Think Safety First

Avoid unexpected starting of engine…

Always turn off the engine and disconnect the spark plug

moving whenever the engine is running or has the

potential to start.

Avoid burns…

Do not touch the engine, mufer, or other components,

which may increase in temperature during operation,

while the unit is running or shortly after it has been

running.

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 conned 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.

Avoid injury due to inferior parts…

Use only original equipment parts to ensure that

important 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 debris

that could be picked up and thrown by the powered

equipment.

Avoid modications…

Never alter or modify any part unless it is a factory

approved procedure.

Torque Specications

Inch Series bolts and Screws

(A) Grade 1 & 2

(B) Grade 5

(C) Grade 8

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 identied and

specied in the service manual.

These torque specications for the installation and

tightening of fasteners shall apply to all fasteners

which do not have a specic requirement identied

in the service manual. The following factors shall be

consid ered 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, 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 specic 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 per-

formed 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 & Steel Fasteners (Inch Series)

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.
