Craftsman 247.795850 - Manual (Page 16)

NOTE: Use caution when removing the blade to avoid
contacting the weid boits on the housing.
• When sharpening the blade, follow the original
angle of grind 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 21.
CARBURETOR ADJUSTMENT
A
WARNING: IF ANY ADJUSTMENTS ARE
MADE TO THE ENGINE WHILE THE
ENGINE IS RUNNING (E.G. CARBURE­
TOR), KEEP CLEAR OF ALL MOVING
PARTS. BE CAREFUL OF HEATED SUR­
FACES AND MUFFLER.
The carburetor has been pre-set at the factory and
should not require adjustment. However, if your
engine does not operate properly due to suspected
carburetor problems, take your chipper-shredder to
your nearest SEARS Service Center.
• When reassembling the blade, tighten to between
550 and 650 inch pounds, or lacking torque
wrench, tighten securely.
FLAILS
The flails, located inside the housing, may be
reversed when they become dull. It is suggested that
this procedure be performed by your nearest Sears
Service Department.
ENGINE SPEED
Your engine speed has been factory set. Do not
attempt to increase engine speed or it may result in
personal injury. If you believe the engine is running
too fast or too slow, take your chipper-shredder to the
nearest SEARS Service Center for repair and adjust­
ment.
