Before generator set is put
in
operation, check all
components for mechanical security. If an abnormal
condition, defective part, or operating difficulty is
detected, repair or service as required. Thegenerator
set should be kept free of dust, dirt, and spilled oil or
fuel. Be su.re proper operating procedure is followed.

CRANKCASE
OIL
Use a heavy duty detergent oil that meets the API
(American Petroleum Institute) service designations
MS, MS/DG, SE or SE/CC. Oil should be labeled as
having passed the
MS
SequenceTests (also known as
the ASTMG-IV SequenceTests) and the MIL-L-2104B
Tests. Recommended SAE oil numbers for expected
ambient temperatures are as follows:
30"
F to
90"
F
0°F to 30°F SAE 1OW
Below 0°F
SA€ 30
SAE 5W (5W-30 if
5W is not available)
Do not use service
DS
oil.
Do
not mix brands nor
grades. Refer to
Maintenance
section for
recommended oil changes.
RECOMMENDED GASOLINE
Use clean, fresh
regular
grade, automotive gasoline.
For new engines, most satisfactory results are ob-
tained 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.
If
lead deposits are not removed from engine
before switching from leaded to nonleaded
gasoline, pre-ignition could occur causing severe damage to the
engine.
To
prevent hazardous gasoline spillage, never
fill the tank when the engine
is
running and
leave some fuel expansion space. Observe safety precautions when
handling gasoline.
INITIAL START
Check the engine to make sure
it
has been filled with
oil and fuel. Cylinderair housing door must be closed.
If engine fails to start at first attempt, rust inhibitor oil
used at the factory may have fouled the spark plugs-
STARTING
1.
Push
srart-slop
switch to start position.
2. Release the switch after enginestarts and reaches
3. Oil pressure gauge should read at least
20
psi
speed.
(pressure relief is not adjustable).'
If the unit control has a reset button, push it to reset
only after a shutdown resulting from oil pressure
failure occurs. Find the cause before restarting the
engine. On early sets, reset or temporarily switch to
manual to start after oil filter change.
Leave
elec
start-handcrank
switch at
ekc
start
position.
This avoids battery discharge.
Exception:
While
emergency hand-cranking, switch to manual start
position, then return switch to
elec
start
position after
starting. (Older models with manual start only.)
If a false start occurs with a starter motor equipped
set, make sure the centrifugal switch closes during
speed build-up.
Extremes in starting temperatures may require a
slight electric chokeadjustment. If engine fails to start
quickly, rest engine several seconds before
successive cranking attempts to allow choke to cool
and close.
STARTING SEQUENCE
The starting and stopping (Figure 4) sequenceshows
the manual, mechanical, and electrical events re-.
quired for satisfactory start, run, and stop cycles.
ELECTRIC CRANKING
1.
Turn ignition switch on.
2. Set hand choke as required by temperature.
3. Engage START switch.
4. Release START switch when engine starts.
5.
See that oil
pressure is at least
20
psi (not
adjustable)
.
6.
Readjust manual choke as engine warms up.
Do
not apply overvoltage to the starting

circuit at any time.
If
it becomes necessary to
use an additional source
of
power to start the set
-
use a
12
volt
battery connected in parallel.
