corners, shrubs, trees, or other objects that may
obscure vision.
SLOPE OPERATION
1. Slopes are a major factor related to slip and fall
accidents, which can result in severe injury. All
slopes require extra caution. If you feel uneasy on
a slope, DO NOT mow it.
2. Mow across slopes, never up-and-down. Exercise
extreme CAUTION when changing directions on
slopes. DO NOT mow steep slopes or other areas
where stability or traction is in doubt.

This manual contains safety information to make you aware of the hazards
and risks associated with the machine and how to avoid them. This machine
is designed and intended to be used and maintained according to the
manual for finish cutting of established lawns and is not intended for any
other purpose. It is important that you read and understand these
instructions thoroughly before attempting to start or operate this equipment.
Engine Power Rating Information
The gross power rating labels for individual gas engine models meet or exceed SAE (Society of Automotive
Engineers) code J1940 (Small Engine Power & Torque Rating Procedure) and rating performance has been
obtained and corrected in accordance with SAE J1995 (Revision 2002-05). Actual gross engine power may be
lower and is affected by, but not limited to, ambient operating conditions and engine to engine variability. Given
both the wide array of products on which engines are placed, and the variety of environmental issues applicable
to operating the equipment, the gas engine will not develop the rated gross power when used in a given piece
of power equipment (actual “on-site” or net horsepower). This difference is due to a variety of factors including,
but not limited to, accessories (air cleaner, exhaust, charging, cooling, carburetor, fuel pump, etc.), application
limitations, ambient operating conditions (temperature, humidity, altitude), and engine to engine variability.
