Operator's Manual Second Edition • First PrintingOperating Instructions62 Z®-60 DC • Z®-60 FE Part No. 1292373GTDriving on a slopeDetermine the uphill, downhill and side sloperatings for the machine and determine the slopegrade.Maximum slope rating, platformdownhill (gradeability):4WD: 45% (24°)Maximum slope rating, platformuphill:4WD: 45% (24°)Maximum side slope rating:25% (14°)Note: Slope rating is subject to ground conditionswith one person in the platform and adequatetraction. Additional platform weight may reduceslope rating. The term gradeability applies to thecounterweight uphill configuration only.Be sure the boom is below horizontal and theplatform is between the non-steer wheels.When the Machine On Incline indicator light is onand the tilt alarm sounds, the following functions areaffected; drive functions are disabled.Follow the Boom lowering procedure (seeOperating Instructions) to restore drive function.When the machine is stowed, on a slope, and the tiltalarm sounds, the following functions are affected;lift functions are disabled.Return the machine to level ground to restore liftfunctions.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 edge ofthe piece of wood and lift the end until the piece ofwood is level.While holding the piece of wood level, measure thevertical distance from the bottom of the piece ofwood 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.
