Bessertrim Grass Cutting System User manual

WARNING &
SAFETY
INSTRUCTIONS
These warning and safety instructions
for the Bessertrim Grass Cutting
System are not a replacement for the
manual for your grass trimmer / brush
cutter unit. At all times, you must read
these warning and safety instructions
in conjunction with the manual for
your grass trimmer / brush cutter unit
and follow all warnings and safety
instructions therein. Failure to do so
can result in serious or fatal injury to
the operator and / or bystanders.
PHYSICAL CONDITION
OF OPERATOR
Do not operate your grass trimmer /
brush cutter unit when tired, ill or
under the influence of alcohol, drugs
or medication. If you get tired, take a
break.
EYE
PROTECTION
Wear eye protection that complies
with ANSI Z87.1 (or your equivalent
national standard). In addition, to
further reduce the risk of injury, we
recommend that the operator wears a
face shield.
CLOTHING &
FOOTWEAR
A cutting attachment shield (guard)
may not fully protect the operator
against thrown objections and
especially ricochets. Always wear
heavy, long pants, boots, gloves, and
a long-sleeve shirt. Do not wear loose
clothing, jewellery, short pants,
sandals or go barefoot. Secure hair
so it is above shoulder level.
HEARING
PROTECTION
Observe labelling on your grass
trimmer / brush cutter unit requiring
operator hearing protection.
CONDITION OF UNIT
BEFORE USE
Inspect unit before each use as
specified in the manual for your grass
trimmer / brush cutter unit. Replace
damaged parts. Check for fuel leaks.
Make sure all fasteners are in place
and secure. Retighten all accessible
screws and nuts if required. For units
equipped with a clutch, ensure that
the cutting attachment stops turning
when the engine idles. Do not use
your unit otherwise. For directions on
how to adjust idle speed, refer to your
grass trimmer / brush cutter unit’s
operating manual and / or dealer.
CONDITION OF CUTTER
HEAD BEFORE USE
Replace the cutter head if cracked,
chipped or damaged in any way.
Never try to repair the cutter head by
welding, straightening or modifying its
shape. Make sure the cutter head and
cutters are properly installed and
securely fastened in accordance with
the assembly instructions contained
herein. Be sure the cutting attachment
shield is properly attached and in the
position recommended by the
manufacturer.
PROPER
USE
Only use your grass trimmer / brush
cutter unit as specified in the manual
for your grass trimmer / brush cutter
unit.
Never use your grass trimmer / brush
cutter unit with a loose cutting
attachment. Check the condition of
the cutting assembly at regular
intervals including that the cutting
assembly fixings are properly
tightened. If the cutting assembly
starts to behave differently, e.g. by
vibrating excessively or becomes
clogged with debris, cease use
immediately and wait for the cutting
assembly to stop; then check the
condition of the unit and / or clean the
cutting head.
Use only cutters recommended by
Bessertrim. Never use, for example,
wire or wire-rope, which can break off
and become a dangerous projectile.
Loss of control of your grass trimmer /
brush cutter unit may result in serious
or fatal injury to the operator and
bystanders. Ensure the proper use
and positioning of your hands, feet,
any handlebar(s), any harness(es),
and the unit as specified in the
manual for your grass trimmer / brush
cutter unit. Keep firm footing and
balance. Do not over-reach. Keep the
cutting assembly below waist level, if
possible at ground level and parallel
to the ground. Keep all parts of your
body away from the cutting assembly.
Take special care in difficult
conditions such as whilst working on
slippery, uneven or sloping terrain.
Never leave your grass trimmer /
brush cutter unit unattended. Do not
lend or rent your grass trimmer /
brush cutter unit without the
instruction manual for your grass
trimmer / brush cutter unit and these
Warning and Safety Instructions.
KICK
OUT
Kick out (akin to ‘blade thrust’) may
occur when the spinning cutting
attachment contacts an object that it
does not immediately cut.
WORK
AREA
Clear the area to be cut before each
use. Remove all objects such as
stones, rocks, broken glass, nails,
wire or string, which can be thrown,
ricochet or become entangled. Clear
the area of children, bystanders and
pets. At a minimum, keep all children,
bystanders and pets outside a 50 ft
(15 m) radius; outside the 50 ft zone,
there is still a risk of injury or damage
to property (such as vehicles and
windows) from thrown objects.
Bystanders should be encouraged to
wear eye protection. If you are
approached, stop the engine and the

cutting assembly. There is the added
risk of injury to bystanders from being
struck with the cutting assembly in the
event of kick out (akin to ‘blade
thrust’) or other unexpected reaction
of your grass trimmer / brush cutter
unit.
Use of your grass trimmer / brush
cutter unit is not recommended in
areas containing a lot of stone or
gravel.
Use of your grass trimmer / brush
cutter unit may cause dust to be
thrown up which may be inhaled by
the operator or bystanders causing
respiratory problems. This may
include chemicals such as pesticides
or herbicides used to treat the
vegetation. Where possible, your
grass trimmer / brush cutter unit
should be operated so that any
prevailing wind directs any dust away
from the operator and bystanders. In
certain circumstances, use of a mask
or respirator by the operator and
bystanders may be advisable.
TRANSPORTATION AND
STORAGE OF THE UNIT
Note that the cutting attachment may
continue to rotate after the throttle is
released and / or unit turned off. Make
sure the cutting attachment has
stopped before the unit is set down.
Do not transport your machine when
the engine is running or the cutting
attachment is moving.
LOADING INSTRUCTIONS
Push the cutter, small end first, into
the loading slot so it moves between
top and bottom flange on the cutter
head (inside to out). Pull it through
until the ‘ball’ locates into the loading
slot. Once in place, check the cutter
swivels freely.
NUMBER AND SIZE OF CUTTERS
Begin by using two cutters and only
increase to four if your engine allows.
Listen to your engine, if it seems to
labour whilst using four cutting lines it
is likely that the cutter size being used
is too large.
UNLOADING INSTRUCTIONS
To replace the old nylon cutter, push
the ball end downwards or upwards
out of the loading slot by using the
ball end of the replacement cutter,
then pull the old cutter out.
‘DECIMATOR’ CUTTERS
A heavy duty, cable reinforced Nylon
cutter for the toughest environments.
Only suitable for machines with a
cutting radius of 200+ mm. For use
with BTHD1.
WEAR OF THE
‘DECIMATOR’ CUTTERS
‘Decimator’ cutters will wear during
normal use whereby the Nylon in the
cutting zone (the last 15mm to 25mm)
wears away and the underlying cable
starts to fray. Thereafter, the cable
wears away and the cutter shortens.
Replace the cutter if the wear pattern
deviates from this or the Nylon
becomes completely worn away.
During use, grooves will naturally form
in the ball of the cutter.
