Test Run

After all preparation steps have been completed,

the machine and its safety features must be

tested to ensure correct operation.

If you discover a problem with the operation

of the machine or its safety components, do

not operate it further until you have resolved

the problem. Refer to the Troubleshooting

section on Page 54 for solutions to common

problems that may occur with all mills. If you

need additional help, contact our Tech Support at

(360) 734-1540.

During the test run, you will verify the proper

operation of the following:

• Spindle motor

• Emergency STOP button

• Electrical cabinet safety switch

• Spindle brake

• Coolant pump

• X-axis power feed

To test run the machine:

Read and follow the safety instructions at

the beginning of the manual, take required

safety precautions, and make sure the

machine is set up and adjusted properly.

Operating the coolant pump of this mill

without the correct amount of coolant in

the reservoir could damage it and void the

warranty. ALWAYS make sure there is the

correct amount of coolant in the reservoir

before using the pump.

Clean out the coolant reservoir in the base of

the mill, then fill it with coolant (refer to the

Coolant System section on Pages 48–49

for specific details).

Clear away all tools and objects used during

assembly and preparation.

Rotate the spindle speed dial on the control

panel counterclockwise to the lowest setting,

the spindle direction switch to the STOP

(middle) position, and the coolant switch to

the OFF (left) position (see Figure 15). This

will disable these functions for now when the

power initially flows to the control panel in

the next steps.

Pulling the power plug

from the receptacle while

the mill is running could

damage the inverter

inside the electrical box

or other electrical parts.

Always use the emergency

STOP button or the circuit

breaker to turn the mill

OFF before pulling the

plug.
