TROUBLE SHOOTING

Where to set Sensor Bar

" Increments)

Machine turns or hesitates on pool drain:
  Raise sensor bar slightly to clear drain.

Machine fails to come out of deep end:
  Raise sensor bar to allow machine to climb on incline.

Machine turns away from curved wall too soon:
  Raise sensor bar to allow machine to clean higher on curved portion, but still turn 

away before tipping over. 

Machine tips over before tripping or sensing wall:
  Lower sensor bar until it trips. However, a slight adjustment might have to be 

made by clipping one or two coils off the spring #2207L (Page 9, Key 25) that is 
located directly behind sensor bar slide #1707 (Page 9, Key 21).  

Machine turns in circles and twists cord:

1. Sensor bar too high, hitting hood. 

2. Thread on reversing arm #1703 (Page 9, Key 64) is worn or stripped, not 

allowing reversing mechanism to disengage. 

3. Sensor bar cable screws are loose. 

4. Drive wheel broken. 

5. Drive belt broken. 

6. Because of various pool designs, especially those with a gradual slope up the 

sides, the unit has a tendency to attempt to make the climb. To prevent the 
machine from turning over, a sensor bar weight* can be attached to both sides. 
This is  automatically activated when the machine has reached a maximum 
point of ascension, reversing the unit. Remember the basic rule: KEEP THE 
SENSOR BAR LOW AND LEVEL. 

7. Sensor Bar must always be level to avoid cord twisting!

8. Is the unit being run in the pool for too great a length of time? 150 minutes of 

operation in a 30' x 60' pool should be sufficient with not more than a few twists 
in the cord set, which should be straightened out after each vacuuming.

 * Must be ordered from factory.
