Bearing Preload
This lathe is shipped from the factory with the
bearing preload already set. If the preload
requires resetting for whatever reason, please
contact our service department for further
instructions.
Slides and Ways - Apply oil to the ways and
slides after each use. Wipe the ways with a clean
rag prior to lubrication to ensure that no grime is
carried along with your lubricant into friction-sen-
sitive areas. Applying oil to the bedways and
other bare metal parts also protect the lathe from
rust and pitting.
Lead Screw and Feed Rod - Be sure to clean
and lubricate the leadscrew, feed rod and switch
control rod. The lead screw and feed rod have a
bearing on the tail stock end support that will
require one to two squirts of oil.
See Figure 36.
Headstock Gearbox - The oil in the headstock
should be changed after the first 2 hours of use.
Then, every 6 months, depending on usage. It is
recommended that a light weight, non detergent
oil be used. Viscosity can range from 10W to
30W and may include multi-viscosity oil in this
same range.
Tailstock - The tailstock is fitted with one oiling
port. The tailstock barrel may be oiled directly.
Apply oil each week, or after every five uses
(depending on the frequency of operation). Be
sure to clean the slide ways for the tailstock and
lift the tailstock and squirt a few drops of oil on
the ways. It is a good idea to remove the tailstock
once a month and wipe the bottom thoroughly
and replace.
