Why is it important to replace the oil seal and piston?
Replacing the oil seal and piston on your CH-70 punching machine is essential to maintain its performance and prevent further damage. A worn-out oil seal can lead to oil leaks, while a damaged piston can affect the machine's punching power. By replacing these components in a timely manner, you can prolong the lifespan of your machine and ensure consistent results.
Follow these steps to replace the oil seal and piston on your CH-70 punching machine, and keep it running smoothly for years to come.
After a period of use, the oil seal in the piston of the CH-70 punching machine needs to be replaced regularly. Because impurities may enter the hydraulic oil during use, causing wear of the piston and oil seal, try to keep the working environment clean during use, so as to extend the service life of the oil seal and piston.
