Replacing the Grinding Wheel
Check the grinding wheel before each use to make sure it's 
not damaged. Do not use a grinding wheel if it is chipped, 
cracked, or worn. You can check if the wheel has minor cracks 
by hanging it up by the central hole and tapping it with a non 
metal object (ie; screwdriver handle). A grinding wheel in good 
condition will produce a metallic sound. A dull sound indicates 
a crack or break.
Replace the grinding wheel when it grinds down to a outside 
diameter of 3 inches.
mWARNING! This cordless chain saw sharpener uses 
a standard 4.25 inch x 1/8 inch grinding wheel with 100 
grit. Only use the identical grinding wheels for replacement. 
Grinding wheels of other sizes may cause malfunction or 
personal injury. 
mCAUTION! Wear heavy duty gloves when handling with 
the grinding wheel. 
1.  Before handling the grinding wheel, turn o the machine 
and remove the battery. Wait until the grinding wheel 
comes to a complete stop. 
2.  Remove the 3 screws used for securing the grinding wheel 
guard, then remove the grinding wheel guard and expose 
the worn grinding wheel (Fig. 19). 
3.  To remove the worn grinding wheel, rotate the grinding 
wheel retainer counterclockwise (Fig. 20) to unlock, then 
take out the retainer and the worn wheel.
4.  Place the new grinding wheel in position, x it by the 
grinding wheel retainer. 
  NOTE: Examine the grinding wheel and adjust the 
tightness of the retainer to make sure the grinding 
wheel can rotate freely. DO NOT overtighten the  
grinding wheel retainer. 
5.  Replace the grinding wheel guard, x with the  
original screws. 
mCAUTION! Never operate a chain saw sharpener 
without a proper installed grinding wheel guard. 
NOTE: It's recommended to perform a test run for at least  
30 seconds with no load before using this product for the rst

product immediately if the grinding wheel is no longer round 
or irregular, considerable vibration occurs or you notice 
abnormal noise.
