TROUBLESHOOTING
6-15
After towing another machine loosen the counter-nut (4) and the
threaded stud (5) by turning it anti-clockwise until it reaches the
limit stop. Hold the valve (3) in position using a wrench an re-
tighten firmly the counter-nut (4). Perform these operations on
both valves.

• When the engine is switched off, the power-assisted
steering is not operational, i.e. you have to apply much
more force to steer the machine.
If you lift up the rear axle of the machine with a lorry-mounted
crane, you can tow off the machine over longer distances and at
speeds exceeding 1.2 mph (2 km/h). Before you do this you
must, however, remove the cardan shaft of the front axle. In ad-
dition, secure the articulated steering with the locking bar, in the
same way as it is required for transport of the machine on a low
bed loader or by train.
TOWING A MACHINE WITH DEFECTIVE BRAKES
• If the brakes of the machine that you want to give a tow
are defective, uncontrolled movement of the machine may
cause a crash while it is being towed!
Always use two machines to tow off a machine with defec-
tive brakes. Connect all three machines with appropriate
towing attachments.
If you want to tow a machine a with defective brakes, or if you
have to tow a machine driving downhill, use two machines for
towing. Attach the machine that you want to give a tow to a larg-
er machine with sufficient tractive and braking force. Attach a
second machine to the rear part of the machine that you want to
give a tow. In this way, you avoid uncontrolled movement of the
machine.
Towing can be performed under various conditions. Thus, it is
impossible to determine all the requirements that may apply to a
particular condition. When towing on an even and horizontal sur-
face, the tractive force that you need is much less than the trac-
tive force that you need when towing on a slope or uneven
surface.
Please ask your local Komatsu dealer for details, if you want to
give a particular machine a tow.
