have left the area before moving this machine.
2. Slow down the work cycle and use slower travel speeds in congested or
populated areas. Use a commonly understood signal so that others can warn
the operator to slow or halt work in a possible hazardous situation.
3. Strong rains, fog, and extremely dusty and blowing conditions can obscure
visibility in your work area. Wait for weather to improve before continuing
work.
4. Anyone standing near the machine is at risk of being injured. Make certain
they keep away from any moving assembly during working operations.
5. There are standard guards in place on this machine. These are to be
removed only when service or maintenance is being performed in that area.
Reinstall guards after work has been completed.
6. Check and service the fire extinguisher (if so provided) at regular intervals.
Make certain all personnel are trained in its use. Note - Non-use of fire
extinguisher still requires that it be recharged at the interval stated on its last
inspection notice.
7. There are lockups on this machine that are used for both work and travel.
These should be kept clear and free of debris, grease, etc. See Lockup
section for instructions on their use.
8. Inspect safety decals and replace when they become unreadable or are
damaged. (See “Safety Decals” at the end of this Safety section).
9. Keep steps, walkways, and the top of the turntable clear and free of oil, ice,
mud, ballast, tools and other loose objects.
10. When mounting and dismounting the machine, use the handrails and steps
provided. Do not climb onto the machine in any other manner.

1. Always make certain that lockups provided on this machine are free of debris
or grease and are in place prior to travel.
2. Operate the machine carefully when bad weather conditions exist. Maintain a
distance between machines that will allow you room to stop.
3. Strong rains, fog, and extremely dusty and blowing conditions can obscure
visibility in your area. Wait for weather situation to improve before continuing
travel.
4. Anyone standing near the machine is at risk of being injured. Make certain
they keep away from the machine during travel operations.
5. Never change direction of travel without bringing the machine to a complete
stop.
