• 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
trimming or mowing weeds.
• NEVER raise cutting head 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
animals when trimming or mowing.
• Allowadistance of 100 feet (30 meters) between
operator and other people and animals when
SCALPING with cutting head cutter.
• 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.
• CUTTING HEAD LINE RELEASE
To release fresh line, run engine at full throttle and “bump”
cutting head against lawn. Line will automatically release.
The knife in the cutting attachment guard will trim excess
line (Fig.11A).
• TRIMMING PROCEDURES
When properly equipped with a cutting attachment guard
and cutting head, your unit will trim unsightly weeds and
tall grass in those hard-to-reach areas - along fences,
walls, foundations andaround trees.It can alsobe used for
scalping to remove vegetation down to the ground for eas-
ier preparation ofagarden or to cleanoutaparti
cular area.
NOTE: Even withcare, trimming around foundations, brick
or stone walls, curves, etc., will result in above normal
string wear.
TRIMMING / MOWING
Swing trimmer withasickle-like motion from side to side.
Do not tilt the cutting head during the procedure.Test area
to be trimmed for proper cutting height.Keep cutting head
at same level for even depth of cut (Fig. 12A).

TRIMMER INSTRUCTIONS
WARNING: DO NOT use steel wire or plas-
tic-coated steelwire of any kind with your cut-
ting head. Serious operator injury can result.
CAUTION: Periodically remove weed wrap to
prevent overheating the drive shaft. Weed
wrap occurs when strands of weeds become
entangled around the shaft beneath the cut-
ting attachment guard (Fig. 11B).This condi-
tion prevents the shaft from being properly
cooled. Remove weed wrap with screwdriver
or similar device.

CLOSERTRIMMING
Position trimmer straight ahead with a slight tilt so bottom
of cutting head is above ground level and string contact
occurs at proper cutting point.Always cut away from oper-
ator. Do not pull trimmer toward operator.
FENCE/FOUNDATIONTRIMMING
Approach trimming around chain link fences, picket
fences, rock walls and foundations slowly to cut close
without whipping string against the barrier. If the string
comes in contact with rock, brick walls, or foundations, it
will break or fray. If string snags fencing, it will snap off.
TRIMMING AROUNDTREES
Trim around tree trunks withaslow approach so string
does not contact bark.Walk around the tree trimming from
left to right. Approach grass or weeds with the tip of the
string and tilt cutting head slightly forward.
SCALPING
Scalping refers to removal of all vegetation down to the
ground. To do this, tilt the cutting head to about a 30
degree angle to the right. By adjusting the handle you will
have better control during this operation. Do not attempt
this procedure if there is any chance flying debris could
injure operator, other people or cause damage to proper-
ty (Fig. 12B).
DO NOT SWEEP WITH TRIMMER
Sweeping refers to tilting cutting head to sweep away
debris from walkways, etc.Your trimmer i
sapowerful tool
and small stones or other such debris may be hurled 50
feet (15 meters) or more, causing injury or damage to
nearby property such as automobiles, homes and win-
dows.
• CUTTING WITH BLADES
Always wear eye protection and protective clothing when
cutting withablade.
Always use the harness for blade operations.
• USING WEED BLADES
SCYTHING WEEDS
Scything refers to cutting by moving the blade from side to
side inalevel arc. It is most effective with grassy weeds
and light undergrowth. It should not be used to cut
large,
tough weeds or woody growth (Fig. 13).
• USING A BRUSH BLADE
SCYTHING
Scything may be used with a brush blade for light brush
and undergrowth.It is not recommended for tough growth.
BINDING
Top heavy growth such as saplings and heavy brush can
bind and stop the blade. Avoid binding by anticipating
which way the growth will lean, and cut from the opposite
side.
If the blade binds in a cut stop the engine immediately.
Hold the unit up to prevent the blade from cracking or
breaking while pushing the sapling away from the cut to
free the blade.
AVOID KICKOUT
Kickout is the reaction ofamoving blade if it contacts a
strong tree, brush orasolid object. The force that occurs
violently pushes the blade away in an arc. Kickout could
cause loss of control resulting in injury to the operator or
bystanders.
DO NOT USEABLADE NEAR A CHAIN LINK FENCE,
METAL STAKES, LANDSCAPE BORDERS OR BUILD-
ING FOUN
DATIONS.
The Partner
blade guard is designed to reduce the risk of
kickout by providing stops to brace the unit against the
object being cut.
Place the sapling against the stop (A) so the rotation of
the blade continually draws it into the stop (A) (Fig. 14).
WARNING: Use extreme caution when
SCALPING. Keepadistance of 50 feet (15
meters) between operator, other people and
animals during these operations.
