Maintenance Safety

•
Disconnect the spark-plug wire from the spark plug
before performing any maintenance procedure.
•
Wear gloves and eye protection when servicing
the machine.
•
The blade is sharp; contacting the blade can result
in serious personal injury. Wear gloves when
servicing the blade. Do not repair or alter the
blade(s).
•
Never tamper with safety devices. Check their
proper operation regularly.
•
Tipping the machine may cause the fuel to leak.
Fuel is flammable and explosive, and can cause
personal injury. Run the engine dry or remove the
fuel with a hand pump; never siphon the fuel.
•
To ensure optimum performance of the machine,
use only genuine Toro replacement parts and
accessories. Replacement parts and accessories
made by other manufacturers could be dangerous,
and such use could void the product warranty.
Maintenance Procedure
• Check the engine-oil level and add oil as needed.
• Ensure that the blade stops within 3 seconds after releasing the blade-control bar.
• Check the blade-brake-clutch operation.
• Clean grass clippings and dirt from under the machine.
• Service the air filter; service it more frequently in dusty operating conditions.
• Clean the blade-brake-clutch shield.
• Replace the air filter; replace it more frequently in dusty operating conditions.
• Change the engine oil (if desired).
• Replace the blade or have it sharpened (more frequently if the edge dulls quickly).
• Clean the engine by removing dirt and debris from its top and sides; clean it more
frequently in dusty operating conditions.
• Empty the fuel tank before repairs as directed and before yearly storage.

Preparing for Maintenance

1. Shut off the engine and wait for all moving parts
to stop.
2. Disconnect the spark-plug wire from the spark
plug (Figure 29).
3. After performing the maintenance procedure(s),
connect the spark-plug wire to the spark plug.
Important:
Before tipping the machine to
change the oil or replace the blade, allow the
fuel tank to run dry through normal usage. If
you must tip the machine prior to running
out of fuel, use a hand fuel pump to remove
the fuel. Always tip the machine onto its
side, with the dipstick down.
