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 adequate protective equipment and 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, water or gas pipes or flammable substances 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 operator mobility is possible.

3.9 During work

Power tool description
ENGLISH 11
If metals or mineral materials, such as stone, masonry, concrete or ceramics are processed with the power
tool, fine dust, dust, steam and smoke that contains substances hazardous to health may arise. These
substances may cause severe or fatal diseases, such as respiratory diseases, cancer, damage to the
reproductive system and genetic code (malformation of progeny).
For example, crystalline silicone dioxide can be released when processing quartz-containing materials
such as stone, masonry, granite or concrete. Respirable crystalline silicone dioxide may trigger severe or
fatal respiratory diseases, such as silicose, and is suspected of being carcinogenic.
A list of substances hazardous to health might possibly be available from the country-specific authorities,
institutes or professional associations.
If you cannot assess the risk connected with use and setup of the power tool and the material
processed, read up the following documents on the health and safety risks:
– Material-specific safety data-sheets
– Operating instructions of the power tool
– Work instructions and safety provisions of your employer
– Information and recommendations of your dealer, specialist dealer or specialist workshop
– Information of the country-specific authorities, institutes and professional associations
Always observe all the work instructions, safety notes and safety provisions for the secure and effective
handling of the cutting materials and the power tool that have been published by your employer,
country-specific authorities, institutes and professional associations.
If possible avoid the generation of fine dust, dust, steam and smoke by the corresponding work conduct
and work techniques.
If possible, use cut-off wheels suitable for wet cutting and the water connection of the power tool.
When cutting with water supply, the dust is reduced, visibility is improved and the cut-off wheel service
life is increased by the cooling effect of the water.
If danger from inhalation of fine dust, dust, steam and smoke cannot be excluded by technical
measures, such as use of the power tool's water connection or a suitable extraction device, all persons
in the proximity and users of the power tool must wear suitable breathing protection equipment to
protect them from dust.

Release of the throttle control (10)
Grasp rear handle (6) with the right hand. The
throttle control lock (9) is operated with the palm.
The throttle control (10) is released.
Starter handle (16) and starter rope; Chap. 6.3, page 25
Primer (20)
In the delivery condition, after extended resting
time and with the tank completely empty, there is
no fuel yet in the carburettor after fuelling up.
Starting process: Chap. 6.1, page 24
To facilitate the starting process, fuel can be
pumped into 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 the engine.
Starting process: Chap. 6.1, page 24
The decompression valve is closed automatically

The cut-off wheels used must correspond to the specifications from chap. 7.1 on page 26!
The power tool spindle is designed for cut-off wheels with an inner bore of 20 mm.
Cut-off wheels with 1" inner bores must only be installed together with the spindle adapter disk.
Installation of cut-off wheels with 1" inner bore: Chap. 5.2, page 17!
When using cut-off wheels with an inner bore of 20 mm, no additional spindle adapter disk is
required.
For cut-off wheel 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. Chap. 5.4, page 18
Insert blocking pin (a) entirely into the cut-off wheel blocking opening (12) to block the spindle.
Unscrew cut-off wheel attachment screw (11). Remove wheel (b) and outer mounting flange (c).
The rotating direction of the cut-off wheel is always
as indicated by the arrow above – independently of
whether the cutting device is installed in the centre
or outer position.
Put cut-off wheel (1) on spindle.
For cut-off wheels with specified rotating direction (arrow on the cut-off wheel), observe correct
alignment of the cut-off wheel during assembly (for rotation direction of the cut-off wheel, see above).

Push on outer mounting flange (c) so that the curved side points southwards, i.e. away from the cut-off
wheel.
Push on wheel (b) and turn in cut-off wheel attachment screw (11).
Insert blocking pin (a) entirely into the blocking opening (12) and firmly tighten (30 Nm [22.1 ft·lbf]) the
cut-off wheel 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 cut-off wheels with an inner bore of 20 mm.
For proper installation of cut-off wheels with a 1" inner bore, the spindle adapter disk is required that
is included with the delivery of the power tool.
The spindle adapter disk ensures correct fit of the 1" cut-off wheel on the spindle.

