Maintain tools with care. Keep tools sharp and clean for better and safer performance. Follow
instructions for lubricating and changing accessories. Inspect tool cords periodically and, if damaged,
have them repaired by an authorized technician.The handles must be kept clean, dry, and free from oil
and grease at all times.
10. Avoid unintentional starting. Be sure the switch is in the Off position when not in use and before
plugging in.
11. Stay alert. Watch what you are doing, use common sense.Do not operate any tool when you are tired.
12. Check for damaged parts. Before using any tool, any part that appears damaged should be carefully
checked to determine that it will operate properly and perform its intended function. Check for alignment
and binding of moving parts; any broken parts or mounting fixtures; and any other condition that may
affect proper operation. Any part that is damaged should be properly repaired or replaced by a qualified
technician.Do not use the tool if any switch does not turn On and Off properly.
13. Guard against electric shock. Prevent body contact with grounded surfaces such as pipes, radiators,
ranges, and refrigerator enclosures.
14. Replacement parts and accessories. When servicing, use only identical replacement parts.Use of any
other parts will void the warranty. Only use accessories intended for use with this tool. Approved
accessories are available from Harbor FreightTools.
15. Do not operate tool if under the influence of alcohol or drugs. Read warning labels on prescriptions
to determine if your judgment or reflexes are impaired while taking drugs. If there is any doubt, do not
operate the tool.
16. Use proper size and type extension cord. If an extension cord is required, it must be of the proper size
and type to supply the correct current to the tool without heating up. Otherwise, the extension cord could
melt and catch fire, or cause electrical damage to the tool.This tool requires use of an extension cord of
0 to 10 amps capability (up to 50 feet), with wire size rated at 18 AWG. Longer extension cords require
larger size wire. If you are using the tool outdoors, use an extension cord rated for outdoor use (signified
by “WA” on the jacket).

birth defects or other reproductive harm. (California Health & Safety Code § 25249.5, et seq.)
Note: Performance of this tool (if powered by line voltage) may vary depending on varia-
tions in local line voltage. Extension cord usage may also affect tool performance.

cannot cover all possible conditions and situations that may occur. It must be under-
stood by the operator that common sense and caution are factors which cannot be

Additional Safety Warnings
GrindingWheelWarnings.
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.
3.
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 FreightTools.
Do not overtighten the Grinder Lock Cap (9). Hand tighten it only. Overtightening may cause the wheel
to break or disintegrate.
4.
5.
6.
Never use the Chainsaw Sharpener without the GrindingWheel Cover (11B) in place.
Always test the GrindingWheel (8) by running it for a minute prior to contact with a chain.
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.
8.
9.
If the grinding wheel vibrates, turn off the machine immediately and check that it is mounted securely,
and that is not damaged.
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.
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.
