you begin any maintenance or repairs. Ensure
the cutting attachments stop. This will help to
eliminate several potential hazards:
• Your engines exhaust contains poisonous carbon
monoxide gas, which can collect rapidly in an
enclosed area and cause illness or death.
• Be sure there is adequate ventilation wherever
you operate the engine.
• Burns from hot parts. Avoid contact with
exhaust; a hot exhaust can cause serious
burns!
• Let the engine and exhaust system cool before
touching.
• Injury from moving parts – be aware of moving
parts.
• Do not run the engine unless instructed to do so.
2) Read ALL instructions before you use this
appliance.
3) To reduce the possibility of fire or explosions,
be careful when working with petrol. Use only a
nonflammable solvent, not petrol, to clean parts.
4) Keep cigarettes, sparks, and flames away from all
fuel-related parts.
3. SPARk PLuG
The spark plug must be cleaned or replaced every
20hours to ensure proper performance of your
product.
1) Remove the spark plug cover by pulling it away
from the spark plug. (See fig. T1)
2) Remove the spark plug from the engine by
rotating anti-clockwise with the socket spanner
provided (See Fig T2)
3) Follow these cleaning instructions: (See Fig T3)
• Spray the spark plug with a quality carbon
cleaner.
• Gently clean using a wire brush.
• Install the new or cleaned spark plug with
0.5~0.7mm electrode gap and reassemble
completely before use.
This engine uses a L6RTC with 0.5-0.7 mm electrode
gaps (Or Champion: RCJ6Y,CJ7Y, RCJ7Y, RCJ8,
RCJ8Y or NGK: BM6A, BMR6A, BPMR6A).
Use a suitable replacement and replace once a year.
4. AIR fILTER CLEANING
A dirty air filter will restrict airflow to the carburetor,
reducing engine performance.
If you operate the engine in very dusty areas, clean
the air filter frequently.
Press the button on the air filter and then pull off the
air filter cover. (See Fig. U) Clean the filter in the oil.
When filling the filter cover, put the choke lever to the
middle position.
5. CuTTING-LINE hEAd
The cutting-line head containing nylon monofilament
line, a guard and a cutoff knife is standard
equipment. The guard’s cutoff knife automatically
removes any excess line that is released from the
cutting head. A protective cover is used over the
cutoff knife. Remove this protective cover before
operating. (See Fig. V)
Nylon monofilament line is suitable for cutting grass
and ordinary weeds, but not for cutting brush and
woody growth.
6. ExTRACTION Of NyLON LINE
The nylon line can be cut off by debris or by coming
into contact with solid parts, on these occasions
follow this procedure to extend the cutting line.
1) Stop the engine and wait until the spool has
stopped.
Push rim of coil, turn it a little to the left, then to the
right.
2) Pull out both nylon lines until the line is long
enough to be cut off by the line cutting blade.
7. REPLACING NyLON LINE
Note: Stop the engine and wait until the spool has
stopped.
1) Clean any mud, dirt, debris, etc, from the area
around the trimmer head; otherwise, it will make
it more difficult to service.
2) Remove bump head knob by turning anti-
clockwise. Remove the spool and spring from
spindle. (See Fig.W)
3) Measure approximately 6 meters of line, and then
thread one end through the hole on the spool.
Pull the line until the two line lengths are equal
(See Fig. X).
4) Wind both lines tightly and evenly from side to
side and feed the line while turning the spool in
the direction of the arrow - winding clockwise. Do
not allow the lines to become twisted (See Fig. Y).
It is important to prevent the two lines from
becoming twisted with each other. Position a finger
between the lines as you turn the spool to prevent
any twisting.
5) When you have about 6 inches (150mm) of line
remaining, press the line into the two notches on
the bottom of the spool. This will hold the line on
