Grinding Wheel Warnings.
1. Do not use a grinding wheel if it is chipped, cracked, or worn. You can check if the wheel has cracks not
visible to the human eye by hanging it up by the central hole and tapping it with a nonmetallic object (ie:
screwdriver handle). If it is in good condition it will produce a metallic sound. A dull sound indicates a
crack or break.
2. Only use grinding wheels that fit the Arbor (7/8”). Do not try to change or modify the mounting hole on a
grinding wheel to make it fit. Grinding wheel replacements are available at Harbor Freight Tools.
3. Do not overtighten the Grinder Lock Cap (9). Hand tighten it only. Overtightening may cause the wheel
to break or disintegrate.
4. Never use the Chainsaw Sharpener without the Grinding Wheel Cover (11B) in place.
5. Always test the Grinding Wheel (8) by running it for a minute prior to contact with a chain.
6. Keep away from the wheel when it is turning, and make sure no one is standing close, in the line of the
wheel rotation trajectory.
7. If the grinding wheel vibrates, turn off the machine immediately and check that it is mounted securely,
and that is not damaged.
8. Never try to stop the grinding wheel with your hands, even if you are wearing safety gloves. The wheel
will cut through gloves and your hand, causing serious injury.
9. Never operate tool without the Grinding Wheel Cover in place.
10. Replacement grinding wheel listed speed must meet or exceed RPM rating of the tool.
Warning!! This machine is designed to sharpen chainsaw chains. Do not attempt to sharpen any other tools, and
do not attempt to grind any other objects.
