How to Check the Spark Plug
G
Spark Plug Model: Torch F7RTC
Only use the recommended spark plug or a spark plug with
the same temperature range. Using an improper spark
plug, an incorrect spark plug gap, or a dirty/fouled spark
plug can reduce engine performance and cause damage.
1. Stop engine and allow it to cool.
2. Remove spark plug wire from spark plug.
3. Use the spark plug wrench and rod (included with edger)
to remove the spark plug. (See Figure 15)
4. Visually inspect the spark plug for cracks or damage. If
cracked, replace spark plug.
5. Clean carbon deposits. If excessive carbon build up,
replace spark plug.
6. Check that the gap of the spark plug is 0.028-0.031 in.
(0.7-0.8 mm). (See Figure 16)
7. Re-insert the spark plug and tighten using the spark
plug wrench and rod. (See Figure 15)
NOTE:
Torque of spark plug is 18-22 foot-pounds (25-30 Nm)
8. Reattach spark plug wire to spark plug.
How to Clean the Air Filter
F
A dirty air filter will restrict air intake. Regular maintenance
of air cleaner will help improve engine performance and
reduce emissions.
Never clean air filter with gasoline or an easy ignited sol-
vent because it may cause explosion.
IMPORTANT:
Only use replacement air filter from the manu-
facturer. To order spare parts call us at 1-800-737-2112
NOTE:
Refer to Figure 14 when following steps below:
1. Remove the outer wing nut, washer, and air filter cover.
2. Remove the inner wing nut, and the air filter.
IMPORTANT:
Use care when removing the air filter so dirt and
debris does not fall into the carburetor.
NOTE:
Air filter is made up of an outer foam element and an
inner paper element.
3. Separate the outer foam element from the inner paper
element.
4. Check the inside of the paper element for dirt or debris.
5. Check both elements for tears.
NOTE:
If the inner paper element is dirty or if either element is
torn, replace with a new air filter from the manufacturer.
6. Clean the outer foam element by washing it thoroughly in
a solution of household detergent and water, or in a
nonflammable or high flash point solvent. Allow to
dry thoroughly. Then soak the foam element in clean
engine oil, and squeeze out all excess oil.
7. Clean the inner paper element by lightly tapping it
against a hard surface to remove excess dirt or by
blowing compressed air through the filter from the
inside out.
IMPORTANT:
Do not attempt to brush dirt off the paper ele-
ment, as this will only embed dirt into the fibers.
8. Reinstall the cleaned out foam element onto the inner
paper element.
9. Reinstall the clean air filter and cover onto the unit by
reversing steps 1 and 2 above.

How to Prepare for Storage
H
Never store the edger indoors with fuel in the fuel tank. Never store in an enclosed, poorly ventilated area where fumes
could reach an open flame, a spark or a pilot light as on a furnace, water heater or clothes dryer. Allow engine to cool
before storing unit.
Do not remove gasoline while inside a building, near a fire, or while you smoke. Gasoline fumes can cause an explosion
or a fire
.
NOTE:
A yearly checkup or tune-up at an authorized service center will make sure that the edger will provide maximum
performance for the next season.
When the edger is put in storage for thirty days or more, the following steps should be followed to make sure the edger is in good
condition the next season.
1. Let the engine run until it is out of gasoline.
2. Change the oil by following
instructions under “How to Change the Oil.”
3. Remove the spark plug from the cylinder. Pour one ounce of oil into the cylinder. Slowly pull the recoil-start grip so
that the oil will protect the cylinder. Install a new spark plug in the cylinder. Pull starter handle slowly a few times to
distribute oil. Pull recoil slowly until resistance is felt. This will close the cylinder valves.
DO NOT attach spark plug wire to spark plug when storing unit.
4. Clean edger. Remove all dirt, leaves, debris, grease, etc. from the edger - including cylinder cooling fans, recoil starter
cover holes, under fuel tank, and under muffler.
5. Check the edger for worn or damaged parts. Have damaged parts replaced if necessary.
6. Tighten any loose hardware.
7. Apply lubrication as directed in Maintenance section.
8. Put the unit in a building that has good ventilation.
9. Cover the edger with a breathing material.
