Charging the battery
1. Disconnect the leads from the battery.
2. Fully loosen the battery fluid filler caps.
3. Fill the battery cells with distilled water to the upper limit if
the battery is empty.
4. Measure the specific gravity fluid by using a hydrometer
and calculate the charging time in accordance with the
table shown.
5. For a fully charged battery, the specific gravity range shall
be within 1.26 to 1.28. It is recommended to be checked
and confirmed every hour.
6. Connect the DC plug lead (17) into the DC socket (7)
and connect the alligator clips to the correct polarity.
Press the DC reset button (4) to reset in case the DC
supply had previously been overloaded.
The generator will charge batteries up to 600CCA capacity
provided the battery is in reasonable condition.
Batteries of larger capacity may charge but will depend on
the condition and also the level of charge in the battery.
In cases where the current exceeds the rating of the
generator, the circuit breaker on the DC side will open
circuit, and will need to be re set to continue.
Note. The 13.8V DC outlet on this generator is controlled
by a DC regulator. This DC outlet should only be used for
charging 12Volt Lead Acid Batteries. Both the 240V outlet
and the 13.8V DC outlets can be used at the one time,
but by using the 240V outlet, the DC outlet current will be
higher, thus providing a faster charge. If the DC over current
reset button operates, reset the DC button but remove /
reduce any 240V AC appliances from the generator.
WARNING. Prior to connecting any appliance to the
generator, check the rating label of the appliance. The
generator is rated at 900W so if the appliance being
connected is higher than 900W, the protective cut out on the
generator may operate to prevent over load damage to the
generator. The generator will withstand short operation and
loads up to 1000W or the generator may stop.
Note: Motorised products will require more energy upon
start up and products which are rated below 900W may not
start if the starting current is excessive..
It should also be very clearly understood that output voltage
fluctuations will occur when various loads are connected
and disconnected. It is NOT recommended to connect
any electronic equipment to the generator without a
voltage or surge protector. Computers, televisions, and
stereo equipment can be very sensitive to the input supply
and could be damaged if protective equipment is not
used in conjunction with this generator. This also includes
caravans where electronic equipment is incorporated as
part of the wiring.

4. Lubricate the filter using motor
oil (SAE #30).
5. Thoroughly squeeze the filter
removing excess oil.
6. Replace air filter back into
the engine.
7. Secure the cover back onto
the side panel of the generator.

Tap extension fuel filter
A small fuel filter has been fitted to the inlet side of the fuel
valve (19), inside the tank. This tap extension fuel filter (18)
prevents any dirt in the fuel from entering the fuel system.
The procedure for removing this filter in order to replace or
clean it is given below.
Note. The following procedure should be performed in a well
ventilated area, with no naked flames, sparks, or cigarettes.
Safety glasses should also be worn and engine switch (8)
set to the OFF position.
1. Completely empty the tank of fuel. Ensure the fuel tap
(19) is in the OFF position.
2. Compress the two wire
arms of the hose clamp on
the outlet hose at the tap
(19) and slide the clamp
back from the end of the
hose by approx. 25mm.
Slide the fuel hose off the
outlet of the tap (19).
3. Loosen the lock nut locking
the tap (19) on to the tank.
Unscrew the tap from the
tank and withdraw the tap
from the tank. Be careful
not to lose the small seal
on the thread of the tap.
4. Unscrew the tap extension
fuel filter (18).
Note. This filter can be
cleaned in petrol to remove
any build-up of dirt on the
outside of the filter, or the
filter can be replaced. Do not
operate the generator without
this filter in place. To replace
the filter after cleaning, or
with a new filter, simply screw
the filter into the inlet side of
the tap.
5. Ensuring the small seal
is fitted to the tap thread,
screw the tap back into the
tank by a FULL 3–4 turns.
Orientate the tap so the
outlet of the tap is towards
the rear of the tank, and
the tap control is to the
right hand side of the tank.

Holding the tap firm, tighten
the lock nut, ensuring the
seal is clamped between
the lock nut and the tank.
6. Refit the fuel hose to the
outlet of the tap and with
the wire arms compressed,
slide the hose clamp up
onto the connection of the
hose and the tap.
7. Refill the tank with fuel and ensure there are no leaks
between the tap and the tank, and with the fuel tap turned
on, ensure there are no leaks where the fuel hose is fitted
to the outlet of the tap.
Petrol tank filter
1. Stop the engine.
2. Turn the fuel lever to the ‘off’
position.
3. The petrol tank filter is located
directly under the petrol cap
(2). This protects impurities
entering the fuel tank during
refuelling.
4. Remove the filter & wash thoroughly in a solvent.
5. Re-assemble.
Cleaning
1. Keep your machine clean. The outside of the machine
can be cleaned using a damp soft cloth with a mild
detergent if required. Never use water to clean the
generator as it may cause damage to internal parts.
2. Some maintenance products and solvents may damage
the plastic parts; these include products containing
benzene, trichloroethylene, chloride and ammonia.
3. Use a vacuum to clean air inlet and outlet louvres of
the alternator.
4. Take special care to keep the ventilation inlets/outlets
free from obstruction; cleaning with a soft brush followed
by a compressed air jet will usually be sufficient to ensure
acceptable internal cleanliness.
5. Wear eye protection when carrying out cleaning.
Repairs
Only an authorised service centre should repair the generator.
