danger of suddenly sliding sideways or down the hill. On moderate hills reduce speed and use caution. When operating on a slope, travel across the grade, whenever possible, not an up or down pattern. Reduce speed and exercise extreme caution on slopes and in sharp turns to prevent tipping or loss of control. Be especially cautious when changing direction on slopes. When pointing up a slope, the Sentar has the most weight on the drive wheels and therefore the most traction at the tires.
WARNING WARNING Operation in Reverse: Hydraulic Safety: Always keep a firm grip on the stationary handlebar with both hands. Keep both feet firmly on the foot platform. Operate the mower very slowly, inching it backward until you become familiar with how the mower operates and always if in an awkward location or position. Never place your foot or feet on the ground near the back edge of the mower while backing up to prevent serious injury to feet or legs if mower were to run over you.
