The foot brake is connected with a micro switch. It should
have 0 to 1mm end play between the brake arm and the
switch’s roller head. The correct brake action should cut off
the electricity first, and then brake to avoid the brake belt
being worn out. After stepping on the foot brake, user needs
to reset and re-engage the spindle operation control lever to
make the spindle rotate again. Fig. 6-6

If there is no coolant coming out after the pump switch is turned on, please check the
pump motor is turning or not. If yes, please check to see if the coolant in the tank is
over the pump or not? If not, please add coolant, and then turn on the switch, if there
is still no coolant coming out, the pump must be blocked. Please remove the pump
and clean up for repair.
