D Installing Blades-Power Down Feed - Scotchman CPO 350 Manual

7.2D INSTALLING BLADES (POWER DOWN FEED)
SEE FIGURE 17 ON THE FOLLOWING PAGE.
Ö
CAUTION: USE ONLY HIGH SPEED STEEL BLADES DESIGNED FOR THIS MACHINE. DO
NOT MODIFY ANY BLADE TO FIT THIS MACHINE. DO NOT USE BLADES DESIGNED FOR
THIS MACHINE ON ANY OTHER EQUIPMENT.
The CPO-350 saw is designed to use a maximum 14 inch (350mm) diameter blade. The arbor size is
40mm with four 12mm pins spaced at 64mm.
Ü
BEFORE INSTALLING THE BLADE, make sure that the power to the machine is disconnected.
USE THE FOLLOWING STEPS TO INSTALL A BLADE:
(An 8mm hex key wrench (A), shipped with each machine, is required to change blades.)
1. Release the upper stroke control and allow the head to travel to its full UP position.
2. Raise the movable section of the guard (B) to the OPEN position.
3. Remove the blade bolt (C) through the center hole in the blade guard.
4. Remove the blade flange (D).
5. Install the blade. Make sure that the pin holes line up to the holes in the spindle.
6. Replace the blade flange and start the bolt into the spindle.
7. Before locking the blade in position, the back lash must be taken up. To take up the back lash,
rotate the bottom of the blade toward you until it seats against the drive pins.
Ö
CAUTION: THE BLADES ARE VERY SHARP AND CARE MUST BE TAKEN WHEN
REMOVING THE BACK LASH. DO NOT GRIP THE CUTTING EDGE OF THE BLADE BARE
HANDED. THE BACK LASH MUST BE TAKEN UP EVERY TIME A BLADE IS CHANGED.
8. After taking up the back lash, tighten the blade bolt (C).
9. Return the movable guard to the DOWN position and re-set the upper stroke control.
10. Break in the saw blade. The teeth on new or re-sharpened blades have a sharp edge and should be fed
through the first three or four cuts, very slowly, before starting normal cutting. Besides taking up the
back lash and breaking in the blade, it is very important to keep the blade flange, the spindle and the
blade clean and free from nicks. Failure to do these things will result in broken or damaged blades.
