6-1. ADDITIONAL SAFETY PRECAUTIONS

Before operating your unit, review ALL SAFETY PRECAU-
TIONS in this manual.
WARNING / CAUTION
• IF UNFAMILIAR WITH TRIMMING techniques, prac-
tice the procedures with ENGINE in "OFF" position.
• ALWAYS CLEAR WORK area of debris such as cans,
bottles, rocks, etc. Striking objects can cause serious
injury to operator or bystanders and also damage
equipment. If an object is accidentally hit, immediately
TURN ENGINE OFF and examine equipment. Never
operate unit with damaged or defective equipment.
• ALWAYS TRIM OR CUT AT HIGH ENGINE SPEEDS.
Do not run engine slowly at start or during trimming
operations.
• DO NOT use equipment for purposes other than trim-
ming or mowing weeds.
• NEVER raise stringhead above knee height during
operation.
• DO NOT operate unit with other people or animals in
the immediate vicinity. Allow a minimum of 50 feet (15
meters) between operator and other people and ani-
mals when trimming or mowing. Allow a distance of
100 feet (30 meters) between operator and other peo-
ple and animals when SCALPING with stringhead cut-
ter.
• IF OPERATING UNIT ON A SLOPE, stand below the
cutting attachment. DO NOT OPERATE on a slope or
hilly incline if there is the slightest chance of slipping
or losing your footing.

6-2. STRINGHEAD LINE RELEASE

WARNING / CAUTION
DO NOT use steel wire or plastic-coated steel wire of any
kind with your stringhead. Serious operator injury can
result.
To release fresh line, run engine at full throttle and "bump"
stringhead against lawn. Line will automatically release.
The knife in debris shield will trim excess line (Figure 6-2A).
CAUTION
Be sure engine is off and string head has stopped before
attempting to remove weeds wrapped around the shaft.
Periodically weeds will wrap around the shaft. They will
need to be removed or they will prevent the shaft from
being properly cooled and could result in damage. Use a
sharp object like a screw driver to remove them. (Fig. 6-2B)

6-3. TRIMMING PROCEDURES

When properly equipped with a debris shield and string-
head, your unit will trim weeds and tall grass in those hard-
to-reach areas - along fences, walls, foundations and
around trees. It can also be used for scalping to remove
vegetation down to the ground for easier preparation of a
garden or to clean out a particular area.
NOTE: Trimming around foundations, brick or stone walls,
curves, etc., will result in above normal string wear.
TRIMMING / MOWING
Swing trimmer from side to side. Do not tilt the stringhead
during the procedure. Test area to be trimmed for proper
cutting height. Keep stringhead at same level for even
depth of cut (Figure 6-3A).
