IMPORTANT:
Do not use galvanized lines,
fittings
or
fuel
tanks.
Carefully
clean all
fuel
system components before
putting
the engine
into
operation. Any
dirt
or contamination
may
cause
major
damage
to the
fuel
injection
system.
Starting
with
Spec
S, a new
fuel
filtration
system accom-
modates
both
primary
and secondary
fuel
filters
on
a common
mounting
casting
which
is bolted to a newly designed oil
fill
tube. The engine cannot be run
with
either
filter
loose
or
missing, thus ensuring proper
filtration
at all times.
BATTERY
Mount
the batteries on a
wood
or metal
rade
near
the engine.
Air
circulation
around the battery is essential. Use #2
batteiy
cables
of the proper length to
limit
voltage drop.
Coat connections on the battery
with
vaseline to prevent
corrosion.
BATTERY
CONNECTIONS
Batteries for
engines
equipped
with
optional
flywheel
alter-
nators must be negatively grounded. A 20 AMP fuse pro-
tects
the
rectifier
should the battery be connected
with
reverse
polarity.
On early models
without
fuse, destruction
of
the
rectifier
will
result. If battery positive (+) must be
grounded to
agree
with
related equipment,
reverse
recti-
fier
connections
(Fig.
1-4).
Connect the remaining battery cable to the larger terminal
on
the starting motor solenoid
(Fig.
1-3).
OIL
DRAIN
EXTENSION
For
service convenience,
install
an oil drain extension
made
from
standard pipe and
fittings,
in the 1/2" pipe
tapped
oil
base
drain hole.
