Westinghouse Gas Generator Owner's Guide: Features, Maintenance & Common Issues
Note: This is our own general guide to how Westinghouse gas generators typically work and what to expect across the lineup. It is not the official manufacturer manual, and it is not model-specific. Your exact unit's controls, specifications, safety procedures, and warranty terms are detailed in your official Westinghouse manual, which is the authoritative source for those details. This guide explains the general principles, common features, and practical ownership tips.
How a Westinghouse Gas Generator Works
A gas generator converts fuel (gasoline or propane, depending on the model) into electrical power through a combustion engine connected to an alternator. When you start the engine, it spins the alternator's rotor, which generates AC current that you can draw through the unit's outlets.
Most Westinghouse generators in the consumer range are portable or standby units. Portable models sit outside and connect to appliances via heavy-duty extension cords or a manual transfer switch. Standby units are larger, installed permanently, and can automatically switch on during a power outage. This guide focuses on the more common portable and semi-portable models, though the fundamental principles apply across Westinghouse's gas generator lineup.
The core systems you'll interact with are:
- Fuel system — tank, fuel line, carburetor
- Engine — typically air-cooled, single-cylinder or multi-cylinder
- Alternator — generates the electrical output
- Control panel — start/stop switch, outlets, circuit breakers, hour meter
- Cooling and exhaust — manages heat and emissions
- Frame and wheels — for transport (on portable models)
Common Features and Controls on Westinghouse Generators
While exact layouts vary by model and year—always refer to your official manual for your specific unit—most Westinghouse gas generators share a similar set of controls and features.
Engine Start and Shutdown
Nearly all Westinghouse generators have a pull-cord starter or electric starter (battery-powered push-button). Some units offer both. Pull-cord models require a sharp, deliberate pull to turn over the engine; electric starters are more convenient but depend on a charged battery.
A choke control (manual or automatic) enriches the fuel mixture for cold starts. On first startup or after long storage, you'll typically move the choke to a richer position, then gradually return it to normal as the engine warms.
The on/off switch or fuel valve sits on the engine block and controls whether gasoline flows to the carburetor. This switch must be in the off position before you stop the engine for storage or maintenance.
Power Output and Outlets
Your generator's control panel displays AC outlets (most common—standard 120V household plugs) and sometimes DC outlets (12V, for charging batteries). Larger units may include a 220V outlet for higher-load appliances. The number and type of outlets vary significantly by model.
Each outlet may be protected by its own circuit breaker or a main breaker for the entire unit. If an outlet stops working, the first troubleshooting step is to check whether its breaker has tripped (usually visible as a red or black button that sticks out). Push it back in to reset.
Fuel and Oil Indicators
A fuel gauge (analog or, rarely, digital) shows how much gasoline is in the tank. Some Westinghouse models include a low-fuel indicator light that comes on when the tank reaches a certain level.
The oil level window on the engine block lets you check the engine oil without removing the dipstick. Oil level is critical—running the generator on low oil causes rapid engine damage. Many Westinghouse units have an automatic low-oil shutoff that stops the engine if oil drops below a safe level; consult your manual for the exact threshold.
Load and Runtime Indicators
An hour meter (if present) tracks cumulative engine running time, useful for scheduling maintenance. Some newer units display estimated runtime remaining based on current load and fuel level, though this is an estimate and varies with actual power draw.
The load on your generator affects fuel consumption and runtime significantly. A half-loaded generator typically runs longer per tank than a fully loaded one.
Routine Maintenance for Westinghouse Gas Generators
Keeping your generator in good condition means routine checks and seasonal care. Your official manual specifies intervals for your exact model, but the practices below are standard across Westinghouse's gas generator lineup.
Oil and Filter Changes
Gas generators burn through oil gradually, and checking the level before every use is a best practice. Oil changes are typically needed every 50–100 hours of operation, or annually if the unit runs less frequently. Synthetic or premium conventional oils can extend intervals; check your manual for the recommended type and viscosity for your model.
To change the oil:
- Run the engine for a few minutes to warm the oil (makes it flow better).
- Turn off the engine and allow it to cool for at least 5 minutes.
- Locate the oil drain plug (usually at the base of the engine) and place a drain pan beneath it.
- Remove the drain plug and let old oil drain completely (10–15 minutes).
- Replace the drain plug and torque it hand-tight.
- Refill with the correct amount and type of oil (check your manual for capacity).
- Wipe the exterior with a clean rag and check the level again.
Air Filter Maintenance
The air filter prevents dust and debris from reaching the engine. Inspect it monthly during the active season or before every use if you run the generator often.
