ENGINE and repairs.
Be sure that the generator is properly grounded to an external ground path prior to
operation. Refer to the section entitled " Grounding Instructions " for proper ground-
ing procedures.
Be sure that the generator is operated only by persons who have read and who
understand these instructions.
Be sure that the generator is placed on a flat level surface prior to and during oper-
ation. The generator must not slide or shift during operation.
Keep all persons away from the generator during operation.
Do not allow persons wearing loose clothing or jewellery to start or operate the gen-
erator. Loose clothing or jewellery may become entangled in moving compo-
nents, causing equipment damage and/or personal injury.
Be aware of moving parts and hot surfaces that occur during normal operation of
this generator.
Be sure all devices are switched off prior to connecting them to the generator.
Be sure that all tools and appliances are in good working order and are correctly
grounded.
Never operate the generator with damaged, broken or missing parts, or with any
guards or covers removed.
Do not refill the fuel tank while the engine is running, or still hot.
Be careful to prevent fuel spillage during refills.
Be sure the fuel tank cap is securely in place before starting the engine.
Allow engine to cool before refuelling, or servicing.
Never refuel whilst smoking or in the vicinity of a naked flame.
Take care not to spill any fuel on the engine, exhaust or any part of the generator.
Should any fuel make contact with your clothes; change and wash them immedi-
ately.
If any fuel makes contact with your skin wash with soap and water immediately.
If you swallow any fuel, inhale any vapour or allow contact with your eyes, seek
medical attention immediately.
Be sure to store petrol in clean containers that do not contain water, dirt or rust be-
cause this will reduce the life of the engine; ensure that all local fuel storage laws
are followed.
Never operate this generator in an explosive atmosphere or near any flammable
sources.
Always operate this generator in a well ventilated area to reduce the risk of suffoca-
tion.
Do not operate this generator on wet surfaces or in the rain.
Do not operate the generator or any electrical items with wet hands.
Never drag the generator with power cords or by any means to move it; only move
the generator with the carrying handles.
Never cover the generator or restrict the exhaust or air flow in any way.

EXPLODED DRAWING SAFETY INSTRUCTIONS....cont
MAIN GENERATOR UNIT company employee is working on an electrical line believing it to be "dead" and cur-
rent created by the generator is in the line, shock or electrocution may occur.
The key to better safeguard against these dangers is professional installation by a
qualified electrician and the installation of a generator transfer switch.
Keep in mind a generator burns fuel and must be run in a well ventilated area, it must
not be run in a garage or other outbuilding.
Cords used to connect the generator to the lights and appliances must be correctly
sized to prevent overheating or damage to the equipment as well, again if you are
unsure ask a suitably qualified electrician.
GROUNDING INSTRUCTIONS
Earth / Ground Terminal
1. Use the ground terminal (see picture above) on the generator to connect the unit to
a suitable ground source. Securely fasten the end terminal of the ground wire to the
ground terminal on the generator.
2. The ground wire should be made of more than 0.75 square millimetre wire. Too thin
wire may not provide an adequate ground path.
3. The other end of the ground wire must be securely fastened to an approved
ground source. Refer to the local regulations for ground source information. If not sure
of regulations or procedures, obtain assistance from a qualified (licensed or certified )
electrical technician
CAUTION: The warnings and cautions mentioned in this user manual can not cover all possible
conditions and situations that may occur. It must be understood by the operator that common
sense and caution are factors which cannot be built into this product, but must be applied.

FILLING THE CRANKCASE WITH OIL / CHECKING THE OIL LEVEL
STOPPING THE GENERATOR
Caution: The generator is drained of oil at the factory prior to shipping. SAE
10W-30 oil or equivalent is recommended for these generators. In an emergency:
Simply press the engine switch to the off position.
Note: When checking the oil level; always ensure that the generator is
placed on a firm level surface. In normal conditions:
Remove any load from the generator.
Ensure that the generator is on a flat level surface. Press the engine switch to the off position.
Turn the fuel tap to off.
Remove the filler cap / Dipstick by turning it anti-clockwise.
Slowly pour the oil into the crankcase.

The oil level should be checked every 8 hours or daily.
The oil should be changed after the first 20 hours of operation; thereafter change the CHANGING THE OIL
oil after 50 hours of operation or less if the generator is operated under constant heavy
loads or in high ambient temperatures. Change The Engine Oil (every 50 hours of use).
1. Turn the oil filler cap counter clockwise and remove from the crankcase.
2. Loosen and remove the oil drain bung and allow the oil to drain into a suitable
container.
3. Refit and tighten the oil drain bung once all of the oil has drained.
4. Fill the crankcase to the max level with fresh oil (see page 10); we recommend
the use of SAE 10W-30 oil.
5. Refit the oil filler cap.

Proceed to use the device normally.
USING DC POWER Note: Never overfill the fuel tank; leave a small air gap at the top.
Fuel capacity: 6 Litres.
Note: The DC output on the generator is for charging batteries only - see
specifications on page 8
Note: When re-fuelling always ensure that the fuel filter (supplied) is in place
under the filler cap, as foreign matter or debris will cause damage to the
engine and greatly reduce the life of the generator.
Caution: Make connections to the battery only after starting the engine.
Caution: To reduce the possibility of creating a spark near the battery,
connect the battery charging lead to the battery first and then to the
generator.

Connect the red wire to the positive terminal on the battery and the black wire
to the negative terminal of the battery - NEVER REVERSE THE POLARITY!
