Your shaper operates at speeds of 3600, 5100, 8000 and 10,000 R.P.M. 31⁄2" or larger cutters must be operated at the slowest speed.
Always use the largest spindle size possible, and never use more than one bushing size to gain two spindle sizes. ”Stacking” two cutter bushings to decrease the inside diameter of the cutter will cause the cutter to perform incorrectly when placed under a load.
1.Unplug the shaper.
2.Place an appropriate spacer or collar at the base of the spindle for support. Place the cutter on the spindle, making sure the rota- tion is correct for your application.
3.Use spacers or collars to suit your particular application, then place the spindle washer under the nut. Screw on the nut and locknut.
4.Tighten the nuts while holding the spindle stationary. Use a wrench on the notches at the top of the spindle for leverage as shown in Figure 31.
The sliding table works with the clamping miter gauge to allow you to secure your workpiece to the table and make the cut by sliding the table. This feature greatly increases operator safety because it keeps hands away from the cutter- head.
When the sliding operation is not desired, the table lock shown in Figure 32 will make the table stationary. Simply pull the knurled shaft and twist it so the cross pins slide into the largest slots in the housing. If you want to unlock the table, pull the shaft, twist it, and place the cross pins in the smallest slot.

Always use a spindle lock nut during oper- ation. If this warning is ignored, the cutter may fly off the spindle during use and cause severe personal injury.

The sliding table makes it easy to feed the work into the cutter at a faster rate than would normally be used. Always feed the work slow and steady to avoid kickback and to achieve smooth results with your work. Although the miter assembly does aid in safety, common sense should always be used during every shaping operation.
