The non-slip rubber feet provide stability during operation, and the wheel dressing stick ensures that the grinding wheel maintains its shape and sharpness over time.

Working Instructions

The direction of Grinding
It mainly depends on your requirements whether you want to work with or against the direction of grinding. If you want to quickly remove large quantities of steel (e.g. from very old, rusty tools) or if you want to grind coarse tools, such as axes, it is recommended to work against the direction of grinding. If you want to grind more precisely, we recommend to work with the direction of grinding. This applies, for example, to carving tools and knives. 

Please note: The grinding process is slowed down if you work with the direction of rotation. Please check before each operation whether the surface of the grinding stone is even. To do so, lower the universal support onto the stone and turn it manually by 360°. If required, trim uneven material using the 250 trimming device. Upon the time of delivery, the TiGer provides of even surfaces.

Water Reservoir 

1. Fill the water reservoir with water up to the marking. The grinding stone becomes saturated with water. Refill water, if required. Do not grind without water.

2. Once the grinding process is completed, lower the water reservoir to prevent the grinding stone from being in the water for an extended period of time.

3. Empty the water reservoir regularly. Otherwise, particles of steel and trimmed stone will accumulate and compress in the reservoir.

Expert tip: Such precipitations can be avoided if you place a magnet into the water.

Angle Measurer
Measure the angle of the grinding bezel by comparing the cutting edge to the notches. Then, you set the determined angle at the device by changing the height of the universal support. To do so, perform the following steps: First, clamp the tool into the device and insert the device on the universal support.
Then, hold the angle measure with the desired angle at the tooltip. Now, adjust the height of the universal support in such a manner that the front end of the angle measurer straight borders the grinding stone. Please make sure that the angle measure is always in alignment with the tooltip.

Note: The values indicated on the angle measurer are only standard values. Of course, you can change these values according to your requirements.

Grinding

Expert tip: New tools still show traces of the production process. You can substantially increase the lifetime of your tools if you grind them on both sides of the cutting edge before the first application. You simply grind the back side in the free-handed mode on the vertical of the grinding stone, and the front side is as follows.
After you have set the angle, insert the tool mounted in the device on the universal support, turn on the motor, and start the grinding process. Press the tool evenly onto the grinding stone near the cutting edge, and move it crosswise across the stone. Please make sure that at least half the width of the cutting edge comes into contact with the grinding stone at any time to avoid damage to the stone.

To achieve finer grinding results, prepare the stone using the Stone preparer. Thereby you increase the graining from 250 to approximately 1000. The SP is available as an accessory from your scheppach dealer.

Sharpening
Never sharpen against the direction of grinding! Otherwise, the tool will cut into the leather!
Impregnate the leather disc using weak machine oil. Then apply an abrasive paste on the leather disc. Turn on the device, and distribute the abrasive paste by pressing the ground tool with circular movements on the wheel. These preparations are sufficient for five to ten tools. Then, you start again with a new layer of machine oil, followed by new abrasive paste. These measures increase the lifetime of the leather and the quality of your tools.

Expert tip: You can work in the free-handed mode for the trimming itself. You achieve a more precise result if you keep the tool in the device in the position in which you ground the tool.
