Bearing Preload - Grizzly G4015Z Owner's Manual

Motor - The bearings used in the motor are
shielded and lubricated for life, therefore, no
lubrication is necessary.
Lead Screw - Be sure to clean and lubricate the
Lead Screw. There is also a bearing on the tail
stock end that will require oil.
Headstock Gearbox - The oil in the headstock
should be changed after the first 2 hours of use,
then every 6 months, depending on usage. We
recommend 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.
To remove the oil in the gear box, remove the
change gear directly under the spindle, remove
the cap screw indicated in Figure 55 and place
a can under the drain hole to collect the waste
oil.

Tailstock - The tailstock is fitted with 2 oiling
ports. 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 tail-
stock, once a month and wipe the bottom thor-
oughly and replace. See Figure 55.
