Maintenance

Your PiranhaMAX is designed to provide years of trouble-free operation with
virtually no maintenance. Follow these simple procedures to ensure your
PiranhaMAX continues to deliver top performance.
Control Head Maintenance
It is important to consider the following precautions when using your PiranhaMAX.
WARNING! Do not use a chemical glass cleaner on the screen. Chemicals in the
solution may cause cracking in the lens of the unit.
• Chemicals, such as those found in bug spray and sunscreen, may cause
permanent damage to the control head screen. Such damage is not
covered by the warranty.
• Never leave the unit in a closed car or trunk—the extremely high
temperatures generated in hot weather can damage the electronics.
Use the following information to keep the control head and screen clean.
• Screen: When cleaning the LCD protective screen, use a chamois and
non-abrasive, mild cleaner. Be careful to avoid scratching the lens.
NOTE: Do not wipe the screen while dirt or grease is on the screen.
• Control Head: If the unit comes into contact with salt spray, wipe the
affected surfaces with a cloth dampened in fresh water.
Transducer Maintenance
Use the following information to maintain the transducer operation.
• If your boat remains in the water for long periods of time, algae and other
marine growth can reduce the effectiveness of the transducer. Periodically
clean the face of the transducer with a mild, marine-safe and plastic-safe
soap or solution.
NOTE: To clean the transducer, you may need to pivot the transducer up in the bracket.
• If your boat remains out of the water for a long period of time, it may take
some time to wet the transducer when returned to the water. Small air
bubbles can cling to the surface of the transducer and interfere with proper
operation. These bubbles dissipate with time, or you can wipe the face of
the transducer with your fingers after the transducer is in the water.
