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.
WARNING: Unplug tool from the power source before troubleshooting.
