Hey Lee...
I got a machine from ASIA also... My Spindle was not wired correctly...
We have 3phase Y type power.. meaning we have 120/ 208Volts...
The spindle was wired for 380... so during testing, it seemed underpowered and we snapped a 3/8 bit...
It took some time and investigation.. and luckily my HSD was a genuine model (not chinease) and was configurable for 220 or 380..
Some electrical rework.. and we got it cutting SUPER...
