Fault Codes
Before Troubleshooting:
Read, understand and obey the safety rules and
operating instructions in the appropriate
operator's manual on your machine before
attempting any maintenance or repair procedure.
Be sure that all necessary tools and test
equipment are available and ready for use.
Be aware of the following hazards and follow
generally accepted safe workshop practices.
Crushing hazard. When testing
or replacing any hydraulic
component, always support
the structure and secure it
from movement.
Electrocution/burn hazard. Contact
with electrically charged circuits
could result in death or serious
injury. Remove all rings, watches
and other jewelry.
Bodily injury hazard. Spraying
hydraulic oil can penetrate and
burn skin. Loosen hydraulic
connections very slowly to allow
the oil pressure to dissipate
gradually. Do not allow oil to
squirt or spray.
Note: Two persons will be required to safely
perform some troubleshooting procedures.
