Check Air Filter, Filter Cover, & Burp Valve
The air cleaner body, air filter, filter cover, and burp valve
should be checked daily, prior to operation.
IMPORTANT: Any leaks in the air cleaner system
will cause serious engine damage. Make sure that
all air cleaner components are in good condition
and are properly secured during operation.
1. Park machine on a level surface, lower cutting units,
stop engine, engage parking brake, and remove key
from the ignition switch. Unlatch and raise hood.
2. Check air cleaner body for damage that could cause
possible air leaks. Make sure filter cover seals com-
pletely to the air cleaner body (Fig. 3).
3. Check burp (actuator) valve and filter cover for dam-
age.
4. Make sure air hoses connecting the air cleaner to the
engine and radiator are secured tightly and free of pos-
sible air leaks.
