7. Operating and maintenance instructions
The maintenance and the repair of modern
machines as well as their safety-relevant
assemblies require qualified specialised training
and a workshop equipped with special tools and
test equipment. Consequently the manufacturer
recommends that all tasks not described in these
operating instructions be carried out by a
specialised workshop. That specialist has the
required training, experience, and equipment at his
disposal, to provide you with the most cost-
effective solution for such work. He will provide
additional help in word and deed.
After a running-in time of app. 5 hours, all
accessible screws and nuts (except the carburettor
adjusting screws) must be checked for tightness
and they must be retightened, if required.
7.1 Blade
Before hedge trimming and after cleaning, treat
the clean blade with maintenance and treatment
oil. We recommend the "Solo maintenance and
treatment oil" (Part no: 00 83 163).
Please note: Never use grease.
To clean the blade after hedge trimming, we
recommend the use of "SOLO Universal-Reiniger
(Cleaner)" (Part no: 00 83 116). After a short
period of soaking in, the ingrained remains of
cuttings on the blade are soft and solvent. They
can then be removed easily with a cloth.
Check the blade at regular intervals and when
cutters operate unusually or if the blades are
jammed. For this, the engine must be switched off
and the blade must be stopped. Clean all
clippings, brush, etc. from the cutter. Ask your
local service shop immediately to sharpen or
replace the blade if it is blunt or damaged, even if
it shows only slight cracks.
Let your service shop sharpen the blade regularly.
During this service, always clean the guide nuts
after removing the blade.
7.2 Checking the function of the cutter brake
Pressing the throttle safety catch releases the
throttle and the blade brake. Releasing the throttle
safety catch applies the blade brake again.
Check the function of the blade brake before
commencing work.
To do this, start up the power tool in the normal
way under part throttle. When the throttle control
lock is not pressed, the cutting blades are blocked
even under part throttle (cutting blade brake).
You should also check that the cutting blade brake
engages properly when the cutting blades are
being driven. To do this, briefly apply the throttle
while the tool is running, then open your right hand
to release the throttle control lock. Make sure that
you keep a firm grip on the power tool while doing
this. The cutting blades must come to a standstill.
The power tool must not be used if the cutting
blade brake (via the throttle control lock) does not
operate properly. In this case you should
immediately have the unit checked by a specialist
workshop.
7.3 Gearbox maintenance
We recommend the use of the SOLO gear grease
for hedge trimmer (part no. 00 83 190). Top up with
grease every 10 - 20 hours (filler screw 18a or
grease nipple 18b by using a grease gun -part no.
00 80 432).
