• Stretch a guide over the complete length of the
hedge when you want to shorten the upper edge of
the hedge evenly.
• Trim in several passes if you have to cut down a
large portion of the hedge.
Best time for hedge trimming:
• Leaved hedge: June and October
• Conifer hedge: April and August
• Quickly growing hedge: from May and then every
6 weeks
Pay attention to breeding birds in the hedge. If so,
put off hedge trimming or leave this area out.
At any case pay attention to all safety instructions.
10. Maintenance
Before each maintenance and cleaning work
- Stop the engine.
- Wait until the cutting device does not longer move.
- Stop the engine and pull off the spark plug connec-
tor (with the exception of idle speed adjustment).
Do not carry out maintenance work close to open
flames. Risk of fire.
Maintenance and repair work other than those de-
scribed in this chapter is only allowed to be carried
out by service staff.
For maintaining and cleaning, removed security
devices must unconditionally be mounted prop-
erly and proved again.
Use only original parts. Other parts can result in un-
expected damages and injuries.
In order to avoid possible injuries wear gloves.
To guarantee a long and reliable usage of the hedge
trimmer carry out the following maintenance works
regularly.
Check the hedge trimmer for obvious defects
such as
- loose fastening elements
- worn or damaged components
- deformed, broken or damaged cutting device
- leaks from the fuel tank cap or fuel lines
Check the hedge trimmer after each application
for
- wear and tear, in particular sliding play of the cut-
ting device
- correct assembly and faultless covers and protec-
tive devices.
Necessary repair or maintenance operations have to
be carried out before the usage of the hedge trim-
mer.
Adjusting the cutting device
Readjust the sliding play if cut material is clamped
between the blades or the play has increased due to
normal wearing of the cutting device after a longer
period of use.
To obtain good cutting results the free motion be-
tween the blades and the sword must be correctly
adjusted.
For this proceed as follows:
1. Loosen the nuts (A) on the top surface of the cut-
ting device.
2. Slightly tighten the screws (B) on the underside (if
required loosen them previously).
3. Turn the screw back anticlockwisely by a quarter
up to a half turn.
4. Use a screwdriver to hold the screw and firmly
tighten the nuts.
The sliding play is correctly adjusted if the washer
under the screw head can just be freely moved
back and forth by hand.
5. Lubricate the cutting device using environmental-
compatible lubricating oil.
If the play is too small, this may cause a great ex-
tent 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 fitting (10).
2. Force some grease into the zerk fitting.
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
continues to run in idle mode.
Do not continue working with the hedge trimmer in
such a condition.
Cleaning / replacing the air filter
Clean the air filter from dust and dirt on a regular ba-
sis to prevent
- starting problems,
- loss of output,
- too high fuel consumption.
Clean the air filter every 8 operating hours, or more
frequently in dusty environments.
1. Put the choke (4) to „cold start" to prevent dirt
particles from coming into the carburettor.
2. Remove the air filter cover (8).
3. Remove the air filter (D).
