Maintaining the Trimming Line
Hard surfaces, such as sidewalks, can cause the trimming
line to wear down quickly or break.
• Frequently check the trimming line length. Replace the
trimming line as needed. Refer to Replacing the Trimming
Line.
• Do not force the unit. Make shallow cuts in as many
passes as are necessary to achieve the desired depth.
Cut at a slow, even pace.
CUTTING TIPS
• Always wear eye protection with side shields marked to
comply with ANSI Z87.1, along with hearing protection.
Failure to do so could result in objects being thrown into
your eyes and other possible serious injuries.
• Operate this unit only in a well-ventilated outdoor area.
Carbon monoxide exhaust fumes can be lethal in a
conned area. Do not operate the unit inside a closed
environment, such as a room or building; breathing
carbon monoxide from exhaust fumes can kill.
• Clear the area to be cut before each use. Remove all
objects such as rocks, broken glass, nails, wire, or string
which can be thrown or become entangled in the cutting
attachment. Clear the area of children, bystanders, and
pets outside a 50 ft (15 m) radius.
• Avoid hot surfaces by always keeping the tool away from
your body.
• Cut all grass from top to down. This will prevent grass
from wrapping around the shaft housing and string head
which could cause damage from overheating.
• The preferred direction of trimmer operation is from left
to right .
• If grass becomes wrapped around the string head, stop
the engine, disconnect the spark plug wire, and remove
the grass.
• Use the tip of line to trim grass; do not force string head
into uncut grass.
• Avoid trees, owers, stones, walls and other objects which
can cause the line to break.
• Check and feed the line regularly to maintain full cutting
width and performance.
• Operation of this equipment could create sparks that
can start res around dry vegetation. A spark arrestor
may be required. The operator should contact local re
agencies for laws or regulations relating to re prevention
requirements.
TIPS FOR BEST RESULTS
• To direct clippings away from the operator, tilt the cutting
head slightly down to the right; whenever possible swing
the trimmer in a left to right cutting motion.
• Do not trim wet grass or weeds.
Some line breakage will occur from:
• Entanglement with foreign matter
• Normal line fatigue
• Attempting to cut thick vegetation
• Forcing the line into objects such as walls or fence posts
MAINTENANCE
To avoid serious personal injury, always stop the engine
and allow it to cool before cleaning or maintaining the unit.
Never perform cleaning or maintenance while the unit is
running. Disconnect the spark plug wire to prevent the unit
from starting accidentally.
Wear protective clothing and observe all safety instructions
to prevent serious personal injury.
Do not use any attachments or accessories not
recommended by the manufacturer of this product. Never
use metal-reinforced line, wire, chain or rope. These can
break off and become dangerous projectiles. Only use the
trimming line described in the specications section.Other
types of trimming line may cause the unit to overheat or fail.
REPLACING THE SPOOL
1. Push in the tabs on the side of the spool retainer and
pull to remove (Fig. 17).
2. Install the spring, washer, and rewound spool, making
sure that the lines are captured in the holding slots on
the new spool.
NOTE:
Make sure that the ends of the lines extend approximately
6 in. (152 mm).
3. Install the new spool so that the line ends align with the
eyelets in the cutting head, and thread the line ends
through the eyelets.
4. Pull the lines extending from the cutting head so that the
strings release from the slots in the spool.
5. Install the spool retainer by pressing the tabs into the
slots and pushing down on the spool until the spool
retainer clicks into place (Fig. 17).
REPLACING THE TRIMMING LINE
1. Remove the spool from the cutting head.
2. Remove any old line from the spool. Use a clean cloth
to clean the surface of the cutting head.
3. Cut a 15 ft. (4.5 m) length of 0.095 in. (2.4 mm) diameter
trimming line.
4. Bend the line at the midpoint and insert the bend into
the holding slot on the spool (Fig. 18).
