5.  Turn the bottom nuts to tension the belt(s) 

while holding the top nuts. This action 

moves the indicator upward. Continue 

tightening the bottom nuts until the indicator 

pin is again at the top of the indicator slot.

6.  Replace/close and latch the front panel/

doors. Lower the top panel and latch.

7.  Unlock the power and start your  Qube.

8.  Resume normal operation.

6.4  PREVENTATIVE MAINTENANCE

A good maintenance program will add years of 

service to your blower.  A newly installed blower 

should  be  checked  frequently  during  the  first 

month of operation, especially lubrication. Check 

oil level in both the drive end and gear end of 

the blower and add oil as needed. Complete 

oil changes are recommended every 1000 

operating hours, or more frequently depending 

on the type of oil and oil operating temperature.  

The following is recommended as a minimum 

maintenance program.

DAILY

WEEKLY

MONTHLY

1.  Check and maintain oil level, 

and add oil as necessary.
2.  Check for unusual noise or 

vibration (See 

Troubleshooting

)

1.  Clean all air filters. A 

clogged air filter can seriously 

affect the efficiency of the 

blower and cause overheating 

and oil increased oil usage.  

Replace if necessary.

1.  Inspect the entire system for leaks.
2.  Inspect condition of oil and change if necessary.
3.  Check drive belt tension and tighten if 

necessary.
4.  Inspect check valve.

6.5  LONG TERM STORAGE

Any time the blower will be stored for an extended period of time, you should take make sure that it is 

protected from corrosion by following these steps:

1.  Spray the interior (lobes, housing and end plates) with rust preventative.  This should be repeated as 

conditions dictate and at least on a yearly basis.

2.  Fill both end covers completely full of oil.

3.  Firmly attach a very prominent tag stating that the end covers are full of oil and must be drained and 

refilled to proper levels prior to startup.

4.  Apply a rust preventative grease to the drive shaft.

5. 

Spray all exposed surfaces, including the inlet and discharge flanges, with rust preventative.

6.  Seal inlet, discharge and vent openings.  It is not recommended that the unit be set in place, piped to 

the system, and allowed to remain idle for a prolonged amount of time.  If any component is left open 

to the atmosphere, the rust preventative will escape and lose its effectiveness.

7.  During storage, ensure that the blower does not experience excessive vibration.

8.  Attach a desiccant bag to either of the covers to prevent condensation from occurring inside the blower.  

Make sure any desiccant bag (or bags) is so attached to the covers that they will be removed before 

startup of the blower.

9.  Store the blower in an air conditioned and heated building if at all possible.  At least insure as dry 

conditions as possible.

10. If possible, rotate the drive shaft by hand at least monthly in order to prevent seals from setting in one 

position.
