Test Run and

Spindle Break-in

The Model G0463 has two speed ranges: Low range is 0–1000; high range is 0–2000 RPM.

It is essential to closely follow the proper break-in procedures to ensure trouble free performance. Complete this process once you have familiarized yourself with all instructions in this manual.

To begin the start up and break-in procedure:

1. Follow all lubrication procedures highlighted in Lubrication in Section 6: MAINTENANCE on Page 24.

2. Make sure there are no obstructions around or underneath the spindle. Remove the drawbar if there is no arbor or collet in the spindle.

3.With the spindle at a complete stop, shift the HIGH/LOW gear change knob into the low range (see Figure 7). Set the forward/ reverse switch to FWD.

Note: If the knob will not rotate into gear at first, rotate the spindle by hand while holding light pressure on the knob. When the gears engage, the knob will rotate into place.

4.Make sure all switches are OFF and connect the mill/drill to the power source.

5. Turn the main power switch ON & Spindle RPM control ON and let the mill run for a minimum of 10 minutes on a low speed. The mill/drill should run smoothly with minimal noise and vibration.

—If you suspect the mill/drill is not working correctly, shut the mill/drill OFF and correct the problem before proceeding further.

—If the mill/drill is running smoothly, pro- ceed.

NOTICE

DO NOT attempt to change between high and low speed ranges with the spindle ON. Damage to the spindle gearing will occur.

6. Slowly increase the RPM and allow it to run at a medium RPM for another ten minutes.

7.Slowly increase the RPM and allow it to run at a high RPM for another ten minutes.

8. Turn the mill/drill OFF. Switch to the high range and repeat Steps 4–6.

9.Set the forward/reverse switch to REV and repeat the previous process.

NOTICE

Failure to follow start up and spindle break- in procedures will likely cause rapid deteri- oration of spindle and other related parts.
