Lubrication of tools:
In order to ensure the normal use of tools, please pay attention to the replacement and addition of lubricating oil. If the screw loose
causes oil leakage, please pay attention to timely maintenance. Continuous use of oil leakage will cause tool failure and reduce service
life.
Inspection and maintenance:
When a tool is granted or withdrawn, the storeman must conduct a daily check; before use, users must conduct routine checks.
The daily inspection of tools should include the following items:
1)Whether there are product certification marks and regular inspection of qualified marks.
2)Whether the shell or handle is cracked or broken.
3)Protection of grounding wire (PE)connection is not broken.
4)Whether the power line is intact.
5)Whether the power plug is intact.
6)Make sure the power switch is normal and flexible, whether there are defects or breakages.
