Adjustments Tools required: Philips screwdriver Hex wrenches (provided) Open-end wrench (provided) Depth of Cut Depth of cut is controlled by raising or lowering the table. This is done by using the handwheel (A), shown in Figure 4. 1.

Opening Hood To open the hood for access to the cutterhead, remove the two hex screws with the 22mm wrench provided. See Figure 7. Knife Installation and Adjustment (Straight Cutterhead only) Use care when placing hands near knives as they are extremely sharp and can cause severe cuts. Installing knives on a planer is an exacting Figure 7 process. If the knives are not to be jointed and ground, end-to-end and knife-to-knife relationship must be held within .001" (.03mm)

7. Rotate the cutterhead using the belt or pulley, and repeat steps 2 through 6 for each of the remaining three knives. 8. When all four knives have been installed and made snug, begin the tightening process. NOTE: All knives and gibs should be in place before tightening. Tightening one knife in without the others in position can cause cutterhead distortion. 9. The tightening process should proceed working from the center outward on each knife. Go once around the cu

6. If it is not 1/16” below the knife, correct by loosening the hex nut and turning the adjustment screw (A, Figure 14) with a hex wrench. 7. Move the gauge to the extreme right end of the infeed roller and check. Make similar adjustments if needed. 8. Tighten hex nuts (A, Figure 14) when finished. IMPORTANT: The setting on both ends of the infeed roller must be the same to avoid skewing of the material as it is fed through the machine. Chipbreaker Figure 13 The chipbreaker is a

Outfeed Roller The outfeed roller is of smooth, one-piece construction to help avoid marring the finished surface of the material being cut. It is spring tensioned, and its function is to continue to feed the material through the machine after it leaves the infeed roller. The correct free position setting is 1/32" (0.8mm) below the arc of the cutterhead knives. Use a gauge, such as a bed and feed roll gauge or wood gauge block (see Figure 13) to check the outfeed roller in the sam

5. If the gauge reading is greater or less than zero, reach beneath the table with a wrench and loosen the hex nut (C, Figure 17) which is above the cam (D, Figure 17) near the end of the roller that needs adjusting. Rotate the hex cap screw (E, Figure 17) until the gauge reads zero. 6. Repeat the process for the left side of the table roller, and then re-check the right side. It is important that both ends of the table roller be the same height to help prevent skewing of the board as

Operating Controls The stop button is a mushroom style button which is convenient for “emergency” shutdowns. After being pushed, the stop button remains engaged. To re-start the planer, twist the stop button clockwise until it pops back out. Test Cutting and Troubleshooting Using a piece of semi-finished stock, set up for a 1/16" (1.59mm) deep cut with the quick-set table roller adjustment (shown in Figure 16) set at zero.

Snipe Some amount of snipe may be inevitable with many planer operations, but proper planer adjustments can so minimize snipe as to make it negligible. If noticeable snipes appear on each end of the Figure 22 material, as shown in Figure 22, a table roller is (snipe) too high causing a slight lift of the material as it passes through the machine. Normally these snipes are more noticeable on the trailing end of the board than on the lead end, and most often occur during planing
