G8220 Wet/Dry Bench Grinder -7 Site Considerations Notes BENCH MOUNTING Your G8220 Wet/Dry Grinder is designed to be used on a workbench. Make sure it is positioned at a comfortable working height. The machine can be permanently mounted to a bench by removing the base and using the four holes in the motor body to secure it directly to the surface of a bench. WORKING CLEARANCES Working clearances can be thought of as the distances between machines and obstacles that allow safe operation of every machine without limitation. Ensure that your working area offers plenty of room for free movement and a substantial amount of distance between you and others that may be working in your shop space. LIGHTING AND OUTLETS Lighting should be bright enough to eliminate shadow and prevent eye strain. Electrical circuits should be dedicated or large enough to handle combined motor amp loads. Outlets should be located near each machine so power or extension cords are not obstructing high-traffic areas. Be sure to observe local electrical codes for proper installation of new lighting, outlets, or circuits. Make your shop “child safe”. Ensure that your workplace is inaccessible to youngsters by closing and locking all entrances when you are away. Never allow visitors in your shop when assembling, adjusting or operating equipment. -8-G8220 Wet/Dry Bench Grinder SECTION 4: ASSEMBLY Water Reservoir Insert the water valve into the hole in the Water Reservoir.

G8220 Wet/Dry Bench Grinder -9 Tool Rest-Wet Wheel The large horizontally mounted wet grinding wheel also has a tool rest situated over it to aid the user in the grinding operations: 1. Position the two support brackets in the wide grooves which are located on each side of the water tray. The recess in the shape of a half circle should be facing outward on each side. See Figure 4. Figure 4. Mounting rest holder. 2. Thread a locking knob with washer through the hole in the bottom of the holder and into the water tray body. These knobs control the overall height of the tool rest assembly. 3. Set the tool rest into the half circle recesses. The sliding tool rest should already be assembled onto the holder, if it is not, slide the tool rest into the groove. It only goes one way as there is a tab preventing incorrect installation. The miter gauge also should already be positioned on the sliding tool rest. 4. Attach the tool rest assembly to the support brackets.

The dry wheel supplied with the G8220 is an 80 grit Aluminum Oxide wheel good for heavy material removal and for roughing in to approximate dimensions. The wet wheel is a very fine 1000 grit which, along with the water supply, allows fine grinding and honing to very precise edges....
