Important Safety Information
⚠WARNING
Read and understand all instructions. Failure to follow all instructions may result in serious injury
or property damage.
The warnings, cautions, and instructions in this manual cannot cover all possible conditions or
situations that could occur. Exercise common sense and caution when using this sharpener.
Always be aware of the environment and ensure that the tool is used in a safe and responsible
manner.
Do not allow persons to operate or assemble the sharpener until they have read this manual and
have developed a thorough understanding of how it works.
Do not modify this sharpener in any way. Unauthorized modification may impair the function
and/or safety and could affect the life of the product. There are specific applications for which the
product was designed.
Use the right tool for the job. DO NOT attempt to force small equipment to do the work of larger
industrial equipment. There are certain applications for which this equipment was designed. It will
be safer and do a better job at the capacity for which it was intended. DO NOT use this sharpener
for a purpose for which it was not intended.
Industrial or commercial applications must follow OSHA requirements.
⚠WARNING
This product may contain chemicals known to the State of California to cause cancer, birth defects or
other reproductive harm.
⚠WARNING
WORK AREA SAFETY
Inspect the work area before each use. Keep work area clean, dry, free of clutter, and well-lit.
Cluttered, wet, or dark work areas can result in injury. Using the sharpener in confined work areas
may put you dangerously close to other cutting tools and rotating parts.
Do not use the sharpener where there is a risk of causing a fire or an explosion; e.g., in the

Page 5 of 12
presence of flammable liquids, gases, or dust. The product can create sparks, which may ignite
the flammable liquids, gases, or dust.
Keep children and bystanders away from the work area while operating the tool. Do not allow
children to handle the sharpener.
⚠WARNING
PERSONAL SAFETY
Stay alert, watch what you are doing, and use common sense when operating the sharpener. Do
not use the tool while you are tired or under the influence of drugs, alcohol, or medication. A
moment of inattention while operating the sharpener may result in serious personal injury.
Dress properly. Do not wear loose clothing, dangling objects, or jewelry. Keep your hair, clothing
and gloves away from moving parts. Loose clothes, jewelry, or long hair can be caught in moving
parts. Air vents on the tool often cover moving parts and should be avoided.
Wear the proper personal protective equipment when necessary. Use ANSIZ87.1 compliant safety
goggles (not safety glasses) with side shields, or when needed, a face shield. Use a dust mask in
dusty work conditions. Also use non-skid safety shoes, hardhat, gloves, dust collection systems,
and hearing protection when appropriate. This applies to all persons in the work area.
Do not overreach. Keep proper footing and balance at all times.
Secure the work with clamps or a vise instead of your hand when practical. This safety precaution
allows for proper tool operation using both hands.
⚠CAUTION
SHARPENER USE AND CARE
Do not force the sharpener. Products do a better job and are safer when used in the manner for
which they are designed. Plan your work, and use the correct product for the job.
Check for damaged parts before each use. Carefully check that the sharpener will operate
properly and perform its intended function. Replace damaged or worn parts immediately. Never
operate the sharpener with a damaged part.
Store the sharpener when it is not in use. Store it in a dry, secure place out of the reach of
children. Inspect the sharpener for good working condition prior to storage and before re-use.
Use only accessories that are recommended by the manufacturer for use with your sharpener.
Accessories that may be suitable for one product may create a risk of injury when used with
another tool. Never use an accessory that has a lower operating speed or operating pressure than
the tool itself.
Keep guards in place and in working order. Never operate the unit without the guards in place.

Operating Instructions
⚠WARNING
Wear ANSI Z87.1 compliant safety goggles, hearing protection, a NIOSH compliant dust mask,
and work gloves when operating the machine.
Do not use grinding wheels that have a Max RPM less than the marked RPM Rating on the tool.

NEVER use without a wheel guard installed.
Install the sharpener onto chainsaw chain bar (centered).
Note: This machine is equipped with a safety switch with a release coil.
The provided power cables are complete with terminals for quick and safe connection to any 12V
battery. This allows the operator to use this sharpener on-the-job or in-the-field, wherever a 12V
battery is available.
Running the Machine
1. Make sure you have read the safety instructions at the beginning of the manual and that the
machine is set up properly.
2. Make sure all tools and objects used during set up are cleared away from the machine.
3. Turn the machine ON (push the "|" button).
4. Listen to and watch for abnormal noises or actions. The machine should run smoothly with little or
no vibration or rubbing noises. Strange or unusual noises should be investigated and corrected
before operating the machine further. Always disconnect the machine from power when
investigating or correcting potential problems.
5. Turn the machine OFF (push the "O" button).
Maintenance
⚠WARNING
Make sure this sharpener is disconnected from its power source before attempting any maintenance,
cleaning, or inspection.
Maintain your tools. It is recommended that the general condition of any tool be examined before
it is used. Keep your tools in good repair by adopting a program of conscientious repair and

Page 9 of 12
maintenance in accordance with the recommended procedures found in this manual. If any
abnormal vibrations or noise occurs, turn the tool off immediately and have the problem corrected
before further use. Have necessary repairs made by qualified service personnel.
Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are
less likely to bind and are easier to control. Keep handles dry, clean, and free from oil and grease.
Use only soap and a damp cloth to clean your tools. Many household cleaners are harmful to
plastics and other insulation. Never let liquid get inside a tool.
Always disconnect from the power source before carrying out any maintenance, lubrication, or
cleaning operations.
Keep the sharpener clean using a cloth rag with soap and water. Always dry after cleaning.
Never use compressed air for cleaning. It can cause wood or metal dust to reach small areas in
the sharpener, causing damage to essential components of the sharpener.
