G9729 Combination Lathe/Mill
-51-
Lubrication
Your Model G9729 will function best when it is
clean and well lubricated. Take the time to wipe
down and oil the machine before each use. We
recommend using ISO 68 or SAE 20W non-
detergent oil unless otherwise specified. Ball fit-
tings
will require the use of an oil gun. Press the
ball with the tip of the gun and squirt a little oil
under pressure. Wipe the ball fitting before and
after each use to prevent contamination.
Apron and Cross Slide: Apply lubrication direct-
ly
to the dovetail ways of the apron and cross
slide.
Figure 68. Oil ports indicated by arrows.
Compound: This slide is supplied with ball fit-
tings on its top surface and should be oiled at the
same time as the apron (Figure 68).
Bearings: Lubrication for the internal gears
occurs as the machine runs and oil circulates
from the gear box. However, the bearings should
be lubricated through the ball fittings indicated
by the arrows in Figure 70. Apply
oil every 3
hours of actual use and just before starting the
machine each day.
External Gearing: Apply only a minimal amount
of oil to the teeth of the end gears after assembly
or each day. Note—Avoid getting oil on the belt
or pulleys when lubricating.
Remove
the gear in Figure 69, and apply a few
drops
of oil to the bushing once a day.
