Safety provisions
ENGLISH 10
In addition to the safety provisions already listed, the following safety provisions also apply when working
with the motor device:
•Danger of poisoning! Once the engine is running, the power tool produces toxic exhaust that may be
invisible and odourless. Never start the power tool in closed rooms. Special danger also applies in
narrow situations, troughs or ditches. Only work here when it is absolutely certain that there is sufficient
air exchange and that no toxic gases may accumulate.
•Increased danger of fire! Do not smoke at the workplace – not even in the proximity of the power tool.
•Secure the workplace against accidental access by third parties, e.g. with warning signs. Only persons
involved and wearing protective clothes must be present within 30 metres [approx. 30 yards] around the
working area.
•Check the site of deployment for possible dangers.
– Spark formation during cutting means that work must never be performed close to potentially
explosive gases of liquids, or easily flammable objects.
– No electrical lines must be placed in the area to be cut.
– Objects that may fall off or topple over during work must be secured or removed from the working
environment first.
– Prepare the workplace so that secure backing away is possible.
•The work piece to be cut must be free of foreign bodies such as screws, nails or stones.
•When working in residential areas, observe the noise protection provisions.
•Work carefully, considerately and calmly and do not endanger any other persons.
– Ensure good sight and light conditions.
– Always remain within calling distance of other persons who may administer first aid in emergencies.
– Put in working breaks in time.
– Be attentive towards possible danger sources and take the corresponding preventive measures.
Consider that use of hearing protection limits perception of sounds. Signal sounds, calls, etc. that
announce danger may also be missed.
– Observe tripping dangers and obstacles. Never work on unstable undergrounds.
– Always hold on to the power tool with both hands and always ensure a safe and firm stance.
– Never cut standing on a ladder.
– Guide the power tool so that no body part is located in the extended swivel range of the cutting disc.

Power tool description
ENGLISH 14
Release of the throttle control (10)
•
Grasp rear handle (6) with the right hand. The
throttle control lock (9) is operated with the palm.
èThe throttle control (10) is released.
Starter handle (16) and starter rope; èChap. 6.3, page 25
Primer (20)
In the delivery condition, after extended resting
tim
e and with the tank completely empty, there is
no fuel yet in the carburettor after fuelling up.
Starting process:
èChap. 6.1, page 24
To facilitate the starting process, fuel can be
pumped in
to the carburettor. Push the primer (20)
repeatedly until fuel appears in the primer.
Excess fuel is automatically flushed back into the
tank from the primer.
Decompression valve (21)
When the decompression valve (21) is depressed,
the compression pressure in the combustion
chamber is reduced. This means that the engine
offers less resistance during start
-up, which makes
it noticeably easier to start t
he engine.
Starting process:
èChap. 6.1, page 24
The decompression val
ve is closed automatically
when the motor is running.
If you need to pull the starter handle
(16
) more than
once to start the engine (e.g. during a cold start),
you do not need to depress the decompression
valve again.

The cutting discs used must correspond to the specifications from chap. 7.1 on page 26!
The power tool spindle is designed for cutting discs with an inner bore of 20 mm.
Cutting discs with 1" inner bores must only be installed together with the spindle adapter disc.
Installation of cutting discs with 1" inner bore: èChap. 5.2, page 17!
When using cutting discs with an inner bore of 20 mm, no additional spindle adapter disc is
required.
•For cutting disc installation, the power tool must be put securely on the ground. Securely hold the power
tool at the top handle with the left hand and push it firmly onto the ground. èChap. 5.4, page 18
•Insert blocking pin (a) entirely into the cutting disc blocking opening (12) to block the spindle. Screw out
cutting disc attachment screw (11). Remove disc (b) and pressure disc (c).
The rotating direction of the cutting disc is always
as indicated by the arrow above – independently of
whether the cutting device is installed in the centre
or outer position.
•Put cutting disc (1) on spindle.
For cutting discs with specified rotating direction (arrow on the cutting disc), observe correct alignment
of the cutting disc during assembly (for rotation direction of the cutting disc, see above).
•Push on pressure disc (c) so that the curved side points southwards, i.e. away from the cutting disc.

