Top Plate Angle - Grizzly T23108 Owner's Manual

Top Plate Angle

It is necessary to have the correct backward top
plate angle from the side plate (see Figure 24)
to form the cutting point where the top and side
plates meet, which initiates the cut. This angle
continues the cut and forces wood chips away
from the kerf.

When setting up the sharpener, the top plate
angle is determined by the rotational angle of the
chain holder in relation to the grinding wheel.
The chain holder angle scale on the front of the
base (see Figure 25) has angle marks to the left
and right of 0°. The angle marks on the right side
of the scale are used when sharpening left-hand
cutters (see Left- & Right-Hand Cutters on
Page 18). Conversely, the angle marks on the left
side of the scale are used when sharpening right-
hand cutters.

Note: Always refer to the chain manufacturer's
specifications when setting up the sharpener.
However, if this information is not available, use
the chart in Figure 22 on Page 20 as a general
guide.

DISCONNECT MACHINE FROM POWER!
Loosen the chain holder lock knob.
Rotate the chain holder to align the mark on
the chain holder base with the angle mark on
that scale that is right for your chain, then re-
tighten the lock knob.
Tip: The chain holder is easier to rotate if the
holder tilt is at 0° (see Gullet Angle on Page
24 for detailed instructions).
