The tool is simply placed over the teeth of the kick starter driver and fixed through the two holes with long screw or bolt on the engine housing. The nut of the variator can then be easily loosened or fastened. Unfortunately, the required longer screws or bolts are not included and must be obtained yourself. This tool is better suited for work in the drive area than the piston stopper. The risk of piston damage is excluded here.
