Spark Arrestor

WARNING: This mower is equipped with an
internal combustion engine and should not
be used on or near any unimproved forest-
covered, brush-covered or grass-covered land
unless the engine's exhaust system is
equipped with a spark arrestor meeting
applicable local or state laws (if any).
If a spark arrestor is used, it should be maintained
in effective working order by the operator. In the
State of California the above is required by law
(Section 4442 of the California Public Resources
Code). Other states may have similar laws. Federal
laws apply on federal lands.
A spark arrestor for the muffler is available through
your nearest engine authorized service dealer or
contact the service department, P.O. Box 361131
Cleveland, Ohio 44136-0019.
Slope Gauge (Back Cover)
WARNING: Slopes are a major factor related
to slip and fall accidents which can result in
severe injury or death. All slopes require
extra caution. If you feel uneasy on the slope,
do not mow it. Do not mow on slopes greater
than 15 degrees (25%). Only mow across
slopes, never mow up and down slopes.
USE THE SLOPE GAUGE ON THE BACK COVER AS
SHOWN TO DETERMINE IF A SLOPE IS TOO STEEP
FOR SAFE OPERATION!
To check the slope, proceed as follows:
1. Open manual to 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.
4. Adjust gauge up or down until the left corner
touches the slope.
5. If there is a gap below the gauge, the slope is too
steep for safe operation.