A paper or foam air filter can usually be cleaned by gently tapping it (never blow-dry it with compressed air, as this can push particles deeper into the fibers). If it's heavily soiled or damaged, replace it. Consult your manual for the correct filter type and part number for your model.
Spark Plug Checks
The spark plug ignites the fuel-air mixture inside the engine. Over time, the electrodes foul or wear, reducing spark strength. Inspect the spark plug annually or every 100–150 hours of operation.
To access it, locate the spark plug wire on the engine, pull the boot off gently, and unscrew the plug with a spark plug socket. A healthy spark plug has a light tan or gray electrode; heavy black deposits or a gap larger than what your manual specifies means replacement is due.
Fuel System Care
Gasoline degrades over time, especially in temperate storage. Fuel left in the tank and carburetor over winter can gum up, causing hard starts or rough running the next season. To prevent this:
- Use fuel with a stabilizer (added to a full tank of fresh gasoline) if you plan to store the generator for more than a month.
- Alternatively, run the fuel out by letting the generator idle with the fuel valve off until it stops, then store it empty.
- Some owners prefer to drain the carburetor by removing the carb drain screw (if present) and letting fuel drip into a container. Consult your manual for your model's specific procedure.
For propane-fueled Westinghouse models, no stabilizer is needed. Simply turn off the fuel valve, run the engine until it stops, and store the propane cylinder in a cool, dry place.
Seasonal Storage and Startup
Before storing your generator for winter or an extended period:
- Change the oil (old oil can become acidic over time).
- Drain or stabilize the fuel (see above).
- Remove the spark plug and pour a teaspoon of clean oil into the cylinder; pull the cord a few times to distribute it (protects internal parts from rust).
- Store the unit in a dry place, away from sunlight and extreme temperature swings.
When you're ready to use it again, reinstall the spark plug, check the oil level, add fresh fuel, and follow the cold-start procedure in your manual.
Common Issues and Troubleshooting
Hard Starts or Won't Start
Likely causes: stale fuel, low oil, fouled spark plug, clogged air filter, or a weak battery (if electric start).
- Check the oil level first; add oil if low and try again.
- Inspect and clean or replace the air filter.
- Check or replace the spark plug.
- If the unit has been stored over winter, follow the fuel drain/stabilizer procedure from your manual to clear old fuel from the carburetor.
- For electric-start models, ensure the battery is charged (usually a small 12V battery); recharge it and retry.
If the engine turns over but won't fire, the issue is likely spark, fuel, or compression—all requiring the official manual's diagnostic steps or professional service.
Loss of Power or Low Output
Likely causes: overload (too many appliances at once), clogged air filter, fouled spark plug, low fuel, or a tripped circuit breaker.
- Unplug non-essential loads and try running only one high-draw appliance.
- Check the circuit breaker on the outlet or main panel—reset it if tripped.
- Inspect the air filter and clean or replace it.
- Ensure the fuel tank has adequate gasoline and the fuel valve is fully open.
If power loss persists, the alternator or internal components may be failing—stop using the unit and consult a service professional or your manual's troubleshooting section.
Smoke or Unusual Odors
Likely causes: too much oil, fuel leak, overheating, or carburetor issues.
- If you smell fuel, turn off the unit immediately, check for leaks in the fuel line or fittings, and do not restart until the leak is repaired.
- Excess smoke (white, blue, or black) often means oil is burning. Stop the engine, allow it to cool, and check the oil level; if it's overfilled, drain excess oil back to the correct level.
- A burning electrical smell suggests a serious internal fault—do not use the unit.
Any of these conditions requires the official manual's safety guidelines or professional repair.
Carburetor Issues (Hard Start, Rough Idle, Fuel Leaks)
The carburetor mixes fuel and air for combustion and is one of the most common failure points, especially after prolonged storage.
- If the unit starts but runs rough or surges, the carburetor may be partially clogged. Shut off the fuel valve and let the unit run until it dies (clearing the carburetor of fuel).
- For more thorough cleaning, carburetor removal and disassembly is beyond typical owner maintenance—consult your manual for step-by-step guidance or contact a service center.
Fuel Leaks
Any visible fuel dripping or pooling under the generator is a serious safety and environmental concern.
- Turn off the engine immediately and do not restart.
- Check the fuel cap, fuel line connections, and carburetor drain for cracks or loose fittings.
- Tighten loose connections by hand (do not over-tighten plastic fittings).
- If a fuel line is cracked, it must be replaced—consult your manual for the correct size and type of hose, or seek professional help.
