Additional platform weight may reduceslope rating. The term gradeability applies to theplatform downhill configuration only.Be sure the boom is below horizontal and theplatform is between the non-steer wheels.Move the drive speed select switch to machine onincline symbol.To determine the slope grade:Measure the slope with a digital inclinometer ORuse the following procedure.You will need:• carpenter’s level• straight piece of wood, at least 3 feet/1 m long• tape measureLay the piece of wood on the slope.At the downhill end, lay the level on the top edgeof the piece of wood and lift the end until the pieceof wood is level.While holding the piece of wood level, measurethe vertical distance from the bottom of the pieceof wood to the ground.Divide the tape measure distance (rise) by thelength of the piece of wood (run) and multiply by100.Example:Piece of wood = 144 inches (3.6 m)Run = 144 inches (3.6 m)Rise = 12 inches (0.3 m)12 in ÷ 144 in = 0.083 x 100 = 8.3% grade0.3 m ÷ 3.6 m = 0.083 x 100 = 8.3% gradeIf the slope exceeds the maximum slope or sideslope rating, then the machine must be winched ortransported up or down the slope.
