Above images illustrate how to use quick release mechanism
engine. Support the machine with your left hand and operate
the quick-release mechanism. Be aware that the machine will
fall and a rotating blade or nylon trimmer can cause death or
severe injury.
WARNING
- Be careful not to accidentally operate the quickrelease
on the harness. Be aware that the machine will
fall and that a rotating blade or nylon trimmer can cause
death or severe injury.
CUTTING USING THE METAL BLADE
(1) For shrubs & thick weeds
(2) For grass and weeds
(3) Direction of cutting
(4) Direction of rotation
1. A metal blade cuts best with a swathe up to one third of the
cutter diameter. Use that area for cutting shrubs, tough and
thick weeds. For cutting young grass, you can use up to two
thirds of the cutter diameter.
2. Adjust the engine speed according to the material being cut.
Cut the young grass at middle speed, and shrubs or tough and
thick weeds at high speed.
If the cutting speed is too low, debris can be caught up
in the blade, and if this causes the clutch to slip it will
wear out quickly.
CUTTING WITH THE NYLON CUTTER
• Cutting with the nylon cord consumes more power so
the engine speed should be 50% greater than when
using the metal blade.
• The nylon cord cuts the grass by meeting it at high speed. If
you take too wide a swathe you may slow down the engine
and not get clean cutting. To correct this, retract the cutter from
the grass until the engine regains full speed and then cut using
a narrower swathe.
• After a time the nylon cord will wear away. To restore the
full cutting diameter, simply bump the cutter head on the
ground while it is running at full speed. The cords will extend
automatically and will be trimmed to the correct length by the
cord trimmer blade mounted on the guard.
• Cut grass by swinging the brushcutter from right to left
with the BC 230B S2 and BC 260B S2 models, and left
to right with the BC 260 S2 and BC 325 S2 models. While
you can cut in either direction, if you follow these suggestions
the cut grass will be thrown away from you, and you will avoid
getting your clothes dirty.
Maintenance
BLADE
• Sharpen each cutting edge and make sure the inside corner is
rounded to reduce the risk of cracking.
• Do not quench the blade with water if you are using a grinder
as it may start cracks in the blade.
• The 3 tooth blade on the BC 260 S2
and the BC 325 S2 may be inverted to
utilise a fresh set of cutting edges.
NYLON CUTTERS
The spools of nylon cord inside these bump-feed cutter heads will
eventually need replacing. While the change can be made with the
cutter head on the machine, it will be more convenient to remove
the cutter head.
BC 230B S2 and BC 260B S2.
Fit a spanner to the hexagon and unscrew the head (turn
anti-clockwise). Unscrew the bump cylinder from the head
(anti-clockwise). It may be necessary to turn the spool slightly to
free it from the housing. Do not lose the spring beneath the spool.
Feed the ends of the cords through the holes in the sides of the
head before fitting the replacement spool. Re-fit the bump cylinder
and re-mount the head on the spindle.
BC 260 S2.
Lock the spindle with the L shaped bar through the hole in the
outer shroud into the hole in the inner flange and unscrew the cutter
head by turning clockwise (LEFT HAND THREAD). The cover on
the bottom of the housing can be removed by squeezing inwards
(or prying with a screwdriver) on opposite sides of the housing skirt
at points below the ‘PUSH TO OPEN’ markings on the top of the
housing. The spool can then be removed from the housing. Do not
lose the spring behind the spool.
When fitting the replacement nylon, run the nylon from the inner half
of the spool through the small notch in the rim and feed the ends
of the cords through the holes in the housing skirt before sliding the
spool into the housing. The bottom cover will snap into place only
when it is turned to the correct position relative to the housing.
Note: both nylon cords need to be wound in the
same direction.
