Debris Blower Front Gauge Wheel

Adjust the gauge wheel height according to surface condition.

IMPORTANT: The air blast nozzle must clear the ground at all times.

1.Remove the linchpin from the wheel pivot shaft.

2.Adjust wheel height by placing sleeve spacers either on the upper or lower side of the wheel pivot bushing. Placing the spacers on the low- er side increases gauge wheel height. Placing the spacers on the upper side lowers gauge wheel height.

3.Reinstall the linchpin when proper gauge wheel height has been reached.
