner.

Install hood.Recommended Engine CoolantThe following John Deere coolant is preferred: COOL-GARD PRE-DILUTED SUMMER COOLANT (TY16036). COOL-GARD CONCENTRATED SUMMER COOLANT (TY16034)If neither of the above coolants is available, use an ethylene glycol base coolant that meets the following specification: ASTM D4985 (JDM H24A2)Check container label before using to be sure it has the appropriate specifications for your machine. Use coolant with conditioner or add conditioner to coolant before using.If using concentrate, mix approximately 50 percent antifreeze with 50 percent distilled or deionized water before adding to cooling system. This mixture will provide freeze protection to -37 degrees C (-34 degrees F).Certain geographical areas may require lower temperature protection. Observe coolant in recovery tank (A). Coolant level should be up to H mark (B) on recovery tank when engine is hot or to L mark (C) when engine is cold.3. Remove cap (D) to add coolant.4.
If coolant is low, add ethylene glycol (without stop-leak additive) antifreeze and water in the ratio specified on the antifreeze container.5. Install and tighten recovery tank cap.6. Clean debris from air intake screens and radiator.7. Check condition of hoses. Check for leaks or loose connections.Draining Cooling Systemc CAUTION: Avoid injury! The radiator will be hot and can burn skin.
Built-up pressure may cause explosive release of coolant when the radiator cap is removed: Shut off the engine and allow to cool. DO NOT remove the cap unless the radiator and the engine are cool enough to touch with bare hands. Slowly loosen the cap to the first stop to release all pressure. Then remove the cap.1. Stop the engine and let cool.2. M56254Picture Note: Hose is located on the left side of the engine.4.
Remove top hose clamp (B). This is the small hose that runs from the water pump to the cylinder head.5. Hold a bucket below the hose. Pull hose off of fitting and drain coolant into bucket.NOTE: There should be very little coolant escape from the cylinder head fitting if the pressure has been released from the radiator and the cap installed tightly.6. After coolant has drained, install hose and clamp to cylinder head fitting.7. Flush cooling system. (See Flushing Cooling System in this section.)Flushing Cooling Systemc CAUTION: Avoid injury!
The radiator will be hot and can burn skin. Built-up pressure may cause explosive release of coolant when the radiator cap is removed: Shut off the engine and allow to cool. DO NOT remove the cap unless the radiator and the engine are cool enough to touch with bare hands.
