Installation and maintenance tips

To maximize lifespan and performance:

• Match the EK 420 H/Duty Chain with compatible standard 420 sprockets and guides for a secure drive.
• Check tension and alignment before startup to prevent uneven wear and premature elongation.
• Keep chains lubricated with a suitable roller-chain oil or lubricant recommended for heavy-duty chains; avoid harsh solvents that can degrade the coating or metal.
• Periodically inspect for wear, elongation, bent links, or damaged rollers; replace worn chains in sets to prevent mixed wear patterns.
