“bump” stringhead against lawn. Line will
automatically release. The knife in debris shield will
trim excess line (Fig. 9A).
CAUTION: Periodically remove weed wrap to
prevent overheating the drive shaft. Weed wrap
occurs when strands of weed become entangled
around the shaft beneath the debris shield (Fig. 9B).
This condition prevents the shaft from being properly
cooled. Remove weed wrap with screwdriver or
similar
device.
• TRIMMING PROCEDURES
When properly equipped with a debris shield and
stringhead, your unit will trim unsightly 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: Even with care, trimming around foundations,
brick or stone walls, curves, etc., will result in above
normal string wear.
TRIMMING / MOWING
Swing trimmer with a sickle-like motion 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
(Fig. 10A).
CLOSER TRIMMING
Position trimmer straight ahead with a slight tilt so
bottom of stringhead is above ground level and string
contact occurs at proper cutting point. Always cut
away from operator. Do not pull trimmer in toward
operator.
FENCE / FOUNDATION TRIMMING
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 AROUND TREES
Trim around tree trunks with a slow 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 stringhead slightly
forward.
WARNING: Use extreme caution when
SCALPING. Keep a distance of 100 feet (30 meters)
between operator, other people and animals during
these operations.
SCALPING
Scalping refers to removal of all vegetation down to
the ground. To do this, tilt the stringhead to about a
30 degree angle to the left. 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 property. (Fig. 10B)
Cutting with blades
WARNING: Before you use this machine with a
blade, check that it has been fitted correctly. Follow
all the instructions set out in the section entitled
“Safety instructions for undergrowth/grass cutting
blades” in this operating manual.
CUTTING WITH BLADES
Whenever you are cutting with a blade you must
wear eye protection and protective clothing. Always
use the shoulder strap when working with the blade.
WORKING WITH WEED-CUTTING BLADES
(supplied, Art. No. 34.051.63)
MOWING WEEDS
Mowing means moving the blade in a horizontal
curve from one side to the other. This is very
effective for grass-like weeds and small undergrowth.
It is not suitable for cutting large, tough weeds or
woody vegetation (Fig. 11).
CAUTION: Do not use weed-cutting blades for
cutting scrub or young trees.
SAWING
The BMST 24 is not designed for sawing.
JAMMING
Very thick vegetation, such as young trees or thick
scrub may jam the blade and bring it to a standstill.
Prevent the blade from jamming by anticipating the
direction in which the scrub leans and cut it from the
opposite side.
If the blade jams while cutting, switch off the engine
immediately. Hold the machine level so that the
blade does not jump or break while you push the
young tree away from the cut to free the blade.
TO PREVENT RECOIL
When using metal cutting tools (grass blades, thicket
knives) there is a risk that the machine will recoil if
the tool strikes a solid object (tree truck, branch, tree
stump, stone or the like). In this case the machine
will jump backwards in the opposite direction to
which the tool is rotating. This may lead to a loss of
control of the tool and risk of injury to the user and
onlookers.
