Safety Operation Instructions
To ensure safe operation and extend the service life of the
equipment, please follow the safety instructions below.
Qualified Operators
Only trained personnel should operate the machine. Operators must
carefully read and understand the instruction manual before use.
Never Service While Running
Do not adjust, clean, lubricate, or repair the machine while it is
operating. Always switch off the power supply and wait until all
moving parts have completely stopped before performing any
maintenance.
