Spark Arrestor Service; Storage - Westinghouse iGen4500DFcv User Manual

7. Measure the spark plug electrode gap with a wire-type
feeler gauge. If necessary, correct the gap by carefully
bending the side electrode.
Spark plug gap: 0.024 – 0.032 in. (0.60 – 0.80 mm)
8. Carefully install the spark plug finger tight, then tighten
as additional 3/8 to 1/2 turn with the spark plug wrench.
9. Install the spark plug boot and engine service cover.

SPARK ARRESTOR SERVICE

Check and clean the spark arrestor after every 100 hours
of use or six months. Failure to clean the spark arrestor will
result in degraded engine performance.
1. Place the generator on a level surface and allow the
muffler to cool before servicing the spark arrestor.
2. Remove the screw securing the spark arrestor bracket.
3. Remove the bracket screen, and spark arrestor from the
generator.
4. Gently clean the screen and spark arrestor screen using
a wire brush.
5. Reinstall the spark arrestor, screen, and bracket. Tighten
the screw securely.
Spark Arrestor: Part# 6790
MAINTENANCE

STORAGE

Proper storage preparation is required for trouble-free
operation and generator longevity.
Gasoline stored for as little as 30 days can deteriorate,
causing gum, varnish, and corrosive buildup in fuel lines,
fuel passages and the engine. This corrosive buildup
restricts the flow of fuel, which can prevent the engine
from starting after a prolonged storage period. The use
of fuel stabilizer significantly increases the storage life of
gasoline. Full-time use of fuel stabilizer is recommended.
Follow the manufacturer's instructions for use.
STORAGE TIME
Less than 1 month
2 to 6 months
6 months or longer
SHORT TERM STORAGE
• Allow the generator to cool a minimum of 30 minutes
before storage.
• If operating on LPG, turn the propane tank valve to the
fully closed position and disconnect the LPG/propane
hose from the generator and propane tank.
• Replace all protective covers on the generator control
panel.
• Wipe the generator with a moist cloth. Clean any debris
from the air inlets under the control panel and muffler
cooling vents.
• Store the generator in a well-ventilated, dry location
away from sparks, open flames, pilot lights, heat, and
other sources of ignition such as areas with a spark-
producing electric motor or where power tools are
operated.
• Do not store the generator, gasoline, or propane tanks
near furnaces, water heaters, or any other appliances
that produce heat or have automatic ignitions.
• With the engine and exhaust system cool and all
surfaces dry, cover the generator to keep out dust. Do
not use a plastic sheet as a dust cover. Non-porous
materials trap moisture and promote rust and corrosion.
LONG TERM STORAGE
Even properly stabilized fuel can leave residue and cause
corrosion if left long term. If storing the generator for two to
six months, drain the float bowl to prevent gum and varnish
buildup in the carburetor.
