New Machine Maintenance
Also referred to as "break-in maintenance," this is required for new trenchers or those recently repaired. During the break-in process, observe the operation of all components closely, check and adjust as needed, and promptly address any issues. After the break-in, conduct a full maintenance session as per the user manual.
Daily Maintenance
To keep the trencher in optimal condition, conduct basic maintenance before and after each operation. This includes cleaning, inspecting, lubricating, adjusting, replacing parts, and tightening components.
Scheduled Maintenance
After 200–500 hours of cumulative operation, perform a comprehensive maintenance check. This involves cleaning, inspecting, lubricating, adjusting, replacing worn parts, and repairing damages. Any significantly worn parts should be repaired or replaced before reassembly.
Storage Maintenance
Known as "seasonal maintenance," this is crucial for machines that remain idle for extended periods after a season’s work. Poor storage practices can lead to part deformation, corrosion, aging, or loss, which might shorten the machine’s life or render it unusable. Follow the user manual's storage guidelines carefully.
Specialized Maintenance
This is necessary after incidents such as overturning, submersion, or collisions. Perform targeted repairs to restore the machine's functionality.

Break-In Period
Operate the trencher at moderate speeds and avoid overloading during the first 60 hours.
Engine Maintenance
Adhere to the engine’s user manual, especially regarding lubricant specifications.
Filter Maintenance
Regularly clean or replace the air, fuel, and oil filters as specified in the manual.
Lubrication and Oil Changes
After the first 15–20 hours of operation, replace the oil in the engine and transmission. Subsequently, replace the oil every 50 hours. Ensure the engine is warm during oil changes for thorough draining.
Proper Gear Operation
Always engage the clutch fully before shifting gears. Incomplete engagement can damage the machine.
Blade Safety
Avoid operating the trencher on concrete or rocky surfaces to prevent blade damage. Stop operation and inspect the machine if you hear abnormal sounds from the engine or transmission.
Reversing Precautions
Avoid using reverse gear if the machine is less than 1 meter (3 feet) from a slope.
Oil Replacement During Use
Replace oil in a warmed engine after operating for approximately 5 acres. Clean the air filter every 3–5 days and inspect components such as fuel injectors and piston rings after every 10–15 acres.
Post-Season Cleaning
Remove soil, grass, and oil residues from the trencher after seasonal work. Tighten all bolts and cover the machine to prevent rust from exposure to rain or sunlight.
