b.Spray directly into spinning fans at full speed
c.Use it while the unit is powered on and open
d.Use short bursts, keep the can upright, and hold fans still to avoid over-spinning

Compressed air should be used in short bursts with the can upright, and fans should be held still so they do not over-spin and get damaged. Powering on the unit or forcing fans to spin can cause damage or injury.
