Preservation
Keep all intake, exhaust and ballast port coverings in place to prevent debris
or liquids from entering blower. Reapply rust preventative oil to all metal
parts, including the compression chamber every 6 months or more frequent-
ly if the relative humidity is greater than 80%.
While in storage, rotate the shaft three to four revolutions every two weeks
to keep gears coated in oil.
Before installing 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 drive oil tank and
inspect the gear for absence of rust.

INSTALLATION
Rotation and Airflow
Diesel Engine Precautions
·
DO NOT OPERATE BLOWER WITH A DIESEL ENGINE RUNNING
AT LOW RPM’S AS TORQUE PULSES CAN CAUSE ROTOR LOBE
CONTACT AND DAMAGE TO THE BLOWER.
When directly driving the blower with Diesel engine, bring the engine up to
operating RPM and then engage the blower via the clutch. Be sure to start
the blower under no load conditions.
Use caution when using a Diesel engine that is significantly oversized for the
operating point of the blower. Doing so can result in an inertial mismatch,
excess torsional vibrations at low RPM’s and blower lobe contact.
For more information Diesel torsional vibrations, see the technical report by
LoveJoy titled New Twists to Diesel Vibration at
