Contact your local Komatsu dealer to obtain detailed information on
towing.
Observe the following instructions if the machine has to be towed with
the engine switched off:
•
Set either the driving direction lever or the driving direction switch to
the neutral position.
•
A towing speed of 10 kph and a towing distance of 10 km must not be
exceeded if damage to the power-shift transmission, due to insufficient
lubrication, is to be avoided when towing with the engine switched off.
•
Steering is only active during drive because the emergency steering
pump is driven by the axles via the cardan shafts of the power-shift
transmission.
•
The pressure reserve for the service brake is used up completely
after only a few braking actions. After this, only the parking brake can
be used for braking.
The articulated steering must be locked in place when the machine is
transported on a low-bed truck, by rail or towed by a mobile crane.
The cardan shaft of the running axle has to be removed when the front
axle is to be raised. The parking brake does not work if the cardan shafts
have been removed.
WARNING
If the machine to be towed has defective brakes, it may collide
during the towing!
Use two machines to tow a machine with defective brakes.
Connect the three machines with tow-rods.
If you need to tow a machine with defective brakes or if the machine is
being towed downhill, use a larger machine for towing to ensure that
there is sufficient tensile force and braking performance. Connect a se-
cond machine to the rear of the machine to be towed. This helps to
prevent the machine getting out of control.
Conditions for towing can vary, so that it is impossible to predict basic
requirements in advance. Towing on level and horizontal roads requires
only little tensile force; towing on slopes or uneven ground requires a
high tensile force.
