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 12 VDC powered tool or equipment to the DC Terminals.
CAUTION: 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.
THE 12V DC IS FOR BATTERY CHARGING ONLY.

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 or NGKBPRGES but we recommend our OEM spark
plug. To ensure proper engine operation, the spark plug must be properly gapped and free of
deposits.
1. Remove the spark plug cap.
2. Clean any dirt from around the spark plug base.
3. Use a spark plug wrench to remove the spark plug.
4. 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.
5. Measure the plug gap with a feeler gauge.(Correct as necessary by carefully bending the side electrode.)
The gap should be : 0.70-0.80 mm (0.028-0.031in)
6. Check that the spark plug washer is in good condition.
7. After the spark plug is seated, tighten with a spark plug in by hand to prevent cross-threading.
8 . 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.

Inspection, Cleaning, and
Maintenance
WARNING! ALWAYS MAKE SURE THE ENGINE POWER SWITCH (2) IS IN ITS
“OFF” POSITION. DISCONNECT THE SPARK PLUG WIRE FROM THE ENGINE.
AND ALLOW SUFFICIENT TIME FOR THE ENGINE AND GENERATOR TO
COMPLETELY COOL BEFORE PERFORMING ANY INSPECTIONS,
MAINTENANCE, OR CLEANING.

Fuel Sediment Cup Cleaning
The sediment cup prevents dirt or water which may be in the fuel tank from entering the carburetor.
If the engine has not been run for a long time, the sediment cup should be cleaned.
1. Turn the fuel valve to the OFF position. Remove the sedement cup, and O-ring.
2. Clean the sediment cup, and O-ring, in nonflammable or high flash point solvent.
3. Reinstall O-ring, and sediment cup.
4. Turn the fuel valve ON and check for leaks.
