Complete Guide to Excavator Filter Maintenance: Extend Lifespan and Reduce Malfunctions

1. Routine Maintenance: Inspect, clean, or replace the air filter; clean the internal cooling system; inspect and tighten the track shoe bolts; inspect and adjust track tension; inspect the excavator's intake air heater; replace the bucket teeth; adjust the excavator's bucket clearance; check the windshield washer fluid level; inspect and adjust the excavator's air conditioning; clean the cab floor; replace the breaker filter (optional).

2. Replace the fuel filter and auxiliary fuel filter after 250 hours of operation; check the excavator engine valve clearance.

3. When cleaning the internal cooling system, wait until the engine has fully cooled down before slowly loosening the radiator cap to release the pressure inside the radiator before draining the water; do not perform cleaning while the engine is running, as the high-speed rotating fan can cause danger; when cleaning or changing the coolant, the machine should be parked on level ground; replace the coolant and corrosion inhibitor according to the schedule.
