While adjusting the air horn it’s recommended that you wear ear protection, 

 

 

to prevent damage to your ears.

 

Although the air horn is tested and adjusted before delivering, it is possible that its setting is 

changed. Altering its setting is possible by loosen or tighten the lid of the diaphragm casing. Be 

aware that if you tighten the lid to far on the diaphragm casing, the diaphragm plate in the lid will 

be damaged.

8. ADJUSTING THE AIR HORN

9. MAINTENANCE

The Single-tone set is almost maintenance free.  Make sure the air horn is clean and give the com-

pressor two drops of hydraulic oil monthly. Don't paint the air horn, because this can reduce the 

sound pressure level and alter its frequency.
