V. Installation and Maintenance

(I) Installation Specifications

Check the piston and supporting parts for defects before installation; clean the cylinder liner and check its wear.
Use special tools for installation; apply appropriate engine oil to the piston skirt, pin hole and piston ring.
Install piston rings in correct order, stagger their openings, and ensure retaining rings are firmly embedded.
Check the fit clearance after installation; rotate the crankshaft to ensure smooth operation.

(II) Daily Maintenance

Regularly check oil level and quality; replace oil and filter every 2000 hours, check every 500 hours.
Clean carbon deposits every 3000 hours with special cleaning agent.
Avoid long-term high-load operation; idle for 3-5 minutes before starting work.
Check piston status every 1000 hours; shut down and maintain in case of abnormal conditions.
Fully maintain the engine before long-term shutdown to prevent rust and corrosion.

(III) Common Fault Handling

Slightly scratched pistons can be repaired by special grinding tools; replace pistons if there are cracks, ablation or severe wear (wear over 0.15mm or cylindricity error over 0.05mm); repair or replace if the fit clearance between piston pin and hole is too large (over 0.015mm).
