Cleaning the Foam and Paper Elements
Foam Element:
1. Wash the foam element in liquid soap and warm water.
When the element is clean, rinse it thoroughly.
2. Dry the element by squeezing it in a clean cloth. Do
not oil the element.
Important: Replace the foam element if it is torn
or worn.
3. Install the foam element on a clean paper element.
Paper Element:
1. Tap the paper element on a solid flat surface and blow
it out from the inside with compressed air to remove
dust and dirt.
2. Inspect the element for tears, an oily film, and damage
to the rubber seal.
Important: Do not clean the paper element
with pressurized air or liquids, such as solvents,
gasoline, or kerosene. Replace the paper element
if it is damaged or cannot be cleaned thoroughly.
3. Clean the inside of the air cleaner cover of all dirt, dust,
and debris.
Installing the Foam and Paper Elements

the engine with the complete foam and paper air cleaner
assembly installed.

Servicing the Engine Oil

Oil Type: Detergent oil (API service SF, SG, SH, SJ, or higher)
Crankcase Capacity: 34 ounces (1.0 l) when you do not change
the filter; 36 ounces (1.05 l) when you change the filter.
Viscosity: See the table below.
Checking the Oil Level
1. Park the machine on a level surface.
2. Disengage the blade control (PTO).
3. Stop the engine, wait for all moving parts to stop, and
remove the key before leaving the operating position.
4. Clean around the oil dipstick (Figure 30) so that dirt
cannot fall into the fill hole and damage the engine.
1. Oil dipstick/fill hole
5. Unscrew the oil dipstick and wipe the end clean.
6. Screw the oil dipstick fully onto the fill hole.
7. Unscrew the dipstick again and look at the end. If the
oil level is low, slowly pour only enough oil into the fill
hole to raise the level to the Full mark on the dipstick.
