for all moving parts to stop, and remove key. Place rollers in one of the
positions shown in Figure 12. Rollers will maintain 3/4 in. (19 mm)
clearance to the ground to minimize gouging and roller wear or damage.
For Maximum Deck Flotation, place rollers one hole position lower.
Rollers should maintain 1/4 in. (6.4 mm) minimum clearance to ground. Do
Not adjust rollers to support the deck. Be sure bolt is tightened properly or
loss of anti-scalp roller may result.
