MAINTENANCE
Lubrication
Figures 51—53 show lubrication locations that need
attention every six months; however, under heavy use or
adverse working conditions, increase lubrication intervals
accordingly.
Since all bearings are sealed and permanently lubricated,
simply leave them alone until they need to be replaced.
To lubricate the machine, do these steps:
1. DISCONNECT MACHINE FROM POWER!
2. Measure and record the distance each tensioner
protrudes from the top of the headstock.
3. Loosen the nuts and un-thread the tensioner
assemblies, one of which is shown in Figure 51.
4. Clean the tensioner assembly with mineral spirits,
apply a thin layer of light machine oil or motor oil,
and reinstall the tensioner to the previously recorded
height.
5. Place the nozzle under the chain housing, vacuum
out all dust, then brush a coat of light machine oil or
motor oil on the drive chains (see Figure 52).
6. Clean the column ways and leadscrew with mineral
spirits, and brush a coat of light machine oil or motor
oil on all cleaned locations (see Figure 53).
7. Apply a few drops of light machine oil or motor oil
onto the gib at the top, so the oil drains down inside
the gib seat, keeping the gib lubricated.
8. Apply a few drops of light machine oil or motor oil
onto the handwheel scale hub, and work the hub to
make sure that it draws the oil down inside.
9. Wipe away excess oil with a clean rag.
