Safety Warnings and Precautions
WARNING: WHEN USING TOOL, BASIC SAFETY PRECAUTIONS SHOULD ALWAS BE FOLLOWED TO
REDUCE THE RISK OF PERSONAL INJURYAND DAMAGE TO EQUIPMENT.
Read all instructions before using the tool.
1. Keep work area clean. Cluttered areas invite injuries.
2. Observe work area conditions. Do not use machines or power tools in damp or wet locations. Do not expose to
rain. Keep work area well lighted. Do not use electrically powered tools in the presence of flammable gases or
liquids.
3. Keep children away. Children must never be allowed in the work area. Do not let them handle machines, tools,
or extension cords.
4. Store idle equipment. When not in use, tools must be stored in a dry location to inhibit rust. Always lock up
tools and keep out of reach of children.
5. Use the right tool for the job. Do not attempt to force a small tool or attachment to do the work of a larger
industrial tool. There are certain applications for which this tool was designed. It will do the job better and
more safety at the rate for which it was intended. Do not modify this tool and do not use this tool for a purpose
for which it was non intended.
6. Dress properly. Do not wear loose clothing or jewelry as they can be caught in moving parts. Protective,
electrically non-conductive clothes and non-skid footwear are recommended when working. Wear restrictive
hair covering to contain long hair.
7. Use eye and ear protection. Always wear ANSI approved impact safety goggles. Wear a full face shield if you
are producing metal filings or wood chips.
8. Do not overreach. Keep proper footing and balance at all times. Do not reach over or across running machines.
9. 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
and authorized technician. The handles must be kept clean, dry, and free from oil and grease at all times.

Additional Safety Warnings
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 non-metal 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 over-tighten the Grinding Lock Cap(#9).Tighten it by hand only. Over-tightening may cause the wheel to
break or disintegrate.
4. Never use the Chainsaw Sharpener without the Grinding Wheel Cover(#11) 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.

Refer to theAssembly Drawing on page 10 and the various photographs.
NOTE: RAISE THE TOP HOUSING(#4) WHILE ADJUSTING THE CHAIN.
1. Clean the chain before sharpening. Wash it with a non-flammable solvent. Do not use gasoline. Dry the chain.
2. Lift up the Chain Stop(#23) and secure the chain in the Sliding Guides(#31). See FIGTURE 8.

4. See FIGTURE 7&8. Loose the Lock Wheel(#18) to allow entire housing to turn. Rotate the housing to match the
degree of angle you need on the Angle Gauge. Chinas come in various sizes with varying degrees of sharpening
angles. Check with your chain manufacture’s manual to determine what degree you need to sharpen at. Once the
degree is set, tighten the Lock Wheel(#18).
5. Lower the Top Housing(#4) so that the Grinding Wheel(#8) skims the chain tooth.
6. Hold it at that position while you tighten the Lock Stop(#6) so that the wheel will only go down to that point.
See FIGTURE 9.
7. Depending on the amount of material you wish to remove, tighten or loosen the Lower Knob(#26) and set the
Lock Nut. See FIGTURE 7. The Lower Knob(#26) has a Lock Nut which will determine how much material is
removed. Once you set the Lock Nut, fully tighten the Lower Knob(#26).
Lock Stop(#6)

8. Lock the chain in the Sliding Guides(#31) by turning the Handle(#34). See FIGTURE 10. The Handle(#34)
should be situated so that you can easily release and tighten it. You will need to release it each time you move to
the next link, and tighten it to sharpen each link.
Limiting Gauge
Handle (#34)
Fig 10
9.If the chain has been repeatedly sharpened, the chain depth limiting gauges may need to be taken down with a
flat file(not included). See FIGTURE 10&11. File down each gauge so that they are at a lower level than the
cutting teeth.
Fig. 11
Sharpening
1. Put on your protective gear and make sure the immediate area is clear of bystanders.
2. Plug in the Power Cord(#3) and push the green button on the Switch Plate(#5) to turn on the machine.
3. Slowly lower the grinding wheel as shown in FIGTURE 12. If you notice slight errors in your settings, turn off
the unit and unplug it before you make your adjustments.
Fig.12
NOTE: AGOOD GRIND OCCURS WHEN THE CONTACT BETWEEN THE WHEEL AND THE TEETH ARE
GRADUALAND SMOOTH. DO NOT STOP TOO LONG ON EACH TOOTH.
4. After sharpening one tooth, turn off the machine. Lift the Top Housing(#4), release the Handle(#34), and move
the chain so that the next link is positioned in the Chain Stop(#23). Tighten the Handle(#34). Turn the machine
back on and continue sharpening the next tooth. Repeat this process until you have sharpened all of the links set
up for this angle.
5. After you finished sharpening all of the teeth set for your current angle, turn off the machine by pushing the
black button in the Switch Plate(#5) and unplug the unit. See FIGTURE 11.
6. Loosen the Lock Wheel(#18) and reset the angle so that the first tooth that hasn’t been sharpened is positioned
against the Chain Stop(#23) and locked in as explained on page 6.
7. As you did with the first half of the chain, be sure to lower the Top Housing(#4) so that the Grinding Wheel(#8)
skims the chain tooth, and lock it in place. See page 6. Follow all of the steps on page 6 double checking
everything before you plug in the machine and turn it on again.
WARNING: REMEMBER TO TURN OFF THE MACHINE AND UNPLUG IT IF YOU NEED TO NAKE ANY
ADJUSTMENTS.
8. After you repeat all of steps under Sharpening on page 7, your chain is ready to be mounted on your saw.
Maintenance
1. Keep the Sharpener clean and free of dust, metal debris and dirt.
2. Check the Grinding Wheel before each use to make sure it isn’t damaged. 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 non metal object(Ie: screwdriver handle). If it is in good condition it
will produce a metallic sound.A dull sound indicates a crack or break.
3. Replace the Grinding Wheel when it grinds down to a diameter of 3 inches.
