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.
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 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.
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.

Oil Level |
The transaxle is a sealed system and does not require periodic checking. Check oil at the oil |
|
fi ll plug location only. Do not check the oil at the vent tube. Checking oil at the vent tube will |
|
only give you a false reading or no reading at all, since this is the oil expansion area. If the oil |
|
needs to be checked, the transaxle must be removed to check oil level and IT CAN BE ONLY |
|
CHECKED COLD. There is a fi ll plug located at the top of the transaxle. To check the level of |
|
the oil, remove the fi ll plug. Oil level should be 3/4” (1.9cm) from the top of the oil fi ll plug. |
Fluid Change |
The transaxle is factory fi lled and does not require regular oil changes. |

Torque Specifications |
Fastener Identification |
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.
2These 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.

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.
