Slope Safety

  • Operate the machine up and down slopes with the heavy end of the machine uphill. Weight distribution changes with attachments. This attachment makes the front of machine the heavy end.

  • Keep the attachment in the lowered position when on slopes. Raising the attachment on a slope affects the stability of the machine.

  • Slopes are a major factor related to loss of control and tip-over accidents, which can result in severe injury or death. Operating the machine on any slope or uneven terrain requires extra caution.

  • Establish your own procedures and rules for operating on slopes. These procedures must include surveying the site to determine which slopes are safe for machine operation. Always use common sense and good judgment when performing this survey.

  • Slow down and use extra care on hillsides. Ground conditions can affect the stability of the machine.

  • Avoid starting or stopping on a slope. If the machine loses traction, proceed slowly, straight down the slope.

  • Avoid turning on slopes. If you must turn, turn slowly and keep the heavy end of the machine uphill.

  • Keep all movements on slopes slow and gradual. Do not make sudden changes in speed or direction.

  • If you feel uneasy operating the machine on a slope, do not do it.

  • Watch for holes, ruts, or bumps, as uneven terrain could overturn the machine. Tall grass can hide obstacles.

  • Use caution when operating on wet surfaces. Reduced traction could cause sliding.

  • Evaluate the area to ensure that the ground is stable enough to support the machine.

  • Use caution when operating the machine near the following:

    • Drop-offs

    • Ditches

    • Embankments

    • Bodies of water

    The machine could suddenly roll over if a track goes over the edge or the edge caves in. Maintain a safe distance between the machine and any hazard.

  • Do not remove or add attachments on a slope.

  • Do not park the machine on a hillside or slope.

Stump Grinder Safety
