Safety
Hazard control and accident prevention are dependent
upon the awareness, concern, and proper training of
the personnel involved in the operation, transport,
maintenance, and storage of the machine. Improper
use or maintenance of the machine can result in injury
or death. To reduce the potential for injury or death,
comply with the following safety instructions.
Before Operating
1. Read and understand the contents of this Operator ’s
Manual before operating the machine. Become
familiar with all controls and know how to stop
quickly. A free replacement manual is available by
sending complete Model and Serial Number to:
The Toro Company
8111 Lyndale Avenue South
Minneapolis, Minnesota 55420–1196
2. Never allow children to operate the machine. Do not
allow adults to operate machine without proper
instruction. Only trained operators who have read this
manual should operate this machine.
3. Never operate the machine when under the influence
of drugs or alcohol.
4. Remove all debris or other objects that might be
picked up and thrown by the cutter blades. Keep all
bystanders away from the mowing area.
5. Keep all shields and safety devices in place. If a
shield, safety device or decal is illegible or damaged,
repair or replace it before operation is commenced.
Also tighten any loose nuts, bolts and screws to ensure
machine is in safe operating condition.
6. Do not operate machine while wearing sandals, tennis
shoes, sneakers or shorts. Also, do not wear loose
fitting clothing which could get caught in moving
parts. Always wear long pants and substantial shoes.
Wearing safety glasses, safety shoes and a helmet is
advisable and required by some local ordinances and
insurance regulations.
7. Check interlock switches daily for proper operation
(Refer To Section in Traction Unit Operator ’s Manual
on Checking Interlock Switches). Do not rely entirely
on safety switches -shut off engine before getting off
seat. If a switch fails, replace it before operating the
machine. The interlock system is for your protection,
so do not bypass it. Replace all interlock switches
every two years. Interlock switches should be adjusted
so:
A. Engine cannot be started unless traction pedal is
released (neutral position) and PTO switch is
DISENGAGED (off position).
B. Engine stops if operator gets off seat when traction
pedal is depressed.
C. Engine stops if operator gets off seat when PTO
lever is ENGAGED (on position).
8. Fill fuel tank before starting the engine. Avoid spilling
any fuel. Since fuel is flammable, handle it carefully.
A. Use an approved fuel container.
B. Do not fill tank while engine is hot or running.
C. Do not smoke while handling gasoline.
D. Fill fuel tank outdoors and up to about one inch
from top of the tank, not the filler neck.
E. Wipe up any spilled gasoline.
While Operating
9. Do not run the engine in a confined area without
adequate ventilation. Exhaust fumes are hazardous and
could possibly be deadly.
10.Maximum seating capacity is one person. Never carry
passengers.
11. Sit on the seat when starting the engine and operating
the machine.
12.This product may exceed noise levels of 85 dB(A) at
the operator position. Ear protectors are recommended
for prolonged exposure to reduce the potential of
permanent hearing damage.
13.Before starting the engine:
A. Engage the parking brake.
B. Ensure traction pedal is in neutral and PTO is in
the OFF, disengaged position.
C. After engine is started, release parking brake and
keep foot off traction pedal. Machine must not
move. If movement is evident, the neutral return
mechanism is adjusted incorrectly; therefore, shut
engine off and adjust until machine does not move
when traction pedal is released.
14.Using the machine demands attention, and to prevent
loss of control:
A. Mow only in daylight or when there is good
artificial light.
B. Drive slowly and watch for holes or other hidden
hazards.
C. Do not drive close to a sand trap, ditch, creek or
other hazard.
3
D. Reduce speed when making sharp turns and when
turning on hillsides.
E. Avoid sudden starts and stops.
F. Before backing up, look to the rear and ensure no
one is behind the machine.
G. Watch out for traffic when near or crossing roads.
Always yield the right-of -way.
15.If engine stalls or machine loses headway and cannot
make it to the top of a slope, do not turn machine
around. Always back slowly straight down the slope.
16.DON’T TAKE AN INJURY RISK! When a person
or pet appears unexpectedly in or near the mowing
area, STOP MOWING. Careless operation, combined
with terrain angles, ricochets, or improperly positioned
guards can lead to thrown object injuries. Do not
resume mowing until area is cleared.
17.Never raise the cutting unit while the blades are
rotating.
18.If the cutting blades strike a solid object or the
machine vibrates abnormally, disengage PTO, move
throttle to SLOW, set parking brake and shut engine
off. Remove key from switch to prevent possibility of
accidental starting. Check cutting unit and traction unit
for damage and malfunctioning parts. Repair any
damage before restarting the engine and operating the
cutting unit. Be sure blades are in good condition and
blade bolts are tight.
19.Cut grass slopes carefully. Do not start, stop, or turn
suddenly.
20.Do not touch engine or muffler while engine is running
or soon after it is stopped. These areas couId be hot
enough to cause a burn.
21.Before getting off the seat:
24.Perform only those maintenance instructions described
in this manual. If major repairs are ever needed or
assistance is desired, contact an Authorized Toro
Distributor.
25.To reduce potential fire hazard, keep the engine free of
excessive grease, grass, leaves and accumulations of
dirt. Never wash a warm engine or any electrical parts
with water.
26.Be sure machine is in safe operating condition by
keeping nuts, bolts and screws tight. Check the blade
mounting bolts and nuts frequently to be sure they are
tightened to specification.
27.Make sure all hydraulic line connectors are tight, and
all hydraulic hoses and lines are in good condition
before applying pressure to the system.
28.Keep body and hands away from pin hole leaks in
hydraulic lines that eject high pressure hydraulic fluid.
Use cardboard or paper to find hydraulic leaks.
Hydraulic fluid escaping under pressure can penetrate
skin and cause injury. Fluid accidentally injected into
the skin must be surgically removed within a few
hours by a doctor familiar with this form of injury or
gangrene may result.
29.Before disconnecting or performing any work on the
hydraulic system, all pressure in system must be
relieved by stopping engine and lowering cutting unit
to the ground.
30.If the engine must be running to perform a
maintenance adjustment, keep hands, feet, clothing
and other parts of the body away from the cutting unit
blades and other moving parts.
31.Do not overspeed the engine by changing governor
settings. To be sure of safety and accuracy, have an
Authorized TORO Distributor check maximum engine
speed with a tachometer.
A. Move traction pedal to neutral position and remove
foot from pedal.
B. Set the parking brake and disengage the PTO.
C. Shut the engine off and remove the key from the
ignition switch. Wait for all movement to stop
before getting off the seat.
22.Lower the cutting unit to the ground and remove key
from ignition switch whenever machine is left
unattended.
Maintenance
23.Remove key from ignition switch to prevent accidental
starting of the engine when servicing, adjusting or
storing the machine.
32.Engine must be shut off before checking oil or adding
oil to the crankcase.
33.At the time of manufacture the cutting unit conformed
to safety standards in effect for riding mowers.
Therefore, to ensure optimum performance and safety,
always purchase genuine TORO replacement parts and
accessories to keep the Toro all TORO. NEVER USE
“WILL–FIT” REPLACEMENT PARTS AND
ACCESSORIES MADE BY OTHER
MANUFACTURERS. Look for the TORO logo to
ensure genuineness. Using unapproved replacement
parts and accessories could void the warranty of The
Toro Company.
