WARNING
Always use the correct towing equipment and towing
method. Any mistake in the selection of the wire rope or
drawbar or the method of towing a disabled machine and
being towed may lead to serious personal injury or death.
• Always confirm that the wire rope or drawbar used for
towing has ample strength for the weight of the ma-
chine being towed.
• Never use a wire rope which has breaks in strands (A),
reduced diameter (B), or kinks (C). There is a danger
that the rope may break during the towing operation.
• Always wear leather gloves when handling the wire
rope.
• Never tow a machine on a slope.
• During the towing operation, never stand between the
towing machine and the machine being towed.
• Operate the machine slowly and be careful not to ap-
ply any sudden load to the wire rope.
• When towing a machine, travel at a speed of less than
1 km/h for a distance of only a few meters to a place
that is suitable for performing repairs.
• This method is applied only in emergencies.
NOTICE
The maximum towing capacity for this machine is 5000 kg.
