shroud to move into the path of the rotat-
ing blades and loose radiator mounting
bolts can allow the radiator to flex in
position, allowing the shroud to come
into contact with the rotating fan blades.
4. Ensure all fan guards have been installed
and firmly secured into place. The
Reversible Fan creates an abundant
amount of airflow in both cooling and
cleaning mode operation. The result of
this airflow is a strong vacuum effect that
can suck in items that are located inside
or around the engine compartment fan.
5. To ensure maximum efficiency, start with
a clean cooling system free of debris,
paying particular attention to the stacked
cooler core(s).
Service and Maintenance
Under normal operating conditions, the
Reversible Fan does not require scheduled
maintenance (other than lubrication) and is
built to provide thousands of hours of
trouble-free service.
In moderate to extreme operating
conditions, a visual inspection of moving
parts is recommended from time to time to
safeguard against fan blade damage, which
could lead to equipment and/or other damage.

the fan. Failure to comply may result in
engine turnover, serious injury, or death.
CAUTION
Never adjust the hydraulic tread width on
a public roadway. Ensure the machine is
on level ground where there are no
ditches or valleys to interfere while you
perform the adjustment.
