Check the engine Oil

WARNING: This engine is not filled with oil from the factory. Any attempt to crank or start the engine before it has been properly filled (with the recommended type and amount of oil) may result in engine damage and void your warranty.

Place the generator on a level surface with engine stopped.

• Remove the dipstick and wipe it clean.
• Reinstall dipstick into tube; rest on oil fill neck, DO NOT thread cap into tube.
• Remove the dipstick again and check oil level. Level should be at top of indicator on dipstick.
• If the level is below or near the lower limit, fill to the upper limit (marked with “H”) of the dipstick with the recommended oil. Reinsert and fully tighten the dipstick.

Oil is a major factor affecting performance and service life of an engine. Use 4-stroke automotive oil SAE10W-30. Regular oil changes will extend the life of your generator.

LEVEL GROUND – Operate generator only on level surface. The engine is equipped with a low oil sensor that will automatically stop the engine when the oil level falls below the safe limit. To avoid the inconvenience of an unexpected shutdown, fill to the upper limit and check the oil level regularly.

Check the Fuel Level
CAUTION: Pressure can build up in the fuel tank.

Allow the generator to cool for at least two minutes before removing fuel cap. Loosen the fuel cap slowly to relieve any pressure in the tank.
With the engine stopped, check the fuel level gauge. Refill the fuel tank if necessary.

• Use clean, fresh, unleaded petrol only. 91 Octane
• DO NOT add oil to the petrol. The engine is a 4 stroke and does not need pre-mix.
• Fill only to the upper limit mark shown by the level indicator. Allow 25mm air gap in the tank to allow room for fuel expansion.

Safe Fuel Handling
DANGER: FIRE OR EXPLOSION – Petrol is highly flammable and extremely explosive. A fire or explosion can cause severe burns or death.

• Keep flammable items away while handling petrol.
• Fill fuel tank outdoors and in a well-ventilated area with the engine stopped.
• Avoid the use of open containers.
• Always wipe off spilled fuel and wait until the fuel has dried before starting the engine.
• DO NOT operate the engine with known leaks in the fuel system.
• Use proper fuel storage and handling procedures. DO NOT store fuel or other flammable materials nearby.
• Empty the fuel tank before storing or transporting this engine.
• Keep fire extinguisher handy and be prepared if a fire starts.
  CAUTION: NEVER use engine or carburettor cleaner products in the fuel tank or permanent damage may occur.
• It is important to prevent gum deposits from forming in fuel system, such as the carburettor, fuel filter, fuel hose or tank during storage. Also, any alcohol-blended fuels (called gasohol, ethanol or methanol) can attract moisture, which leads to separation and formation of acids during storage.
• Acidic fuel can damage the fuel system of an engine while in storage. Be sure to review the Storage instructions.
• Petrol/Alcohol Blends: can be acidic and attract moisture and therefore are not recommended. Effects of old, stale or contaminated fuel may void your warranty.
  CAUTION: To minimise gum deposits in your fuel system and to ensure easy starting, do not use fuel left over from the previous season.

Starting the generator
The generator may be hard to start with electrical devices connected.

1. Perform the operating checklist.
2. Turn the fuel valve to the ‘ON’ position.
3. Disconnect all electrical devices from the generator before starting the engine.
4. The engine is equipped with an auto-choke.
   NOTE: Choke position for starting may vary depending upon temperature and other factors. When re-starting a warm engine, the choke should be left in the HALF or OFF position.
5. Set the master switch to the run position.
6. ELECTRIC START – press the engine start button or use the wireless starter fob. The engine should fire in less than 5 seconds.
   MANUAL START – Take hold of the recoil handle and slow pull until there is a sense of resistance, and then quickly pull to start.
   CAUTION: Ensure that the recoil rope is not damaged and repair if required.
   Take care when manual starting in case of kickback.
   If the engine fails to start after 3 attempts or stops after starting; inspect and ensure that the generator is placed on horizontal surface and check the fuel and engine oil levels.
7. Once the generator is running smoothly, ensure the choke valve is in its ‘OFF’ position.

When connecting the generator with electrical equipment. DO NOT start or stop the engine while electrical equipment is in an ‘ON’ state.
There is a continual low level current draw on the battery to allow the remote (I wireless start etc to operate. When not in use, make sure that the engine switch is in the OFF position otherwise the battery voltage will drain over time.

Use of a ground fault circuit interrupter (RCD) is strongly encouraged, especially in any damp or highly conductive areas, such as metal decking or steel work.

Maximum electrical capacity

WARNING: NEVER overload the generator. Exceeding the capacity of generator can damage the generator and/or electrical devices connected.
All electrical devices and appliances have a power rating.
Ensure your generator can supply enough rated (running) and surge (starting) watts for the electrical devices you intend to power at the same time.

Calculating the Expected constant load

1. Select the electrical devices you intend to power at the same time.
2. Calculate that the total amount of power you need to run all devices and ensure it is less than the rated output of the generator.
   You may need to check the items rated (running) watts in their manuals or from the manufacturers nameplate. If the appliance, tool or motor does not give wattage, multiply Volts times Ampere rating to determine Watts (voltsx amps = watts).

Calculate the Surge load requirement
Devices which have an induction type electric motor i.e. garage door openers, air compressors, pumps, refrigerators, circular saws etc create additional load as they start up.
This surge current can be 3 – 5 times greater than the appliance rated size.
i.e. Starting ‘Direct on Line’, a water pump rated at 750W may momentarily require a surge current equivalent to 2300W or greater.

NOTE: Not all motors start at the same time so allow total surge watts for the largest electric
motor you intend to power.

Identify how many surge (starting) watts you may need.
Add the surge wattage requirement on top of the expected constant load requirement.

AC OVERLOAD RESET
If the AC power outlet is overloaded, the circuit breaker will cut out the power to the device.
If tripped remove device/load and reset switch.

Stopping the generator

WARNING: NEVER stop the engine with electrical devices V connected and the connected devices turned ‘ON’.

1. Turn off all electrical equipment and disconnect all from the generator.
2. Allow the generator to run at no load for a few minutes to stabilize internal temperatures of the engine and generating set.
3. Press the rocker ignition switch to the ‘OFF’ position.
4. Turn the fuel valve to the ‘OFF’ position
