SAFETY
CAUTION
If the fuel filter / water separator
is positioned higher than the fuel
level in the fuel tank, water may
not drip out when the fuel
filter / water separator drain cock
is opened. If this happens, turn
the air vent screw on the top of
the fuel filter / water separator
2-3 turns counterclockwise.
Be sure to tighten the air vent
screw after the water has drained
out.
CAUTION
• When the engine is operated in
dusty conditions, clean the air
cleaner element more
frequently.
• NEVER operate the engine with
the air cleaner or element(s)
removed. This may allow
foreign material to enter the
engine and damage it.
CAUTION
Clean or replace the air cleaner
element if the air intake
restriction exceeds the value
listed in the Operation and
Service Manuals.
