1. ELECTRICAL SYSTEM FAILURE
Problems such as blown fuses, faulty wiring, or battery failures can result in power outages, affecting vital equipment like refrigerators, cooking appliances, and POS systems. Regularly inspect and maintain your electrical system.
2. ENGINE TROUBLES
Issues like overheating, ignition failures, or fuel system malfunctions can bring your business to a halt. Follow a strict maintenance schedule, including regular oil changes, tune-ups, and inspections, to keep your engine running smoothly.
3. REFRIGERATION SYSTEM BREAKDOWN
A malfunctioning refrigeration system can lead to food spoilage and jeopardize food safety. Leaky seals, compressor failures, or thermostat malfunctions are common culprits. Regularly clean and inspect your refrigeration system and ensure proper ventilation.
4. PLUMBING FAILURES
Leaky pipes, clogged drains, or malfunctioning water pumps can disrupt your food preparation and cleaning processes. Regularly check for leaks, clear clogs, and maintain proper water pressure.
5. GENERATOR PROBLEMS
Common generator issues include starter failures, fuel supply problems, or generator overload. Perform regular maintenance, clean or replace air filters, and ensure proper fuel levels to prevent generator-related disruptions.
6. EXHAUST SYSTEM BLOCKAGES
Accumulated grease, debris, or blockages can lead to poor ventilation, increased heat, and potential fire hazards. Clean and inspect your exhaust system regularly to ensure proper airflow and minimize fire risks.
7. TRANSMISSION ISSUES
Symptoms like grinding gears, slipping transmission, or difficulty shifting can indicate potential transmission problems. Schedule regular maintenance and promptly address any transmission issues to prevent costly repairs and downtime.
8. BRAKE SYSTEM FAILURES
Brake pad wear, fluid leaks, or faulty brake lines can compromise your ability to stop efficiently. Regularly inspect and maintain your brake system, including brake pads, rotors, and fluid levels, to ensure optimal performance.
9. COOLING SYSTEM MALFUNCTIONS
Monitor coolant levels, check for leaks, and ensure proper radiator functioning to prevent costly engine repairs.
10. TIRE PROBLEMS
Balding tires, uneven wear, or tire blowouts can be dangerous and disruptive. Regularly inspect and maintain your tires, including proper inflation, rotation, and replacement when necessary.
