can be made from the operator’s position.
Maintenance and storage
Keep all nuts, bolts and screws tight to be sure the
equipment is in safe working condition.
Do not use pressure clean equipment on machine.
Never store the equipment with gasoline in the tank
and inside a building where fumes can reach an open
flame or spark.
Allow the engine to cool before storing in any
enclosure.
To reduce the fire hazard, keep the engine, silencer,
battery compartment and gasoline storage are free of
grass, leaves, or excessive grease.
Check the grass catcher frequently and replace if worn
or deteriorated.
Replace worn or damaged parts for safety.
Replace faulty silencers.
If the fuel tank has to be drained, do this out–doors.
Do not change the engine governor settings or
overspeed the engine. Operating an engine at
excessive speed can increase the hazard of personal
injury.

On multibladed or multicylinder lawn mowers, take
care as rotating one blade or cylinder may cause others to rotate.
When lawn mower is to be parked, stored or left
unattended lower the cutting means unless a positive mechanical lock is provided.
Be careful during adjustment of the lawn mower to
prevent entrapment of the fingers between moving blades and fixed parts of the lawn mower.
To ensure the best performance and safety,
purchase only genuine Toro replacement parts and accessories. Do not use “will fit” parts and
accessories; they may cause a safety hazard.

Gasoline and Oil
Recommended Gasoline
Use Unleaded Regular Gasoline suitable for automotive use (85 pump octane minimum). Leaded regular gasoline may be used if unleaded regular is not available.
Important Never use methanol, gasoline containing
methanol, or gasohol containing more than 10% ethanol because the fuel system could be damaged. Do not mix oil with gasoline.
Danger
In certain conditions, gasoline is extremely flammable and highly explosive. A fire or explosion from gasoline can burn you and others and can damage property.
Fill the fuel tank outdoors, in an open area,
when the engine is cold. Wipe up any gasoline that spills.
Never fill the fuel tank inside an enclosed
trailer.
Do not fill the fuel tank completely full. Add
gasoline to the fuel tank until the level is 1/4 to 1/2 in. (6 to 13 mm) below the bottom of the filler neck. This empty space in the tank allows gasoline to expand.
Never smoke when handling gasoline, and stay
away from an open flame or where gasoline fumes may be ignited by a spark.
Store gasoline in an approved container and
keep it out of the reach of children. Never buy more than a 30-day supply of gasoline.
Always place gasoline containers on the ground
away from your vehicle before filling.
Do not fill gasoline containers inside a vehicle
or on a truck or trailer bed because interior carpets or plastic truck bed liners may insulate the container and slow the loss of any static charge.
When practical, remove gas–powered
equipment from the truck or trailer and refuel the equipment with its wheels on the ground.
If this is not possible, then refuel such
equipment on a truck or trailer from a portable container, rather than from a gasoline dispenser nozzle.
If a gasoline dispenser nozzle must be used,
keep the nozzle in contact with the rim of the fuel tank or container opening at all times until fueling is complete.
Warning
Gasoline is harmful or fatal if swallowed. Long–term exposure to vapors can cause serious injury and illness.
Avoid prolonged breathing of vapors.
Keep face away from nozzle and gas tank or
conditioner opening.
Keep gas away from eyes and skin.
Using Stabilizer/Conditioner
Use a fuel stabilizer/conditioner in the machine to provide the following benefits:
Keeps gasoline fresh during storage of 90 days or less.
For longer storage it is recommended that the fuel tank be drained.
Cleans the engine while it runs
Eliminates gum-like varnish buildup in the fuel
system, which causes hard starting
Important Do not use fuel additives containing
methanol or ethanol. Add the correct amount of gas stabilizer/conditioner to the
gas. Note: A fuel stabilizer/conditioner is most effective when
mixed with fresh gasoline. To minimize the chance of varnish deposits in the fuel system, use fuel stabilizer at all times.
Filling the Fuel Tank
1. Shut the engine off and set the parking brake.
2. Clean around fuel tank cap and remove the cap. Add
unleaded regular gasoline to fuel tank, until the level is 1/4 to 1/2 inch (6 to 13 mm) below the bottom of the filler neck. This space in the tank allows gasoline to expand. Do not fill the fuel tank completely full.
3. Install fuel tank cap securely. Wipe up any gasoline
that may have spilled.
Check Engine Oil Level
Before you start the engine and use the machine, check the oil level in the engine crankcase; refer to Checking the Engine Oil Level, page 22.
