Travel and Operation Precautions
Confirm the relative positions of the undercarriage and operator before operating the machine.
Traveling with the machine may present hazards. When traveling with the machine, always travel in a safe,
controlled manner, and remain alert at all times. Be sure the areas around the machine are clearly visible.
When traveling over rough ground, travel at a low speed and steer carefully. Whenever possible, avoid traveling
over obstacles or raised areas. Traveling over obstacles or raised areas could result in loss of control or damage to
the machine. When traveling over raised areas, always travel at a low speed.
During travel, always maintain a safe distance from people and surrounding objects. Always check to make sure
areas such as bridges and roadways will support the weight of the machine before attempting to cross.
Before traveling in public areas, always gain approval from local authorities and follow their instructions.
Raise work equipment 8 in.–12 in. (20 cm–30 cm) above the ground when traveling.
When traveling or operating in shallow water, be aware of its depth and current.
Inclined Areas
Traveling on an incline can be dangerous. To prevent tipping, loss of control, or a rollover, it is important to follow
these rules:
•
Always check the firmness of the inclined surface before attempting to travel on it.
•
Always travel straight up or straight down an incline.
•
Avoid turning on an incline.
•
Avoid sudden stops.
Snow or Frozen Surfaces
Be careful when traveling or operating the machine on frozen or snow-covered surfaces. The ability to maneuver
the machine is seriously affected. The machine may not respond as expected when turning. Other precautions are:
•
Avoid any rapid movement, acceleration, or quick stopping. Always be aware of the increased stopping
distance required on these surfaces.
•
Avoid deep snow or frozen bodies of water.
•
Even a slight incline may cause the machine to slip. Be extra careful when working on an inclined surface
covered with snow or ice.
•
When traveling or moving the machine on a snow-covered incline, allow the machine to come to a stop
slowly.
