housing to access the air cleaner element (Figure 34).
2. Unhook the latch and remove the air
cleaner(Figure 34).
3. Remove the foam element and inspect. Clean and
replace as necessary.

Servicing the Engine Oil

Oil Type: Detergent oil (API service SG, SH, SJ, or
higher)
Crankcase Capacity: 1.6-1.8 qt (1.7-1.9 l) when the
filter is changed
Viscosity: See the table below.
Figure 35
Important: Use other than service class SG, SH, SJ,
or higher oil or extending oil change intervals longer
than recommended can cause engine damage.
Note: Synthetic oils meeting the listed classifications
may be used with oil changes performed at the
recommended intervals. However to allow piston rings
to properly seat, a new or rebuilt engine should be
operated for at least 50 hours using standard petroleum
based oil before switching to synthetic oil.
Checking the Engine Oil Level
Service Interval: Before each use or daily
Note: Check the oil when the engine is cold.
WARNING
Contact with hot surfaces may cause personal
injury.
Keep hands, feet, face, clothing and other body
parts away the muffler and other hot surfaces.
Important: Do not overfill the crankcase with oil
because damage to the engine may result. Do not
run engine with oil below the low mark because the
engine may be damaged.
1. Disengage the blade control switch (PTO), move the
motion control levers to the neutral locked position
and set the parking brake.
2. Make sure the engine is stopped, level, and is cool so
the oil has had time to drain into the sump.
3. To keep dirt, grass clippings, etc., out of the engine,
clean the area around the oil fill cap/dipstick before
removing it.
4. Remove the dipstick and wipe the oil off.
Note: Check the style of oil dipstick for the engine.
Dipsticks with threaded caps are used differently
when checking the oil level than dipsticks that are
seated by pushing them into place.
5. Reinsert the dipstick into the tube to check the oil
level:
• Threaded dipstick caps: rest the cap on the
tube. Turn it couterclockwise until the oil dipstick
drops down to the lowest point of the thread
leads. Do not screw the cap onto the tube.
• Unthreaded dipstick caps: reinsert the dipstick
and push firmly into place.
6. Remove the dipstick out and check the oil level.
The oil level should be up to, but not over, the
"FULL" or "F" mark on the dipstick
7. If the level is low, add oil of the proper type, up to the
"FULL" or "F" mark on the dipstick. Always check
the level with the dipstick before adding more oil.
Note: To prevent extensive engine wear or damage,
always maintain the proper oil level in the crankcase.
Never operate the engine with the oil level below the
"ADD" or "L" mark or above the "FULL" or "F"
mark on the dipstick.
8. Remove dipstick and check oil level. The level should
be between the "Full or F" and "Add or L" marks. If
