E-2ECGCNG-I-0513 Getting started with your new grinder 1. Loading tools Lean the machine back on the handle to expose the work area and load the proper tools for your job. Electric machines should be unplugged, gas machines should have the spark plug wire removed. Once all tools are in the proper position return the machine to upright. Remember if you are using tools with PCD’s on Stripserts they have a leading edge and must be loaded as such. Also, remember both of the discs turn in direction of arrows.
