Telehandlers are heavy duty work machinery produced specially to operate in rough environment. This however, does not mean they can be driven without regard on rough terrain. These kinds of machines have a a lot bigger risk of tipping over or load loss when they are traveling on slopes.
If you do have to travel on a slope, make certain that you proceed carefully and slowly while keeping the load low. Prior to getting on the slope, downshift to 4WD and a lower gear. Using the engine brake would help to control the telehandler's speed. Try not to turn on a slope if possible. If you have to make the turn, take it as wide as possible and utilize extreme care.
Always try to avoid driving across very steep slopes. Utilize 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 equipment is fairly heavy; therefore, it could be required to drive backwards up slopes. Once the telehandler is carrying a cargo, the front of the unit becomes the heavy end, and you would be able to back the machine down the slopes.
On a mixed jobsite, operator training is really important. The coordinated steering machinery, along with the rear-pivot machines usually operate on the same jobsite where everyone is permitted to operate all of the machinery. In this instance, an individual who is used to using a coordinated steer machinery could jump onto a rear-pivot machinery. A very significant difference between how these two units work has much to do with what part of the equipment extends outside of the turning radius.
