3. Safety Information

Always observe the following safety precautions when handling hydraulic oil:

• Read the Machine Manual: Refer to your specific Scag machine's operator's manual for detailed hydraulic system specifications, capacities, and safety procedures.
• Personal Protective Equipment: Wear appropriate personal protective equipment (PPE), including gloves and eye protection, to prevent skin and eye contact.
• Ventilation: Use in a well-ventilated area to avoid inhaling oil mists or fumes.
• Flammability: Keep away from open flames, sparks, and other ignition sources. Hydraulic oil is combustible.
• Skin Contact: In case of skin contact, wash thoroughly with soap and water. Prolonged or repeated skin contact may cause irritation.
• Eye Contact: In case of eye contact, flush immediately with plenty of water for at least 15 minutes and seek medical attention.
• Ingestion: Do not ingest. If swallowed, do not induce vomiting. Seek immediate medical attention.
• High Pressure: Be aware that hydraulic systems operate under high pressure. Leaks can inject oil into the skin, which is a serious medical emergency. Seek immediate medical attention if this occurs.

4. Setup

Before adding or changing hydraulic oil, ensure the machine is prepared correctly:

1. Park on Level Surface: Position the Scag machine on a firm, level surface.
2. Engage Parking Brake: Ensure the parking brake is engaged to prevent accidental movement.
3. Turn Off Engine: Turn off the engine and remove the ignition key. Allow the machine to cool down if it has been recently operated.
4. Locate Hydraulic System: Identify the hydraulic oil reservoir and fill/drain points as specified in your machine's operator's manual.
5. Clean Area: Clean the area around the fill and drain points to prevent contaminants from entering the hydraulic system.
6. Gather Tools: Have appropriate tools ready, such as wrenches, a drain pan, and a funnel.

5. Operating (Adding/Changing Hydraulic Oil)

Follow these general steps for adding or changing hydraulic oil. Always consult your specific Scag machine's operator's manual for exact procedures and capacities.

5.1. Checking Oil Level

1. Ensure the machine is cool and on a level surface.
2. Locate the hydraulic oil reservoir and dipstick or sight glass.
3. Check the oil level according to the machine's manual (e.g., dipstick fully inserted or resting on top, or sight glass indication).
4. If the level is low, proceed to add oil.

5.2. Adding Oil

1. Remove the fill cap from the hydraulic oil reservoir.
2. Using a clean funnel, slowly add SCAG Genuine OEM 20W-50 Hydro System Hydraulic Oil until the level reaches the recommended mark on the dipstick or sight glass. Do not overfill.
3. Replace the fill cap securely.
4. Start the engine and operate the hydraulic functions briefly to circulate the oil.
5. Turn off the engine, allow it to cool, and recheck the oil level. Add more if necessary.

5.3. Changing Oil

1. Warm up the hydraulic system by operating the machine for a short period (e.g., 5-10 minutes) to allow the oil to flow more easily.
2. Turn off the engine and allow it to cool slightly.
3. Place a suitable drain pan beneath the hydraulic oil drain plug.
4. Remove the drain plug and allow all the old oil to drain completely.
5. Replace the drain plug and tighten it to the torque specified in your machine's manual.
6. Remove the fill cap and, using a clean funnel, fill the reservoir with SCAG Genuine OEM 20W-50 Hydro System Hydraulic Oil to the recommended level.
7. Replace the fill cap securely.
8. Start the engine and operate the hydraulic functions through their full range of motion several times to purge air from the system.
9. Turn off the engine, allow it to cool, and recheck the oil level. Add more if necessary.

6. Maintenance

Regular maintenance of your hydraulic system is crucial for longevity and performance:

• Follow Service Intervals: Adhere strictly to the hydraulic oil change intervals recommended in your Scag machine's operator's manual.
• Inspect for Leaks: Periodically inspect all hydraulic hoses, fittings, and components for signs of leaks. Address any leaks promptly.
• Filter Replacement: Change hydraulic filters at the recommended intervals. Dirty filters can restrict oil flow and damage components.
• Keep System Clean: Ensure the hydraulic system and surrounding areas are kept clean to prevent contamination.
• Use Genuine Parts: Always use genuine Scag hydraulic oil and filters to ensure compatibility and optimal performance.

7. Troubleshooting

If you experience issues with your hydraulic system, consider the following common troubleshooting steps:

• Low Hydraulic Power: Check the hydraulic oil level. A low level can cause reduced power. Also, inspect for leaks and ensure the hydraulic filter is not clogged.
• Unusual Noises (Whining/Grinding): This can indicate low oil level, air in the system, or a clogged filter. Check the oil level and bleed the system if necessary (refer to machine manual).
• Overheating Hydraulic System: Ensure the oil level is correct. Overheating can be caused by low oil, a clogged cooler, or internal component issues.
• Oil Contamination: If the oil appears milky, dark, or contains particles, it may be contaminated. This requires an oil and filter change and inspection of the system for the source of contamination.
• Sudden Loss of Function: Check for severe leaks, a completely clogged filter, or a major component failure.

For persistent or complex issues, consult your Scag machine's operator's manual or contact an authorized Scag service technician.

8. Storage and Disposal

• Storage: Store SCAG Genuine OEM 20W-50 Hydro System Hydraulic Oil in its original container, tightly sealed, in a cool, dry place away from direct sunlight and extreme temperatures. Keep out of reach of children and pets.
• Disposal: Dispose of used hydraulic oil and empty containers responsibly and in accordance with all local, state, and federal regulations. Do not pour used oil down drains or onto the ground. Many automotive service centers and recycling facilities accept used oil.
