Figure 98. Locations of headstock fill and drain
plugs.
To change headstock oil:

them, necessitating their replacement (refer

4. Remove fill plug to allow oil to drain more
freely.

under drain plug, then use 8mm hex wrench

6. When headstock reservoir is empty, replace
drain plug and clean away any spilled oil.
