stick. If oil level is near or below the lower limit, oil must
be added. (See figure 4)
5. Add oil slowly until the oil level reaches the upper limit of
the dipstick. Use a funnel or nozzle to reduce spillage.
Frequentlycheckoillevelwhilefilling.DONOTOVER-
FILL.DONOTUNDERFILL.Runningengineatimproper

TRIMMING TIPS
Debris such as sticks, gravel, and rocks can be thrown with
sufcientforcetocausepersonalinjuryorpropertydamage.
• Frequentlycleandebrisandgrassbuildupfromthe 
recoil starter cover holes, under the deck in the trimming
 headarea,andaroundthemufer.Usingtheunitwith
 excessivedebriscanriskre.Alwaysuseextreme 
caution when using the trimmer during dry conditions.
• Ifthetrimmerlinesbecometooshort,itwilltakelonger
to complete this job. If the trimmer lines are worn to less
than half their original length, change to a new trimmer
 line.See“HowtoReplacetheTrimmerLine”inthe 
Maintenance section.
• Donottrimonexcessivelysteepslopes.SeeSlope 
 Guide.Ifaslopeisdifculttostandon,donottrimit.Do
not trim on slopes when the ground is slippery or wet.
Trim across the face of a slope, not up and down.
• Trimmerheadcontacttoconcrete,asphaltandharder
surfaces may create premature wear to the height guide.
• Forbestresultsandlongerlastingline,soakthetrimmer
line in a pale of water for 24 hours prior to use. A moist
 linewillbemoreexiblethanadry,brittleline.
• Lettheendsofthetrimminglinedothecutting.Thisis
easily done by moving slowly through very thick or heavy
weeds.
SLOPE GUIDE SIGHTANDHOLDTHISGUIDELEVELWITHAVERTICALTREE,A CORNEROFASTRUCTURE,APOWERLINEPOLE,ORAFENCE. Operate a trimmer across the face of slopes, never up or down slopes. Use this guide and do not trim on a slope greater than 15 degrees. A 10-degree slope is a hill that increases in height at approximately 1.7 feet in 10 feet. A 15-degree slope is a hill that increases in height at approximately 2.5 feet in 10 feet.
WARNING! Use extreme care at all times and avoid sudden turns or maneuvers. Follow other instructions in this manual for safety in trimming on slopes. Operate a trimmer across the face of slopes, never up or down slopes. Use extra care when operating on or near slopes and obstructions.

How to Check the Spark Plug
Maintenance (Continued)
• Save all instructions
Spark Plug Model: Torch F6RTC
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. Remove the spark plug with a 13/16 in. (21 mm) deep
well socket.
4. Visually inspect the spark plug for cracks or damage. If
cracked, replace spark plug.
5. Clean carbon deposits. If excessive carbon build up, re
place spark plug.
6. Check that the gap of the spark plug is 0.028-0.031 in.
(0.7-0.8 mm). (Figure 18)
7. Re-insert the spark plug and tighten to 18-22 foot-pounds
 (25-30Nm).
8. Reattach spark plug wire to spark plug.

How to Replace the Trimmer Lines
Maintenance (Continued)
• Save all instructions
When the trimmer line becomes worn to half the original
length, replace the trimmer line. For the best performance,
use a heavy gauge 0.155 in. [4 mm] trimmer line.
1. Stop the engine. Wait for all moving parts to stop.
Disconnect the wire from the spark plug.
2. Remove the worn trimmer line from line retainer.
3. Cut the length of the trimmer line to 21.5 in. [546 mm].
 Usethelengthguide;locatedontheshieldtomakesure
the trimmer line is the correct length. (See Figure 14)
NOTE: Do not allow the length of the lines to vary more than
one inch. Make sure the trimmer head is balanced and does
not vibrate.
4. Thread the ends of the new trimmer line through the
outside loops. (See Figure 15)
5. Take the ends of the line, cross over the line retainer,
and thread the ends through the center hole.
(See Figure 16)
6. Then, check to make sure that the ends of the line are
even. (See Figure 17)
7. Follow same steps for line on alternate side.
IMPORTANT: To extend the life of the trimmer line, keep the
trimmer line moist. If not kept moist, the nylon trimmer line
will become dry and brittle. Keep extra trimmer line in a can
ofwater.Thelinewillthenstayexibleandeasytochange.
Aexiblelinewillalsolastmuchlonger.

Neverstorethetrimmerindoorswithfuelinthefueltank.
Neverstoreinanenclosed,poorlyventilatedareawhere
fumescouldreachanopename,asparkorapilotlightas
on a furnace, water heater or clothes dryer. Allow engine to
cool before storing unit.

orwhileyousmoke.Gasolinefumescancauseanexplo-
sionorare.
NOTE: A yearly checkup or tune-up at an authorized service
center will make sure that the trimmer will provide maximum
performance for the next season.
When the trimmer is put in storage for thirty days or more,
the following steps should be followed to make sure the
Trimmer 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 Engine Oil” section.
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
spark plug in the cylinder. Pull recoil slowly until
resistance is felt. This will close the cylinder valves.
