•
Clean ventilation holes in engine casing regularly.
•
Regularly remove grass residues from the shield and cutting line
spool.
•
Never clean the petrol grass cutter with water, aggressive fluids or
solvents. Clean the petrol grass cutter with brush or delicate cloth.
•
Regularly check technical condition of the ignition plug of the
combustion engine. Replace worn out ignition plug with a new
one recommended by the manufacturer.
•
Use recommended spools with cutting line.
PULLING OUT THE CUTTING LINE
The petrol grass cutter is equipped with cutting line feed system.
The cutting line will be pulled out when the spool is firmly pressed
against the ground. Excessive cutting line will be cut off with blade
located in the shield.
In case the cutting line is torn off or its part is broken inside the
spool cover, the cutting line will not be fed. In such case pull the
cutting line by hand.
PULLING OUT THE CUTTING LINE MANUALLY
Switch off engine of the petrol grass cutter.
•
Use hexagonal key to lock spindle lock hole (
23
) (
fig. E
) and
unscrew cover of spool with cutting line (
15
) (
fig. B
).
•
Hold spool cover firmly.
•
Press in safety catches (
18
) (
fig. C
) at both sides of cover of the
spool with cutting line.
•
Remove lid from the cover of the spool with cutting line.
•
Put in ends of the cutting line and thread them through cutting
line holes (
21
) (
fig. D
).
•
Install lid of the cover of spool with cutting line.
•
Screw cover of spool with cutting line onto spindle.
Be very careful when using petrol grass cutter for vertical
trimming of edges. Stay away from the plane of cutting element
rotation to avoid risk of being hit with an object projected by
the cutting element.
Engine is very hot during operation and just after. Touching it
may cause skin burns.
Exhaust gases contain carbon monoxide, which may cause
poisoning when inhaled. Therefore never start the tool indoors,
in places with poor ventilation or close to flammable materials.
OPERATION AND MAINTENANCE
Ensure the engine is switched off and is cold before cleaning,
checking or repairing the petrol grass cutter. Disconnect
ignition plug wire (35) (fig. K) from the ignition plug to prevent
accidental start up of the engine.
Be careful, the blade for cutting off the cutting line is dangerous.
When the petrol grass cutter is not being used, the blade should
always be secured.
REPLACEMENT OF CUTTING LINE SPOOL
Ensure the engine of petrol grass cutter is switched off.
•
Use hexagonal key to lock spindle lock hole (
23
) (
fig. E
) and
unscrew cover of spool with cutting line (
15
) (
fig. B
).
•
Hold spool cover firmly.
•
Press in safety catches (
18
) at both sides of cover of the spool with
cutting line (
fig. C
).
•
Remove spool with cutting line (
19
) (spring (
20
) should stay in
cover of spool with cutting line) (
fig. D
).
•
Clean inside the cover of spool with cutting line thoroughly,
remove all residues of ground and grass.
•
Unwind both ends of the line from spool by approximately 1
5
cm.
•
Thread ends of cutting line of new spool through cutting line
holes (
21
) in the spool cover (
fig. D
).
•
Firmly push new spool with cutting line into spool cover.
•
Install the spool cover and press in so it snaps (spool cover must be
fully seated and secured with safety catches).
AIR FILTER
Dirty air filter reduces power of combustion engine and causes
increase of fuel consumption. Clean the air filter after each
5
hours
of the grass cutter operation.
•
Remove the air filter shield (
42
) (
fig. O
).
•
Remove the air filter (
41
) (
fig. O
) from the air filter shield.
•
Wash the air filter in warm water with soap.
•
Dry and install the air filter.
Do not wash the air filter in petrol or any other flammable solvent
to avoid fire hazard or appearance of dangerous vapours.
FUEL FILTER (CLEANING / REPLACEMENT)
•
Unscrew the fuel filler plug (
6
).
•
Use wire hook or hexagonal key to remove the fuel filter (
37
) (
fig.
M
) through fuel filler hole.
•
Disassemble the fuel filter and wash it in petrol or replace with
a new one.
•
Install the fuel filter in the fuel tank (
7
) and tighten fuel filler plug.
Be careful during fuel filter installation to prevent contaminations
from getting into the suction line.
IGNITION PLUG
To maintain reliable operation of the device, check condition of the
ignition plug on a regular basis.
•
Wait until the engine cools down.
•
Remove the ignition plug wire (
35
) (
fig. K
) from the ignition plug
(
4
).
•
Use the key for ignition plugs (
34
) (
fig. K
) and unscrew ignition
plug.
•
Clean electrodes of the ignition plug (
36
) (
fig. L
). Adjust distance
between electrodes.
•
Replace ignition plug with a new one when necessary.
STORAGE
Before storage drain the fuel system completely.
•
Drain fuel from the fuel tank, start the engine and allow it to use all
remaining fuel and stop working.
•
Use new fuel each season. Never use any cleaning agents on fuel
tank, it may damage the engine.
•
Pay special attention to keep the ventilation holes of the engine
casing pervious.
•
You can proceed with grass cutter maintenance actions only
described within this instruction manual. Any other action can be
carried out only by authorized service.
•
Do not make any changes in the grass cutter construction.
•
When not in use, the grass cutter should be stored clean, on flat
surface, in dry place and beyond reach of children.
Fuels with alcohol additives (ethanol or methanol) may absorb
moisture, and that during storing causes separation of fuel
blend ingredients and formation of acids. Acidic petrol may
damage the engine.
Be careful, the blade for cutting off the cutting line is dangerous.
When the petrol grass cutter is not being used, the blade should
always be secured.
All faults should be repaired by service workshop authorized by the
manufacturer.
