Telehandlers are machines that are meant to operate in rough terrain, however, that doesn't mean that they can be driven without any regard for the terrain. These equipments have a a lot bigger risk of load loss or tipping over when they are traveling on slopes.
When traveling on a slope, make certain that you move slowly with the equipment while also keeping the load low. Downshift to 4WD and a lower gear, before getting on the slope. Using the engine brake would help to control the telehandler's speed. Try not to turn on a slope if possible. If you need to make the turn, utilize extreme care and take it as wide as possible.
Under any circumstances, avoid driving across extremely steep slopes. Descend and ascend slopes with the telehandler's heavy end pointing up the incline. Even when there is no cargo on the forks, the counterweighted rear of the equipment is quite heavy; therefore, it could be required to drive in reverse up slopes. When the telehandler is carrying a cargo, the front of the unit becomes the heavy end, and you can back the machine down the slopes.
Operator training is extremely important on a mixed jobsite. Rear pivot machinery would usually operate on the same jobsite of coordinated steering machines, where everyone is allowed to operate all of the equipment. In this instance, an individual who is used to operating a coordinated steer machine could jump onto a rear-pivot equipment. A really key difference between how these two units operate depends on which part of the machine extends outside of the turning radius.
