GRINDING JIP

The grinding jig provided with the wet sharpener is used for securing a variety is used for securing a variety of tools, and can be positioned to grind with and against the wheel rotation.

Water Reservoir

• The wet sharpener is designed for wet grinding and should never be used without water.
• The mounting tabs on the reservoir serve as hooks to attach to the reservoir mounting slots.

To fill and position the reservoir:

• Remove the reservoir and fill it with water just below the V-shaped notch.
• Attach the reservoir to the sharpener.

To mount the grinding jig:

• DISCONNECT THE SHARPENER FROM THE POWER!
• Slide the grinding jig onto the universal support, as illustrated.
• Insert the tool into the jig clamp, then use the angle guide, as described in the manual, to set the grinding angle.
• Once the grinding angle is set, tighten both lock knobs to secure the tool in place.

NOTE:

• If the sharpener is not going to be used immediately, do not put the grinding wheel in the water.
• Remove the reservoir to reduce the likelihood of damage to the wheel and potential hazards from being stored in water.

CAUTION:

• Always lock the switch “OFF” when the sharpener is not in use.

Here are some tips for using the sharpener water reservoir:

• Check the water level before every use and be sure the wheel is wet before you begin grinding. DO NOT use the sharpener without water.
• Leaving the grinding wheel stored in water will cause damage to the wheel and create potential hazards because the wheel will become unbalanced.
• Once any grinding process is complete, return the reservoir to the storage position to prevent prolonged water exposure to the wheel.
• Empty, rinse, and refill the reservoir regularly. This prevents metal and stone from accumulating in the reservoir.
• Place a magnet in the reservoir to catch and collect metal fillings. This will help prevent excessive metal accumulation on the grinding wheel.

Angle Guide

The sharpener comes with an angle guide to help identify and maintain the cutting angle on a variety of tools.

1. Mount the blade in the Grinding Jig and place the support arm in the mount.
2. Use the gauge on the outside of the angle guide to measure the bevel angle of the blade.
3. Loosen the locking knob on the angle guide and adjust the protractor so that the arrows are aligned with the correct grindstone diameter marking.
4. Then set the pointer to the required bevel angle on the blade and tighten the locking collar to lock in position.
5. Thread the grinding jig onto the support arm so that the blade rests against the grindstone.
6. Position the curved foot of the angle guide on the grindstone and the flat section of the pointer on the blade to be sharpened.
7. Use the Support Arm Height Adjuster to adjust the height of the support arm until the flat section on the angle guide pointer lies perfectly flat on the blade.
8. The grinding angle will now be correct.

Wheel Dressing

• Depending on the type of grinding you do, the grinding wheel may require periodic dressing.
• A variety of dressing tools are available (not included) and can be used to restore the abrasive quality of the wheel surface and bring the wheel edge back to the right form.
• Refer to the instructions that accompany your dressing accessory for complete details on how to properly dress a wheel.
• When grinding, metal objects become heated quickly. It is important to keep moving the object back and forth across the face of the grinding wheel and to cool the object frequently using the coolant tray.

Sharpening

• The leather stropping wheel on the sharpener and the included abrasive stropping paste can be used to obtain a razor-sharp edge on many tools.
• Before use, the stropping wheel must be properly prepared.

NOTE:

• A slight wobble of the stopping wheel, when it is rotating, is normal and does not affect the performance.

To prepare the stropping wheel:

• Evenly apply a light machine oil to the leather wheel. Use enough oil to provide a thorough coating, but not so much as to saturate the leather and result in dripping.
• Apply a thin coat of abrasive honing paste the leather wheel using a wooden spreader or similar device. Distribute the paste evenly by hand-turning the wheel while spreading.
• Connect the machine to power, then turn the machine on and continue to distribute the paste, still using the wooden spreader. Move the spreader lightly in a circular motion across the wheel.
• Once the paste is evenly distributed, begin sharpening.
• These preparations will be sufficient for sharpening five to ten tools. If you notice a drop in sharpening performance or have sharpened more than ten tools, repeat the above steps.
