SAFETY PRECAUTIONS 

 

1.  Do not operate blower with open inlet or outlet port. 

 

2.  Do not exceed specified vacuum or pressure limitations. 

 

3.  Do not operate above or below recommended blower speed range.   

 

4.  Blower is not to be used where non-sparking equipment is specified. 

 

5.  Do not operate without belt guard or coupling shield. 

 

 

Do not exceed sheave or coupling manufacturer’s rim speed limit. 

 

6.  The blower and blower discharge piping may be extremely hot and cause skin burns on contact. 

 

7.  Prolonged exposure may require ear   protection. 

 

TROUBLE SHOOTING 

 

No matter how well the equipment is designed and manufactured, there may be times when servicing will be 
required due to normal wear, the need for adjustment, or various external causes.  Whenever equipment needs 
attention, the operator or repairman should be able to locate the cause and correct the trouble quickly.  The 
Trouble Shooting Chart below is provided to assist the mechanic in those respects.
