Wujexuhe Auto Oiler Assembly Pump for Echo CS-550P CS-600P CS-590 CS-620P CS-620PW – Replaces C022000050-053

Efficient lubrication on demand

The Wujexuhe Auto Oiler Assembly Pump is a purpose-built replacement part designed for Echo chainsaws. When the saw is in use, this module automatically delivers lubricant to the guide bar and chain, helping to maintain a steady oil film where it matters most. The result is a smoother cutting experience, with fewer interruptions for manual lubrication and a more consistent overall performance.

Why this replacement matters

Crafted from a high-quality metal alloy, the pump emphasizes wear resistance and durability. Its robust build is designed to withstand the vibrations of a running saw, offering a longer service life and reducing the frequency of replacements. While individual results vary, users appreciate the potential for more stable lubrication during demanding sessions, which can help manage heat and friction in real-world use.

How it works in practice

As the saw runs, the pump draws lubricant from the reservoir and delivers it along the bar and chain, creating a protective film that supports smoother cuts. The metal body helps resist wear and maintains performance even under vibration and load.

Installation and care tips

• Power off the saw and disconnect any power source before installation.
• Verify model compatibility and part numbers before purchasing or installing.
• Follow your Echo saw’s manual for installation steps and torque specifications.
