EVS Toolroom Lathe w/DRO

  Move the spindle ON/OFF lever down to 

start the spindle rotating counterclockwise 
(down toward the front of the lathe).

— If the spindle rotates in the opposite 

direction (clockwise), the power supply 
phase polarity may be incorrect. Refer to 
Correcting Phase Polarity on Page 92 
to resolve this.

Observe the lathe and listen for any 
abnormal noises or vibration. The lathe 
should run smoothly.

  Push the STOP button. The spindle should 

come to a slow stop.

  Move the spindle ON/OFF lever up to the 

OFF (middle) position, reset the STOP 
button by twisting it clockwise until it pops 
out, then restart spindle rotation by moving 
it down again.

  Press the foot brake. The spindle should 

come to a quick stop.

— If the foot brake has no effect on the 

stopping speed of the spindle, push the 
STOP button and refer to Brake Service 
on Page 82 to adjust the brake.

  Push the STOP button and move the spindle 

ON/OFF lever up to the OFF (middle) 
position to prevent accidental start-up.

  Remove the end gear cover from the left side 

of the headstock. There is a safety switch 
that prevents the spindle from starting while 
this cover is removed.

  Reset the STOP button, stand away from 

all the exposed gears on the side of the 
headstock, then attempt to start spindle 
rotation—the spindle should not start.

— If the spindle does start with the end gear 

cover removed, the safety limit switch is 
not adjusted or operating correctly. This 
safety feature must operate properly 
before continuing. Press the STOP button 
to turn the lathe OFF, disconnect it from 
power, and call Tech Support for help.

  Push the STOP button in, move the spindle 

ON/OFF lever to the OFF position, then 
replace the end gear cover.

  Reset the STOP button, then lift the chuck 

guard up—this will activate the chuck guard 
safety switch to prevent spindle rotation. 
Attempt to start spindle rotation—the 
spindle should not start. 

— If the spindle starts with the chuck guard 

in the up position, the safety switch is 
not adjusted or operating correctly. This 
safety feature must operate properly 
before continuing. Press the STOP button 
to turn the lathe OFF, disconnect it from 
power, and call Tech Support for help.

  Move the chuck guard back down into 

operating position.

  Point the coolant nozzle down into the chip 

drawer and verify that there is coolant in the 
reservoir (refer to Coolant System Service 
on Page 75 for detailed instructions).

  Use the coolant pump switch on the control 

panel to start the pump, then open the valve 
at the base of the nozzle. Verify that the 
coolant flows from the nozzle, then close the 
valve and turn the pump OFF.

Congratulations! The test run is complete. 
Perform the following Spindle Break-In 
procedure.
