Cutting tools
When installing the cutting tool, check the condition of the blade. If it is damaged (cracked, bent, broken off,
etc.), replace it.
After installing the blade, check again that the hole in the blade is level with the arm of the blade tang.
Spin the blade, check again that the blade has no tendency to rotate irregularly.
Check that the blade is installed with the sharp edge moving in the direction of rotation. Never install it the
other way around.
Check that the cutting tool is properly assembled by turning it without load (1 minute is enough).

Mixing the fuel mixture
6. MIXING THE FUEL MIX
WARNING!
Never pour fuel into the fuel tank in a closed and unventilated location.
Do not pour fuel in the vicinity of an open flame or a source of sparks.
Do not overfill the petrol tank. Before starting the engine, make sure that all spilt fuel is wiped away.
If the engine is hot, DO NOT POUR IN FUEL.
For this type of two-stroke engine a mixture of lead-free petrol and two-stroke engine oil is used at a ratio
of 40 : 1.
ATTENTION! A fuel mix that is mixed at a ratio other than 40:1 may damage the engine. Make sure that this
fuel mix is mixed correctly.
When mixing petrol with two-stroke engine oil, use only petrol containing NO ETHANOL or METHANOL (types
of alcohols).
Use quality petrol with an octane number of 95 or higher. This will help prevent possible damage to the fuel
system and other parts of the engine.
We recommend the use of the calibrated container supplied with the brush cutter for mixing the fuel mix.
DO NOT MIX THE PETROL AND OIL DIRECTLY IN THE FUEL TANK.
Storing fuel
Only store fuel in a clear, safe and approved canister. Inform yourself about and adhere to local directives related
to the type and storage of canisters filled with fuel.
IMPORTANT
Fuel for two-stroke engines may separate. Prior to every use, thoroughly shake the canister with fuel.
Stored fuel ages. Do not mix more fuel than you expect to consume within one month.
7. OPERATION
ENGINE STARTING AND STOPPING PROCEDURES STARTING COLD ENGINE

8. PREPARING FOR OPERATION
IMPORTANT:
Follow instructions for preparing the fuel mix! Not following these instruction may damage the engine! Do not
use fuel that has been stored for longer than two months. A fuel mix stored for longer than two months will cause
problems at start up and lower engine performance. If the fuel mix is stored for longer than two months, it should
be removed and new fuel must be used.
Points to check before starting work
1. Check whether any screws, nuts and installation elements are loose. Tighten any loose screws.
2. Check whether the air filter is dirty. Prior to starting work, remove all dirt from the air filter.
3. Make sure that the plastic head guard and the blade is securely fastened in place.
4. Check the fuel tank for leaks.
5. Check the blade or the string trimmer head for damage.
9. SAFETY WORKING WITH BRUSH CUTTER
USING THE SHOULDER HARNESS

2. Adjust the shoulder-harness button, and move the hook to your waist, then adjust the belt (If there is a belt).
3. Hang the latch tab on the harness hook.
4. If the brush cutter does’t balance, then adjust the harness hanger, and the handlebar, until it balances.
WARNING CAUTION

CUTTING WITH A NYLON HEAD
Line head rotates in a counter CLOCKWISE direction.
The CUT-OFF KNIFE will be on the right side of the
debris shield.
WARNING DANGER
The proper debris shield must be in place on the unit
when nylon cutting line is used. The cutting line can
flap around if too much line is exposed. Always use
the plastic debris shield with cut-off knife when using
nylon cutting heads.
For nearly all cutting, it is good to tilt the line head
so that contact is made on the part of the line circle
where the line is moving away from you and the debris
shield. (See appropraite picture) Thisresults in the
debris being thrown away from you.
WARNING DANGER
Tilting the head to the wrong side will shoot the debris
TOWARDS you.If the line head is held flat to the ground
so that cutting occurs on the whole line circle, debris
will be THROWN at you, drag will slow the engine
down, and you will use up a lot of lines.
WARNING DANGER
Use only quality nylon monofilament line of the
diameter 2.5mm. Never use wire or wire-reinforced
line in place of nylon trimer line. Load your nylon line
cutting head only with nylon trimmer line of the proper
diameter.
WARNING DANGER
Use extreme caution when operating over bare spots
and gravel, because the line can throw small rock
particles at high speeds. Debris shields on the unit
cannot stop objects which bounce or ricochet off hard
surfaces.

