Maintenance and Care Recommendations

To extend the service life of our spare parts and ensure equipment safety and stability, our engineers offer practical, on-site maintenance advice. For the 2.41.011 Air filter, clean the filter media every 150 working hours and replace it every 750 working hours—this avoids clogging, a step many teams skip until engine overheating occurs. A key engineer tip: never reuse 2.4.51.418 O-seals or 2.4.99.1005 sealing rings, as even minor damage can cause leaks that lead to hydraulic system failure, and always verify seal compatibility with your equipment’s as-built documentation. For the 2.4.35.003 Parker hinged head TPEC top drive, inspect the locking mechanism every 200 working hours and tighten to the recommended torque of 90 N·m. The 2.4.03.002 filter element should be replaced every 450 working hours, and the 2.2.08.010 Cartridge valve should be inspected every 300 working hours for leakage. Never mix different types of bolts (like 4.10.01.068 Hexagon bolt and 4.10.01.030 Hexagon socket head cap screws), as this can lead to uneven load distribution and component failure. Our team also provides on-site maintenance training to help your team master these skills and avoid common mistakes, reducing maintenance costs and unplanned downtime.
