Why 3ph motor will work in reverse direction?
no Under most conditions the answer would be no, however I experienced this very occurrence myself. This is the condition it happened under: Wiring a three phase power band saw with a hydraulic pump. The pump was used to clamp the work in place and raise the cutting head. One of the wires for the pump motor had come out of the factory installed terminal strip. When the saw was started the pump ran in reverse, we changed the rotation at the disconnect. Started the pump again, the pump again ran in reverse. Thinking we had reconnected it incorrectly, we again changed the phasing. Started the pump again, again it ran in reverse. We started looking the wiring over and found the wire out of the terminal strip, corrected this problem and the motor ran in the right direction. Why did this happen? A three phase motor will run with only two phases connected as long as there is no load on the motor. The pump only loaded the motor when it was turning in the right direction and pumping oil. The pump provided no load when turning in reverse and the motor could easily turn it.

Will a 7500watt generator start a 2hp 15amp electric planer?
Use this formula W = A x V . Assuming that the saw is using 120 volts. 15 x 120 = 1800. Start up current on a motor will draw up to 300 % instantaneously so a 2000 watt generator might just do it. It would lug at the start but then catch up and run the saw. On motor from generator uses higher wattage is better.
What checks do you need to carry out to make sure all the materials that are required are correct and complete before starting the activity?
Select right grade of steel/ material check it in reference chart. Cut material (on band-saw) with excess so that it is longer than its required length. (that is because band-saw doesn`t cut straight edge and in any case it will have to be faced) (I am not the best person to answer but this is better than unrelated stuff that people write)

Does the manufacturing logo on a circular saw blade always face out toward you?
Depends on the manufacturer and if the saw is left or right handed. Normally a saw cuts UP rotating in the opposite direction a wheel would. Click the saw on, without a blade in to see which way the motor turns then put the blade in to cut in that direction.
What do you do to reverse your skill saw from backwards to forwards?
Not sure I fully understand the question, but the blade should always cut clockwise, or on the downstroke. The motor is set to run in that direction and the blade is configured to cut in that direction. Any other direction would be dangerous for the user an just imagine where all the saw dust would be going
