2. Place the air cleaner cover latches in the unlocked
position, then remove the air cleaner cover (Figure 31).
3. Remove the wing nut from the paper lter element
(Figure 31).
4. Remove the paper lter element and foam lter
element from the air cleaner case (Figure 31).
5. Remove the foam lter element from the paper lter
element.
6. Inspect both filter elements, and replace them if
they are damaged. ALWAYS replace the paper lter
element at the scheduled interval (see Table 8).
7. To clean the paper lter element as shown in Figure 31,
tap the lter element several times on a hard surface
to remove dirt, or blow compressed air, not to exceed
30 psi (207 kPa, 2.1 kgf/cm²), through the lter element
from the inside out.
8. Clean the foam lter element in warm, soapy water,
rinse, and allow to dry thoroughly, or clean the lter in
non-ammable solvent and allow it to dry. Dip the lter
element in clean engine oil, then squeeze (but DO NOT
twist) out all excess oil.
9. Using a moist rag, wipe dirt from the inside of the air
cleaner body and cover. Be careful to prevent dirt
from entering the air chamber that leads to the fuel
injection system.
10. Place the foam lter element over the paper lter
element, and reinstall the assembled lter elements. Be
sure the packing is in place beneath the lter element
assembly. Tighten the wing nut securely.
11. Lock the air cleaner cover latch securely.
12. Repeat steps 2–11 for the remaining Honda engine.
NOTICE
NEVER try to brush off dirt; brushing will force dirt
into the bers. Replace the paper lter element if it is
excessively dirty.
NOTICE
The engine will smoke when started if too much oil is
left in the foam.
MAINTENANCE
Use Table 8 as a general maintenance guideline. For
more detailed engine maintenance instructions, refer to
the Honda engine owner’s manual.
CLEANUP
NEVER allow concrete to harden on the trowel. Wash any
concrete off the trowel with water immediately after use.
Be careful to not spray a hot engine or mufer. An old paint
brush or broom may help loosen any concrete that has
started to harden.
ENGINE AIR CLEANERS
The engine air cleaners are equipped with an outer,
foam lter element and an inner, paper lter element
(Figure 31). Remove the air cleaner cover and inspect
the lter elements. Clean or replace dirty lter elements.
ALWAYS replace damaged lter elements.
