Working Instructions; Carefully Advance The Trimming Line To An - Scheppach MPT3400-4PGE Anleitung

Note: If the engine does not start up even after several
attempts, read the section „Engine troubleshooting".
Note: Always pull the starter cord out in a straight line.
If it is pulled out at an angle, then friction will occur
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
seconds 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 running engine.
• The design of the petrol brush cutter allows for
operation 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.
(see Maintenance).
• 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 examine
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.
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 obstacle. When the trimming line comes into
contact with stones, trees, and walls, the line wears
out or breaks off ahead of time.
• Swing the petrol cutting blade like a normal scythe
horizontally from right to left and back again. You
define the cutting height depending on how high
you are holding the tool.
• Never replace the nylon line with a metal wire.

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.
Mowing with brush cutter and hedge trimmer
Use the cutting blade to comb through brushwood,
rank growth, young tree populations (trunk diameter
of maximum 2 cm), and high grass.
• 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.
• 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.
• Cut the hedge in trapezium shape.
• Stretch a guide over the complete length of the hedge
when you want to shorten the upper edge of the
hedge evenly.
• Trim in several passes if you have to cut down a large
portion of the hedge.
• To cut rank growth and brushwood, you "immerse"
the cutting blade from the top.
Best time for hedge trimming:
• Leaved hedge: June and October
• Conifer hedge: April and August
• Quickly growing hedge: from May and then every 6
weeks
Pay attention to breeding birds in the hedge. If so, put
off hedge trimming or leave this area out.
Angle adjustment
By swivelling the cutter head, the hedge trimmer can
be adjusted to the working conditions from +90° to
-75°. Fig. 42.
• Warning! Adjust the angle only when the motor has
been turned off.
• Push both levers down and put the cutter head in
the required position. Fig. 41
• Release both levers until they click into place in the
notch.
• Before use, check that the adjustment levers have
clicked into place properly. Fig. 42
Oil the blades and the angle adjustment each time
before starting work, with environmentally friendly
lubricant.
Regularly oil the blades during working hours as well.
Warning! Oil the tool only when the motor has been
turned off.
