Maintenance toolkit
A toolkit of a few key items will allow most standards repairs on all models of risograph.
Tools
| Item | Notes |
|---|---|
| JIS Phillips #2 screwdriver | The screws in a risograph conform to the Japanese Industrial Standard (JIS), not ANSI (used in the US), or ISO (used in Europe).[1] Using a proper JIS screwdriver will provide more torque to stuck screws, and make it less likely that screws become stripped. A good option for this product is the: Vessel 220 P2 150 |
| Metric hex keys | These should be separate L-shaped wrenches, not part of a pocketknife-style connected set. The sizes needed (in millimeters) are: 5, 4, 3, 2.5, 2, and 1.5. |
| Small flat head screwdriver | Primarily for removing e-rings—a thin, strong blade is important. A small butter knife or type tweezers for letterpress make good substitutes. |
| Needle nose pliers | For reattaching e-rings, and manipulating light springs. |
| 5.5 mm socket wrench, crescent wrench, and/or nut driver | Many internal screws in the risograph have an external hex head profile of 5.5 mm. A small adjustable wrench will also do. |
| Small vice grips | For removing stuck screws. |
| Ruler (mm) and/or calipers | Mechanical calibrations for the risograph are invariably provided in metric. |
| Small flashlight | A magnetic flashlight is best; a headlamp or bike light will also do. |
| Fine point sharpie | For marking adjustable plates/screws before and after adjustment, or making notes inside the risograph. |
| Magnet or magnetic retrieval tool | For retrieving dropped screws and other parts. |
| Bristle brushes (nylon & brass) | For cleaning old grit and grease off of hard plastic and metal surfaces respectively. |
