shut off engine and remove key from ignition

2. Raise seat or remove left side panel from rider.
3. Place height-of-cut lever in number 3 position
and position cutter blade at a right angle to
direction of rider travel.
4. Measure the blade tip height at one end of blade,
rotate blade 180 degrees and measure same blade
tip at opposite side of rider. Measurement should
be within 1/8 inch (3 mm) of one another.
