Hydraulic System
Change the Oil
 |
Hot oil cause burns. At operating temperature, the hydraulic tank is hot and under pressure. Remove the fill cap only when the engine is stopped, and the cap is cool enough to touch with your bare hand. Remove the fill cap slowly to relieve pressure. |

Cooling System - Perkins Engine
Change the Coolant
|
At operating temperature, the engine coolant is hot and under pressure. Steam can cause personal injury. Check the coolant level only after the engine has been stopped and the fill cap is cool enough to touch with your bare hand. Remove the fill cap slowly to relieve pressure. Cooling system conditioner contains alkali. Avoid contact with the skin and eyes to prevent personal injury. |

| NOTICE |
|---|
Never add coolant to an overheated engine; allow the engine to cool first. Check the specific gravity of the antifreeze coolant solution frequently in cold weather to ensure adequate protection. If the machine is to be shipped to, or stored in, an area with temperatures below 0°C (32°F), the cooling system must be protected to the lowest expected outside temperature. All water is corrosive at engine operating temperatures. The cooling system should be protected with a 3% to 6% concentration of cooling system conditioner at all times regardless of the concentration of antifreeze. Do not use AVSpare cooling system conditioner with Dowtherm 209 Full-Fill coolant. Follow the instructions provided with Dowtherm 209 Full-Fill coolant. |
Coolant should be drained and replaced every 2000 service hours or 1 year. However, when liquid cooling system conditioner is added every 250 service hours as recommended, the drain period can be extended to 4000 service hours or 2 years.
A 3% to 6% concentration of AVSpare cooling system conditioner can be maintained by adding conditioner as specified.
Premix antifreeze coolant solution to provide protection to the lowest expected outside temperature. Pure undiluted antifreeze will freeze at -23°C (-10°F).
Use clean water that is low in scale forming minerals. Do not use softened water.
Filling at over 20 liters (5 U.S. gallons) per minute can cause air pockets in the cooling system.
When the engine is shipped from the factory, its cooling system is protected to -28°C (-20°F), with permanent-type antifreeze.
Operate with a thermostat in the cooling system year-round. Overheating will occur without a thermostat.
NOTE: Radiator cap location could be on top, depending on which engine you have.
- 1. Remove the radiator cap access cover.
- 2. Loosen the radiator coolant cap slowly to relieve pressure, and remove the cap.
- 3. Open the drain valve under the radiator and allow coolant to drain into a container.
- 4. Close the valve.
- 5. Remove the drain plug on the engine block and allow coolant to drain. Install the plug.
- 6. Fill the cooling system with a cleaning solution. Use a commercially available cleaner or 1 kg (2 lbs) sodium bisulfate per 38 liters (10 gal) water as a cleaner.
- 7. Start and operate the engine for 1/2hour.
- 8. Stop the engine and drain the cleaning solution.
- 9. Flush the system with water with the engine stopped, until draining water is clear.
- 10. Close the drain valve. Fill the system with a neutralizer. Use a commercially available neutralizer.
- 11. Operate the engine for ten minutes.
- 12. Stop the engine and drain the neutralizer.
- 13. Flush the system with water with the engine stopped, until the draining water is clear.
- 14. Close the drain valve.
- 15. Fill the system with clean water and operate the engine for five minutes.
- 16. Drain the cooling system and close the drain valve.
- 17. Repeat the flushing procedure until the draining water is clear.
- 18. Add the coolant solution. See "Refill Capacities."
Also add .95 liters (1 quart) of coolant system conditioner.
- 19. Start the engine and operate it with the radiator cap off, until the thermostat opens and the level stabilizes.
- 20. Maintain the coolant level about 15 mm (.62 inch) below the top of the fill tube.
- 21. Install the radiator cap.
- 22. Stop the engine.
