• Make sure the engine is free of dirt and de-
bris.
• Check fuel level. Refer to “Engine Manual”
for correct fuel for your requirements.
• For best results, use only clean, fresh, unleaded
gasoline with an octane rating of 87 or higher
((R+M)/2 rating method).
• Do Not use ethanol blends of gasoline (such
as E15 or E85) with more than 10% ethanol
by volume. Performance problems and/or
engine damage may result which may not be
covered under warranty.
• Do Not use gasoline containing methanol.
Do not fill fuel tank while engine is
running. Allow engine to cool several
minutes before adding fuel. If fuel is
spilled, do not start engine and avoid
creating a source of ignition until the
fuel is wiped clean and evaporated.
• Check tire pressure (see page 28). Improper
pressure will adversely affect traction, steer-
ing and level cutting height.
• Check tires for damage or cracking.
• Check hydrostatic pump drive belt for dam-
age or cracking.
• Check mower deck belt for damage or crack-
ing.
• Check mower deck level.
• Check to ensure blades are sharp and se-
cure; the cutting edge should be positioned
in the direction of blade rotation (clockwise
as viewed from top of mower deck).
• Adjust cutting height if necessary.
• Check operation of park brake (see "Park
Brake Adjustment" page 34).
• Remove grass and debris from machine.
• Test safety interlock systems (see chart be-
low). Perform these tests in a clear open
area and keep bystanders away. If there is a
malfunction during one of these procedures,
DO NOT operate machine. (See your Grass-
hopper dealer).
