OPERATION
INITIAL START
Check the engine to make sure it has been filled with
oil and fuel. If engine fails to start at first attempt,
inhibitor oil used at the factory may have fouled the
spark plugs — remove, clean in a suitable solvent, dry
thoroughly and install. Heavy exhaust smoke when
the engine is first started is normal and is caused by
the inhibitor oil.
Recommended Fuel: For new engines, most satisfac¬
tory results are obtained by using nonleaded gas¬
oline. For older engines that have previously used
leaded gasoline, heads must betaken off and all lead
deposits removed from engine before switching to
nonleaded gasoline. Do not use highly leaded
premium fuels.
! Never fill the tank when the engine is running
and leave some fuel expansion space to
prevent possibility of explosion.
Crankcase Oil: Use a good quality, heavy duty oil with
the API (American Petroleum Institute) designation
SE or S^CC (gasoline operation only). If this oil is
not available, SD or SD/CC designated oil can be
used. For gaseous fuel operation, use an ashless or
low-ash detergent oil specifically made for gaseous
fueled engines.
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.
ELECTRIC STARTING
Remote Control, AC Set: Push thesfarf-sfop switch to
its start position. Release the switch as soon as the set
starts.
Oil consumption may be higher with a multigrade oil
than with a single-grade oil if both oils have com,-
parable viscosities at 210° F (99°C). Therefore, single
grade oils are generally more desirable unless an¬
ticipating a wide range of temperatures. Use the
proper grade oil for the expected conditions (Chart
1 ) .
MANUAL STARTING
Portable Type Set: Close the manual choke about
three-quarters or as necessary according to
temperature conditions. Pull the start rope with a fast,
steady pull to crank the engine. Do not jerk. Asthe set
warms up, adjust the choke gradually to its fully open
position.
CHART 1. OIL RECOMMENDATIONS ACCORDING TO
AIR TEMPERATURE
Above 32°F (0°C).SAE 30
0°F to 32°F (0°C).SAE 10W-40 or 5W-30
Below 0°F (-18°C) .SAE 5W-30
APPLYING LOAD
Allow set to warm up before connecting a heavy load
and keep the load within nameplate rating. Con¬
tinuous generator overloading may cause high
operating temperatures that can damage the win¬
dings.
BATTERY CHARGING
The battery charge rate is controlled by a two-step
charge regulator. This regulator is preset and is not
adjustable.
Do not mix brands or grades. Refer to Maintenance
section for recommended oil changes.
