MAYA Embroidery Machine
Maintenance and solutions
1. Maintaining:
Embroidery machines are a kind of high-speed
running machines, and in most of the factories, they are running 24
hours per day and 7 days per week, in this case, the daily maintenance
to the machines is vital to keep the machines work continuously with
efficiency under its good performance. To be specific, regular cleaning
with soft brush and frequently adding lube (little amount each time)
are necessary. Timely and regular services to the machine are a guaranty
to endure the life of the machine.
2. Checking:
Because the machine works with high speed,
the moving part and relevant screws is possibly becoming loose. Generally,
the sound it produces can be the signal of its status. The following
should be noticed:
A. Tell whether it works well by its noise
B. Check its movements
C. Check its smell
D. Check the power regularly
E. Make sure the panel is clear
F. Make sure the lube is added
