MIXING FUEL
Add oil to an approved fuel container followed by the
gasoline to allow incoming gasoline to mix with oil. Shake
container to ensure thorough mix.
WARNING:
Lack of lubrication voids engine war-
ranty. Fuel and oil must be mixed at 40:1.

RECOMMENDED FUELS
Some conventional gasolines are being blended with oxy-
genates such as alcohol or an ether compound to meet
clean air standards.Your Mcculloch engine is designed to
operate satisfactorily on any fuel intended for autom-
itive use including oxygenated fuels.
OPERATING INSTRUCTIONS
•
STARTING A COLD ENGINE
NOTE: To minimize load on engine during starting and
warm-up, trim excess line to 13cm (Fig. 4A).
1. Press ON/OFF Switch to the "RUN(I)" position (Fig. 4B)
2. Your unit is designed with a 3 position choke: FULL
CHOKE "
", HALF CHOKE "
", and RUN "
choke lever to FULL CHOKE "
" position, while the
throttle trigger is in full position (Fig. 4C).
3. Press the primer bulb (A) 10 times (Fig. 4D).
4. Wait 10 sec.
5. A smooth rapid pull is required for a strong spark. Pull
starter rope briskly maximum 6 times. (Fig. 4F) As soon
as the engine sounds as if it is trying to start (even if
less than 6 pulls) then move the choke lever to HALF
CHOKE "
" position.(Fig. 4G)
6. Pull starter rope again 4 times while trigger is in the full
throtthe posision (Fig. 4F).
7. Once engine is started, leave the choke lever in the
HALF CHOKE "
" position for 20 seconds, then move
choke lever to RUN "
". (Fig. 4H)
If engine does not start, go back to step 2.
NOTE: If engine fails to start after repeated attempts, refer
to Troubleshooting section.
NOTE: Always pull starter rope straight out. Pulling starter
at an angle will cause rope to rub against the eyelet. This
friction will cause the rope to fray and wear more quickly.
Always hold starter handle when rope retracts. Never
allow rope to snap back from extended position. This
could cause rope to snag or fray and also damage the
starter assembly.

WARM ENGINE START
1.
Move engine stopping denice to the "RUN" position
(Fig. 5A).
2.
Place choke in HALF CHOKE " " position (Fig. 5B).
3.
Grasp throttle handle firmly, squeeze throttle trigger
to FULL position.
4.
Pull starter rope briskly until engine starts, but no
more than 6 times. Keep throttle at FULL position until
engine runs smoothly.

5.
If engine does not start, place choke in RUN " " posi-
tion and pull starter rope 5 more times. If engine still
does not start it is probably flooded. Wait 5 minutes
and repeat procedure with choke in RUN " " position
and throttle full open.

ignition stop switch to stop the engine.

OPERATING INSTRUCTIONS
• OPERATING POSITION
ALWAYS WEAR:
Hearing
protection

Long pants
Heavy shoes
Cut from your right to your left.
Fig. 4F
WARNING: Always wear eye protection. Never
lean over the trimmer head. Rocks or debris
can ricochet or be thrown into eyes and face
and cause blindness or other serious injury.
Do not run the engine at a higher speed than necessary.
The cutting line will cut efficiently when the engine is run
at less than full throttle. At lower speeds, there is less
engine noise and vibration. The cutting line will last longer
Fig. 4H
and will be less likely to "weld" onto the spool.
Always release the throttle trigger and allow the engine to
return to idle speed when not cutting.
To stop engine:
• Release the throttle trigger.
• Push and release the engine ON/STOP switch.
TRIMMER LINE ADVANCE
The trimmer line will advance approximately 2 inches (5
cm) each time the bottom of the trimmer head is tapped
on the ground with the engine running at full throttle.
The most efficient line length is the maximum length
allowed by the line limiter.
Always keep the shield in place when the tool is being
operated.
To advance line:
• Operate the engine at full throttle.
• Hold the trimmer head parallel to and above the grasy
area.
• Tap the bottom of the trimmer head lightly on the
ground one time. Approximately 2 inches (5 cm) of line
will be advanced with each tap.
Always tap the trimmer head on a grassy area. Tapping
on surfaces such as concrete or asphalt can cause
excessive wear to the trimmer head.
If the line is worm down to 2 inches (5 cm) or less, more
than one tap will be required to obtain the most efficient
Fig. 5B
line length.
WARNING: Use only 0.080" (2 mm) diameter
line. Other sizes of line will not advance prop-
erly and can cause serious injury. Do not use
other materials such as wire, string rope, etc.
Wire can break off during cutting and become
a dangerous missile that can cause serious
injury.
CUTTING METHODS
WARNING: Use minimum speed and do not
Eye protection
crowd the line when cutting around hard objects
(rock, gravel, fence posts, etc.), which can
damage the trimmer head, become entangled
in the line, or be thrown causing a serious
hazard.
• The tip of the line does the cutting. You will achieve the
best performance and minimum line wear by not
crowding the line into the cutting area. The right and
wrong ways are shown below.
Tip of the line
does the cutting
Right
• The line will easily remove grass and weeds from
around walls, fences, trees and flower beds, but it also
can cut the tender bark of trees or shrubs and scar
fences.
• For trimming or scalping, use less than full throttle to
increase line life and decrease head wear, especially:
• During light duty cutting.
• Near objects around which the line can wrap such as
small posts, trees or fence wire.
• For mowing or sweeping, use full throttle for a good
chean job.
