Drive Shaft
U-Joint operang angles at each end of the sha should always be at least 1° to
prevent yoke bearing failure, but do not exceed the manufacturers maximum
recommended angles for the operang RPM.
U-Joint operang angles on each end of a drivesha should always be equal within
1° of each other to cancel an angle vibraon.

· Use a drive sha loop to catch sha in the event of failure.
· It is suggested that overload protecon be used on the blower driveline.
Hydraulic Drive
The blower can be driven with an appropriately sized hydraulic system ulizing a
hydraulic motor with an SAE B or C, 4-bolt or 2-bolt ange by purchasing a hydrau-
lic mount (purchased separately) and appropriate couplers.
PTO Drive
PTO’s must be properly sized to drive the blower. For more informaon on driving
blowers with PTO’s, please see the Chelsea Blower Torque Guide Bullen HY25-
0075-B1-US available at www.parker.com .
· Improper use of “Hot Shi” (i.e. clutch type, constant mesh) PTO’s can
result in severe damage to the blower driveline and blower. Take extra
precauons to operate PTO’s within the manufacturer’s recommendaons
Plumbing and Piping
Do not hang plumbing from blower anges. Use isolang anges or isolang hose
to couple blower to piping to prevent dead weight from hanging o blower and
to allow for thermal expansion. Failure to do so may result in rotor contact with
housing. Use only clean piping insuring it is free of dirt, scale, cungs, weld spat-
ter, and foreign materials of any kind.
