Figure 130. Locations of headstock fill and drain
plugs.
To change headstock oil:
1. DISCONNECT MACHINE FROM POWER!
2. Remove end gear cover.
3. Remove V-belts so that oil does not get on
them, necessitating their replacement (refer
to the V-Belt Tension & Replacement on
Page 89 for detailed instructions).
4. Remove fill plug to allow oil to drain more
freely.
5. Place a funnel and a 2-gallon catch pan
under drain plug, then use 8mm hex wrench
to remove drain plug.
6. When headstock reservoir is empty, replace
drain plug and clean away any spilled oil.
7.
Fill headstock reservoir until oil level is
approximately halfway in sight glass, then
replace fill plug.
8.
Replace and retension V-belts, then secure
