NOTICE NEVER shift lathe gears when lathe is operating, and make sure both the half- nut lever and the feed selection lever are disengaged before you start the lathe! Otherwise the carriage may feed into the chuck or tailstock and cause severe damage.
Page 24
Spindle Break-In NOTICE Do not place this machine into service and subject it to normal work loads until it is completely broken-in and the gearbox oils have been changed! Otherwise, bearings can improperly seat, and gears can develop excessive backlash and result in vibration or noisy operation.
OMMEND that you read books, trade maga- zines, or get formal training before begin- ning any projects. Regardless of the con- tent in this section, Grizzly Industrial will not be held liable for accidents caused by lack of training. Operation Overview...

Cutting Fluid System BIOLOGICAL AND POISON HAZARD! Use the correct personal pro- tection equipment when handling cutting fluid and by follow federal, state, and fluid manufacturer requirements to properly dispose of cutting fluid. Tip: For speedy chip removal from the tank, a metal catch basket with handles can be made to lift out the metal chip buildup in the first chamber.
Gib Adjustments NOTICE When adjusting gibs, keep in mind that the goal of gib adjustment is to remove unnec- essary sloppiness from the slide without causing binding and excessive half nut wear. Tip: The compound and cross slide gibs have a gib lock screw that are shown in Figures 95 –96.
Compound Slide Gib Figure 96 Figure 96. Saddle Gib IMPORTANT: Do not loosen the more than a couple of turns or the components inside will come apart. Reinstalling these compo- nents is difficult and time consuming. Figure 97. Figure 98. Tools Needed Figure 97 To adjust the saddle slide gib:...
