MAINTENANCE AND INSPECTION

Opening the STP pump to the atmosphere may cause a chemical reaction in the deposit. Therefore,

seal the inlet port, outlet port, and purge port so as to prevent the deposit from being exposed to the

atmosphere as much as possible.

For the transport method, see Section 8.5, "Transporting for repair or overhaul".
