changing Oil
the oil in the reservoirs must be changed after
the first three months of operation, then twice a
year after that. if the lathe is under heavy use,
more frequent oil changes will be required to keep
the gearboxes clean and ensure long machine
life. some lathe owners believe that by using full
synthetic oils in the gearboxes is a way to extend
oil change intervals. We do not recommend this
practice. While synthetic oils are superior this lathe
does not use a filter to remove contaminants that
are generated during normal use, such as when
shifting gears. Changing the oils on a frequent
basis to flush out moisture and contaminants is
still the best option to ensure long gearbox life.

To change the oil in the reservoirs:
1. run the lathe to bring the lathe gearboxes to
a warm temperature and turn OFF the lathe.
2. disConneCt lAthe FroM poWer!
3. remove the headstock gear cover.
4. using a funnel or cardboard ramp if desired
to direct waste oil into the drain pan, position
the drain pan under the gearbox drain plug.
5. remove the fill plug and the drain plug from
the selected oil reservoir, and allow all oil to
drain.
6. re-install the drain plug, add oil to the res-
ervoir until the sight glass reads full. then
re-install the fill plug.
v-belt Tension
After initial break in, the v-belts slightly stretch
and seat into the pulley. it is important to check
and adjust them to compensate for this initial
wear. Check the tension thereafter on a monthly
basis.

To check the v-belt tension:
1. disConneCt lAthe FroM poWer!
2. remove the headstock gear cover.
3. push the center of the v-belts with moderate
pressure. the v-belt deflection should be
approximately
1 ⁄
4
