Start the engine and raise the cutting unit so the height-of-cut
can be changed. Stop the engine after the cutting unit is raised.
FRONT CASTOR WHEELS
1.
Remove the tensioning cap from the spindle shaft and slide the
spindle out of front castor arm. Remove the washer from the
spindle shaft. Slide spacers onto the spindle shaft to get the
desired height-of-cut, then slide the washer onto shaft.
2.
Push the castor spindle through front castor arm, install the
other thrust washer and remaining spacers onto the spindle and
install the tensioning cap to secure the assembly .
REAR CASTOR WHEELS
1.
Remove the tensioning cap from the spindle shaft.
Note: The rear castor fork assembly doesn’t need to be
removed from the castor arm to change the height of cut.
2.
Remove or add ”C” shaped spacers at the narrow portion of the
spindle shaft, below the castor arm to get the desired height of
cut. Make sure the thrust the washers—not the spacers—con-
tact the top and bottom of the castor arm.
3.
Install the tensioning cap to secure the assembly .
4.
Assure all four castor wheels are set at the same height of cut.