•Push on disc (b) and turn in cutting disc attachment screw (11).
•Insert blocking pin (a) entirely into the blocking opening (12) and firmly tighten (30 Nm [22.1 ft·lbf]) the
cutting disc attachment screw (11).
Securely hold the power tool at the top handle with one hand and push it firmly onto the ground.
•Remove the blocking pin (a).
The power tool's spindle is designed for cutting discs with an inner bore of 20 mm.
For proper installation of cutting discs with a 1" inner bore, the spindle adapter disc is required that
is included with the delivery of the power tool.
The spindle adapter disc ensures correct fit of the 1" cutting disc on the spindle.
•Installation of cutting discs with 1" inner bore
takes place according to chap. 5.1 as of page 16.
•
After applying the cutting disc on the spindle,
however, the spindle adapter disc (e) must be
put on the spindle (f) additionally.
•
Put the spindle adapter disc (e) onto the spindle
so that it inserts between spindle and inner bore
of the cutting disc.
The support area of the spindle adapter disc
must point outwards in the installed condition, i.e.
away from the spindle.
The correct orientation of the spindle adapter
disc is mandatory to directly connect the plane
inner area to of the pressure disc to the cutting
disc. Only this warrants secure attachment of the
cutting disc.
•
Application of the pressure disc and all following
steps must be performed again according to
chap. 5.1.
•For cutting disc uninstallation, the power tool must be put securely on the ground. Securely hold the
power tool at the top handle with the left hand and push it firmly onto the ground. èChap. 5.4, page 18
•Insert blocking pin (a) entirely into the cutting disc blocking opening (12) to block the spindle. Screw out
cutting disc attachment screw (11). Remove disc (b) and pressure disc (c) (also see chap. 5.1).
•Remove cutting disc from the spindle. For cutting discs with a 1" inner bore, the spindle adapter disc
also must be removed from the spindle.
•Put the pressure disc back onto the spindle so that the curved side points outward.
•Put on disc (b) and turn in the cutting disc attachment screw (11) again. èChap. 5.1.
•Insert blocking pin (a) entirely into the blocking opening (12) and firmly tighten (30 Nm [22.1 ft·lbf]) the
cutting disc attachment screw (11) again.
Securely hold the power tool at the top handle with one hand and push it firmly onto the ground.
•Remove the blocking pin (a).

The protective cowl (2) can be swivelled forward
and backward in a limited area.
For adjustment of the protective cowl, the power
tool must be put securely on the g
round. Securely
hold the power tool at the
top handle (4) with the
left hand and push it firmly onto the ground. With
the right hand at the
handle for protective cowl
adjustment
(3), swivel the protective cowl
accordingly.
To keep sparks
and particles torn out in cutting
away from the user, the protective cowl always
must be swivelled forward as far as the working
situation permits.
If the separating device has been installed in the outer position, ensure when adjusting the
protective cowl that the water supply line is not clamped and that contact between the cutting disc
and water supply line in operation is excluded.
Danger to health!
Direct skin contact with petrol and breathing in of petrol fumes must be excluded.
The high-performance two-stroke engine of this power tool requires an oil-petrol mix in the combustion
chamber (oil and petrol = fuel mix).
Models 880-12 and 880-14
Models 880-12 and 880-14 are equipped with a fuel
tank
(18).
Fuel tank for fuel mix according to the mix
table below.
Unsuitable fuels or deviations of the mix ratio
may cause engine damage!
The fuel mix must be formed from
the following
components:
•
Lead-free regular petrol or lead-free super petrol
(octane number ≥92 RON)
•
Branded 2-stroke engine oil co
rresponding to the
standard ISO-L-EGD or JASO FD
We recommend the "SOLO Profi 2-stroke engine oil" offered by us at a mixing ratio of oil:petrol of
