ALIGNING PULLEYS,

ASSEMBLING BELT AND

ADJUSTING BELT TENSION

DISCONNECT MACHINE FROM POWER SOURCE

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 (C) 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.

IMPORTANT: BE CERTAIN TO TIGHTEN ALL

MOUNTING HARDWARE ONCE FINAL ADJUSTMENTS

ARE MADE.

ASSEMBLING BELT GUARD

Assemble the belt guard (A) to the stand, as shown in

Fig. 8. Align the holes in the belt guard with the holes on

the machine. Place 1/4" flat washer on a 1/4-20-1/2"

round head screw, insert screw through hole in belt

guard and hole in machine. Thread a 1/4-20 hex nut onto

screw and tighten securely. Repeat this process for the

remaining hole.
