Although not required, we recommend using a Rotacator® for the following setup. Check with the current Grizzly catalog for details. To set the feed rollers and pressure bar with hardwood blocks: 1. Make sure the machine is disconnected from power and the knives have been adjusted properly! 2. Obtain a milled piece of hardwood that is within .002" from one side to another. Rip this piece down the middle. (Two separate boards may also be used if they are within .002" of each other in thickness.) 3. Lower the table rollers below the surface of the table and lock the cutterhead in place. 4. Place the boards on each side of the table as shown in Figure 15, so each board spans from the front of the table to the back. Hardwood Blocks Figure 15. Board position on table. Extreme Duty Planers 6. Open the left cabinet door. Loosen the check nuts shown in Figure 16, and turn the adjustment bolts to raise each block up approximately 1.2" (enough to be above the horizontal plane of bottom dead center of the cutterhead knife/insert). Roller Blocks Check Nuts Adjustment Bolts 7. Open the right cabinet door. Loosen the check nuts shown in Figure 17, and turn the adjustment bolt and setscrew to raise each block the same amount as those from the previous step. Figure 17. Right side roller controls.

Place a piece of newspaper on each wood block so it is both under the cutterhead and accessible from the back of the planer. The newspaper will act as a feeler gauge to help you know when the table is high enough. (Newspaper is about .003" thick and is long enough for adequate access.) 9. Raise the table close to the knife/insert edge. Continue raising the table with the micro adjust knob while constantly checking for resistance on the newspaper. When you get a medium drag on the paper, stop raising the table and remove the newspaper. This table position will now be your reference point from which to make the other adjustments. 10. Lower the feed rollers so they rest on the wood blocks. Back the adjustment bolts out another 1.8" (approximately). 11. Notice where the hairline indicator reads on the table height scale. With the micro-adjustment knob, lower the table approximately 1mm on the scale (1mm = .039"). 12. On the right and left sides, raise the adjustment bolts up to the roller blocks and tighten the check nuts. Make sure the adjustment bolts do not move while tightening the check nuts. 13. Rotate the pressure bar down to its original position. On the pressure bar, back the stop bolts out enough so that the pressure bar rests on the wood blocks below. 14. Set the stop bolts so they barely touch the planer body and tighten the check nuts to keep them in place. 15. Replace the springs and nuts. Tighten the nuts down on the tension stud so that the top of the nut is approximately 1.4" from the top of the tension stud. To set the feed rollers and pressure bar with a Rotacator®: 1. Make sure the planer is disconnected from power and the knives are adjusted properly. 2. Read the previous instructions about setting the feed rollers and pressure bar with wood blocks—this will familiarize you with how to access and adjust the feed rollers and pressure bar. 3. Engage the cutterhead lock. 4. Place the Rotacator® on the table, underneath the cutterhead. Line up the Rotacator® plunger on the edge of the knife. Set the dial to .000" and lock in place. 5. Move the Rotacator® directly under the one side of the feed roller and set the plunger on a bottom dead center edge. Adjust the feed roller until the Rotacator® reads .040". 6. Repeat step 4 on each end of each feed roller. Double check for accuracy, then lock the check nuts in place. 7. Adjust the pressure bar using the same procedure as with the feed rollers. -30- Extreme Duty Planers Feed Roller Tension The feed roller spring tension is factory set and should require no initial adjustments, unless needed for a special type of stock. If a situation develops where the workpiece does not feed straight, adjustments to one roller may be necessary. Usually if the board is moving to one side, that side needs more pressure. Open the left cabinet door and locate the spring above the feed block (directly above the adjustment bolt from the previous instructions). Turn the nut counter-clockwise to increase the spring tension. In general, rough stock or deeper cuts require more feed rate pressure (more spring tension). Shallow cuts need less feed rate pressure. Too much pressure increases snipe. Find a balance that is right for your application. Chip Deflector The segmented chip breaker is factory set for height, so the only adjustment that can be performed is to the spring pressure. To adjust the pressure on the chip breaker segments: 1. Make sure the planer is disconnected from the power source! 2. Rotate the knurled adjustment rings shown...
