Fan Operation
Fan Safety Information
Rotating Fan Blade Hazard:
Do not operate the fan with guard screen removed. The fan
accelerates instantly and with high torque. Body parts and
clothing can be drawn into fan, resulting in death or serious
injury. Disconnect fan circuit at hitch when working on fan.
High Pressure Fluid Hazard, Fan Hydraulic Motor:
Escaping fluid under pressure can have sufficient pressure to
penetrate the skin causing serious injury. Use a piece of paper
or cardboard, NOT BODY PARTS, to check for leaks. Wear
protective gloves and safety glasses or goggles when working
with hydraulic systems. If an accident occurs, seek immediate
medical assistance from a physician familiar with this type of
injury.
Sudden Auger or Fan Movement:
Set FAN/AUGER selector valve (if present) to FAN before
activating tractor hydraulic remote for fan hydraulic circuit. If
the fan does not start when slowly moving circuit lever, set
lever to Float or Neutral and check selector valve.
Machine Damage Risk:
Protect motor seals: Fan circuit has three hoses. All must be
correctly connected. Make sure that “SUMP” line is
connected to tractor case drain.
Avoid sudden circuit changes. Motor seals may be damaged by
rapid starts and stops, or by circuit reversals. Engage fan
circuit lever slowly, while observing fan rpm on seed monitor.
Note: Avoid fan direction reversal. A fan running in
reverse cannot generate sufficient airflow for
planting. If fan cannot reach target rpm, check for
reversed circuit connections or improper drain
connection. The fan is running in reverse, the auger
material movement direction is also reversed
(relative to the decal illustrations).
