Check the spark plug and the spark gap on a regular
basis.
For this proceed as follows:
1. Pull the spark plug connector from the spark plug.
2. Remove the spark plug using the supplied spark
plug wrench.
The spark gap must be 0.6 to 0.7 mm.
Clean the spark plug when it is contaminated.
Replace the spark plug:
- once in a month if the device is often used
- when the insulating body is damaged,
- when the electrodes show excessive erosion,
- when the electrodes show excessive dirt or oil.
Checking the ignition spark
1. Pull the spark plug connector from the spark plug.
2. Remove the spark plug using the supplied spark
plug socket spanner.
3. Remove the spark plug.
4. Firmly connect the spark plug connector.
5. Use an insulated pair of tongs to press the spark
plug against the engine body (away from the spark
plug hole).
6. Slide the ON/OFF switch to the position „I„.
7. Firmly pull the cranking rope on the cranking han-
dle.
A spark between the electrodes is a sign of proper
functioning.
Silencer / exhaust outlet
Do not retighten the silencer screws when the engine
is hot.
1. Check the tight seat of the screws (G) on the si-
lencer (H) on a regular basis.
- If they are loose, tighten them hand-tight.
2. Clean the exhaust outlet (K) on a regular basis.
Care
Clean the hedge trimmer thouroughly after each appli-
cation so that the faultless function is kept.
Wear protective gloves when cleaning the cutting de-
vice.
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).
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.
Maintenance schedule
Operation - Maintenance interval
Adjust the cutting device If required Adjust the idle
speed If required Tighten the silencer screws If required
Clean/replace the fuel lter. If required Clean/replace
the air lter Every 8 hours of operation (more frequent
in case of dusty environments) Lubricate the gearbox
Every 20 hours of operation, at least once in a year
5. Lubricate the cutting device using environmental-
compatible lubricating oil.
If the play is too small, this may cause a great extent of
heating and thus damage to the device.
Lubricating the gearbox
Lubricate the gearbox every 10 to 20 operating hours.
1. Put the grease gun onto the zerk tting (10).
2. Force some grease into the zerk tting.
Adjusting the idle speed
If the cutting device continues to run while the engine
idles, you have to correct the idle speed.
1. Allow the engine to run warm for 3-5 minutes (no
high speed).
2. Turn the adjusting screw (C):
clockwisely
- idle speed increases (+)
counterclockwisely
- idle speed decreases ()
Contact the manufacturer if the cutting device still con-
tinues to run in idle mode.
Do not continue working with the hedge trimmer in such
a condition.
Cleaning / replacing the air lter
Clean the air lter from dust and dirt on a regular basis
to prevent
- starting problems,
- loss of output,
- too high fuel consumption.
Clean the air lter every 8 operating hours, or more fre-
quently in dusty environments.
1. Put the choke (4) to „cold start“ to prevent dirt par-
ticles from coming into the carburettor.
2. Remove the air lter cover (8).
3. Remove the air lter (D).
4. Wash the air lter in a luke warm soapy solution.
Do not blow out dirt particles, otherwise there is a
risk of eye injury.
5. Clean the air lter interior using a brush.
6. Allow the air lter to dry well and reinsert it.
7. Re-mount the air lter cover.
Replace the air lter on a regular basis.
Damaged air lters must be replaced without delay.
Cleaning/replacing the fuel lter
Check the fuel lter (E) if required. A contaminated fuel
lter restricts the fuel supply.
Open the tank cap (12) and pull the fuel lter through the
opening using a wire hook.
Slight contamination:
- Pull the fuel lter from the fuel line and clean it in pe-
troleum ether.
Bad contamination:
- Replace the fuel lter.
Checking / replacing the spark plug
Do not touch the spark plug (F) or the spark plug con-
nector (16) when the engine runs. High voltage!
Risk of burning on the hot engine. Wear protective
gloves.
