Hulk Electro plus Block pad. Pad did not fit machine, spent hours trying......Contacted Evolution promised return call. Did not happen. Contacted FFX, supplier who in turn dealt with Evolution who could not make the pad they had in stock fit machine either!!! Second pad eventually arrived. This had been worked on to make a fit. Two additional holes drilled in clamp. Maintain lip on back of machine not deep enough for secure and safe clamping. Hulk tested OK with pad fitted, not used on Job yet which is now running two weeks late due to above issues. It has meant we are now working on the blocks in the weed growing season which will make re-sanding less likely to be effective. VERY disappointing Phil Hoyle
