Owner's Manual
Operation (cont'd)
Powering 12 Volt DC tools and Equipment:
1. Prior to powering tools and equipment, make sure the generator's rated voltage, and amperage
capacity (12V DC) is adequate to supply all electrical loads that the unit will power. If powering
exceeds the generator's capacity, it may be necessary to group one or more of the tools and/or
equipment for connection to a separate generator.
2. Connect the power cord of a 12V DC powered tool or equipment to the DC Terminals.
_ AUTION: MAKE SURE TO CONNECT THE POSiTiVE (+) LEAD OF THE
POWER CORD TO THE POSiTiVE (+) TERMINAL ON THE GENERATOR,
AND CONNECT THE NEGATIVE (-) LEAD OF THE POWER CORD TO THE
NEGATIVE (-) TERMINAL ON THE GENERATOR.
3. Start and run the engine as described above
4. When finished using the generator, turn the engine power switch to its "OFF" position. Turn
the fuel valve to its "OFF" position.
5. Disconnect the electrical powered tools' power cord from the generator's DC terminals.

Operation (cont'd)
Spark Plug Service
In order to service the spark plug, you will need a spark plug wrench (commercially available).
Recommended spark plugs: NHSP LD F7TC. To ensure proper engine operation, the spark plug
must be properly gapped and free of deposits.
1. Remove the spark plug cap.
2. Use a spark plug wrench to remove the spark plug.
3. Visually inspect the spark plug. Discard it if the insulator is cracked or chipped. Clean the spark
plug with a wire brush if it is to be reused.
4. Measure the plug gap with a feeler gauge.
5. Check that the spark plug washer is in good condition.
6. After the spark plug is seated, tighten with a spark plug in by hand to prevent cross-threading.
7, After the spark plug is seated, tighten with a spark plug wrench to compress the washer.
NOTE: THE SPARK PLUG MUST BE SECURELY TIGHTENED. AN IMPROPERLY
TIGHTENED SPARK PLUG CAN BECOME VERY HOT AND COULD DAMAGE THE
ENGINE. NEVER USE SPARK PLUGS WHICH HAVE AN IMPROPER HEAT RANGE.
USE ONLY RECOMMENDED SPARK PLUS OR EQUIVALENT.
6. After the engine and generator have completely cooled, store the generator in a safe, clean, dry
location (if not already installed in one).
NOTE: The 12V DC is only used for charging batteries.
