Think Safety First
Avoid injury due to inferior parts...
Use only original equipment parts to ensure that import-
ant safety criteria are met.
Avoid injury to bystanders...
Always clear the area of bystanders before starting or
testing powered equipment.
Avoid injury due to projectiles...
Always clear the area of sticks, rocks, or any other de-
bris that could be picked up and thrown by the powered
equipment.
Avoid modications...
Never alter or modify any part unless it is a factory ap-
proved procedure.
Avoid unsafe operation...
Always test the safety interlock system after making
adjustments or repairs on the machine. Refer to the
Electrical section in this manual for more information.
Avoid unexpected starting of engine...
Always turn off the engine and disconnect the spark plug
wire(s) before cleaning, adjusting, or repair.
Avoid lacerations and amputations...
Stay clear of all moving parts whenever the engine is
running. Treat all normally moving parts as if they were
moving whenever the engine is running or has the po-
tential to start.
Avoid burns...
Do not touch the engine, mufer, or other components
which may increase in temperature during operation,
while the unit is running or shortly after it has been run-
ning.
Avoid res and explosions...
Avoid spilling fuel and never smoke while working with
any type of fuel or lubricant. Wipe up any spilled fuel
or oil immediately. Never remove the fuel cap or add
fuel when the engine is running. Always use approved,
labeled containers for storing or transporting fuel and
lubricants.
Avoid asphyxiation...
Never operate an engine in a conned area without
proper ventilation.
Avoid injury from batteries...
Battery acid is poisonous and can cause burns. Avoid
contact with skin, eyes, and clothing. Battery gases can
explode. Keep cigarettes, sparks, and ames away from
the battery.

Torque Specifications
Recommended fastener torque values are listed in the
following tables. For critical applications, as
determined by Toro, either the recommended torque or
a torque that is unique to the application is clearly
identified and specified in the service manual.
These torque specifications for the installation and
tightening of fasteners shall apply to all fasteners which
do not have a specific requirement identified in the
service manual. The following factors shall be
considered when applying torque: cleanliness of the
fastener, use of a thread sealant (Loctite), degree of
lubrication on the fastener, presence of a prevailing
torque feature, hardness of the surface underneath of
the fastener’s head, or similar condition which affects
the installation.
As noted in the following tables, torque values should
be 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 engagement, etc.
The standard method of verifying torque shall be
performed by marking a line on the fastener (head or
nut) and mating part, then back off fastener 1/4 of a
turn. Measure the torque required to tighten the
fastener until the lines match up.

Standard Torque for Dry, Zinc Plated, and Steel Fasteners (Inch Series)
Note: Reduce torque values listed in the table above
by 25% for lubricated fasteners. Lubricated fasteners
are defined as threads coated with a lubricant such as
oil, graphite, or thread sealant such as Loctite.
Note: Torque values may have to be reduced when
installing fasteners into threaded aluminum or brass.
The specific torque value should be determined based
on the fastener size, the aluminum or base material
strength, length of thread engagement, etc.
Note: The nominal torque values listed above for
Grade 5 and 8 fasteners are based on 75% of the
minimum proof load specified in SAE J429. The
tolerance is approximately ± 10% of the nominal
torque value. Thin height nuts include jam nuts.
