BATTERY
CHARGING
(Beein
Spec D)
The battery charge rate
is automatically controlled
by
a
solid-state
voltage regulator.
The high charge tate was
set
at the factory for
average
operating
conditions.
INFREQUENT SERYICE
If
the
unit is
used
infrequently,
extended shutdown
periods
can result
in
difficult
starting. Run
unit
at
least 30
minutes
cvery
week to elirninate
hard
startitrg.
HIGH TEMPERATURES
1. See
that nothing
obstfucts
air flow
to and ftom the
plant.
2,
Keep cooling
fins
clean. Air
housing should be
ptoperly
installed and
undamaged-
3.
Keep ignition timi[g
properly
adjusted.
LOW
TEMPERATURES
1.
Use
coftect
SAE

Partially
restrict cool
air flow,
but use care to
avoid
ovelheating,
OUT.OF.SERVICE
PROTECTION
Protect a
plant
that will be out-of-service for
more than
30 days
as
follows:
1. Run
the
plant
until thoroughly warm,
2. Turn
ofl
fuel
supply and run

4. Remove
each spark
plug.
Pour
1
oz. (two table-
spoons)
of rust
inhibitor (or
SAE #50
oil)
into each
cylinder. Crank
engine slowly
(by hand) several
times.
Install
spark plugs.
5. Service air cleaner.
