Troubleshooting
This section is designed to help trace, solve and prevent some of the more commonly found
problems that may occur in the operation of the coring truck. A good rule of thumb is to look,
listen, smell and feel. Using these four senses will help to identify most problems before they
become major, thus saving down time and avoiding costly repairs.
LOOK: Keeping an eye open for hoses or components that may be worn or leaking is one way of
stopping a problem before it occurs. Be aware of any hazards in and around the work area that
may be a threat to worker safety or the safe operation of the the equipment
LISTEN: Abnormal noises such as squealing or grinding sounds will generally indicate a
problem. Acute hearing will help pinpoint the source of the problem.
SMELL: The smell of most lubricants such as antifreeze and oils can be picked up while doing a
walk around the truck during operation. This may lead to the discovery of such things as oil leaks
or overheating of parts.
FEEL: The sense of feel usually applies when doing an inspection after the unit has been
working for sometime. In warmer climates it is good practice to feel certain hydraulic
components or tanks for excessive heat. If there is a problem of oil overheating it may be detected
by checking hydraulic pumps for heat build up during early hours of operation. Some components
will build up heat quicker if operating incorrectly. Control valves and relief valves may also cause
heat build-up if they are bypassing when not required to do so.
Important: Caution must be taken when inspecting, or touching, any portion of the equipment that
maybe excessively hot to the touch.
Important: Refer to the owner’s manual of the power souece to which your MC450 is attached to.