TRIMMING:
This is feeding the trimmer carefully into the material
you wish to cut. Tilt the head slowly to direct debris
away from you. It’ cutting up to a barrier such as
fence, wall or tree .approach from an angle where
anydebris ricocheting off the barrier will fly away from
you. Move the line head slowly until the grass is cut
right up the barrier, but do not jam(overfeed )the line
into the barrier. If trimming up to a wire mesh or chain
linked fence be careful to feed only up to wire. If you go
to far the line will snap off around the wire. Trimming
can be done to cut through weed stems one at a time.
Place the trimmer line head near the bottom of the
weed-never high up which could cause the weed to
chatter and catch the line. Rather than cut the weed
right through, just use the very end of the line to wear
through the stem slowly.
WARNING DANGER
Do not use a steel blade for edging or scalping
SCALPING AND EDGING:
Both of these are done with the line head tilted at
a steep angle scalping is removing top growth leaving
the earth bear. Edging is trimming the grass back
where it has spread over a sidewalk or drive way.
During both edgingand scalping, hold the unit a steep
angle and in a position where the debris, and any
dislodging dirt and stones, will not come back towards
you even if it ricochets off the hard surface. Although
the picture shows how to edge and scalp every
oprator must find for himself the angles which suits his
body size and cutting situation.
WARNING DANGER
Do not trim in any area where there are strands of
fencing wire, Wear protective safty protecting, Do not
cut where you cannot see what the cutting device is
cutting.
CUTTING WITH A BLADE
There are many different types of blades, however the
two most commonly used are the following.

Safety working with brush cutter
BRUSH BLADE is used for cutting brush and weeds up
to 3/4” in diameter. Only 255mm 3-blade can be used
in this type of brush cutter.
WARNING DANGER
DO NOT USE A BRUSH CUTTER FOR CUTTING TREES.
WARNING DANGER
Do not cut with dull, cracked or damaged metal blade.
Before cutting growth, inspect for obstructions such as
boulders, metal stakes or strands of wire from broken
fences. If an obstruction cannot be removed, mark its
location so that you can avoid it with the blade. Rocks
and metal will dull or damage a blade. Wires can
catch on the blade head and flap around or be thrown
into the air.
Blade thrust is the reaction which may occur when
the spinning blade contacts anything it cannot cut.
This contact may cause the blade to stop for an instant
,and suddenly ‘thrust” the unit away from the object
that was hit.This reaction can be violent enough to
cause the operator to lose control of the unit. Blade
thrust may occur without warning if the blade snags
, stalls or binds.This is more likely to occur in areas
where it is difficult to see the material being cut.For
cutting ease and safely, approach the weeds being cut
from the right to the left,in the event that an unexpected
object or woody stock is encountered,this could
minimise the blade thrust reaction.
SCYTHING WEEDS. This is cutting by swinging the
blade in a level arc. It can quickly clear areas of field
grass and weeds. Scything should not be used to cut
large, tough weeds or woody growths.
NOTE
Do not use a brush blade to cut trees which exceed
a diameter of 1/2 to 3/4 inches.

FZS 5025-B
Safety working with brush cutter
Scything can be done in both directions, or just in one
way which results in the debris being thrown away
from you.
Use the side of the blade that it is rotating away from
you. Tilt down the blade slightly on this same side
You will be hit by some debris if you scythe in both
directions.
Do not force the blade to cut. Do not change the angle
of cut after into the wood. Avoid using any pressure or
leverage which could cause the blade to bind or crack.
