Safety Practices
8. Tip Over Hazard
Traveling with the boom raised is dangerous and can cause tipover. Keep the
boom as low as possible. Travel with extreme caution and at the slowest
possible speed.
Keep the vehicle under control at all times. When negotiating turns, slow down
and turn the steering wheel in a smooth sweeping motion. Avoid jerky turns,
starts or stops. Reduce vehicle speed on rough ground and slopes.
DO NOT exceed the rated lift capacity of the vehicle as structural damage and
unstable conditions will result.
To ensure that the vehicle is positioned in the most stable condition before
operating an attachment, use the frame sway control (frame tilt) to level the
vehicle. The vehicle is level when the frame level indicator gauge reaches (0 )
zero degrees.
If the vehicle cannot be leveled using the frame sway control, reposition the
vehicle.
Frame swaying left or right with the boom raised above horizontal is dangerous.
Always use the frame sway control to level the vehicle before raising the boom
above horizontal, with or without a load. If the vehicle cannot be leveled using
the frame sway control, reposition the vehicle.
