NOTE: The internal components of the pump and piston area have very close tolerances and are
sensitive to damage from dust, dirt, contamination of the hydraulic fluid or improper handling. The
disassembly of the pump housing requires special tools and training, and should only be attempted by
qualified repair personnel that have been properly trained and have the right tools. The improper
servicing of electrical components can lead to conditions that could cause serious injury. The pump,
piston components and all electrical parts should be serviced only by authorized repair shop, dealer or
distributor.
