Due to high voltage and risk of serious
shock involved, we strongly recommend
this procedure be done by an electrician or
qualified service personnel.
— If spindle rotates from left to right (as stand-
ing in front of machine), phase polarity of
incoming power supply is reversed. Stop
spindle and DISCONNECT MACHINE
FROM POWER! Remove electrical panel
cover, swap wires at L1 and L3 terminals
(see
Figure 12) then re-install electrical
panel cover and reconnect machine to
power.
8. Press EMERGENCY STOP button to turn
machine
OFF, then, without resetting the
EMERGENCY STOP button, try to restart
spindle rotation. Spindle should not start.
— If spindle rotation does start with
EMERGENCY STOP button pressed in,
EMERGENCY STOP button safety is not
operating correctly. This safety feature
must operate properly before continuing
operation. Turn master power switch to
OFF position, disconnect machine from
power, and call Tech Support for help.
9. Twist EMERGENCY STOP to reset, and
press Spindle Stop Button. Open chip guard
to activate safety switch, which should pre-
vent the spindle from starting.
10. Attempt to start spindle rotation. Spindle
should not start.
— If spindle rotation does start with chip
guard open, safety switch is not operating
correctly. This safety feature must oper-
ate properly before continuing operation.
Turn master power switch to OFF position,
disconnect machine from power, and call
Tech Support for help.
11. Close chip guard.
12. Aim coolant nozzle into trough, and use cool-
ant pump switch on control panel to start
pump (see
Figure 11 on Page 18).

13. Open ball valve (see Figure 13). Verify cut-
ting fluid flows from nozzle, then turn pump
OFF and close ball valve.
Congratulations! The test run is complete. Perform
the following
Spindle Break-In procedure.
If pump is running, ball valve is open, and
no coolant is flowing from coolant nozzle,
this is an indication of inadequate coolant
levels in reservoir. Immediately turn pump
OFF! Running pump without adequate cool-
ant can lead to pump damage, which will not
be covered under warranty.
