Once the assembly is complete and the adjust- ments are done to your satisfaction, you are ready to test the machine.
Turn on the power supply at the main panel. Press the START button. Make sure that your fin- ger is poised on the STOP button, just in case there is a problem. The planer should run smoothly, with little or no vibration or rubbing noises. Strange or unnatural noises should be investigated and corrected before operating the machine further.
WARNING
DO NOT attempt to investigate or adjust the machine while it is running. Wait until the machine is turned off, unplugged and all working parts have come to a rest before you do anything!
If noises occur that cannot be found by visual inspection, feel free to contact our service depart- ment for help.
WARNING
Always wear
The species of wood, as well as its condition, have a dramatic effect on planing ability. The harder the wood (as illustrated by its shear strength), the more difficult it will be to plane. A brief listing of common hard and soft woods in relation to their shear strengths and planing diffi- culty is listed below.
