• Start engine. Let the engine run while battery recharges.
• When battery has charged, shut down engine
NOTE: Use an automotive hydrometer to test battery
state of charge and condition. Follow the hydrometer
manufacturer's instructions carefully. Generally, a battery is
considered to be at 100% state of charge when specific
gravity of its fluid (as measured by hydrometer) is 1.260 or
higher.
COLD WEATHER

OPERATION

Under certain weather conditions (temperatures below
40°F [4°C] and a high dew point), your generator may
experience icing of the carburetor and/or the crankcase
breather system.
Build a structure that will enclose three sides and the top
of the generator:
• Make sure entire muffler-side of generator is exposed.
Note that your generator may appear different from that
shown in Figure 9.

• Ensure a minimum of two feet clearance between open
side of box and nearest object.
• Face exposed end away from wind and elements.
• Enclosure should hold enough heat created by the
generator to prevent problems.
CAUTION
enclose generator any more than shown. Remove
generator from shelter when temperature is above
40°F [4°C].
How to Use the Battery Charger
Use battery float charger jack to keep the starting battery
charged and ready for use. Battery charging should be done
in a dry location, such as inside a garage.
• Plug the charger into the unit's "Battery Float Charger"
jack, which is located on the starter switch (Figure 10).
Plug battery charger into a 120 Volt AC wall receptacle.
Figure 10 — Battery Charger Jack
• Unplug the charger from the unit and the wall outlet
when generator is being started and while it is in
operation.
• Keep this charger plugged in when generator is not in
use to prolong battery life.The charger has a built in
float equalizer and will not overcharge the battery, even
when plugged in for an extended period of time.
