Installing the Foam and Paper Elements
Important To prevent engine damage, always operate
the engine with the complete foam and paper air cleaner
assembly installed.
1. Carefully slide the foam element onto the paper air
cleaner element (Fig. 34).
2. Slide the air cleaner assembly onto the long rod. Screw
the rubber nut finger-tight against the air cleaner
(Fig. 35).
Note: Make sure the rubber seal is flat against the air
cleaner base.
3. Install the air cleaner cover and knob (Fig. 33). Tighten
the knob snugly.
4. Close the hood.
Cutting Blade
To ensure a superior quality of cut, keep the blades sharp.
For convenient sharpening and replacement, you may want
to have extra blades.
Danger
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.
Inspecting the Blades
1. Remove the mower; refer to Removing the Mower,
page 30.
2. Inspect the cutting edges (Fig. 38). If the edges are not
sharp or have nicks, remove the blades and sharpen
them; refer to Sharpening the Blade(s), page 30.
3. Inspect the blades, especially the bent edges (Fig. 38). If
you notice any wear or damage in this area,
immediately install a new blade.
4. If the shear pins are broken, replace them immediately
(Fig. 38).
Important If the shear pins are broken, the mower belt
may be damaged. Inspect the belt; refer to Adjusting the
Blade Drive Belt, page 31.
