OPERATION

Initial Start Up

Preliminary Checks

Before operating a blower that has been stored for any length of time, 

remove the intake and exhaust covers and inspect the rotors and cylinders to 

insure the absence of rust.  In addition, remove the oil fill plug on the drive 

oil tank and inspect the gear for absence of rust. 

Verify the blower spins freely by hand.

Verify all connections between the plumbing system and the blower flanges 

are in place and tight.

Verify oil levels through sight eyes.  If additional oil is required, see the  

maintenance section for details.

Verify the blower is set-up to spin the correct direction, especially when  

using a gearbox.

Verify all guards are in place.

·

Insure personnel wear hearing protection as noise levels can 

exceed 85 dB.

·

Do not rotate the blower in the reverse direction for more than a 

few revolutions

Starting the blower

HOT Shift PTO’s - Do not engage “Hot Shift PTO’s” outside of manufacturers 

specifications as damage to the PTO, driveline or blower may occur.  Slowly 

ramp the blower up to speed to prevent shocking the system.  

Increase the vacuum level slowly until the rated level is reached. During the 

first 8 hours of operation, check that there are no vacuum leaks, oil leaks, 

vibrations or strange noises.
