Grizzly G4002, G4003 instruction manual Bearing Preload

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. See Figure 37.
