Operation

Prepare for Operation

Location Selection

Verify the following for safe operation:

• Generator is outdoors and well-ventilated.
• Location is a level and solid surface.
• Location is at least 1.8 m away from buildings, equipment, or combustible material.
• If near a building, it is not near windows, doors, or vents.

[DANGER] Generator exhaust contains carbon monoxide, a colorless and odorless poison, which can cause death in minutes if used indoors.

[NOTICE] Operate only on a solid, level surface. Loose material like sand or grass clippings can ingest debris, blocking vents or air intake.

[NOTICE] Never operate or store the generator in wet conditions (rain, snow, moisture). Always operate or store on a dry surface.

The generator's output is potentially lethal and should not be connected to a fixed electrical installation except by a licensed person.

[WARNING] Operating on a non-level surface can cause tipping, fuel/oil spills, and potential ignition.

[NOTICE] Keep the generator upright during handling, operation, storage, and transport to prevent damage.

[NOTICE] It is recommended to have no connected loads before starting. Unplug devices or switch them off.

Use convenient locations for extension cords, avoiding long cords and potential damage.

Earthing the generator: The equipotential bonding system should not be connected to the general mass of earth through a separate earth electrode. Consult AS/NZS 3010:2017 or a licensed electrician.

Ambient Conditions

Designed for temperatures from -5 to +40°C and altitudes up to 1,000 m.

Operate in shade to prevent additional heat load from solar radiation.

Power output decreases approximately 3.5% for every 300 m increase in altitude due to lower atmospheric pressure.

Application and Duty Cycle

Westinghouse iGen generators are portable, air-cooled, petrol-driven units for independent power supply. Ideal for backup power during mains failure or remote area use (camping, caravanning, field work).

Connect devices via plug and socket-outlet. RCD safety switch models offer enhanced protection.

Connection to fixed electrical installations requires a licensed electrician.

NOTE: RCD safety switch models are not suitable for fixed electrical installation connections due to MEN design causing continuous RCD tripping.

Add Initial Engine Oil

[NOTICE] The generator ships without engine oil. Adding oil before starting is crucial to prevent internal engine damage.

[NOTICE] The generator has a low oil shutdown switch. The engine will stop automatically if oil is too low and cannot be restarted until oil is refilled.

NOTE: The generator is functionally tested and may contain minimal residual oil. Additional oil is required. Do not overfill.

You must add engine oil before the first use. Refer to "Check Engine Oil" and "Add Engine Oil" sections.

Add Fuel

[WARNING] Never refuel while the engine is running. Turn the engine control switch to OFF before refuelling.

[CAUTION] Avoid prolonged skin contact with fuel and inhalation of fuel vapours.

[NOTICE] Do not overfill the fuel tank; spilled fuel may damage plastic parts.

Check fuel level visually with the generator off and stationary. Always fill the tank before operating.

Required Fuel: Use unleaded petrol with an octane rating of 91 or higher and ethanol content not greater than 10%. Unleaded petrol (RON 91) or premium unleaded petrol (RON 95 or 98) is preferred over ethanol blends like E10.

Fuel Tank Filling Steps:

1. Clean the area around the fuel cap.
2. Turn the fuel cap vent clockwise to the ON position (Figure 5).
3. Unscrew the fuel cap anticlockwise.
4. Slowly add fuel, being careful not to overfill. The level should not exceed the red ring inside the fuel strainer (Figure 6).
5. Screw the fuel cap clockwise.
6. Turn the fuel cap vent anticlockwise to the OFF position.

Start the Generator

4. Turn the fuel cap vent anticlockwise to OFF.

During An Emergency

For quick shutdown, follow Step 3 above rapidly.

ECO Throttle Control

To activate ECO mode: Push switch to ON (Figure 9) for small resistive loads (e.g., computer, light). Engine speed minimizes, reducing fuel consumption and noise.

To deactivate ECO mode: Push switch to OFF for large inductive loads (e.g., air conditioner, pump). Engine speed remains higher for maximum starting power.

Overload Reset

An overload or short circuit trips the overload protection, disconnecting AC output. The overload alarm light turns red, and the output indicator light turns off.

