New Belt Replacement
Posted: Sat Feb 25, 2012 11:07 am
This is in response to several questions I have received recently. Any time you replace the motor belt, any sheaves and/or the Speed Control Assembly quadrant, you may have difficulty reaching the SLOW speed control position or having a full speed range from SLOW to HIGH.
With the belt replacement, It should get harder as you move the speed toward the lower end of the speed range. So, I try to limit the low end speed at "C" at the low end until you get some hours on the belt. Do not force the handle toward SLOW and take your time when going from FAST to SLOW (1/4 the speed then going to HIGH). Also you have to break in the meshing of the speed control quadrant and worm gear.
If you are unable to get a full speed range from SLOW to FAST after a break-in time, then you will need to increase the HIGH Speed Adjustment until you obtain the full range of speeds. Always manually rotate the quill after any HIGH Speed Adjustment before applying power to insure the Control Sheave is not hitting the Speed Control Assembly body.
