2
)—through the filter element from the inside

CAUTION
Wear protective equipment such as
approved safety glasses or face shields
and dust masks or respirators when
cleaning air filters with compressed air.
NOTICE
DO NOT use excessive air pressure or the paper air
filter element will become damaged and will need to
be replaced.

NEVER run the engine with the air cleaner removed or
without an element.
Checking Engine Oil (Daily)
1. When checking or adding oil, place the machine so
the engine is level.
2. Pull the engine oil dipstick (Figure 44) from its holder
and wipe it clean.
Figure 44. Checking Engine Oil Level
3. Reinsert the dipstick.
4. Pull out the dipstick and check the oil level. The oil
should be between the ‘min.’ mark and the ‘max.’ mark
(Figure 44) on the dipstick.
5. If the oil level is low, add the correct amount of engine
oil to bring it to a normal, safe level. See Table 6 for
recommended oil viscosity.
6. Allow enough time for any added oil to make its way
to the oil pan before rechecking the level.
