How to Check the Spark Plug

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

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.
