Maintenance Tips

• Pre-Use Inspection: Check for fuel leaks, loose fittings, and worn components before each operation. Ensure air intakes and exhaust outlets are clear.
• Use Clean, High-Quality Fuel: Always use clean, high-grade diesel fuel. Drain water and contaminants from the fuel tank and filter regularly to prevent clogging.
• Check and Change Engine Oil: Monitor oil levels and change oil at recommended intervals using manufacturer-approved engine oil to maintain peak performance.
• Inspect and Clean Air Filter: Ensure proper airflow by cleaning or replacing air filters as needed. A clogged filter can reduce efficiency and damage engine components.
• Monitor Coolant Levels: Check coolant levels regularly to prevent overheating. Use the recommended coolant mix to maintain proper engine temperature.
• Inspect Exhaust System: Ensure the exhaust system remains free of blockages and leaks. Keep vents and ducting clear for safe heat distribution.
• Test Safety Systems: Verify the function of all safety controls, including flame sensors, emergency shutoff mechanisms, and temperature controls.
• Check Electrical Connections: Inspect and secure all electrical wiring and connections to prevent malfunctions, especially after transport or prolonged use.
• Clean Heater Components: Remove dust, soot, and debris from the heater’s internal components to maintain efficiency and prevent damage.
• Proper Storage: When not in use, store in a dry, well-ventilated area. If storing long-term, drain the fuel and protect key components from moisture and corrosion.
