A high pressure blower requires a certain amount of resistance which will prevent motor over
amperage.
Make sure power source matches wire voltage configurations.
Check set screw and key in fan wheel, make sure fan wheel is secure, fan blower should not
vibrate.
REMINDER: Check Motor and Fan Lubrication Schedule.