To restore AC output:

1. Turn off or unplug all electrical devices/cords from the 240-Volt AC receptacle.
2. Press the generator reset button until the overload alarm light goes off and the output ready light is green.
3. Check that electrical loads do not exceed generator capacity or have a licensed electrician rectify any fault causing a short circuit.
4. Reconnect devices/cords and turn on electrical loads as required.

Residual Current Device (RCD)

Test the RCD using the press button method before connecting equipment and daily during use.

1. Turn off or unplug all electrical devices/cords from the 240-Volt AC receptacle.
2. Start the generator.
3. Unscrew and lift the RCD cover.
4. Press the TEST button (Figure 10, A) to confirm the RCD trips promptly.
5. Reset the RCD to ON (Figure 10, B).
6. Reconnect devices/cords and turn on electrical loads.

Connecting Electrical Loads

The generator powers 240-Volt AC, 50 Hz, single-phase devices. Follow standard safety precautions.

240-Volt AC Loads

Connect devices directly or via extension cords to the 240-Volt AC outlet(s). Lift the spring-loaded cover for access.

Devices use three-pin (spade) 10 Ampere or 15 Ampere plugs (Figure 11). Some double-insulated devices may have a two-pin 10 A plug without an earth pin.

Illustration of 240-Volt AC plugs: A - 15 Ampere, B - 10 Ampere.

[NOTICE] Do not connect devices that will severely overload the 15 Amp outlet, as this may damage the generator or device.

Refer to "240-Volt AC Extension Cords" for selection and use details.

Power Output and Demand

Generator power limits:

• Total 240-Volt AC generating capacity/power output.
• Electric current/power output capacity of each individual 240-Volt AC outlet.

The generator's total power output (running and starting power) is listed in Specifications.

[NOTICE] Do not overload the 240-Volt AC circuit beyond its rated capacity. This can damage the generator or connected devices.

Avoid running the generator completely unloaded for extended periods, as this can damage the engine. Operate with at least one-third of its rated 240-Volt AC power output.

Devices have running power demand (continuous load) and starting power demand (momentary surge, up to seven times running power, especially for motors). Calculate Watts by Voltage x Amps (e.g., 240V x 6A = 1440W).

Resistive devices (bulbs, toasters) have the same starting and running power demand.

For motor-driven devices, estimate starting power demand: 1.2x for small devices, 3.5x for larger ones.

To prevent overloading:

1. Sum the running power demand of all connected devices. This total must not exceed the generator's specified running power output.
2. For the largest motor-driven device, use its starting power demand instead of its running power demand. This total must not exceed the generator's specified starting power output.
3. The total running power demand for devices connected to any single outlet must not exceed the generator's running power output or the outlet's capacity, whichever is lower.

These are approximations. Err on the conservative side. Assume 10A plug devices have up to 2400W running demand, and 15A plugs up to 3600W, then apply starting power multipliers if applicable.

Trial devices to ensure satisfactory performance.

240-Volt AC Extension Cords

Connect devices directly to the generator's outlet whenever possible for best electricity quality.

If extension cords are necessary:

1. Locate the generator conveniently, avoid long cords that can be damaged by traffic.
2. Use the shortest possible cord to minimize voltage drop.
3. Use only a single cord; do not join multiple cords.
4. Use extra heavy duty 15 A extension cords with 3-core cable (at least 1.5 mm² conductor size) and 15 A plugs/sockets. A 15 A plug won't fit a standard 10 A socket.
5. 1.5 mm² or 2.5 mm² cords should not exceed 25 m or 40 m length, respectively (per AS/NZS 3199:2020).
6. [NOTICE] Do not use 2-pin cords; they lack the earth connection provided by 3-pin cords.
7. Do not use cords with visible damage.
8. Do not use rolled-up or knotted cords, as they may overheat.
9. Periodically check the cord's earthing continuity.

Charge External 12 Volt Battery

Use a proprietary mains-powered 12 Volt battery charger connected to the generator's 240-Volt AC outlets.

[DANGER] Wet cell batteries produce explosive hydrogen gas during charging. Ensure charging occurs in a well-ventilated area away from ignition sources. Sulfuric acid in electrolyte can cause severe burns; wear protective glasses, clothing, and gloves. Flush spills with water.

