ROUBLESHOOTING
This section provides some basic steps to identify possible causes of trouble, together with troubleshooting
solutions. If you cannot solve your maintenance or operation problem with the information provided in this section,
contact the nearest FTI representative.
Failure to observe and comply with the following precautions could result in death or serious
personal injury. Property damage could also occur.
Never tighten or loosen hydraulic fitting while the pump hydraulic system or connected
components are pressurized. Escaping oil under pressure can penetrate the skin, causing serious
personal injury.
Keep hands, finder, and other body parts clear of pinch points and move parts when observing
operation during troubleshooting.
To prevent accidental start-up of pump servicing, always remove battery from pump before
performing any maintenance or repair procedures.
