Always use a properly grounded electrical outlet of correct voltage
and current handling capacity.
Always inspect the rubber supports, replace the new one when
required in order to keep the rotor balanced.
The drive motor and linkage assembly do not require lubrication.
Inspect and replace the carbon brushes yearly or according to the
operation frequency or whenever it needs.
Use compressor to clean the dust inside the chamber that is

safety device is working.
A 10A fuse is equipped inside the circuit board to encounter the
