Planer components. Table Cutterhead Chip Breaker Rear Feed Roller Front Feed Roller Anti-Kickback Claw Pressure Bar Bed Rollers Bed Roller Height Lever Extreme Duty Planers Cutterhead Knives The Model G9740/G9741/G9967 features a 4knife cutterhead. The knives are factory set to .071". Unless you are having problems related to the knives or are removing them for sharpening/ replacement, assume that your knives are adjusted correctly. To be safe, always test the planer with a scrap piece of wood before using expensive stock. When adjusting, make adjustments accurate to within ±.001" from one side to the other. Improperly adjusted knives can unbalance the cutterhead and shorten the bearing life, as well as produce substandard planing results. Planer knives are danger- ously sharp! Use extreme cautionwhenworking nearcuttingsurfaces. Failure to exercise care while working near knives could result in severe injury. To inspect the knife set: 1.Make sure the planer is disconnected from the power source! 2.Open the top cover to gain access to the cutterhead. Lock the cutterhead in place with the cutterhead lock as shown in Figure Cutterhead Lock Figure 7.Engaging cutterhead lock. 3. Remove the hex nuts and springs from the tension studs shown in Figure 8. This will allow the pressure bar to rotate up and over the cutterhead. 4. Remove the four bolts that attach the pressure bar to the eccentric ring. Pressure Bar Tension Studs 5. Without bumping the knife edge, carefully take the pressure bar out of the planer. You can now access the cutterhead with the knife setting jig. 6. To prepare the knife setting jig, back all four of the screws out of the feet. Adjusting one screw at a time, set the screw even with the surface of the jig foot. Turn the screw exactly 21.2" turns (this is approximately .071"), or measure this distance with a caliper. Tighten the check nut, making sure that the screw does not move. Adjust the other three screws by using this same procedure. 7. Place the jig on the cutterhead. If the knife is adjusted right, the feet should touch the cutterhead body on both sides of the knife, and the knife should barely touch the jig. 8. Repeat this inspection for the other two knives. To adjust the knife set: 1. Before beginning, make sure you have followed steps 1-6 from the knife inspection instructions above! 2. Make sure the planer is disconnected from the power source! Extreme Duty Planers -23 3. Wear heavy leather gloves or place a rag over the exposed knife to protect your hands if the wrench slips while loosening the gib bolts. Loosen all the gib bolts on one knife. 4. Insert a 4mm hex wrench into the jack screws (accessible from holes in the cutterhead) as shown in Figure 9. Turn these screws to lower the knife enough to clear the jig when it is placed on the cutterhead body. Figure 9. Adjusting knife jack screws. 5. Turn the jack screws with the hex wrench to raise the knife so it barely touches the jig. Perform this adjustment on both ends. 6. Tighten the gib bolts on each side just enough to keep the knife from moving—DO NOT fully tighten at this time. 7. Repeat steps 2-6 on the other three knives, then move on to step 8. 8. Tighten the gib bolts, with medium pressure, in this order: (1) The two center bolts on each of the four knives, (2) the next two bolts outward from the center of each knife, and (3) the rest of the gib bolts in this manner until all bolts on all four knives have been tightened with medium pressure. 9. Now final tighten each of the bolts in the same manner as step 8. Tightening the gib bolts two at a time, each knife at a time, will prevent distortion of the cutterhead from over-torquing the gib bolts. 10. Replace all of the removed planer parts and adjust the pressure bar (pages 17-18) before operating the planer. Aftermarket Knife Setting Jigs To ease the knife adjustment process, consider using a Planer Pal® available in the current Grizzly catalog. Using magnets, a pair of these devices will automatically hold the knife blades within .001" of each other, thereby allowing you to quickly and accurately lock the knife in place. Carbide Cutters The Models G9740Z/G9967Z/G9961 feature spiral cutterheads. These spiral cutterheads cut with indexable carbide inserts which have four cutting edges. Although only one edge can cut at a time, the inserts can be easily rotated when they get dull, essentially providing four factory sharp edges before requiring replacement. Indexable inserts never need to be adjusted for height, only rotated and securely fa...
