7.4 ENGINE AIR CLEANER

A. CLEANING AND/OR REPLACING AIR
CLEANER ELEMENT
For any air cleaner, the operating environment dictates the
air cleaner service periods. Service and clean the air filter
pre-cleaner after every 50 hours of operation. Replace
the air cleaner element and pre-cleaner after every 300
hours or yearly, whichever comes first. Refer to Engine
Operator's Manual.
- NOTE -
In extremely dusty conditions it may be necessary
to check the element once or twice daily to prevent
engine damage.
1. Lift up on the latch securing the air cleaner cover to
the air cleaner assembly. See Figure 7-5.
2. Remove and inspect the air filter. Replace as
recommended by the engine manufacturer. Refer to
Engine Operator's Manual.
3. Replace the air cleaner cover and secure.

7.5 DRIVE BELTS

All drive belts are spring-loaded and self-tensioning,
however after the first 2, 4, 8 and 10 hours of operation,
the belts should be checked for proper alignment and wear.
Thereafter, check the belts after every 40 hours of operation
or weekly, whichever occurs first.
If you experience frequent belt wear or breakage,
see your authorized Scag service center for belt
adjustment.

7.6 CUTTER BLADES

A. BLADE INSPECTION
1. Remove the spark plug wire before servicing the
blades.
2. Raise the mower deck to the highest position. Place
the lanyard pin in the highest cutting height position
to prevent the cutter deck from falling.
WARNING
Mower blades are sharp. Always wrap blades,
wear proper hand and eye protection when
working with cutter blades.
3. Check the cutter blades for straightness. If the cutter
blades appear bent, they will need to be replaced.
4. Check the cutter blades for wear. If any part of the
cutter blade is worn to 1/2 its original thickness,
replace the cutter blade.
WARNING
Do not attempt to straighten a bent blade, and
never weld a broken or cracked blade. Always
replace it with a new blade to assure safety.
5. If a blade cutting edge is dull or nicked, it should be
sharpened. Remove the blades for sharpening. See
"Blade Replacement."
