TROUBLE SHOOTING
WARNING:
• Remove battery before working on machine.
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.
