To reduce the potential for injury or death, com-
ply with the following safety instructions.
Before Operating
1. Review and understand the contents of the Opera-
tor’sManualandOperatorTrainingDVD beforestarting
and operating the machine. Become familiar with the
controls and know how to stop the machine and engine
quickly. A replacement Operator’s Manual is available
on the Internet at www.Toro.com.
2. Keep all shields,safety devices and decals in place.
Ifashield,safetydeviceordecalisdefective,illegibleor
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 traction pedal is in
NEUTRAL, PTO switch is OFF (disengaged) andeither
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 fuel.
D. Fill fuel tank outdoors and only to the bottom of
the filler neck. Do not overfill fuel tank.
E. Replacefueltankandfuelcontainercapssecure-
ly after refueling machine.
F. If fuel is spilled, do notattempt to start theengine
butmovethemachineawayfromtheareaofthespill-
age. Wipe up any spilled fuel.

Groundsmaster 360 Page 1 -- 3 Safety
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 the traction pedal is in NEUTRAL and
the PTO switch is OFF (disengaged).
NOTE: If machine is on any type of slope, it may
move when parking brake is released.
C. With machine on a level surface after engine is
started,releaseparkingbrakeandkeepfootofftrac-
tion pedal. Machine must not move. If movement is
evident, the traction linkage may be adjusted incor-
rectly.Shutengine offandcheck tractionlinkagead-
justment. If necessary, adjust linkage until machine
does not move when traction pedal is in NEUTRAL.
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
whileengineisrunningorsoonafteritisstopped.These
areas could be hot enough to cause burns.
5. Before getting off the seat:
A. Ensure that traction pedal is in NEUTRAL.
B. Loweranddisengagecuttingdeckandwaitforall
movement to stop.
C. Set parking brake.
D. Stopengineandremovekeyfromignitionswitch.
6. Anytime the machine is parked (short or long term),
thecutting deckshouldbeloweredto theHOCpin.This
relieves pressure from the lift circuit and eliminates the
risk of the cutting deck accidentally lowering.
7. Donotparkonslopes unlesswheels arechockedor
blocked.

Then, stop engine, set parking brake and remove key
from the switch.
2. Make sure machine is in safeoperating condition by
routinely inspecting fasteners (nuts, bolts and screws)
to make sure they are tight.
3. Never store the machine or fuel container inside
wherethereisanopenflame,suchasnearawaterheat-
er or furnace.
4. Makesureallhydrauliclineconnectorsaretight,and
all hydraulic hoses and lines are in good condition be-
fore applying pressure to the hydraulic system.
5. Keepbodyandhandsawayfrompinholeleaksinhy-
drauliclinesthatejecthighpressurehydraulicfluid.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

Torque Specifications
Recommended fastener torque values are listed in the
followingtables.Forcriticalapplications,asdetermined
byToro,eithertherecommendedtorqueoratorquethat
is unique to the application is clearly identified and spe-
cified in this Service Manual.
These Torque Specifications for the installation and
tightening of fasteners shall apply toall fasteners which
donot havea specificrequirement identifiedin thisSer-
viceManual.Thefollowingfactorsshouldbeconsidered
when applying torque: cleanliness of the fastener, use
of a thread sealant (e.g. Loctite), degree of lubrication
on the fastener, presence of a prevailing torque feature
(e.g. Nylock nut), hardness of the surface underneath
thefastener’sheadorsimilarconditionwhichaffectsthe
installation.
Asnotedinthefollowingtables,torquevaluesshouldbe
reduced by 25% for lubricated fasteners to achieve
the similar stress as a dry fastener. Torque values may
also have to be reduced when the fastener is threaded
into aluminum or brass. The specific torque value
should be determined based on the aluminum or brass
material strength, fastener size, length of thread en-
gagement, etc.
The standard method of verifying torque shall be per-
formed by marking a line on the fastener (head or nut)
and mating part, then back off fastener 1/4 of a turn.

the lines match up.

Using a Torque Wrench with an Offset Wrench
Useofanoffsetwrench(e.g.crowfootwrench)willaffect
torquewrench calibrationdue tothe effectivechangeof
torquewrenchlength.Whenusingatorquewrenchwith
an offset wrench, multiply the listed torque recommen-
dation by the calculated torque conversion factor (Fig.
3) to determine proper tightening torque. Tightening
torque when using a torque wrench with an offset
wrench will be lower than the listed torque recommen-
dation.
Example: The measured effective length of the torque
wrench (distance from the center of the handle to the
center of the square drive) is 18”.
Themeasuredeffectivelengthofthetorquewrenchwith
the offset wrench installed (distance from the center of
the handle to the center of the offset wrench) is 19”.
The calculated torque conversion factor for this torque
wrenchwiththis offsetwrenchwould be18/19 =0.947.
If the listed torque recommendation for a fastener is
from 76 to 94 ft--lb, the proper torque when using this
torque wrench with an offset wrench would be from 72
to 89 ft--lb.
