Working With Brush Cutter; Working With The Grass Trimmer; Maintenance And Care - ATIKA BF 31-4T Original Instructions Manual

Working with the brush cutter
Kickback backstroke
–
When working with metal blades, a kickback of the whole
machine or a sudden pull forwards may occur if fixed objects
(trees, branches, stones or the like) are hit. Such a kickback
occurs abruptly without advance warning and may result in loss
of control of the machine and hazards to the operator. There is
a particular hazard in badly visible and overgrown areas.
 To keep the control in case of kickback
• Always hold the machine firmly with both hands when
working.
• Make sure that you have a safe stand. Keep your feet
conveniently spread and be always alert to a possible
kickback.
• Do not overestimate your abilities and always keep your
balance when working.
• The cutting blade should have reached its full speed before
cutting.
When brush-cutting, stones and debris may be thrown up
and cause serious injuries. Make sure that the protective hood
is safely mounted.
Failure to install rotating parts (cutting blades) correctly
may result in severe accidents. Check the cutting blade for
secure seating before starting your work.
Mowing
• Incline the machine slightly forward and uniformly move it
from right to left with adequate speed. This way, the cut
material falls on the already mowed area.
• Cut higher grass and denser growth in several passes. For
this, shorten the upper portion of the material to be cut at
first by moving the device to the right. Then, move the
device to the left and cut the lower portion of the material to
be cut.
• When working on slopes mow in stripes. Mow a stripe
parallel to the slope. Move then back on the mowed area
and mow the next stripe.
• Adjust the engine speed and cutting height to the prevailing
conditions. If the engine speed is too low, scrub can
entangle in the cutting tool or the cutting tool may get stuck
in the scrub.
If grass, scrub or other objects entangle in the cutting tool
or if the device vibrates abnormally, immediately stop the
engine and check the machine.
− A blocked angular gear may cause coupling damage.
− Never remove jammed material while the cutting blade is
still rotating. Wait until the cutting blade stands still.
− If the cutting blade is dull, broken or bent, replace it by a
genuine spare part.

Working with the grass trimmer

Trimming
• Incline the machine slightly forward and uniformly move it
from left to right with adequate speed.
• You will get the best trimming results when you cut dry grass.
Do not guide the cutting thread directly at walls and
•
paving stones. Otherwise it will wear off prematurely.
• Cut higher grass and denser growth in several passes to
prevent the spool head from becoming blocked.
A blocked spool head may cause coupling damage.
• Adjust the engine speed and cutting height to the prevailing
conditions. If the engine speed is too low, scrub can entangle
in the cutting tool or the cutting tool may get stuck in the
scrub.
If grass, scrub or other objects entangle in the cutting tool
or if the device vibrates abnormally, immediately stop the
engine and check the machine.
A blocked spool head may cause coupling damage.
−
− The cutting thread is after-running once the lawn trimmer
has been cut off. Shut off the engine and wait till the cutting
blade stops.
− When the thread spool is empty replace it by a genuine
thread spool.
Thread follow-up
During trimming, the cutting thread wears (becomes shorter) or
it may tear off so that it can no longer cut grass.
Such a kickback occurs abruptly without advance

warning and may result in loss of control of the machine and
hazards to the operator. If the cutting thread exceeds the
maximum cutting diameter it will be shortened by the
integrated knife within the protective hood.
Always use the dirt catcher (5a) with integrated
thread knife during trimming.

A damaged dirt catcher must be replaced immediately.

Maintenance and care

Before each maintenance and cleaning work
− Stop the engine.
− Wait until the cutting device does not longer
move.
− Remove the spark plug connector.
− Wear protective gloves in order to avoid
injury to the hands.
Do not carry out maintenance work close to
−
open flames. Risk of fire!
Maintenance and repair work other than those described in this
chapter is only allowed to be carried out by service staff.
Use only original parts. Other parts can result in unexpected
damages and injuries.
For maintaining and cleaning, removed security devices must
unconditionally be mounted properly and proved again.
