place the straightedge squarely against the
engine/motor pulley. Remove the straightedge and
rotate the engine/motor pulley 120 degrees.
Recheck alignment with the straightedge. Repeat
the process until the engine/motor pulley is rotated a
full 360 degrees. Maximum allowable misalignment
is + - 1/32 inch. If pulley alignment is not within
specifications, refer to INSTALLING A
REPLACEMENT V-BELT for specific information.

closed before uncoupling the hose. Secure in a
proper storage area. Using the 9/16 inch wrenches,
remove the belt guard from the main frame. Clean
the inside of the belt guard with an appropriate
