CTP 2S4638 Standard Fan for Models 633C, 637, 988, D8H
CTP Improved fuel efficiency, up to 1.5% depending on the application and duty cycle || Individually reverse each blade by simply pushing inward (towards the hub) to compress the spring and then begin to rotate the blade; it should only turn in one direction || Once the blade begins to rotate, you no longer need to keep pushing inward; continue to turn the blade toward the desired position; continue to reverse the remaining blades so that they are all in the same position || Once the blade is rotated fully to the desired position, the blade will "spring" outward and lock itself into place; Now the blade will not be able to be turned around without pushing it inward again; The reversing of one blade is now complete || Now that all of the blades have been reversed, the fan will force the air in the opposite direction; You are now ready to re-install the guarding, unlock the ignition switch, and continue operating the equipment with increased comfort
