Toroforcompliancewithnationalandinternationalstan-
dards as specified in the Operator’s Manual. Although
hazard control and accident prevention partiallyare de-
pendent upon the design and configuration of the ma-
chine, these factors are also dependent upon the
awareness, concern and proper training of the person-
nel involved in the operation, transport, maintenance
and storage of the machine. Improper use or mainte-
nance of the machine can result in injury or death.

Maintenance and Service
1. Before servicing or making adjustments to the ma-
chine, stop the engine, remove key from switch to pre-
vent accidental starting of the engine.
2. Be sure entire machine is in good operating condi-
tion. Keep all nuts, bolts, screws and hydraulic fittings
tight.
3. Make sure all hydraulic line connectors are tight,and
all hydraulic hoses and lines are in good condition be-
fore applying pressure to the system.
4. Keep body and hands away from pin hole leaks or
nozzles that eject hydraulic fluid under high pressure.
Use paper or cardboard, not hands, to search for leaks.
Hydraulic fluid escaping under pressure can have suffi-
cient force to penetrate skin and do serious damage. If
fluidisejectedintotheskinitmustbesurgicallyremoved
within a few hours by a doctor familiar with this form of
injury or gangrene may result.
5. Before disconnecting or performing any work on the
hydraulic system, all pressure in system must be re-
lievedbystoppingengineandloweringcuttingunitsand

free of excessive grease, grass, leaves and accumula-
tion of dirt. Never wash a warm engine or electrical con-
nections with water.
7. Check allfuel lines for tightness and wear on aregu-
lar basis. Tighten or repair fuel lines as needed.
8. If the engine must be running to perform a mainte-
nance adjustment, keep hands, feet, clothing and any
other parts of the body away from the cutting units, at-
tachmentsandanymoving parts. Keepeveryoneaway.
9. Do not overspeed the engine by changing governor
settings.Toassuresafetyandaccuracy,haveanAutho-
rized Toro Distributor check maximum engine speed
with a tachometer. Maximum governed engine speed
should be 2850 + 50 RPM.

Torque Specifications
Recommended fastener torque values are listed in the
following tables. For critical applications,asdetermined
byToro,eithertherecommendedtorqueoratorquethat
is unique to the application is clearly identified and spe-
cified in this Service Manual.
Thesetorquespecificationsfortheinstallationandtight-
ening of fasteners shall apply to all fasteners which do
nothaveaspecific requirementidentifiedin thisService
Manual.The followingfactorsshallbe consideredwhen
applying torque: cleanliness of the fastener, use of a
threadsealant(e.g.Loctite),degreeoflubricationonthe
fastener, presence of a prevailing torque feature, hard-
ness of the surface underneath the fastener’s head or
similar condition which affects the 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.

Using a Torque Wrench with an Offset Wrench
Useofanoffsetwrench(e.g.crowfootwrench)willaffect
torque wrench calibration due to theeffective change of
torque wrench length.Whenusingatorquewrench with
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
wrenchwiththisoffsetwrenchwouldbe18/ 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.
