Exhaust Retarder

On the trip back to base I notice that the exhaust retarder was not working. It has a switch pedal at the front and an air controlled ram at the back mounted on the exhaust. I clean and checked the ram and it is working fine. Now it is just a matter of checking the front pedal switch and it should work again…

All cleaned and ready to work again. The cloth is a fire and heat resistant material to protect the air hose.
