Check Air Filter, Dust Cup, & Burp Valve
The air cleaner body, air filter, dust cup, 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 dust cup seals completely
to the air cleaner body (Fig. 3).
3. Check burp valve and dust cup for damage.
4. Make sure air hoses connecting the air cleaner to the
engine and radiator are secured tightly and free of pos-
sible air leaks.
