How to Check the Spark Plug
Spark Plug Model: Torch F7RTC
CAUTION
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 blower)
to remove the spark plug. (See Figure 13)
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 14)
7. Re-insert the spark plug and tighten using the spark
plug wrench and rod. (See Figure 13)
NOTE: Torque of spark plug is 18-22 foot-pounds (25-30 Nm)
8. Reattach spark plug wire to spark plug.

How to Prepare for Storage
WARNING
Never store the blower 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.
WARNING
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 blower will provide maximum
performance for the next season.
When the blower is put in storage for thirty days or more, the following steps should be followed to make sure the blower 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.
WARNING
DO NOT attach spark plug wire to spark plug when storing unit.
4. Clean blower. Remove all dirt, leaves, debris, grease, etc. from the blower - including cylinder cooling fans, recoil
starter cover holes, under fuel tank, and under muffler.
5. Check the blower 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 blower with a breathing material.
