Telehandlers are machines that are designed to operate in rough terrain, although, that doesn't mean that they could be driven without any regard for the environment. These equipments have a much greater risk of load loss or tipping over when they are traveling on slopes.
When traveling on a slope, make sure 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 will really help to control the telehandler's speed. Try not to turn on a slope if possible. If you must make the turn, utilize extreme care and take it as wide as possible.
Under any circumstances, do not drive across very steep slopes. Ascend and descend slopes with the heavy end of the telehandler pointing up the incline. Even when the forks have no cargo, the counterweighted rear of the machinery is fairly heavy; hence, it could be required to drive backwards up slopes. When the telehandler is carrying a load, the front of the unit becomes the heavy end, and you can back the machinery down the slopes.
Operator training is hugely vital on a mixed jobsite. Rear pivot machines would often operate on the same jobsite of coordinated steering machinery, where everybody is permitted to use all of the equipment. In this case, a person who is used to utilizing a coordinated steer machinery can jump onto a rear-pivot machinery. A very significant distinction between how these two units operate has a lot to do with what part of the machinery extends outside of the turning radius.
