the
API (American Petroleum
Institute) service designations
MS,
MS/DG, MS/DM,

conditions. Pull
the
start rope with
a
fast, steady pull
to crank
the
engine.
Do not
jerk.
As the set
warms
up-,
. adjust
the
choke gradually
to its
fully open position.
Remote Control,
AC
Models:
If the
battery charge
condition is
too low to
crank
the
engine, theset can
be
started manually.
Set the
control
box
switch (located
inside
the

recommendations.
Recommended Fuel:
Use
clean, fresh, regular grade,
automotive gasoline.
Do not use
highly leaded
premium types.
For new
engines, most satisfactory
results
can be
obtained
by
using nonleaded gasoline.
For older engines that have previously used leaded
gasoline, heads must
be
taken
off and all
lead
deposits removed from engine before switching
to
nonleaded gasoline.
rQ^yyiQ^yj^
If
lead deposits
are not
removed from engine
t^-*^^^-^^
before switching from leaded
to
unleaded
gasoline, pre-ignition could occur causing severe damage
to the
engine.

APPLYING
LOAD
If practical, allow
set to
warm
up
before connecting
a
heavy
load.
Continuous generator overloading
may
cause high operating temperatures that
can
damage
the windings. Keep
the
load within nameplate rating.
BATTERY
CHARGING
The battery charge rate
is
controlled
by a
2-step
voltage regulator
and is not
adjustable.
INFREQUENT
SERVICE
If theset
is
used infrequently
(as in
standby service
for
commercial power) extended shut-down periods
can
result
in
difficult starting.
Run the set at
least
30
minutes every week
to
eliminate hard starting.
ELECTRIC
STARTING
