3.
Remove the air filter (21).
4. Wash the air filter in a luke warm soapy solution.
Do not blow out dirt particles, otherwise there is a risk
of eye injury.
5. Clean the air filter interior using a brush.
6. Allow the air filter to dry well and reinsert it.
7. Re-mount the air filter cover.
Never operate the machine without air filter. Dust and dirt
can enter the engine and cause damages to the machine.
Replace the air filter on a regular basis.
Damaged air filters must be replaced without delay.
Cleaning/replacing the fuel filter
Check the fuel filter (7) if required. A contaminated fuel filter
restricts the fuel supply.
Open the tank cap (8) and pull the fuel filter through the opening
using a wire hook.
⇒ Slight contamination:
Pull the fuel filter from the fuel line and clean it in petroleum
ether.
⇒ Bad contamination:
Replace the fuel filter.
Checking / replacing the spark plug
Do not touch the spark plug (16) or the
spark plug connector (15) when the engine runs.
High voltage!
Risk of burning on the hot engine.
Wear protective gloves.
Check the spark plug and the spark gap on a regular basis.
For this proceed as follows:
1.
Loosen the screws (C) and remove the cover (34).
2.
Pull the spark plug connector from the spark plug.
3.
Remove the spark plug using the supplied spark plug
wrench (25).
The spark gap must be 0.6 to 0.7 mm.
Clean the spark plug when it is contaminated.
Install the spark plug in reverse order.
Do not overtighten the spark plug.
Used spark plug: 1/8 – 1/4 turn
New spark plug: 1/2 turn
A loose spark plug may overheat and damage the
engine.
Tightening the spark plug too firmly may damage the
thread in the cylinder head.
Replace the spark plug:
every 100 hours or each season (whichever case comes
−
first)
−
when the insulating body is damaged,
−
when the electrodes show excessive erosion,
−
when the electrodes show excessive dirt or oil.
24
Use the following spark plug type:
Torch L7T or L8RTF, LD L7T or L8RTF, NGK BPMR7A, Bosch
WSR6F, Champion RCJ7Y
Checking the ignition spark
1.
Remove the spark plug.
2.
Firmly put the spark plug connector (15) on the spark
plug (16) again.
3.
Insert the spark plug socket spanner through the
body opening. The spark plug socket spanner must have
contact to the engine housing (metal).
Do not insert the spark plug socket spanner in the spark
plug hole.
4.
Use an insulated pair of tongs to press the spark plug
against the spark plug socket spanner (25) (away from the
spark plug hole).
5. Slide the ON/OFF switch to the position " I ".
Pull the cranking rope.
If there is no spark visible between the electrodes, the
spark plug may be defective.
Silencer / exhaust outlet
1.
Loosen the screws (D) and remove the cover (23).
2.
Check the tight seat of the screws (E) on the silencer
(6) on a regular basis.
If they are loose, tighten them hand-tight.
Do not retighten the silencer screws when the engine is
hot.
3.
Clean the exhaust outlet (19) on a regular basis.
Care
Clean the hedge trimmer thouroughly after each application so
that the faultless function is kept.
Wear protective gloves when cleaning the cutting
device.
Clean the case with a soft brush or a dry cloth.
Water, solvents and polishing agents shall not be
applied.
Check that the ventilation slots for the motor cooling are free
(risk of overheating).
To minimise the risk of fire make sure that the engine and
silencer are free from dirt, leaves or emerging lubricant.
Clean the cutting device on a regular basis using a brush or
a cloth.
Never clean the knives with water (Risk of corrosion!)
Clean and oil all moving parts regularly.
Never use any grease!
Use for instance environmentally acceptable spray oil.
