Before Operating
1. Review and understand the contents of the Opera-
tor’s Manual and Operator Training DVD before starting
and operating the machine. Become familiar with the
controls and know how to stop the machine and engine
quickly. A r eplacement Operator’s Manual is available
on the Internet at www.Toro.com.
2. Keep all shields, safety devices and decals in place.
If a shield, safety device or decal is defective, illegible or
damaged, repair or replace it before operating the ma-
chine.
3. Tighten any loose nuts, bolts or screws to ensure
machine is in safe operating condition.
4. Assure interlock switches are adjusted correctly so
engine cannot be started unless both drive handles are
in the neutral lock p osition, the PTO switch is OFF (dis-
engaged) and either the seat is occupied or the parking
brake is applied.
5. Since fuel is highly flammable, handle it carefully:
A. Store fuel in containers specifically designed for
this purpose.
B. Do not remove machine fuel tank cap while en-
gine is hot or running.
C. Do not smoke while handling f uel.
D. Fill fuel tank outdoors and only to within an inch of
the top of the tank, not the filler neck. Do not o verfill.
E. Replace fuel tank and fuel container caps secure-
ly after refueling machine.
F. If fuel is spilled, do not attempt to start the engine
but move the machine away from the area of the spill-
age. Avoid creating any source of ignition until fuel
vapors have dissipated. Wipe up any spilled f uel.
While Operating
1. Sit on the seat when starting and operating the ma-
chine.
2. Before starting the engine:
A. Engage the parking brake.
B. Make sure both drive handles are in the neutral
lock position and the PTO switch is OFF (disen-
gaged).
C. After engine is started, release parking brake and
keep both drive handles in the neutral lock position.
Machine must not move. If movement is evident, the
traction linkage is adjusted incorrectly; therefore,
shut engine off and adjust traction linkage until ma-
chine does not move when both drive handles are in
the neutral lock position.
3. Do not run engine in a confined area without ade-
quate ventilation. Exhaust fumes are hazardous and
could possibly be deadly.
4. Do not touch engine, radiator or exhaust system
while engine is running or soon after it is stopped. These
areas could be hot enough to cause burns.
5. Before getting off the seat:
A. Ensure that both drive handles are in the neutral
lock position.
B. Lower and disengage cutting deck (or imple-
ment) and wait for all movement to stop.
C. Set parking brake.
D. Stop engine and remove key from ignition switch.
6. Anytime t he machine is parked (short or long term),
the cutting deck (or implement) should be lowered to the
ground. This relieves pressure from the lift circuit and
eliminates the risk of the cutting deck (or implement) ac-
cidentally lowering to the ground.
7. Do not park on slopes unless wheels are chocked or
blocked.