Installation of cut-off wheels with 1" inner bore
takes place according to chap. 5.1 as of page 16.
After applying the cut-off wheel on the spindle,
however, the spindle adapter disk (e) must be
put on the spindle (f) additionally.
Put the spindle adapter disk (e) onto the spindle
so that it inserts between spindle and inner bore
of the cut-off wheel.
The support area of the spindle adapter disk
must point outwards in the installed condition,
i.e. away from the spindle.
The correct orientation of the spindle adapter
disk is mandatory to directly connect the plane
inner area to of the outer mounting flange to the
cut-off wheel. Only this warrants secure
attachment of the cut-off wheel.
Application of the outer mounting flange and all
following steps must be performed again
according to chap. 5.1.
For cut-off wheel removal, 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. Chap. 5.4, page 18
Insert blocking pin (a) entirely into the cut-off wheel blocking opening (12) to block the spindle.
Unscrew cut-off wheel attachment screw (11).
Remove wheel (b) and outer mounting flange (c) (also see chap. 5.1).
Remove cut-off wheel from the spindle. For cut-off wheels with a 1" inner bore, the spindle adapter disk
also must be removed from the spindle.
Put the outer mounting flange back onto the spindle so that the curved side points outward.
Put on wheel (b) and turn in the cut-off wheel attachment screw (11) again. Chap. 5.1.
Insert blocking pin (a) entirely into the blocking opening (12) and firmly tighten (30 Nm [22.1 ft·lbf]) the
cut-off wheel 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 wheel guard (2) can be rotated forward and
backward in a limited area.
For adjustment of the wheel guard, the power tool
must be put securely on the ground. 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 wheel guard
adjustment (3), rotate the wheel guard accordingly.
To keep sparks and particles away from the user,
the wheel guard always must be rotated forward as
far as the working situation permits.
If the separating device has been installed in the outer position, ensure when adjusting the wheel
guard that the water supply line is not clamped and that contact between the cut-off wheel and
water supply line in operation is excluded.
Danger to health!
Direct skin contact with gasoline and breathing in of gasoline fumes must be excluded.
The high-performance two-stroke engine of this power tool requires an oil-gasoline mix in the combustion
chamber (oil and gasoline = fuel mix).
Models CP512-300 and CP514-350
Models CP512-300 and CP514-350 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 gasoline or lead-free super
gasoline (octane number 92 RON)
Branded 2-stroke engine oil corresponding to the
standard ISO-L-EGD or JASO FD
Store the fuel mix no longer than 3 weeks.

0.100 l [3.38 oz] 5 l [169 oz]
0.200 l [6.76 oz] 10 l [338 oz]
Instead of a self-produced fuel mix, you may also use a pre-mixed special fuel mix for two-stroke motors.
Recommendation: Use the special fuel mix of the brand "Aspen 2-stroke". The special fuel manufacturer's
information must be observed.
Models CP512-300i and CP514-350i with iLube®
Models CP512-300i and CP514-350i are equipped with a fuel tank and an oil tank each that
must be filled according to the specification below
The fuel mix is automatically formed during operation in these models (separate lubrication,
iLube®, Intelligent Lubrication).
Fuel tank (18) for lead-free regular gasoline
or lead-free super gasoline (octane
number 92 RON).
Do not fill any fuel mix into the fuel tank (18)!
Oil tank (19, green cap) for branded 2-stroke
engine oil corresponding to the standard
ISO-L-EGD or JASO FD.
If there is not enough oil in the oil tank, the
power tool will automatically reduce output
even in the lower speed area and will not
reach the speed required for work, which will
be noticed by changed noise generation as
compared to regular operation.
At this point at the latest, oil must be
refuelled.
Fill in operating media (fuel mix or gasoline and oil)
Observe the safety provisions when fuelling up. Fuel up only with the motor switched off.
Clean the fill-in area well.
Put down the motor device so that the fuel tank cap points up.
Unscrew the tank cap.
To avoid contamination in the tank, use a screen funnel if possible.
Fill the tank no farther than to the lower edge of the nozzle.
Screw on the tank cap tightly again until the overturning protection clearly "skips".
After fuelling up, clean any splashed operating medium from the power tool.
Never start or operate the power tool at the site of fuelling.
