ELECTRICAL
GENERATOR CAPACITY
Make sure the generator can supply enough continuous
(running) and surge (starting) watts for the items you will
power at the same time. Follow these simple steps.
1. Select the items you will power at the same time.
2. Total the continuous (running) watts of these items.
This is the amount of power the generator must
produce to keep the items running. See the wattage
reference chart at right.
3. Estimate how many surge (starting) watts you will
need. Surge wattage is the short burst of power
needed to start electric motor-driven tools or
appliances such as a circular saw or refrigerator.
Because not all motors start at the same time, total
surge watts can be estimated by adding only the
item(s) with the highest additional surge watts to the
total rated watts from step 2.
Example:
Tool or
Appliance
Continuous
(Running)
Watts
Surge
(Starting) Watts
CD Player 100 0
Space Heater 1800 0
Drill 500 0
Light (75 Watts) 75 75
2475 Total
Running Watts
75 Highest Surge
Watts
Total Continuous (Running) Watts 2475
Plus Highest Additional Surge Watts + 75
Equals Total Generator Output Required 2550
POWER MANAGEMENT
To prolong the life of the generator and attached devices,
it is important to take care when adding electrical loads to
the generator. There should be nothing connected to the
generator outlets before starting its engine. The correct and
safe way to manage generator power is to sequentially add
loads as follows:
1. With nothing connected to the generator, start the
engine as described later in this manual.
2. Plug in and turn on the first load, preferably the largest
load (highest wattage) you have.
3. Permit the generator output to stabilise (engine runs
smoothly and attached device operates properly).
4. Plug in and turn on the next load.
5. Again, permit the generator to stabilise.
6. Repeat steps 4 and 5 for each additional load.
Never add more loads than the generator capacity. Take
special care to consider surge loads in generator capacity
as previously described.
CAUTION:
Do not overload the generator’s capacity. Exceeding the
generator’s wattage/amperage capacity can damage the
generator and/or electrical devices connected to it.

NOTE: Used oil should be disposed of at an approved
disposal site. See your local oil retailer for more
information.
CLEANING FUEL SEDIMENT CUP
See Figure 11.
The sediment cup prevents dirt and water that may have
gotten into the fuel tank from entering the carburetor. If the
engine has not been run for a long time, the sediment cup
should be cleaned before use.
nTurn the fuel valve to the OFF position.
nRemove the sediment cup using a 10 mm wrench
(not provided).
nRemove the O-ring and filter.
nClean each of the parts in carburetor cleaner or any
comparable cleaning product.
nReinstall the filter, O-ring, and sediment cup. Tighten

nReturn the fuel valve to ON position and check for
leaks.
SPARK PLUG MAINTENANCE
See Figure 12.
The spark plug must be properly gapped and free of deposits
in order to ensure proper engine operation. To check:
nRemove the spark plug cap.
nClean any dirt from around base of spark plug.
nRemove spark plug using wrench provided.
nInspect spark plug for damage, and clean with a wire
brush before reinstalling. If insulator is cracked or
chipped, spark plug should be replaced.
NOTE: If replacing, use the following recommended
spark plugs or equivalent: Champion RN11YC or
NGK BPR6ES.
nSeat spark plug in position; thread in by hand to
prevent cross-threading.
nTighten with wrench to compress washer. If spark
plug is new, use 1/2 turn to compress washer
appropriate amount. If reusing old spark plug, use 1/8
to 1/4 turn for proper washer compression.
NOTE: An improperly tightened spark plug will
become very hot and could damage the engine.
CLEANING THE EXHAUST PORT AND MUFFLER
Depending on the type of fuel used, the type and amount of
oil used, and/or your operating conditions, the exhaust port
and mufer may become blocked with carbon deposits. If
you notice a power loss with your petrol-powered tool, you
may need to remove these deposits to restore performance.
We highly recommend that only qualied service technicians
perform this service.

An occasional light “knocking” or
“pinging” under heavy load is not a cause
for concern. However, if the knocking
or pinging occurs under normal load
at a steady engine speed, the problem
may be with the brand of unleaded fuel
being used.
Switch to a different brand of unleaded
fuel, making sure that the octane rating is
86 or higher. If problem continues, contact
your nearest authorized service center.
If problem persists after trying the above solutions, contact your nearest authorized service center for assistance.
The following symptoms may indicate problems that will affect the emissions level of the unit:
nHard starting or stalling after starting
nRough idle
nMisfiring or backfiring under load
