Proper maintenance ensures long-term reliability and peak performance of your welding-generator:

Engine Oil: Check before each use; replace every 50 hrs (or monthly). Ensure proper oil level to lubricate and cool internal components.
Fuel & Air Filters: Inspect and clean air filters every 100 hrs; replace fuel filters and service diesel fuel system every 200 hrs to prevent blockages and maintain smooth operation.
Cooling System: Clean radiator fins regularly and check coolant level if equipped—water-cooled units need periodic flushing and inspection.
Electrical & Safety Systems: Test overload protectors, low-oil shutdown, and circuit breakers periodically; inspect welding cables, output terminals, and grounding components.
General Inspection: Check for fuel leaks, damaged hoses, loose fittings, debris build-up, or exhaust issues before every operation.
Battery & Starter: Inspect battery voltage and charging system every 6 months; clean terminals and replace if necessary.
