- Choke: Set the choke knob in the open
- Repeat pulling the cord until engine start. When the
engine starts, allow the engine to warm up with the
throttle lock engaged. Then, pressing throttle trigger to
release the throttle lock. (Fig. 27)).
Do not pull the starter cord all the way out and do not let
go of the starter handle when the cord is fully extended.
This can damage the machine.
Do not put any part of your body in marked area. Contact
can result in burns to the skin, or electrical shock if the
spark plug cap has been damaged. Always use gloves.
Do not use a machine with damaged spark plug cap.
IMPORTANT If the starter rope is pulled
repeatedly with the choke on, it may flood the
engine and make starting difficult.
If you happen to food the engine, repeat the hot start
procedure a few times to eliminate any excess fuel.
11.3.2.2 Hot starting
To hot start the engine immediately after it has stopped,
follow steps a – b – d – g of the above procedure, making
sure the primer bulb is activated 2-3 times only.
11.3.2.3 Stopping: (Fig. 28)
Stop the engine by switching off the ignition.

11.4 General working instructions

IMPORTANT! This section describes the basic
safety precautions for working with brush
cutters and trimmers.
If you encounter a situation where you are uncertain how
to proceed you should ask an expert. Contact your dealer
or your service workshop.
Avoid all usage which you consider to be beyond your
capability.
You must understand the difference between forestry
clearing, grass clearing and grass trimming before use.

11.4.1 Basic working techniques

Always slow the engine to idle speed after each working
operation. Long periods at full throttle without any load on
the engine can lead to serious engine damage.
Sometimes branches or grass get caught
between the guard and cutting attachment.
Always stop the engine before cleaning.
Machines fitted with grass blades can be
thrown violently to the side when the blade
comes into contact with a fixed object. This is
called blade thrust. A blade thrust can be
violent enough to cause the machine and/or
operator to be propelled in any direction, and
possibly lose control of the machine. Blade
thrust can occur without warning if the machine
snags, stalls or binds. Blade thrust is more
likely to occur in areas where it is difficult to
see the material being cut.

Avoid cutting with the area of the blade between
. (Fig. 26).
the 12 o'clock and 3 o'clock positions. Because
of the speed of rotation of the blade, blade
thrust can occur if you attempt to cut thick stems with
this area of the blade.
11.4.2 Grass clearing using a grass blade
Grass blades and grass cutters must not be used on
woody stems.
A grass blade is used for all types of tall or coarse grass.
The grass is cut down with a sideways, swinging
movement, where the movement from right-to-left is the
clearing stroke and the movement from left-to- right is the
return stroke. Let the left-hand side of the blade (between
8 and 12 o'clock) do the cutting.
If the blade is angled to the left when clearing grass, the
grass will collect in a line, which makes it easier to collect,
e.g. by raking.
Try to work rhythmically. Stand firmly with your feet apart.
Move forward after the return stroke and stand firmly
again.
Let the support cup rest lightly against the ground. It is
used to protect the blade from hitting the ground.
Reduce the risk of material wrapping around the blade by
following these instructions:
- Always work at full throttle.
- Avoid the previously cut material during the return
stroke.
Stop the engine, unclip the harness and place the machine
on the ground before you start to collect the cut material.
11.4.3 Grass trimming with a trimmer head
11.4.3.1 Trimming (Fig. 29)
Hold the trimmer head just above the ground at an angle.
It is the end of the cord that does the work. Let the cord
work at its own pace. Never press the cord into the area
to be cut.
The cord can easily remove grass and weeds up against
walls, fences, trees and borders, however it can also
damage sensitive bark on trees and bushes, and damage
fence posts.
Reduce the risk of damaging plants by shortening the cord
to 10-12 cm and reducing the engine speed.
11.4.3.2 Clearing (Fig. 30)
The clearing technique removes all unwanted vegetation.
Keep the trimmer head just above the ground and tilt it.
Let the end of the cord strike the ground around trees,
posts, statues and the like.
CAUTION! This technique increases the wear
on the cord.
The cord wears quicker and must be fed forward more
often when working against stones, brick, concrete, metal
fences, etc., than when coming into contact with trees and
wooden fences.
When trimming and clearing you should use less than
full throttle so that the cord lasts longer and to reduce the
wear on the trimmer head.
