  • Page 8: Electrical Connections

    Electrical Connections Electrical connections must be made by a qualified electrician in compliance with all relevant codes. This machine must be properly grounded to help prevent electrical shock and possible fatal injury. This machine must be grounded. In the event of a malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric shock.

    Belt Tension To adjust tension of the belts, open the rear panel and use the nuts (A) on the threaded shaft, shown in Figure 4, to either raise or lower the motor. Re-tighten nuts when satisfied. Proper tension is achieved when there is approximately 1/4”...

  • Page 10: Depth Of Cut

    Proper grinding done at the right time will do more than anything to prolong the life of knives. More dulling occurs in the last 20% of the useful life of the knife than in the other 80% of use. If the knives are sharpened on schedule and before the last 20% of possible use they can be resharpened with .002”...

    4. If the reading on the depth of cut scale is incorrect, loosen the two mounting screws on the clear plastic plate and adjust accordingly. The top scale (A, Fig. 8) is in English units, the bottom scale (B, Fig. 8) is metric.
  • Page 12 NOTE: If a bed and feed roll gauge is not available, use a finished block of wood with notches cut out for the table rollers, and a feeler gauge. See Figure 13 for an example of a wood block used as a gauge.) 2.
  • Page 13 Chipbreaker The functions of the chipbreaker are to break chips into small pieces, help avoid splintering of the wood, help avoid board bounce on thinner boards, and to direct the flow of chips out of the machine. The chipbreaker is factory adjusted to be 1/32” below the cutting arc of the knives.

  • Page 14: Leveling Cutterhead With Bed

    Leveling Cutterhead with Bed The cutterhead has been leveled with the surface of the planer bed at the factory. However, should future adjustment be needed, proceed as follows: 1. Place a bed and feed roll gauge (or wood block) beneath one end of the cutterhead. Crank the planer bed up until the cutterhead is just touching the gauge, and check the measurement.

  • Page 15: Operation

    Operation Kinds of Warp Warp is a variation from a plane or true surface. Warping of wood is caused by uneven shrinkage during the drying process. Shrinkage is not the same in all directions of the grain and due to the different grain direction in pieces of Figure 19 lumber, different types of warpage can occur.

  • Page 16: Depth Of Cut

    Depth of Cut The thickness of stock run through the planer is controlled by the distance you adjust the bed from the cutting knife. Always start your work by making a light planing cut. The depth of cut on subsequent passes may be increased, up to 1/8”, however, remember that a light cut creates a finer finish than a heavier cut.

  • Page 17: Introduction To Molding

    Introduction to Molding Pattern Knives Custom molding knives are ground from high speed hard steel. Your PM15 planer-molder will accept a single knife set, which uses gibs and counterbalances to ensure the cutterhead is in balance at all times. See Figure 24. It will also accept a three-knife set.

  • Page 18: Homemade Guide Set-Up For Edge Molding

    Homemade Guide Set-Up for Edge Molding Figure 27 shows a wooden guide set-up for edge molding. The guides are C-clamped on each side of the stock and are within 3/4” of the top edge to provide maximum support so that the narrow stock will travel beneath the knife.

    3. Mount the molding cutter gauge (A, Fig. 31) to the theaded hole in the casting with the socket head cap screw (B, Fig. 31). The guide may be attached to either side. 4. Adjust the gauge (A, Fig. 31) so that the end of it meets the pattern knife, then tighten the screw (B, Fig.

    1. To adjust the guides, lower the bed and place a board of correct width to be molded under the cutterhead. 2. Loosely adjust the guides to the board. Rotate the cutterhead by hand and see if the pattern knife will line up with the board. Adjust accordingly until the pattern knife and board are lined up as in Figure 33.

    If you have not already done so, install counterweights in the remaining two cutterhead slots. The rabbet knife is locked in place with the aluminum gib provided. NOTE: When the rabbet knife becomes dull on side, move rabbet knife counterweight set-up to the opposite side of the cutterhead.

  • Page 22: Maintenance

    Multiple Custom Knife Use Many operators who have continuous short runs of several different patterns save set-up time by installing more than one set of knives in the cutterhead at the same time. You can change from one pattern to another simply by changing the guides.

  • Page 23: Lubrication

    Lubrication 1. The recommended lubrication for roller chains used in medium to slow speed operation is to simply wipe the chain clean. When there is an appreciable build up of dust, dirt or wood shavings, use an oil cloth but never pour the oil directly on the chain. Over-oiling defeats the purpose of the lubrication, since it tends to invite the collecting of dust, shavings, etc.
