6.3 Towing the Machine

Towing the machine improperly or using
wire cables beyond the speci

cation could

lead to serious injury or death.

●

Make sure that the wire cables used for
towing the machine are strong enough,
which may otherwise result in acci-
dents.

●

While towing the machine, do not use
wire cables with broken wires (A), re-
duced diameter (B) or knot (C) in order
to prevent rupture of the wire cables.

●

Always wear protective gloves when
handling wire cables.

●

Never tow the machine on a slope.

●

Never stand between the towing ma-
chine and the towed machine when
performing towing operation.

●

Operate the machine slowly and avoid
imposing sudden load on wire cable.

Note:

The towing operation must be performed with-
in the maximum towing capacity.
