Komatsu D85EX-18 Operation & Maintenance Manual page 280

TROUBLES AND ACTIONS
• If the engine stops or the oil pressure in the brake circuit
lowers because of a trouble in the hydraulic system, the
brake works and the machine cannot move. To move the
machine in this case, the oil pressure in the brake circuit
must be heightened to the specified level with a special
device. Contact your Komatsu distributor.
• Moving a machine by towing is only used to move it to a
place where it is possible to perform inspection and main-
tenance.
Do not tow it a long distance.
• If it is impossible to operate the steering and brakes of the
machine being towed, do not let anyone ride on the ma-
chine.
• Keep the angle of the towing line to the minimum. Operate
the machine so that the angle does not become greater
than 30 ° from the straight travel direction.
• If the machine gets stuck in the mud or a heavy thing
needs to be towed, install a towing wire rope to the towing
hook as shown in the figure. If the machine is equipped
with a drawbar, install the wire rope to the drawbar pin,
and perform the towing operation.
