TUBEAXIAL-M

Start Up

Restore power to the fan, turn it on and check for the following.

• Correct rotation

• Improper amperage

• Excess vibration

• Unusual noise

• Incorrect belt tension or alignment

If a problem is discovered shut off the fan and refer to the section on troubleshooting to

discover the cause of the problem. The fan should be inspected after 30 minutes, 8 hours and 24

hours of operation to ensure all fasteners are tight and belts are properly tensioned and aligned.

MAINTENANCE

WARNING

________________________________________________________________________

Disconnect and secure to the OFF position all electrical power to the fan prior to inspection or

servicing. Failure to comply with this safety precaution could result in serious injury or death.

1. Fans should be checked at least once a year. For critical or severe applications, a routine

check every two or three months is suggested.

2. When removing or installing a belt, do not force the belt over the sheave; loosen the

motor mount so that the belt can be easily slipped over the sheave.

3. The belt on belt driven units should be removed and carefully checked for cracks, ply

separation and irregular wear. A small irregularity in the contact surface of the belt will

result in noisy operation. If any of these defects are apparent, the belt should be replaced.

At the same time, check the sheaves for chips, dents or rough surfaces that could damage

the belt.

4. The correct belt tension is important. Too tight a belt will result in excess bearing

pressure, which can cause premature bearing failure and may cause the motor to

overload; too loose a belt will result in slippage, which will burn out belts. Proper belt

deflection should be 1/64” (half way between sheave centers) for each inch of belt span

when a force of approximately five lbs. is applied.

5. The belt alignment should be checked to be sure that the belt is running perpendicular to

the rotating shaft. The motor and drive shafts must be parallel.

6. A periodic inspection of all fasteners should be carried out to ensure they have not

loosened due to vibration. Particular attention should be paid to fasteners

attaching the wheel to the shaft and those attaching the shaft to the bearings.
