Asphalt heaters provide an efficient, user-friendly solution for repairing road damage such as potholes, cracks, and uneven surfaces, ensuring reliable performance in road maintenance projects.Proper maintenance is also crucial.
1. Regular Cleaning
Exterior & Heating Surface: Remove asphalt residue, dust, and debris after each use to prevent clogging and overheating.
Burner & Ignition System: Clean propane nozzles and ignition components to ensure smooth operation.
2. Propane System Inspection
Check for Leaks: Use a soapy water solution on gas connections; bubbles indicate leaks (tighten or replace faulty parts).
Fuel Lines & Regulator: Inspect for cracks or wear; replace if damaged.
Tank Safety: Ensure the propane tank is securely mounted and free from rust/dents.
3. Heating Element & Temperature Control
Thermal Sensors: Verify accuracy using an external thermometer; recalibrate if readings deviate.
Digital Timer & Controls: Test functionality and replace batteries if needed.
Burner Maintenance: Clean the burner nozzles monthly to sustain high heat output and prevent uneven heating.
4. Mobility & Structure
Self-Propelling System: Lubricate wheel bearings and check tire pressure regularly for smooth mobility.
Frame Integrity: Inspect welds and heat-resistant materials for cracks caused by thermal stress.
5. Mechanical Components
Wheels & Axles: Lubricate bearings and check tire pressure monthly.
Sprayer System (if equipped): Flush with solvent after use to prevent emulsion buildup.
6. Safety Checks
Fire Extinguisher: Keep a Class B extinguisher nearby for propane-related fires.
Ventilation: Ensure proper airflow during operation to avoid gas accumulation.
Emergency Shutoff: Test the shutoff valve regularly.
7. Professional Servicing
Annual Tune-Up: Have a technician inspect the ignition system, heating elements, and structural integrity to ensure rapid, cost-efficient repairs.
8. Seasonal Storage
Drain Fuel: If unused for extended periods, empty the propane tank or store it separately.
Cover Unit: Protect from weather using a waterproof tarp.Protect from moisture and UV exposure during long-term storage.
Indoor Storage: Preferred to prevent rust and rodent damage.
Winterizing: Drain all fuel lines and the sprayer system to prevent freezing damage.
Proper maintenance ensures efficient heating, safety, and longevity of your trailer asphalt heater.
