Servicing Air Cleaner - Yamaha EF12000DE Owner's Manual

SERVICING AIR CLEANER

A dirty air cleaner element will cause
starting difficulty, power loss, engine mal-
functions, and shorten engine life
extremely.
Always keep the air cleaner element
clean. Replace the air cleaner element set
more often in dusty environments.
The air cleaner paper inner element and
urethane foam outer element can be
removed after removing knob and air
cleaner cover. When installing, set the
paper element and urethane foam on the
air cleaner base. Check that the grommet
is in position, and then install the cover
with knob tightened securely.
I
Urethane Foam cleaning
Wash and clean the urethane foam in
kerosene. Saturate in a mixture of 3
parts kerosene and 1 part engine oil,
and then squeeze to remove excess oil.
Clean or replace the urethane foam ele-
ment every 50 hours. (more often in
dusty environments)
I
Paper element
Clean by tapping gently to remove dirt
and blow off dust. Never use oil.
Clean or replace the paper element
every 50 hours of operation, and
replace element set every 200 hours or
once a year.
