Vertical Adjustment
Loosen the two forward bolts (Part #117), securing the
left and right motor supports to the motor support plate
and shift motor and plate up or down slightly until cen-
tered. Retighten bolts securely.
Note:
It is only necessary to loosen these bolts
slightly. In most cases, adjustments can be made by
loosening only the first two bolts closest to the rear
wire guard. If additional adjustment is necessary,
repeat this step by loosening the two rear bolts.
If no vertical adjustment is required, these bolts are
already properly tightened by the manufacturer.

Horizontal Adjustment
Loosen the bolts (Part #56) securing the motor to
the motor support plate and shift motor from side
to side until centered. Tighten bolts securely.
Once the blade assembly is secured to the motor, rotate it by
hand to check for a centered circular rotation.
THERE MUST BE EQUAL SPACE OF APPROXIMATELY 1/4"
BETWEEN THE PINS AND THE END OF THE BLADES.
