MAINTENANCE
Verifying Oil Pump Operation
To prevent costly damage to the headstock
gears and bearings, a kill switch will shut the
lathe down if the oil pump stops working or the
oil level is becomes too low. Verify the pump is
working by looking at the sight glass shown in
Figure 98. When working correctly, oil flows
across the sight glass.
Changing Headstock Oil
To ensure proper lubrication of headstock gears
and spindle bearings, the headstock oil must
be changed and the oil system cleaned after
the Spindle Break-In (refer to Page 28) and
annually thereafter (or every six months with
heavy service or extreme working conditions).
Items Needed Qty
Oil Catch Pan (5-Gallon) ......................................1
Flexible Oil Funnel w/Hose ..................................1
Wrench 12mm .......................................................1
Mineral Spirits ......................................As Needed
Shop Rags ..............................................As Needed
To change the headstock oil:
1. Run the lathe at a medium speed for at least
10 minutes to warm the headstock oil.
2. DISCONNECT LATHE FROM POWER!
3. Put on safety goggles, rubber gloves, and
a respirator to protect yourself from the
contamination hazards of the oil.
4. Remove the side and rear motor access
covers and the end gear cover.
5. Remove the three V-belts (refer to V-Belts
on Page 77 for detailed instructions).
6. Remove the oil cap from the top of the
headstock (see Figure 99). This allows the
oil to flow freely from the headstock in the
next step.
7. With the help of an assistant, hold the
flexible oil funnel and hose under the
headstock oil drain plug and point it into
the catch pan as you remove the drain plug.
This will remove the standing oil in the
headstock.
Tip: To eliminate the need to remove the V-belts
when repeating this procedure in the future,
install a
1
⁄2" pipe of appropriate length and
a cap in the place of the headstock oil drain
plug. Make sure this pipe will not interfere
when re-attaching the end gear cover.
