CLEANER SERVICE
KT engines have tear drop, square, or round air
cleaners with dry type filter elements. Elements
should be checked every 50 operating hours and
replaced when dirty. Check and replace more often
under extremely dirty, dusty conditions.
Replace
with a genuine Kohler element. Carefully
handle element -do not use if sealing surfaces are
damaged.
Some models are equipped with Precleaners, which
should be washed and oiled every 25 hours-see
Section 3 for details, and for proper disassembly
and reassembly procedures of air cleaners.

COOLING SYSTEM SERVICE
Air is drawn into the cooling shrouds by fins on the
flywheel. The air intake screen and cooling fins on
the cylinder heads and barrels must be kept clean
and unobstructed at all times.
CAUTION:
Do not operate engine with blower
housing or cooling shrouds removed.
They direct air flow past cooling fins
and removal results in improper air
circulation, overheating and engine
damage.
External surfaces (see Figure 1-2), must be kept
clean, free of oil and dirt accumulation. Dirty
external surfaces result in poor cooling efficiency.
