2 mm
Always mount the grinder securely, either to a bench
or to the optional stand .
Bench-mounting offers you flexibility and the ability
to sharpen chains virtually anywhere using a 12V
power source .
WARNING If included, place the power
converter where there is as little dust as possible
and out of reach of sparks from the machine .
Note: The chain weight and the power converter are
optional accessories, see section 8, "Accessories
and Spare Parts" .

4 .5 Install and center the grinding wheel

Note: The first step in preparing the grinder for use
is installing and centering the appropriate grinding
wheel .
The grinder comes with two wheel sizes: 3 .2 mm,
6 .4 mm . The wheels are 150 mm in diameter with
16 mm arbor size . It is critical to select the wheel of
the appropriate thickness for each chain .
The correct wheel size for a particular saw chain can
be found in this manual or at the back of the chain
packaging .

WARNING Inspect the grinding wheel and
make sure that it is not cracked or damaged . There
is a simple test (called the "ring test") that you can
do to check for damage to a grinding wheel . Hold
the grinding wheel up by its center hole . Knock the
edge of the grinding wheel gently with a non-metallic
object (like the plastic handle of a screwdriver) . If the
grinding wheel makes a dull, non-metallic noise,
then the wheel could be damaged . DO NOT USE IT .
CRACKED GRINDING WHEELS MUST BE
REPLACED IMMEDIATELY . See also section 6 .3,
"Change the grinding wheel and fit the grinding
wheel guard" .
Once the grinding wheel has been verified, you're
ready to begin the install .
