Using a straight edge (A) Fig. 6, make certain the motor

pulley (B) is aligned with the arbor pulley. If necessary,

the motor pulley (B) can be adjusted on the motor shaft

by loosening set screw and moving the motor pulley (B)

in or out as needed. The motor (E) can also be moved in

or out along the mounting bars (F) by loosening the four

mounting screws, two of which are shown at (G) and

moving the motor (E).

Assemble the drive belt (H) Fig. 7 to the arbor pulley and

motor pulley (B). Adjust for proper belt tension by raising or

lowering motor (E) on motor mounting posts (J) (one is

shown), by loosening four mounting nuts, two of which are

shown at (K). If necessary, the motor mounting bars (F) can

be repositioned on two mounting posts (J). NOTE: MAKE

CERTAIN BOTH PULLEYS ARE KEPT IN ALIGNMENT

WHEN ADJUSTING BELT TENSION. Correct belt tension

is obtained when there is approximately one inch deflection

in the center span of the belt using light finger pressure.
