Operating and maintenance instructions
ENGLISH 12
8. 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.
8.1 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).
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 cuttings,
undergrowth etc. from the blade. Immediately
replace blunt or damaged tools, even if only slightly
damaged.
Sharpening the cutting blade
Sharpening of the cutting blade must only be
carried out by an authorised agent.
•
Sharpening angle: 45°
• Always sharpen towards the cutting edge
• Only work with a forward stroke
• Following sharpening, remove the burr with a
whetstone and spray the blade with a
maintenance and treatment oil.
8.2 Gear lubrication
Re-lubricate the blade gearbox (8), angular gear (5)
and clutch mid-section (12) with SOLO "Special
gearbox flow grease" (part no.
00 83 180) approx. Every 20 operating hours.
Cutter gearbox:
With a grease gun, press about 20g gearbox flow
grease into the blade gearbox grease nipple (8) (3-5
shots).
Angular gear:
With a grease gun, press about 10 g gearbox flow
grease into the angular gear grease nipple (5) (2-3
shots).
Clutch mid-section:
With a grease gun, press about 20g gearbox flow
grease into the clutch mid -section grease nipple
(12) (3-5 shots).
8.3 Air Filter Maintenance
Contaminated air filters cause a reduction in engine
performance and increase fuel consumption with
more pollutants in the exhaust gas. Engines are less
likely to start readily with a contaminated air filter.
Carry out the following maintenance jobs regularly.
