Keep parts clean to prevent dust, debris, and oil contamination. Clean the IMPELLER 3X2X13 19204-20-30 monthly to remove dust buildup, which can reduce airflow and increase energy consumption. For hydraulic and pneumatic fittings, clean the thread and sealing surfaces before installation to prevent leaks. Wipe down electrical parts regularly to remove dust, which can cause overheating.
4. Storage
Store unused parts in a dry, clean, and well-ventilated environment, away from direct sunlight and corrosive media. Seals and O-rings (QB7407-2005, YXD120) should be stored in a cool place (temperature ≤25℃) to prevent aging and hardening. Mechanical parts (shafts, brake discs) should be coated with anti-rust oil before storage to prevent corrosion.
5. Replacement Guidelines
Replace parts when they reach their recommended service life: fuel filters (57415610, 1R0755) every 500 operating hours or 6 months (whichever comes first), seals and gaskets every 6-12 months, and hydraulic hoses every 12-18 months. Replace any part that shows signs of excessive wear, damage, or failure to avoid equipment breakdown. Always use genuine parts—generic parts can reduce equipment service life by 50% and increase the risk of unplanned downtime.
