Maintenance
One,Notice
- Machine should be oiled by the rustproof grease, before using. On
using, reoil machine and assemble it .
- When connecting water pipe and air pipe, blow off dirty to protect
parts.
- Before open machine, should inspect the flexibility and reliability
of all control structure and operation part; oil reservoir be
filled with lubrication, and measure oil quantity well, ensure
machine run regularly.
- When finishing using machine, cut off water supply and let machine
run slowly, then blow off the rest moisture to avoid rusting parts.
- The machine which often use, should pay attention to maintenance.
Examine and repair every week at least, Clean the dirty within the
machine and note to replace and change the damage and invalidation
parts, eliminate the malfunction and hidden trouble.
- If machine should store for a long time, diamantle machine for
clean, oil and seal , then placed a dry place.
Two,Lubrication
Lubrication has great influence in the performance and working
life．Do not operate machine without lubricating oil
