3. Inspect primary filter and discard if damaged. Do not
wash or reuse a damaged filter.
Cleaning Air Filter
A. Blow compressed air from inside to the outside of
dry filter element. Do not exceed 100 psi to prevent
damage to the element.
B. Keep air hose nozzle at least 2” from filter and
move nozzle up and down while rotating the filter
element. Inspect for holes and tears by looking
through the filter toward a bright light.
4. Inspect new filter for shipping damage. Check sealing
end of filter. Do not install a damaged filter.
5. Insert new filter properly into air cleaner body. Make
sure filter is sealed properly by applying pressure to
outer rim of filter when installing. Do not press on
flexible center of filter.
6. Reinstall cover and secure latch. Make sure cover is
positioned with TOP side up.
7. Reset indicator (Fig. 41) if showing red.
Cleaning the Radiator and
Screen
The screen and front of the radiator must be kept clean to
prevent the engine from overheating. Normally, check the
screen and front of radiator daily and, if necessary, clean
any debris off these parts. However, it will be necessary to
check and to clean the screen each quarter hour and radiator
checked every hour in extremely dusty and dirty
conditions.
Note: This situation may be particularly prevalent if the
rear discharge cutting unit is being used. The front of the
radiator can be cleaned thoroughly by blowing with
compressed air from the fan side of the radiator. Make sure
to clean out any debris that settles to the bottom of the
screen. The screen in front of radiator can be removed—by
loosening wing nuts at top of screen—to make cleaning
easier.
Changing Engine Oil And Filter
Check oil level after each day’s operation or each time
machine is used. Change oil and filter initially after first 50
hours of operation; change oil and filter after every 100
hours of operation thereafter. If possible, run engine just
before changing oil because warm oil flows better and
carries more contaminants than cold oil.
1. Position machine on a level surface.
2. Open the hood. Set drain pan under the oil pan and in
line with drain plug (Fig. 44).
