Westinghouse WHXC3750, Instruction Manual

MAINTENANCE

Proper care should be taken to prepare the generator 

for any long-term storage. This will protect the 

generator’s function and appearance, and will make it 

easier to start when required on the next occasion.

Storage Procedure for 1 – 3 Months

1.  Clean the generator as outlined in Cleaning the 

Generator on page 38.

2.  Add a proprietary fuel stabilizer to the fuel tank 

and then add fresh fuel up to the tank’s maximum 

capacity (see checking and Adding Fuel on page 

20). Follow the manufacturer’s recommendation for 

correct amount of stabilizer to add.

3.  Start the generator and then run it for 10 minutes 

to ensure that treated fuel is distributed throughout 

the engine’s fuel system. Then stop the generator 

and turn the fuel shutoff valve to the OFF position.

4.  Allow the unit to cool down and then move it to a 

clean, dry place for storage.

5.  For electric-start models equipped with a 12 Volt 

battery, the battery should be re-charged at 

intervals of no more than 3 months (see Charging 

the Battery on page 40).

Storage Procedure for Greater than      

3 Months

1. Clean the generator as outlined in Cleaning the 

Generator on page 38.

2.  Drain the fuel (see Draining the Fuel on page 41).
3.  Change the engine oil (see Changing Engine oil 

on page 31).

4.  Remove the spark plug (see spark Plug 

Maintenance on page 36) and pour a tablespoon 

of clean engine oil into the spark plug opening. 

While placing a clean rag over the spark plug 

opening, slowly pull the recoil starter handle to 

rotate the engine several times. This will distribute 

the oil and protect the cylinder wall from corrosion 

during storage.

5.  Re-install the spark plug (see spark Plug 

Maintenance on page 36).

6.  Move the generator to a clean, dry place for 

storage.

7.  For electric-start models equipped with a 12 Volt 

battery, the battery should be re-charged at 

intervals of no more than 3 months (see Charging 

the Battery on page 40).

Removal from Storage

Follow the normal procedures for pre-operation checks 

and starting 

(see Before Starting the Generator on 

page 19).

Use only fresh fuel to re-fill the tank, if necessary, 

rather than re-using the old fuel.

If oil was inserted into the cylinder prior to storage, the 

exhaust may smoke for a short while after starting the 

generator; this is normal and will cease within a minute 

or so of running time.

DisMantling anD DisPosal

There is no requirement for the generator to be 

dismantled during normal operation other than for 

major repair/overhaul or prior to final disposal at the 

end of its service life.
Dismantling should only be carried out by a 

mechanically proficient person with access to proper 

tools or alternatively by your authorized Westinghouse 

service dealer for a fee.
Before dismantling:

1.  Stop the generator (see Stopping the Generator 

on page 24).

2.  Drain the engine oil (see Changing Engine Oil on 

page 31).

3.  Drain the fuel (see Draining the Fuel on page 41).
4.  Disconnect and remove the battery, if equipped 

(see 12 Volt Battery Maintenance  on page 40).

NOTICE

Do not pollute the environment by improper or 

illegal disposal of the waste fluids or 12 Volt battery. 

Dispose of these hazardous items only at an 

authorized waste collection/recycling facility.
Do not pollute the environment by improper or illegal 

disposal of the generator either as a whole or in 

parts. Take the unwanted unit or components to 

your local recycling centre instead. The generator is 

made almost entirely of metal that can be recycled.