Charging Procedure:

1. Prepare battery (remove vent caps, add demineralised/distilled water if user-maintainable).
2. Connect charger's positive (+) clip (red) to battery's positive (+) terminal.
3. Connect charger's negative (-) clip (black) to battery's negative (-) terminal.
4. Start the generator.
5. Make any necessary charger adjustments per its instructions.
6. Plug charger into generator's 240-Volt AC outlet and switch charger ON. Keep battery away from generator due to gas hazard.
7. Monitor battery; stop charging if it gets hot or electrolyte boils.
8. Monitor charger per its instructions and switch off when indicated.
9. Switch charger OFF and unplug its power cord from the generator.
10. Stop the generator unless powering other devices.
11. Disconnect charger's negative (-) clip from battery.
12. Disconnect charger's positive (+) clip from battery.
13. Refit battery vent caps if applicable.

5. Remove rocker arm cover (Figure 34). Gasket can be reused if intact and undamaged.
6. Remove spark plug to facilitate engine rotation.
7. Pull recoil starter handle slowly until engine is at top dead center (TDC) on compression stroke. Check piston position via spark plug hole and ensure both rocker arms are loose with play (Figure 35).
8. If rocker arms are not loose at TDC on compression stroke, rotate engine 360°.
9. Insert feeler gauge between rocker arm and valve stem to measure clearance.

10. If adjustment is needed, loosen the lock nut.
11. Slide appropriate feeler gauge between rocker arm and valve stem.
12. Tighten adjustment screw onto push rod to obtain specified clearance.

NOTE: You should feel the rocker arm touch the feeler gauge.

13. Hold adjustment screw and tighten the nut.
14. Recheck valve clearance.
15. Repeat for the other valve if necessary.
16. Install gasket, rocker arm cover, spark plug, boot, access cover, and RHS maintenance access cover.

Long-Term Storage

[WARNING] Never store a generator with fuel indoors or in poorly ventilated areas where fumes could contact ignition sources (pilot lights, water heaters, etc.) or sparks.

[NOTICE] Fuel can degrade in as little as 30 days, causing gum, varnish, and corrosion that restricts fuel flow and prevents starting. Such faults are not covered by warranty.

Run the generator monthly for 30 minutes under at least one-third load. If not possible, prepare for long-term storage as described.

Proper preparation protects function and appearance, and aids future starting.

Storage Procedure For 1 – 3 Months

1. Clean the generator (see "CLEAN THE GENERATOR").
2. Add proprietary fuel stabiliser to the fuel tank, then add fresh fuel to maximum capacity (see "Checking and Adding Fuel"). Follow stabiliser manufacturer's recommendations.
3. Start generator and run for 10 minutes to distribute treated fuel.
4. Stop the generator.
5. Ensure engine control switch is OFF.
6. Turn fuel cap vent to OFF.
7. Allow unit to cool, then move to a clean, dry storage place.

Storage Procedure for Greater Than 3 Months

1. Clean the generator (see "CLEAN THE GENERATOR").
2. Drain the fuel (see "Drain the Fuel").
3. Start generator if possible, run without load until it stops from lack of fuel (see "START" and "STOP" procedures).
4. Change the engine oil (see "Change Engine Oil").
5. Remove spark plug (see "SPARK PLUG"). Pour a tablespoon of clean engine oil into the spark plug opening. Cover opening with a rag, slowly pull recoil starter handle several times to distribute oil and protect cylinder wall from corrosion.
6. Reinstall spark plug (see "Clean and Replace the Spark Plug").
7. Slowly pull recoil starter handle until resistance is felt (piston at TDC on compression stroke, valves closed). This helps prevent internal corrosion.
8. Move unit to a clean, dry storage place.

Removal From Storage

Follow normal pre-operation checks and starting procedures (see "PREPARE FOR OPERATION").

Use only fresh fuel. If oil was added to the cylinder, expect brief smoke on startup, which is normal.

Dismantle and Dispose

Dismantling is only required for major repair/overhaul or final disposal. This should be done by a mechanically proficient person or an authorized Westinghouse service dealer.

Before dismantling:

1. Stop the generator.
2. Drain engine oil.
3. Drain fuel.

[NOTICE] Do not pollute the environment by improper or illegal disposal of waste fluids or the generator. Dispose of hazardous items at authorized waste collection/recycling facilities. The generator is mostly metal and recyclable.

Troubleshooting

[WARNING] Read and understand this manual before servicing. Failure to follow instructions may void warranty, cause injury, or damage.
