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
time and after changing the grinding wheel. Switch o the
product immediately if the grinding wheel is no longer round
or irregular, considerable vibration occurs or you notice
abnormal noise.
