Before You Begin Servicing
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 element(s) removed. This may
allow foreign material to enter the
engine and damage it.
CAUTION
The maximum air intake restriction, in
terms of differential pressure
measurement, must not exceed 0.90 psi
(6.23 kPa; 635 mmAq). Clean or replace
the air cleaner element if the air intake
restriction exceeds the above
mentioned value.
