11. ADJUSTING THE BLADE GUIDES
The Upper Blade Guide
A. To adjust the upper blade guides, first position the right and left roller guides relative to the blade by loosening the lock nut (FIG. 19) and moving the guide carrier until both roller guides are approximately 1/16” behind the gullets of the saw blade.
B. Set both roller guides to within 1/32” of the saw blade by releasing the guide adjusting screw (FIG. 19) on each side of the saw blade and moving the guides to desired position. Lock the roller guide in position with the guide adjusting screw. Do not set the roller guides too close as this will adversely affect the life of the saw blade.

A. 1620 feet/min for hardwoods, some plastics and certain nonfer- rous metals.
B. 3340 feet/min for all other timber.
The lower bandwheel has two, integral,
The drive belt passes around the bandwheel pulley, the motor pulley and the tension wheel. The belt tension is released and applied by using the crank handle (See FIG. 22). This moves the tension wheel and allows the speed to be changed.
(See DRIVE BELT POSITIONS HIGH/LOW SPEED on page 11)
