When driving heavy machinery, whether loaded or unloaded, safety should always be the priority. Here are some general guidelines to consider:

• Speed: Always travel at a low speed [1], especially when operating on ramps or uneven ground [1]. Using the low speed setting helps maintain control [1].
• Ground Conditions: Ensure the ground is level and hard [2]. Remove any slippery materials like mud, dirt, water, snow, ice, grease, or oil to prevent skidding [2].
• Ramps/Platforms: When using ramps, platforms, or embankments, make sure they have sufficient width, length, slope, rigidity, and strength to support the machine [3]. The angle of the ramp to the ground should be 15 degrees or less [4].
• Balance: Be aware that the machine's center of gravity can change abruptly, especially when going over the top of a ramp. Travel slowly to maintain balance [5].
• Auto Acceleration: Turn off the auto acceleration switch to prevent sudden changes in engine speed [5].
• Turning: Avoid turning on ramps to prevent tipping. If a turn is necessary, return to level ground first [3].
• Attachments: Do not use attachments for loading or unloading the machine [1].
• Communication: When loading and unloading, it can be helpful to have a signal person to guide you [2].
• Securing: After loading, lock any safety devices such as guards and doors [6].
• Pre-checks: Investigate the travel route for overpass clearances [7]. Obey all laws that govern the characteristics of a load (height, weight, width, and length) [7].

Remember that operating a machine with a load will change its center of gravity and handling characteristics. Always adjust your driving accordingly and prioritize safety.
