Ring Free Fuel Additive
q When  the  air vent  screw  is loosened,
gasoline vapor  will be released.  Gaso-
line is highly flammable, and its vapors
are  flammable  and  explosive. Refrain
from  smoking,   and  keep  away   from
open flames  and sparks  while loosen-
ing the air vent screw.
Gasoline is a precise blend of many different
substances,  each  chosen   to  give  certain
characteristics. Gasoline  blends have  been
changing in recent years in response to con-
cerns  about  pollution  and  resulting   emis-
sions regulations.  One of the  most obvious
changes  has  been the  elimination  of  lead
from most fuels.
As gasoline has changed, the amount of ad-
ditives  such as  aromatics  and  oxygenates
has  increased. These  additives  are impor-
tant for  the engines  in passenger  cars, but
they can have  detrimental effects in  marine
engines,  because of  increased  deposits in
the combustion chamber. When enough de-
posits  collect,  piston  rings  begin  sticking.
Performance  drops   and  engine   wear  in-
creases dramatically.
q This
product   emits   exhaust    gases
which contain carbon monoxide, a col-
orless, odorless gas which could cause
brain  damage or  death  when inhaled.
Symptoms  include  nausea, dizziness,
and drowsiness. Keep cockpit and cab-
in areas well ventilated. Avoid blocking
exhaust outlets.
1.
If there is  an air vent  screw on the  fuel
tank cap, loosen it 2 or 3 turns.
While many additives  available may reduce
deposits, Yamaha  recommends  the use  of
Ring  Free  Fuel  Additive,  available   from
your Yamaha dealer. Ring Free Fuel  Addi-
tive has repeatedly proven its ability to clean
combustion deposits from inside the engine,
notably the critical piston-ring-land area, and
fuel system components.  Follow product la-
beling for use instructions.

If there is a fuel joint on the motor, firmly
connect the  fuel line  to  the joint.  Then
