The Safety Switch is only used with the Hakko 100L and Hakko 120L air pumps. It is designed to protect the motor and magnet from damage. Under normal operation the diaphragms in your pump will gradually wear out or tear. The magnet is attached to the diaphragms. If the diaphragms fail then the magnet will be out of balance and will vibrate loudly. The safety switch senses the excess vibration and turns off the motor to save wear and tear on other parts. Sometimes during shipping a new pump may have been jarred enough to through out the safety switch. The brand new pump will not turn on right out of the box. Simply remove the top of pump cover and you will see the safety switch at the top of the motor. Notice the small circle with an arrow on it. Just use a coin or flat head screw driver and re-align the arrows. If re-aligning the arrows does not turn on the pump then you may need to purchase a new safety switch. Please check for loose wires. They are relatively simple to replace.

This is the rubber gasket found at the top of the pump just underneath the lid. When you clean the air filters periodically you should also check the integrity of this Top Cover Gasket.

Periodically you will need to replace worn out diaphragms or parts in the Hakko Air Pump. It is easy to do.

Typically your diaphragms should last 1 year to 3 years. This depends on the heat or back pressure in the system. See article Heat Control for Hakko.
