Blow compressed air from inside to the
outside of dry filter element. Do not exceed 100
psi (689 kPa) to prevent damage to the element.
Keep air hose nozzle at least one inch
(25 mm) from pleated paper, and move nozzle
up and down while rotating the filter element.
Inspect element when dust and dirt are
removed; refer to Inspecting Filter Element.
Wipe inside of air cleaner body with a damp cloth to
remove excess dust. Slide filter into air cleaner body
and secure it in place with wing nut and gasket.
Reinstall dust cup and baffle. Move thumb screw
behind air cleaner body and tighten it securely.
Place bright light inside filter.
Rotate filter slowly while checking for cleanliness,
ruptures, holes, and tears. Replace defective filter
element.
Check fin assembly, gasket, and screen for
damage. Replace filter if damage is evident.
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.
*.! 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 removedĊby loosening wing nuts at top of
screenĊto make cleaning easier.
Check oil level after each day's operation or each time
machine is used. Change oil after every 50 hours of
operation; change oil filter after first 50 hours and every
100 hours operation thereafter. However, change oil
more frequently when engine is operated in dusty or
sandy conditions. If possible, run engine just before
changing oil because warm oil flows better and carries
more contaminants than cold oil.
Position machine on a level surface.
Disengage hood latch and open the hood. Set
drain pan under the housing and in line with drain plug
(Fig. 42).
