-15-
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.
Failure to follow start up and spindle break-
in procedures will likely cause rapid deteri-
oration of spindle and other related parts.
NOTICE
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.
