Spark Plug Maintenance; Spark Arrestor Maintenance; Long Term Storage - Predator 9000 Owner's Manual & Safety Instructions

Spark plug Maintenance

1. Disconnect spark plug cap from end of plug.
Clean out debris from around spark plug.
2. Using a spark plug
wrench, remove
the spark plug.
3. Inspect the spark plug:
If the electrode is oily,
clean it using a clean,
dry rag. If the electrode
has deposits on it,
polish it using emery
paper. If the white
insulator is cracked or
chipped, the spark plug needs to be replaced.
NOTICE: Using an incorrect spark plug may
damage the engine. See the Specifications chart
for your Generator for the type and gap required.

Spark Arrestor Maintenance

1. Wait for Engine exhaust and
Muffler to cool completely.
2. Remove Spark Arrestor from end of exhaust.
3. Brush all carbon off Spark Arrestor using
a stiff brush (sold separately).
Long-Term Storage
When the equipment is to remain idle for longer than
20 days, prepare the Engine for storage as follows:
1. CLEANING:
Wait for Engine to cool, then clean Engine with
dry cloth. NOTICE: Do not clean using water.
The water can cause rust damage over time. Apply
a thin coat of rust preventive oil to all metal parts.
2. FUEL:
Gasoline Treatment/Draining the Fuel Tank
To protect the fuel tank during storage, fill the
tank with fresh gasoline that has been treated
with a fuel stabilizer additive. Follow fuel
stabilizer manufacturer's recommendations
for use. Refer to Checking and Filling Fuel
Checking and Filling Fuel on page 11.
Aged gasoline that has not been treated with
stabilizer ahead of time must be safely drained
away and not run through the engine.
WARNING! TO pREVENT SERIOUS
INJURY FROM FIRE:
Fill tank in a well-ventilated area away
from ignition sources. If the engine
is hot from use, shut the engine off and
wait for it to cool before adding fuel. Do not smoke.

the plug's gap to the specification on the
Specifications chart. Do not pry against the
electrode, the spark plug can be damaged.
5. Install the new spark plug or the cleaned spark plug
into the engine. Gasket-style: Finger-tighten until
the gasket contacts the cylinder head, then about
1/2-2/3 turn more.
Non-gasket-style: Finger-tighten until the plug
contacts the head, then about 1/16 turn more.
NOTICE: Tighten the spark plug properly.
If loose, the spark plug will cause the engine
to overheat. If overtightened, the threads
in the engine block will be damaged.
6. Apply dielectric spark plug boot protector
(not included) to the end of the spark plug
and reattach the wire securely.

container under the Carburetor and carefully
remove the Drain Bolt from the bottom of the
Carburetor Bowl, allowing the fuel to drain
completely. Replace the Drain Bolt after draining.
WARNING! To prevent serious
injury and fire, close the Fuel Valve
before draining the Carburetor.
3. LUBRICATION:
a. Change engine oil.
b. Clean out area around spark plug.
Remove spark plug and pour one tablespoon of
engine oil into cylinder through spark plug hole.
c. Replace spark plug, but leave
