Towing

WARNING

When towing, selecting the wrong wire

rope, inspecting improperly, or towing in

the wrong way could lead to accidents

resulting in serious injury or death.

¡The wire rope breaking or coming

detached could be extremely

dangerous. Use a wire rope suited for

the required towing force.

¡ Do not use a wire rope that is kinked,

twisted or otherwise damaged.

¡ Do not apply strong loads abruptly to

the wire rope.

¡ Use safety gloves when handling the

wire rope.

¡ Make sure there is an operator on the

machine being towed as well as on the

machine that is towing.

¡ Never tow on slopes.

¡ Do not let anyone near the wire rope

while towing.

Towing the Machine

Use the procedure described below to tow

heavy objects or the machine itself if it should

get stuck in the mud and not be able to get

out on its own.

N0A006

1. Fasten the wire rope to the frame.

2. Place splints or other objects between the

wire rope and frame to prevent the

machine and wire rope from getting

damaged.

3. Move the machine to tauten the wire rope.

4. Move the machine slowly and tow.
