OPERATION
TROUBLESHOOTING
When towing a machine downhill, use two towing machines. Use one of these machines on the uphill side and
connect the towing wire or towing bar to apply tension to the towed machine from the uphill side. Use the other
machine to tow from the downhill side.
WHEN ENGINE RUNS
If the transmission and steering wheel can be operated, and the engine is running, it is possible to tow the
machine out of mud or to move it for a short distance to the edge of the road.
Check the effect of the brakes, and if the brakes do not work properly, take the action given in "When engine does
not run".
Check if it is possible to steer the machine. If the machine cannot be steered, follow the procedure given in
"WHEN ENGINE DOES NOT RUN".
The operator should sit on the machine being towed and operate the steering in the direction that the machine
is towed.
Always run the engine to allow the steering and brakes to be used.
WHEN ENGINE DOES NOT RUN
The brakes will not work, so be extremely careful.
Connect the towing machine securely to the towed machine. Use two towing machines of the same class or
larger than the machine being towed: connect one machine each to the front and rear of the machine being towed.
If it is necessary to change the direction of the machine being towed, it is possible to use the emergency steering,
but it can be used for a maximum of only 90 seconds.
If the emergency steering cannot be used, disconnect two hydraulic hoses each on the left and right from the
steering cylinders, then carry out the towing operation. When removing the hoses, block the hoses with plugs and
fit oil containers to the mouthpiece of the cylinder to prevent oil from draining to the ground.
WHEN PARKING BRAKE HAS BEEN ACTUATED IN EMERGENCY
If the pressure in the hydraulic circuit has dropped abnormally because of leakage of oil, the parking brake will be
applied automatically.
If it is necessary to release the parking brake in order to tow the machine, please ask your Komatsu distributor to
carry out the operation.
WHEN FINAL DRIVE, DIFFERENTIAL, TRANSMISSION, TRANSFER HAVE BROKEN DOWN
If necessary, remove the drive shaft or torque shaft before carrying out the towing operation.
