Inspecting
the Spark Plugs
Clean spark plugs every 50 hours and replace the
plugs every 500 hours of operation. Use the
recommended
spark plugs gapped for 0.6mm to
0.7mm.
1. Stop the engine and pull the spark plug wires off of
the spark plugs.
2. Clean around the spark plugs and remove them
from the cylinder head.
3. Clean off carbon deposits on the spark plug
electrode using a plug cleaner or wire brush.
4. Set the spark plugs' gap to 0.6mm to 0.7mm.
Install the correctly gapped spark plugs into the
cylinder heads.
Service Air Cleaner
The engine's air cleaner is one of the most important
areas to maintain. The engine will not run properly and
will be damaged if it is run with a dirty air cleaner
system.
Clean the urethane
foam element every 50 hours
of operation.
Clean paper element every 50 hours
of operation
and replace every 200 hours. Clean or
replace more often in dusty or dirty conditions.
CAUTION!
Never run this equipment without the
complete air cleaner system installed on the engine.
Failure to do so will result in premature engine wear
and significantly reduced engine life.
•
The air cleaner paper inner element and urethane
foam outer element can be removed after removing
knob and air cleaner cover. When installing, set the
paper element and urethane foam on the air
cleaner base. Check that the grommet is in
position, and then install the cover with the knob
tightened securely.
Cleaning Urethane Foam Element:
•
Wash and clean the urethane foam in kerosene.
Saturate in a mixture of 3 parts kerosene and
1 part engine oil, and then squeeze to remove
excess oil. Clean or replace urethane foam
element every 50 hours (more often in dusty
conditions).
Paper Element
•
Clean by tapping gently to remove dirt and blow off
dust. Never use oil. Clean or replace more often in
dirty or dusty environments.
NOTE: If you need to order a new air filter, please call
1-800-336-PART.
Engine
Governed
Speed
CAUTION!
The engine speed was properly adjusted
at the factory and should require no additional
adjustment. Do Not attempt to change engine speed. If
you believe the engine is running too fast or too slow,
take your unit to an authorized Sears service center for
repair and adjustment. CHANGING THE ENGINE
GOVERNED SPEED WILL VOID THE ENGINE
WARRANTY.
Do Not try to adjust the governed speed for the
following reasons:
•
Operating the engine at high engine speeds is
dangerous and increases the risk of personal injury
or damage to the equipment.
•
Operating the engine at low engine speeds with
heavy loads may shorten the engine's life.
Incorrect speed settings also affects electrical
operation of your generator as follows:
•
Operating at high speeds results in an over-
frequency and over-voltage condition.
•
Operating at low speeds causes an under-
frequency and under-voltage condition.
IMPORTANT:
Incorrect frequency and/or voltage
may damage some connected electrical loads.
If you suspect engine speed is incorrect,
take the
unit to an authorized
Sears service
facility for
repair and adjustment.
Carburetor
Adjustments
The engine carburetor is preset at the factory. The
carburetor should not be tampered with because doing
so will void the emission control system warranty. If
you experience problems or your engine is used at an
altitude higher than 5,000 feet, contact the nearest
authorized Sears service center regarding high altitude
setting changes.
