Telehandlers are machines that are meant to work in rough terrain, although, that doesn't mean that they could be driven without any consideration for the terrain. These equipments have a much bigger risk of load loss or tipping over when they are traveling on slopes.
If you do have to travel on a slope, make certain that you proceed slowly and carefully while keeping the load low. Prior to getting on the slope, downshift to 4WD and a lower gear. Using the engine brake will actually 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 not to drive across excessively steep slopes. Utilize the telehandler's heavy end pointing up the incline, when descending and ascending slopes. Even when the forks have no load, the counterweighted rear of the equipment is quite heavy; therefore, it could 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 could back the machine down the slopes.
On a mixed jobsite, operator training is really vital. The coordinated steering equipment, along with the rear-pivot machines often operate on the same jobsite where everyone is permitted to operate all of the machines. In this case, a person who is used to operating a coordinated steer equipment can jump onto a rear-pivot machinery. A really significant difference between how these two units operate depends on what part of the machine extends outside of the turning radius.
