Maintenance Instructions ADJUSTMENTS
Reduction Chain Tension Adjustment
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.
Gauge Wheel Height Adjustment
Debris Blower Drive Belt Tension
The drive belt deflection must be 1/8 in. (3 mm)
when 6-1/2 to 9 lbf (29 to 40 N) is applied midway
between the two pulleys.
Proper Drive Belt Deflection
1. Remove the belt guard from the debris blower
housing by removing the two (2) cover pins and
hairpins securing it to the housing.
2. Loosen the two (2) nuts and bolts on the blower
pulley bearing support and turn the adjustment
nuts on each side until the required tension is
reached. Tighten the fasteners securely and re-
install the belt guard by reversing the removal
procedures.
