Slope Gauge
USE THIS SLOPE GAUGE TO DETERMINE
IF A SLOPE IS TOO STEEP FOR SAFE OPERATION!
To check the slope, proceed as follows:
1. Remove this page and fold along the dashed line.
2. Locate a vertical object on or behind the slope (e.g. a pole, building,
fence, tree, etc.)
3. Align either side of the slope gauge with the object (See Figure 1 and Figure 2 ).
4. Adjust gauge up or down until the left corner touches the slope (See Figure 1 and Figure 2).
5. If there is a gap below the gauge, the slope is too steep for safe operation (See Figure 2 above).
WARNING! Slopes are a major factor related to tip-over and roll-over accidents which can result in severe
injury or death.
Do not operate machine on slopes in excess of 15 degrees. All slopes require extra caution.
Always mow across the face of slopes, never up and down slopes.

Mowing
Mowing Tips
• Make sure to clear the area of stones, sticks,
branches, wire and other debris that the blade
could hit.
• Never deliberately mow over any object. Avoid
striking solid objects with the blade.
• If the machine strikes an object or starts to
vibrate, immediately stop the engine,
disconnect the wire from the spark plug, and
examine the machine for damage.
• For best performance, install a new blade
before the cutting season begins.
• Replace the blade when necessary with a
Saber Edge replacement blade.
Cutting Grass Tips:
• Cut only about a third of the grass blade at a
time. Do not cut below the 3
rd
setting (2 inch)
unless the grass is sparse or it is late fall when
grass growth begins to slow down.
Refer to Adjusting the Cutting Height.
• When cutting grass over 6 inches tall, mow
at the highest cutting height setting and walk
slower; then mow again at a lower setting for
the best lawn appearance. If the grass is too
long, the machine may plug and cause the
engine to stall. Mow only dry grass or leaves.
Wet grass and leaves tend to clump on the yard
and can cause the machine to plug or the
engine to stall. Cut the grass more frequently.
• Overlap cutting swaths instead of cutting a full
swath with each pass.
• For extremely heavy cutting, reduce the width
of cut by overlapping previously cut path and
mow slowly.
• Pores in cloth grass catchers can become filled
with dirt and dust with use and catchers will
