TROUBLESHOOTING
INTRODUCTION
This troubleshooting section is designed for qualified service
technicians familiar with the operation and repair of electrical
and hydraulic equipment. It is not possible to predict all
problems that might occur or the correct procedure for
troubleshooting each problem. If a problem is encountered
that is not covered in this manual, first consult your
Manitowoc dealer. The Manitowoc Crane Care Lattice
Team can provide assistance, if necessary.
SAFETY SUMMARY
Hazards are always a possibility when performing trouble-
shooting operations on heavy equipment. To minimize the
risk of potential hazards and to prevent serious injury or
death, comply with the following:
• Read the Operator Manual and Service Manual before
beginning troubleshooting operations.
• A qualified service technician-competent in the repair
and testing of electrical and hydraulic equipment-must
complete troubleshooting. Manitowoc is not responsible
for training personnel who might use this manual to
perform troubleshooting operations.
• When possible, turn off the crane engine for safety. Keep
unauthorized personnel away from the crane when
troubleshooting.
• Never troubleshoot the crane alone. Always perform
troubleshooting procedures with a qualified operator in
the crane cab. Maintain constant communication with
this operator when performing operations that require
the crane engine to be running.
• Do not return the crane to service after completion of
maintenance or repair procedures until all guards and
covers are re-installed, trapped air is bled from hydraulic
systems, safety devices are enabled and all
maintenance equipment is removed.
• Perform a function check to ensure correct operation at
the completion of maintenance or repair operations.
The following warnings apply to all troubleshooting
operations. Manitowoc cannot foresee all hazards that may
occur.
You must be familiar with the equipment and trained in the
testing method and use common sense while
troubleshooting to avoid other hazards.
GUIDELINES
The following guidelines apply to all troubleshooting
operations:
• Do not remove cylinders or counterbalance valve(s)
from a cylinder until the cylinder’s working unit is
restrained against movement.
• Do not use your hands to check for hydraulic oil leaks.
Use a piece of cardboard to check for hydraulic oil leaks.
• Use gauges with the correct pressure range when
checking hydraulic circuits.
• Check pressures at the specified hydraulic component
ports.
• Use the
RCL display and main display for checking the
pump, motor, handle, brake, and other components.
• Use the in-line test boards (available from Manitowoc
Crane Care) for further testing of computer nodes and
electrical circuits.
WARNING
Eye, Skin, and Respiratory Hazards!
Wear proper eye and skin protection and avoid direct
contact with battery acid, oil, or ether spray when
searching for leaks, opening connections, or installing
pressure gauges.
Pressurized hydraulic oil can cause serious injury. Turn off
the engine, remove the key, and relieve pressure in the
system before disconnecting, adjusting, or repairing any
component.
Ensure that connections are made correctly, o-rings or
gaskets are in place, and connectors are properly
installed before pressurizing the system.
Use the necessary precautions to prevent electrical burns
when checking battery charging and starter circuits.
Death or serious injury can occur if these warnings are
ignored.
Unexpected Moving Part Hazard!
Keep personnel away from the crane while manually
actuating a valve or pump to avoid unexpected equipment
movement that can cause death or serious injury.
