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 tool. 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 product until they have read this manual and
have developed a thorough understanding of how it works.
Do not modify this product 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. This
product will be safer and do a better job at the capacity for which it was intended. DO NOT use
this equipment for a purpose for which it was not intended.
Industrial or commercial applications must follow OSHA requirements.
⚠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 product in confined work areas
may put you dangerously close to cutting tools and rotating parts.
Do not use the product where there is a risk of causing a fire or an explosion; e.g., in the presence
of flammable liquids, gases, or dust. The product can create sparks, which may ignite the
flammable liquids, gases, or dust.
Do not allow the product to come into contact with an electrical source. The tool is not insulated
and contact will cause electrical shock.
Keep children and bystanders away from the work area while operating the tool. Do not allow
children to handle the product.

⚠WARNING
PERSONAL SAFETY
Stay alert, watch what you are doing, and use common sense when operating the tool. 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 tool 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 ANSI Z87.1 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.
Do not use the tool when tired or under the influence of drugs, alcohol or medication.
Remove keys or wrenches before connecting the tool to an air supply, power supply, or turning on
the tool. A wrench or key that is left attached to a rotating part of the tool may cause personal
injury.
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
PRODUCT USE AND CARE
Do not force the product. Products are safer and do a better job 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 product will operate properly
and perform its intended function. Replace damaged or worn parts immediately. Never operate the
product with a damaged part.
Do not use a product with a malfunctioning switch. Any power tool that cannot be controlled with
the power switch is dangerous and must be repaired by an authorized service representative
before using.
Disconnect the power/air supply from the product and place the switch in the locked or off position
before making any adjustments, changing accessories, or storing the tool. Such preventive safety
measures reduce the risk of starting the tool accidentally.

Inspect the tool for good working condition prior to storage and before re-use.
Use only accessories that are recommended by the manufacturer for use with your product.
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.

Assembly Instructions
1. First determine what size stone is required to sharpen your chain. To do this, refer to your chainsaw
owner’s manual, your chainsaw instruction manual, or contact your chainsaw manufacturer. The size
and pitch of the chain is often stamped or printed on the chainsaw’s bar.
2. This sharpener comes with 3 different size stones:

Page 7 of 14
5/32” (smallest diameter stone) fits saws with 1/4 pitch or 3/8”s low profile chain
3/16” (medium diameter stone) fits saws with .325 pitch chain
7/32” (largest diameter stone) fits saws with 3/8” pitch chain
3. You can identify the size of each stone by sizing it with the multi-wrench included. Once you have
identified the correct stone for your chainsaw, remove the collet cap from the end of your sharpener
(see photo).
4. Attach the correct sharpening stone by slowly turning the chuck while simultaneously pressing the
lock button until it engages. See the following photo:
5. Open the chuck and insert the shank of the sharpener. Make sure to leave approximately 1/4” of
the shank exposed between the chuck cap and the stone.

6. Tighten the chuck using the provided multi-wrench.
7. Screw on the chainsaw’s sharpening guide and adjust:
8. The sharpening guide must be adjusted up or down on the mounting plate so the correct amount of
the stone’s diameter will be exposed.
9. To adjust the stone to the correct depth, loosen the screws on the mounting plate of the sharpening
guide.
10. Place the multi-wrench on its side with the four round notches down upon the face of the
sharpening guide. The four notches correspond to the different stone sizes (5/32”, 3/16”, 7/32”, and
4.5mm).
11. Position the correct size notch over the stone seated in the aperture of the chain guide. Adjust as
described previously and you’re now ready to sharpen.

Before Each Use
⚠WARNING
Double check the lock nut for correct, secure grinding-stone installation before each use.
Operating Instructions
⚠WARNING
Wear ANSI Z87.1 compliant safety goggles.
Do not use grinding wheels that have a max RPM less than the marked RPM rating on the tool.
Keep hands clear from grinding wheel during use.
Electric shock hazard. Do not expose to rain or use in damp locations.
Do not use for wet grinding.
Do not use wheel if cracked or chipped.

Follow manufacturer’s current specifications for correct filing angles.
Excessive depth-gauge settings or incorrect filing angles can increase the risk of kickback, which
can cause serious injury to the operator or bystanders.
Place your saw on a flat, solid, stable surface so it will not move or slide around during the sharpening
process. The chain tension should be adjusted to the manufacturer’s specifications.

Page 10 of 14
Always sharpen the saw away from your body. Sharpen chainsaw’s cutting teeth or cutters as shown
below. The sharpening guide should lay flat on the chain with the stone positioned in the cutter at the
angle recommended by the manufacturer. Use the guide lines on the top of the sharpening guide for
reference.
When sharpening, use two or three light strokes back and forth with the sharpener. Let the sharpener
and stone do the work. Sharpen all cutters equally.
When all the teeth on the top of the bar have been sharpened, use a glove or rag to advance the
chain by pulling towards the end of the bar. Sharpen remaining cutters evenly.
After Each Use
Let the tool cool down and place it in a clean, dry place after use.
Maintenance
Maintain the sharpener by adopting a program of conscientious repair and maintenance in
accordance with the following recommended procedures. It is recommended that the general
condition of any tool be examined before it is used. Keep your tool in good repair. Keep all 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. The following
chart is based on a normal operation schedule.
Maintenance Interval
