3. Inspect primary filter and discard if damaged. Do
not wash or reuse a damaged filter.
Cleaning the Air Filter
A. Blow compressed air from the inside to the
outside of a dry filter element. To prevent
damage to the element, don't exceed 689
kPa.
B. Keep the air hose nozzle at least 5cm from
the filter and move the nozzle up and down
while turning the filter element. Inspect for
holes and tears by looking through the filter
toward a bright light.
4. Inspect the new filter for shipping damage.
Check the sealing end of the filter. Don't install a
damaged filter.
5. Take care to insert the new filter correctly into
the air cleaner body. Make sure the filter is sealed
properly by applying pressure to the outer rim of
the filter when installing. Don't press on the
flexible center of the filter.
6. Reinstall the cover and secure the latch. Make
sure the cover is positioned with the TOP side up.
7. Reset the indicator (Fig. 22) if it shows red.
Cleaning the Radiator and
Screen
The screen and front of the radiator must be kept clean
to prevent the engine from overheating. Check the
screen and front of the radiator daily and, if necessary,
clean any debris from these parts. However, in
extremely dusty and dirty conditions, check and clean
the screen each quarter hour and check the radiator
every hour.
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 the
radiator can be removed—by loosening wing nuts at
the top of screen—to make cleaning easier.

Changing Engine Oil and Filter

Check the oil level after each day's operation or each
time the machine is used. Change the oil after every
50 hours of operation; change the oil filter after first
50 hours and every 100 hours operation thereafter. If
possible, run the engine just before changing oil
because warm oil flows better and carries more
contaminants than cold oil.
1. Position the machine on a level surface.
2. Open the hood. Set drain pan under the oil pan
and in line with drain plug (Fig. 25).
