2. If battery is equipped with vent caps, make sure they
are installed and are tight.
3. If necessary, clean battery terminals.

6. Connect battery charge cable clamp with bmack handle
to the negative (-) battery terminal (Figure 7).
7. Start engine. Let engine run while battery recharges.
8. 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] combined with high humidity), your generator
may experience icing of the carburetor and/or the
crankcase breather system.To reduce this problem_ you
need to perform the following:
I. Make sure generator has dean_ fresh fuel.
2. Open fuel valve (turn valve to open position).
3. Use SAE SWo30 oil (synthetic preferred, see engine
