How often should the oil in the chain casing be changed?

Changing the oil in the chain casing every 3 months is considered a good practice to ensure optimal performance and extend the life of the equipment. Regular oil changes help maintain proper lubrication, which can reduce friction and wear on the moving parts within the chain casing. Additionally, over time, the oil can become contaminated with dust, debris, and metal particles, which can compromise its effectiveness. By changing the oil every 3 months, operators can help to ensure that the lubrication system remains effective, thereby preventing potential mechanical failures and reducing maintenance costs in the long run. This frequency is a balanced approach that aligns with common maintenance schedules used in wastewater operations.
