Refer to the chart below for the maximum allowable return and supply duct lengths
for your machine.
NOTICE: Do not exceed the maximum total lengths specified in the chart.
Exceeding these lengths, or blocking any of the duct openings, constricts the air
flow through the machine and may cause a high-temperature shut-down fault.
Note: Return ducting information is based on typical work applications. Contact
your Wacker Neuson dealer for more information on return ducting configurations.
