Disassembling the Primary Pump Head
5
Check the pump pistons for scratches, grooves and dents
when changing the piston seals.
Damaged pistons cause micro leaks and will decrease
the lifetime of the seals.
6
Use the soft plastic side of the insert tool for removing
the pump seal from the pump chamber housing.
Do not use the pump piston for that purpose!
7
If the wash seal shall be replaced by a new one, use the
steel side of the insert tool for removing it.
