Telehandlers are heavy duty work machines produced specifically to work in rough terrain. This however, does not mean they can be driven without consideration on rough environment. These types of equipments have a a lot greater risk of tipping over or load loss when they are traveling on slopes.
When traveling on a slope, make certain that you move slowly with the machinery while also keeping the load low. Downshift to 4WD and a lower gear, before getting on the slope. Utilizing the engine brake would 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 care and take it as wide as possible.
Under any conditions, avoid driving across very steep slopes. Ascend and descend slopes with the telehandler's heavy end pointing up the incline. Even when the forks have no load, the counterweighted rear of the equipment is fairly heavy; thus, 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 machinery down the slopes.
Operator training is hugely essential on a mixed jobsite. Rear pivot equipment will usually operate on the same jobsite of coordinated steering equipment, where everybody is allowed to utilize all of the machinery. In this case, a person who is used to utilizing a coordinated steer machinery can jump onto a rear-pivot machine. A really key difference between how these two units work depends on what part of the equipment extends outside of the turning radius.
