Alpina TR 250 J, Operator'S Manual

Page: 30 / 358

For heavier cutting it can be useful to tilt the cutting
line head by about 30°.
Do not work in this way if
there is the possibility of causing objects to be
thrown, which could harm people and animals
and cause damage.
• Precision cutting (Trimming)
Keep the machine slightly tilted so that the lower
part of the cutting line head does not touch the
ground and the cutting line is at the required point,
always keeping the cutting device at a distance
from the operator.
• Cutting near fences/foundations (Fig. 9)
Slowly approach the cutting line head to fences,
posts, rocks, walls, etc. without hitting them hard.
If the line strikes a solid object it could break or be-
come worn; if it gets tangled in a fence it could
break abruptly.
In any case, cutting around pavements, founda-
tions, walls, etc. can cause greater wear than nor-
mal in the line.
• Cutting round trees (Fig. 10)
Walk round the tree from left to right, approaching
the trunks slowly so as not to strike the tree with the
line and keeping the cutting line head tilted for-
ward slightly.
Remember that the nylon line could lop or damage
small shrubs and that the impact of the nylon line
against the trunk of bushes or trees with soft bark
could seriously damage the plant.
• Adjusting line length when working
(Fig. 11)
This machine is fitted with a “Tap & Go” head.
To release more line, tap the cutting line head
against the round with the engine at top speed: the
line will be released automatically and the knife
cut off the excess length.
END OF OPERATIONS
When you have finished your work:
– Switch off the engine as indicated above (Chap.
6).
WARNING!
USING THE MACHINE
When working, the machi-
ne must always be firmly held in both hands,
keeping the power unit on the right of the body
and the cutting group below the line of the
belt.
Before tackling a mowing job for the first time it is
advisable to gain the necessary familiarity with the
machine and the most suitable cutting techniques,
finding out how to firmly grip the machine and mak-
ing the movements required by the job.
The cutting line head can eliminate tall grass and
non-woody vegetation near fences, walls, founda-
tions, pavements, around trees, etc. or to com-
pletely clean a particular area of the garden;
The use of metal or rigid
blades of any type with this machine is pro-
hibited.
WORKING TECHNIQUES
Use ONLY nylon lines. The
use of metal lines, plasticised metal lines an-
d/or lines not suitable for the head can cause
serious injuries and wounds.
During use it is advisable to stop the engine peri-
odically and remove the weeds wound round the
machine, so as to prevent the drive tube from over-
heating due to the grass caught under the guard.
Remove the caught-up grass with a screwdriver to
allow the rod to be properly cooled.
Do not use the machine
for sweeping, tilting the cutting line head. The
power of the engine could throw objects and
small stones 15 metres or more, causing dam-
age and injuries to people.
• Cutting in motion (Scything) (Fig. 8)
Proceed at a regular pace, with a circular motion
similar to a traditional scythe, without tilting the
cutting line head during the operation.
First try cutting at the right height in a small area, so
as to then achieve a uniform cutting height keeping
the cutting line head at a constant distance from the
ground.
