MAINTENANCE AND LUBRICATION 8
8.11 AIR CLEANER ________________________________________________________
Service Air Filter
Check the service indicator (1) each day. If the red band become visible
in the window (2), replace the filter elements.
Do not remove the elements to inspect or clean. Removal of the filter is
not necessary and increases the risk of dust and other particles
entering the engine.
When service is needed, first clean the outside of the filter housing (4),
then remove the filter element carefully.
Clean the inside of the filter housing. Make sure dust and other particles
do not get into the engine inlet hose.
Inspect the new element. Do not use a damaged element and never
use an incorrect element.
Assemble the filter element. Make sure the element seats correctly. Press the button (3) to set the service
indicator.
Assemble the cap (5) to the filter housing (4). Make sure the cap seals around the filter housing. The dust valve
(6) on the cap must be at the bottom of the filter. Fasten the cap with the two clips.
Check the air filter hose for wear or damage. Make sure the hose clamps are tight and hold the hose in position.
8.12 ENGINE EXHAUST ____________________________________________________
If the exhaust note or color changes, stop the engine immediately. Identify the problem and have the system
repaired.
Torque all exhaust manifold hardware equally. Tighten or replace the exhaust clamps.
WARNING
Fuel and its vapors are extremely flammable and explosive.
Fire or explosion can cause severe burns or death.
CAUTION
Never start and run the engine with the air cleaner assembly or the air filter removed.
NOTICE
Do not use pressurized air or solvents to clean the filter. Pressurized air can damage the filter and
solvents will dissolve the filter.
See the Maintenance Schedule for service requirements.
WARNING
The exhaust fumes contain carbon monoxide. The Carbon Monoxide in exhaust fumes can increase to
dangerous levels if the exhaust is damaged or you operate in closed spaces. Inspect the complete-
exhaust system every month and replace damaged components immediately.
NEVER operate the engine without enough ventilation.
The temperature of the exhaust components can be more than 300° F (149° C). To prevent the burns,
do not touch a hot exhaust system.
