NOTE: Use caution when removing the blade to avoid
contacting the weld bolts on the housing.
• When sharpening
the blade,
follow the original
angle of gdnd as a guide. It is extremely important
that each cutting edge receives an equal amount of
grinding to prevent an unbalanced blade. An unbal-
anced blade will cause excessive
vibration when
rotating at high speeds and may cause damage to
the unit.
• The blade can be tested for balance by balancing it
on a round shaft screwdriver or nail. Remove metal
from the heavy side until it is balanced evenly. See
figure 20.
