name or number of permanent marks. 2) need to be manually opened the selector valve, open revolving arm while
pull pressure arm
5. Maintenance instructions:
appearance inspection should be monthly, no collision deformation and mechanical damage, surface rust,
derrick and pressure arm flexible rotation without binding may continue to use.
