Brake & Micro Switch Adjustment
The foot brake is connected with the
micro switch. There should be 0-1mm
end play between the brake arm and the
head of the micro switch(See Fig. 7-7).
The proper function of the brake is to
first, cut off the power and then engage
the brake belt. After using the brake, it
is necessary to use the control lever to
re-start the lathe.
