Package And Service

Track Link Maintenance
Before enabling the track link, first check whether the link assembly is operating normally and whether the tension of the saw chain is normal.
Remember to close the chain brake before starting so as to stop the track link assembly and prevent danger during startup. But loosen the chain brake before work, otherwise the bearing will be damaged.
When the track link assembly rotates, be careful not to rub against the ground or other objects.
The link assembly should be oiled and applied with anti-rust paint in a timely manner. Once the track link assembly is rusted, it should be replaced in time to improve work efficiency.
Check and maintain the link assembly frequently, repair it in time if there is a broken link or disconnection, and find out the cause.
