 Maintenance

 

 Hazardous suction. Suction through the PoolShark can entrap bathers, causing 

severe injuries or drowning. Do not operate the PoolShark cleaner while people are using the 

swimming pool. Do not allow anyone to play with the PoolShark or its hoses. 
Your PoolShark can stay in the pool at all times except during chemical shock treatments. 

However, when people are using the pool, disconnect the PoolShark and pull it to one side of 

the pool. 
The PoolShark requires almost no maintenance. Manually open and close the regulator valve 

from time to time to flush away accumulated dirt and debris and ensure smooth operation. 

Also, from time to time, visually inspect the PoolShark to be sure that: 

• The oscillator moves freely and is not obstructed by debris.
• The vacuum pad is not excessively worn. When the traction pads on the bottom have worn 

down, it’s time for replacement. 

Notice:

 When storing the PoolShark, do not coil the hose. Instead, lay it out straight and flat 

in an area protected from direct sunlight. Use only a genuine PoolShark hose. The warranty is 

void if the cleaner is operated with other than a genuine PoolShark hose.

Troubleshooting

Common Causes of Cleaner Problems:

•  Dirty filter

 

Clean the filter   

 

      

•  Dirty basket in pump hair and lint strainer

 

Clean the basket

•  Debris blocking the bottom of the PoolShark

 

Remove the Debris

•  Leaks in the hose 

 

Remove the leaky section

•  Debris in the regulator valve

 

Clean the regulator valve

•  Low vacuum through the cleaner

 

Close the main drain

Poolshark Doesn’t Move Or Pulsates Slowly:

•  Make sure that the main drain and all other suction lines are closed except the suction line 

to which the PoolShark is attached.

•  Check for debris in the filter or the pump strainer basket.
•  Check for debris in the PoolShark’s oscillator. Debris may prevent oscillator movement or 

restrict the flow through the cleaner.

•  Check the oscillator for: damage; lost seals (there should be 4 seals): obstructed seals 

(seals should slide freely on the oscillator).

•  Be sure that the short, soft leader hose section is the first section in the hose assembly 

(next to the cleaner).
