Figure 32 19 Figure 33 Gearbox Referring to Figure 34: The JWP-16OS Planer is equipped with a spiral, serrated infeed roller (F) and a solid outfeed roller. When the feed rollers are engaged, they turn to feed the stock. The feed rollers are driven by chains (A) and sprockets (B) in the gearbox. The gearbox is located on the right side of the planer directly behind the table lock knob (A, Fig. 35). The gearbox transfers power from the belt-driven cutterhead to the power feed rollers. A two-speed transmission, controlled by a push/pull lever (D), moves the stock through the planer at either 16 or 20 feet-per minute. The push/pull lever is set while the machine is running. Figure 34 Operation The JWP-16OS Planer is a powerful woodworking machine, designed and constructed for professional-quality applications. Because of its powerful motor and razor- sharp knives, the JWP-16OS Planer is inherently dangerous and should be operated with considerable caution and respect. Failure to do so could result indamage to the machine or severe injury to the operator or others in the work area. Overview There are a number of safety issues that relate directly to the operation of the planer. Keep in mind that these are not all-inclusive. Work situations, wood types, and other variables that differ from shop to shop must be considered in order to operate this planer safely. Always consider safety and common sense first when operating this or other machinery. 1. Always inspect lumber for defects (warping, cupping, twisting, etc.). Do not use lumber of questionable quality. 2. Check lumber for nails, staples, imbedded gravel, etc. before planing. 3. Use the full width of the planer. Alternate between the left, the right and the middle when feeding lumber into the planer. Your knives will remain sharp much longer. 4. Remove glues, epoxies and other foreign matter before planing lumber. 5. Never attempt to plane laminates, particleboards, plastics or other man-made materials. 6. Plane wood with the grain. Never plane across the grain. 7. Do not use boards with loose knots, splits, cross grain or other defects. They can damage the machine and cause injury. 8. Keep your work area clear. 9. Wood with excessive water content or wood exposed to rain, ice, or snow will plane poorly and cause excess wear to the knives and motor. Excessive moisture will also hasten rust and corrosion. 10. Learn as much as possible about planing procedures. Alternative publications present more wood specific planing requirements. Table Locks Before attempting to adjust table height, loosen the two table lock knobs, one on the right front of the head casting assembly (A, Fig. 35) and the other on the left rear. 20 Figure 35 After the head assembly height is adjusted, tighten the two black knobs down again. Power Feed Referring to Figure 36: The power feed features two feed rates, 16 FPM and 20 FPM. When running the machine, the operator can control the feed speed by moving the feed control knob. Moving the knob toward the machine produces the 20 FPM feed speed (A), away from the machine produces 16 FPM (C) and a center position places the gear box in neutral (B). Figure 36 Set the feed rate while the planer is runningbut before feeding lumber into it. DO NOT change speeds after the cutting operation has begun. If the cut is too large, the planer will slowdown considerably, possibly even stallingthe motor. Turn off the power immediately, raise the head assembly and remove the workpiece. Re-adjust the head assembly to allow a lesser cut and repeat the operation. Handwheel Crank the handwheel to raise or lower the table according to the desired workpiece thickness. Each complete revolution of the handwheel moves the head assembly by 0.158” (4mm). Make sure the height scale is properly adjusted. With the depth-limiting clip installed, you cannot cut full width more than 1/8" in a single pass (3/16" if lumber can fit on either side of the depth limiting clip). While cutting this much material is possible, it is not recommended. Depth Limiter The Model JWP-16OS Planer is equipped with a depth limiter – located on the bottom of the cutterhead casting just below the warning label (A, Fig. 37). The depth limiter controls maximum depth of cut to 1/8". Figure 37 To avoid mechanical damage to the planer, do not remove the depth limiter. Initial Startup After the assembly and adjustments are complete the planer is ready to be tested. Turn on the power supply at the main panel. Press the Start button.
