2.12.2 SENSING LOW OIL PRESSURE
If the system senses low oil pressure during operation, the engine shuts
down.
2.12.3 RESTARTING
If trying to restart the engine within 10 seconds after it shuts down, the
engine may NOT start. The system needs five (5) to 10 seconds to reset.
If the engine is restarted after such a shutdown and the low oil pressure
has not been corrected, the engine will run for about 10 seconds as
described above and then stop.

2.13 CHARGING A BATTERY


 Storage batteries give off explosive hydrogen
gas while recharging. An explosive mixture will
remain around the battery for a long time after
it has been charged. The slightest spark can
ignite the hydrogen and cause an explosion. Such
an explosion can shatter the battery and cause
blindness or other serious injury.
Do not permit smoking, open flame, sparks or

any other source of heat around a battery. Wear
protective goggles, rubber apron and rubber
gloves when working around a battery. Battery
electrolyte fluid is an extremely caustic sulfuric
acid solution that can cause severe burns. If spill
occurs flush area with clear water immediately.
This generator has the capability of recharging a discharged 12 Volt
automotive or utility style storage battery. Do not use the unit to charge
any 6 Volt batteries. Do not use the unit to crank an engine having a
discharged battery.
This battery charger is a pulse type designed to provide a quality charge
current into the battery. The voltage measured at the outlet should be 8-12
VDC. This is normal and does not indicate a faulty charging system.
To recharge 12 Volt batteries, proceed as follows:
1. Check fluid level in all battery cells. If necessary, add ONLY distilled
water to cover separators in battery cells. Do not use tap water.
2. If the battery is equipped with vent caps, make sure they are installed
and are tight.
3. If necessary, clean battery terminals.
4. Connect battery charge cable connector plug to panel receptacle
identified by the words "12-VOLT D.C."
5. Connect battery charge cable clamp with red handle to the positive
(+) battery terminal.
6. Connect battery charge cable clamp with black handle to the
negative (-) battery terminal.
7. Start engine. Let the engine run while battery recharges. Engine idle
control switch must be in off position for battery charging.
8. When battery has charged, shut down engine.
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.
3.1 PERFORMING SCHEDULED

MAINTENANCE

It is important to perform service as specified in the Maintenance
Schedule for proper generator operation, and to ensure that the generator
complies with the applicable emission standards for the duration of its
useful life. Service and repairs may be performed by any capable person
or repair shop. Additionally, emissions critical maintenance must be
performed as scheduled in order for the Emissions Warranty to be valid.
Emissions critical maintenance consists of servicing the air filter and spark
plugs in accordance with the Maintenance Schedule.
3.2

MAINTENANCE SCHEDULE

Follow the calendar intervals. More frequent service is required when
operating in adverse conditions noted below.
Check Oil Level
Change Oil ‡
Check Valve Clearance
Service Air Filter
Replace Spark Plug
‡ Change oil after first 30 hours of operation then every season.
* Change oil and oil filter every month when operating under heavy load or in
high temperatures.
** Clean more often under dirty or dusty operating conditions. Replace air filter
parts if they cannot be adequately cleaned.
*** Check valve clearance and adjust if necessary after first 50 hours of
operation and every 100 hours thereafter.
