Test Run

Once assembly is complete, test run the machine to ensure it is properly connected to power and safety components are functioning properly.

If you find an unusual problem during the test run, immediately stop the machine, disconnect it from power, and fix the problem BEFORE operating the machine again. The Troubleshooting table in the SERVICE section of this manual can help.

Serious injury or death can result from using this machine BEFORE understanding its controls and related safety information. DO NOT operate, or allow others to operate, machine until the information is understood.

DO NOT start machine until all preceding setup instructions have been performed. Operating an improperly set up machine may result in malfunction or unexpect- ed results that can lead to serious injury, death, or machine/property damage.

To test run mill/drill:

1.Make sure all tools and objects used during setup are cleared away from machine.

2.Press OFF button (see Figure 16). This will help prevent unexpected startup when machine is connected to power.
