SAFETY INFORMATION
General Information
This symbol means WARNING or
PERSONAL SAFETY INSTRUCTION
- read the instruction because it has to
do with your safety. Failure to comply
with the instruction may result in
personal injury or even death.
This manual is intended as a service and repair
manual only. The safety instructions provided herein
are for troubleshooting, service, and repair of the
LX Series Riding Lawn Tractor.
Think Safety First
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
potential to start.
The riding mower and attachment operator's manual
contain safety information and operating tips for safe
operating practices. Operator's manuals are available
through your Toro parts source or:
The Toro Company
Publications Department
8111 Lyndale Avenue South
Bloomington, MN 55420
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 flames away
from the battery.
Avoid injury due to inferior parts...
Use only original equipment parts to ensure that
important safety criteria are met.
1
Avoid burns...
Do not touch the engine, muffler, or other components
which may increase in temperature during operation,
while the unit is running or shortly after it has been
running.
Avoid fires 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 confined area without
proper ventilation.
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 modifications...
Never alter or modify any part unless it is a factory
approved 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.

SPECIFICATIONS
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.

Figure 1
(C) Grade 8
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.
