Working Instructions - Scheppach MFH5200-4P Bedienungs- Und Wartungsanleitung

When releasing the throttle lever, the motor be-
comes idle and the cutting tools stop. Fig. 23.
The cutting tools should not continue turning and
should not move when the motor is idle.
7. If there are problems, immediately turn the mo-
tor switch (7) to "0" so the motor stops. Caution:
The cutting tools may continue turning for a few
seconds. Fig. 23
8. If any problem occurs, pull the pin of safety belt,
then release the brush cutter immediately. Fig. 17
9. If the motor is warm, you can leave the choke le-
ver in the "warm start and work" position.
Note: If the engine does not start up even after sev-
eral attempts, read the section „Engine troubleshoot-
ing".
Note: Always pull the starter cord out in a straight
line. If it is pulled out at an angle, then friction will oc-
cur on the eyelet. As a result of this friction, the cable
will become frayed and will wear away faster. Always
hold the starter handle when the cable retracts.
Never allow the cable to snap back when it has been
pulled out.
Note: Do not start the motor in tall grass.
m Attention: When the engine has been switched
off, the cutting unit continues running for several sec-
onds therefore do not touch the cutting unit until it
has come to a standstill!

9. Working instructions

Working with brush cutter / grass trimmer
• When you work with the petrol brush cutter for the
first time, familiarize yourself with the operation
and control of the petrol cutting blade without run-
ning engine.
• The design of the petrol brush cutter allows for op-
eration only at the right side of the user's body.
• Keep the petrol brush cutter firmly with both hands
on the handles.
• Always make sure that the cutting tool continues to
rotate briefly after the throttle has been released.
• Always so that the cutting tool no longer turns in a
proper engine idle not press down the throttle.
• Always work with high speed so you have the best
cutting results.
• Poke when working on a stone or a tree, turn off
the engine and remove the spark plug then exam-
ine the petrol brush cutter for damage.
• Caution: Always be extra careful when working in
difficult terrain and slopes. Cut tall grass gradually
so as not to overload the unit.
• Always wear safety glasses and hearing protection
and a safety helmet.

• Use the cutting blade to comb through brushwood,
rank growth, young tree populations (trunk diam-
eter of maximum 2 cm), and high grass.
• While using metal cutting tools, there is generally
a risk of recoil, when the tool hits a solid obstacle
(stones, trees, branches, etc.). Thereby, the tool is
hurled backwards against the rotating direction.
• To cut rank growth and brushwood, you "immerse"
the cutting blade from the top.
CAUTION: Be especially careful, when using this
working technique, because the further away the cut-
ting tool is from the ground, the higher is the risk that
objects to be cut and particles will be hurled side-
ways.
Mowing with grass trimmer
• Use the plastic line cassette for a clean cut also at
uneven edges, fencing posts, and trees.
• Carefully advance the trimming line to an obstacle,
and use the tip of the line to cut around the ob-
stacle. When the trimming line comes into contact
with stones, trees, and walls, the line wears out or
breaks off ahead of time.
• Never replace the nylon line with a metal wire.
RISK OF INJURIES
Automatic thread trimming (Fig. 36)
The petrol cutting blade is delivered with a filled line
cassette.
This line will wear out during work. To feed new line,
forcefully press the head of the line cassette onto the
ground while the engine is running at working speed.
The line is automatically fed due to centrifugal force.
The knife at the line guard will shorten the trimming
line to the correct length.
Run the trim line approach cautiously to an obstacle
and cut with the tip of the line around the obstacle.
Working with hedge trimmer
• The hedge trimmer may be used only for cutting
hedges, bushes and shrubs
• Hold the hedge trimmer with both hands on a safe
distance from the body.
• The maximal diameter to cut depends on the
wood's type, age, moisture and hardness.
• Therefore cut very thick branches using branch
shears to your desired length before trimming the
hedge.
• Due to its double sided knives the hedge trimmer
can be guided forward and backward or by oscillat-
ing movements from one to another side.
• At first cut the sides of the hedge and then the up-
per edge.
• Cut the hedge from the bottom up.
• Cut the hedge in trapezium shape.
