Bearing Preload - Grizzly G4002 Owner's Manual

Slides and Ways: Apply iso 68 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 fric-
tion-sensitive areas. Applying oil to the bedways
and other bare metal parts also protects the lathe
from rust and pitting.
Apron: Use grizzly t23962 or an iso 68 equiva-
lent. the drain plug is located underneath the
apron. the fill plug is located on top of the apron.
Add oil until the oil level is in the middle of the site
glass, which is located on the face of the apron.
Saddle, cross Slide and compound ball
Oilers: Add 1-2 drops of oil to the ball oilers
shown in figure 43.

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 44.

Ball oilers
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. see figure 45.
