Cutting Height Adjustment; Checking The Adjustment; Mower Blade Adjustments - Craftsman 151.30377 Operation Manual

CUTTING HEIGHT ADJUSTMENT
See Figure 11.
[] Use the roller assembly to adjust the cutting height of
the mower to four positions, from 1- 2 inches (2.6 - 5.1
cm).
[] For the highest cutting leve!, move the adjustment
knobs to position A as shown in Fig. 11.
[] For the lowest cutting levet, move the adjustment
knobs to position B as shown in Fig. 11.
[] Set intermediate cutting heights by moving the
adjustment knobs to one of the two stops between
highest and towest positions.
NOTE: The two adjustment knobs MUST be set to the
same position (height).
For best performance, align the edge of the cutting
blades to overlap the previously cut path. This will
ensure no grass is missed during the process.
NOTE: Do not use wheels as a reference point for
grass cut line.
CHECKING THE ADJUSTMENT
See Figure 13.
[] Turn mower upside down.
[] Insert a piece of paper between cutting bar and one
of the reel blades, and slowly turn wheel by hand.
[] Each blade should cut across the paper in a
continuous line. If there are missed spots in the cut, it
is necessary to make further adjustments. See Mower
Blade Adjustments.
,_ CAUTION!
Do not overtighten adjustment
screws, as this could damage cutting bar. Both screws
must be tight on final adjustment.
MOWER BLADE ADJUSTMENTS
See Figure 12.
_!_ WARNING! Blades are extremely sharp.
To avoid injury, do not touch blades when making
adjustments.
NOTE: Blades are factory adjusted.
[] Misalignment can occur, often caused by blades
being too loose or too tight. This can cause an uneven
cut or difficulty pushing the mower.
[] Each end of the cutting bar is adjusted separately.
[] To move the cutting bar closer to the blades turn
the adjustment screw clockwise. To move the cutting
bar away from the blades turn the adjustment screw
counterclockwise.
[] When the space equals the thickness of paper (0.12
mm), insert a piece of paper between one of the blades
and the cutting bar, and slowly turn the wheel by hand.
[] The reel should cut the paper evenly at every point. If
not, it is necessary to readjust the cutting action.
_lb CAUTION! Adjusting the screws for blade
adjustments is a very sensitive procedure. A sixteenth
of a turn is considered a major adjustment. Before
tightening one adjustment screw, make sure to loosen
the opposite screw an equal amount.
