Cleaning the Engine Screen
Service Interval: Before each use or daily—Clean the engine

To ensure proper cooling, make sure the grass screen, cooling
fins, and other external surfaces of the engine are kept clean

Use a dry brush to clean grass and accumulated debris from
the air intake screen and around the engine.
Important:
To prevent contaminating the fuel system,
do not use water to clean the engine.

Mower Maintenance
Servicing the Cutting Blades
Maintain sharp blades throughout the cutting season because
sharp blades cut cleanly without tearing or shredding the grass
blades. Tearing and shredding turns grass brown at the edges,
which slows growth and increases the chance of disease.
Check the cutter blades daily for sharpness, and for any
wear or damage. File down any nicks and sharpen the
blades as necessary. If a blade is damaged or worn, replace
it immediately with a genuine Toro replacement blade. For
convenient sharpening and replacement, you may want to
keep extra blades on hand.
WARNING
A worn or damaged blade can break, and a piece
of the blade could be thrown into the operator's
or bystander's area, resulting in serious personal
injury or death.
• Inspect the blade periodically for wear or
damage.
• Replace a worn or damaged blade.
Before Inspecting or Servicing the
Blades
Park the machine on a level surface, disengage the blade
control switch, and move the motion control levers outward
to the park position. Stop the engine and remove the key.
Inspecting the Blades
Service Interval: Before each use or daily—Check the
cutting blades.
1. Inspect the cutting edges (Figure 41). If the edges
are not sharp or have nicks, remove and sharpen the
blades; refer to Sharpening the Blades.
2. Inspect the blades, especially the curved area (Figure
41). If you notice any damage, wear, or a slot forming
in this area (item 3 in Figure 41), immediately install
a new blade.
