Air Filter
Turbo-charged engines are especially demanding on air
î›™lter performance. The operator should be continually
aware of the condition of the air î›™lter system. Inspect
all components for damage, cracked hoses or loose
clamps. Replace the î›™lter every 100 service hours. The
air î›™lter is mounted on top of the engine sound shield
between the two conveyers. (Figure 5-15) A restriction
indicator is mounted on the side of the outlet that should
be checked often. If the red indicator is visible, the air
cleaner element must be replaced.

As the air î›™lter becomes more clogged, the air pressure
increases, causing the indicator to illuminate. When
this occurs, the air î›™lter must be cleaned or replaced as
follows:
Be sure to clean the inside of the air
cleaner body before replacing the air î›™lter element.
Be careful not to introduce any contaminants into the
engine intake tube.
1. Open clamps securing the cover on the î›™lter
housing, then remove the cover.
2. Remove the î›™lter cartridge.
3. Replace with the new î›™lter cartridge.
4. Reinstall cover and secure with the clamps.
5. Reset the î›™lter indicator by pressing button on top of
the indicator.
NEVER operate machine without air
î›™lter to prevent destruction of the engine.
Radiator Coolant
Check the radiator daily to ensure the radiator is full
and that no debris is present as this could block the
system and cause overheating. (Compressed air can
be used to remove any debris from the radiator.) You
can access the radiator surge tank î›™ll cap via the front
access door between the two conveyors.
When the engine is cold, the coolant level should cover
the radiator core. If low, î›™ll with a solution of 50 percent
water and 50 percent ethylene-glycol antifreeze. Flush
the radiator system every 500 service hours (see your
Engine Operator Manual for more information).
DO NOT remove the radiator surge
tank cap while the engine is still hot. The radiator is
under pressure and the hot water can cause serious
injury.
Avoid prolonged and repeated skin
contact with used antifreeze as contact can cause
skin disorders or injury. Wash thoroughly after any
contact.
ALWAYS wear eye protection when
using compressed air to prevent injury.
To check the radiator or add coolant:
1. Open the access door to access the radiator surge
tank cap. (Figure 5-16)
2. Remove the cap to check ONLY WHEN UNIT IS
COOL. Coolant level should be visible.
3. If coolant level is low, add coolant. DO NOT overî›™ll.
