Telehandlers are machines that are meant to work in rough environment, however, that doesn't mean that they could be driven without any consideration for the terrain. These kinds of machines have a a lot bigger risk of load loss or tipping over when they are traveling on slopes.
If you do have to travel on a slope, ensure that you proceed slowly and carefully while keeping the load low. Before getting on the slope, downshift to 4WD and a lower gear. Utilizing the engine brake would really help to control the speed of the telehandlers. Try to avoid turning on a slope if possible. If you must make the turn, use extreme caution and take it as wide as possible.
Always try to avoid driving across very steep slopes. Use the telehandler's heavy end pointing up the incline, when ascending and descending slopes. Even when the forks have no cargo, the counterweighted rear of the machine is quite heavy; hence, it can be necessary to drive backwards up slopes. Once the telehandler is carrying a cargo, the front of the unit becomes the heavy end, and you can back the equipment down the slopes.
Operator training is extremely essential on a mixed jobsite. Rear pivot machines would usually operate on the same jobsite of coordinated steering machinery, where everybody is allowed to utilize all of the machines. In this case, an individual who is used to using a coordinated steer machinery can jump onto a rear-pivot machine. A really significant difference between how these two units work has a lot to do with what part of the equipment extends outside of the turning radius.
