● Never put down the power tool until the diamond cutting discs have come
to a complete standstill. Rotating diamond cutting discs can make contact with
the surface on which you put down the tool, causing you to lose control of the
power tool.
● Do not leave the power tool running while you are carrying it. Your clothing
could accidentally get caught in the rotating diamond cutting discs and the diamond
cutting discs could penetrate your body.
● Clean the air vents of your power tool regularly. The motor fan draws dust
into the housing and a heavy accumulation of metal dust can cause electrical
hazards.
● Do not use the power tool near to infl ammable materials. Sparks could ignite
these materials.
● Do not use diamond cutting discs that require liquid coolants. The use of
water or other liquid coolants can cause an electric shock.
● Only allow trained persons to use the power tool. Apprentices may only use
the power tool when they are over 16, when this is necessary for their training
and when they are supervised by a trained operative.
● Children and persons who, due to their physical, sensory or mental abilities
or lack of experience and knowledge are unable to operate the power tool
safely may not use this power tool without supervision or instruction by a
responsible person. Otherwise there is a risk of operating errors and injuries.
● Only use approved and appropriate marked extension leads with a suffi cient
cable cross-section. Use extension leads up to a length of 10 m with cable
cross-section 1.5 mm², from 10 – 30 m with cable cross-section 2.5 mm².
Recoil and appropriate safety instructions for diamond
slitting and cutting machines
Recoil is the sudden reaction to a sticking or blocked diamond cutting disc. Sticking
or blocking leads to abrupt stopping of the rotating diamond cutting discs. This
accelerates the power tool uncontrollably in the opposite direction to the diamond
cutting discs at the blocking point. If, for example, a diamond cutting disc sticks in
the workpiece or blocks, the edge of the diamond cutting disc immersed in the
workpiece can jam and the diamond cutting disc could break out or cause a recoil.
The diamond cutting discs then move towards or away from the operator depending
on the direction of rotation of the diamond cutting discs at the blocking point. Diamond
cutting discs can also break in the process. Recoil is the result of improper or incor-
rect use of the power tool. It can be prevented by suitable precautions as described
below.
● Hold the power tool securely and move your body and arms into a position
in which you can intercept the recoil. Always use the additional handle to
have the greatest possible control over recoil forces or reaction torques
when running up. The operator can control recoil and reaction forces by suitable
precautions.
● Never move your hand close to the rotating diamond cutting discs. These
could move over your hand in the case of recoil.
● Avoid the area in front of and behind the rotating cutting discs. The recoil
propels the power tool in the opposite direction to the movement of the diamond
cutting discs at the blocking point.
● Work very carefully in the area of corners, sharp edges etc. Prevent diamond
cutting discs from bouncing off the workpiece and jamming. The rotating
diamond cutting discs tend to jam at corners, sharp edges and when they bounce
off. This causes loss of control or recoil.
● Do not use a chain or toothed saw blade. Such tools frequently cause a recoil
or loss of control of the power tool.
● Avoid blocking of the diamond cutting discs or too high a pressure. Do not
make excessively deep cuts. Overloading of the diamond cutting discs increases
the stress on them and their susceptibility to jamming or blocking and therefore
the risk of recoil or breaking of the grinding body or breakage of the diamond
cutting discs.
● If the diamond cutting discs jam or you interrupt your work, switch the tool
off and hold it steady until the diamond cutting discs come to a standstill.
Never try to pull the still rotating diamond cutting disc out of the cut as this
could cause recoil. Find and eliminate the cause of the jamming.
● Do not switch the power tool back on as long as it is in the workpiece. Let
the diamond cutting disc reach full speed before carefully continuing the
slitting or cutting process. Otherwise the diamond cutting discs might stick,
jump out of the workpiece, cause recoil and/or break.
● Support boards or large workpieces to reduce the risk of recoil due to
jammed diamond cutting discs. Large workpieces can sag under their own
weight. The workpiece must be supported on both sides of the diamond cutting
discs both near to the cut and at the edge.
● Be especially careful with "pocket cuts" in existing walls or other areas
hidden from view. The entering diamond cutting discs can cause recoil when
cutting into gas or water pipes, electric cables or other objects.
Other safety instructions for diamond slitting
and cutting machines
● Only use the power tool in connection with a suitable safety vacuum cleaner/
dust extractor. When working with mineral building materials, e.g. concrete,
steel-reinforced concrete, all types of masonry, all types of screed, natural stone,
12
a high degree of mineral dust containing quartz is produced which is harmful to
the health. Inhalation of quartz fi ne dust is harmful to the health. The Directive
89/391/EEC on the taking of measures to improve the safety and health protec-
tion of employees at work obliges the employer to carry out an appropriate risk
assessment at the employees' place of work, to determine and evaluate the dust
load that can occur and to determine the necessary protective measures. The
German technical ruling for hazardous substances TRGS 559 "Mineral Dust"
defi nes in Appendix 1 that work with slitting and cutting machines must be clas-
sifi ed in exposure category 3 if the effectiveness of the extraction has not been
proven. In accordance with EN 60335-2-69 a penetration level of < 0.1 % is
prescribed for sucking health hazardous dusts with an exposure limit/work place
limit (AGW) of > 0.1 mg/m³. When slitting and cutting mineral building materials
at least one safety vacuum cleaner/dust extractor or dust class M should there-
fore usually be used in order to effectively extract the harmful dusts from machines.
Observe the national regulations: You are expressly reminded that, in many
countries, additional regulations regarding the safe use of such vacuum cleaners
for clearing up and disposal of health hazardous dusts are imposed by the national
industrial health and safety authorities, water board and similar authorities.
● Always use a safety vacuum cleaner/dust extractor with permanent auto-
matic fi lter cleaning. Slitting and cutting produce large volumes of dust which
contaminate the fi lter of the safety vacuum cleaner/dust extractor without perma-
nent automatic fi lter cleaning to such an extent that the suction performance is
reduced considerably. The produced dust is then sucked off inadequately and
the diamond slitting and cutting machine is overloaded. In addition, the diamond
cutting discs and the power tool can be damaged.
● Observe the manufacturer's specifi cations of both electrical devices before
connection the diamond slitting and cutting machine to the appliance socket
of the safety vacuum cleaner/dust extractor. Power tools could be damaged
if they are not used properly.
● Check the areas concerned for concealed supply lines with a suitable fi nder
before slitting. Slitting can damage or sever gas or water pipes, electric cables
or other objects. Damaged gas pipes can cause explosions. Damaged water
pipes and electric cables can damage property or cause electric shocks. If you
do damage a water pipe, make sure that no water gets into the motor.
● This power tool is not intended for use by persons (including children) with limited
physical, sensory or mental abilities or lack of experience and knowledge unless
they have been instructed in the use of the power tool a person responsible for
their safety and are supervised by such a person. Children must be supervised
to ensure that they do not play with the power tool.
● Never let the power tool operate unattended. Switch off the power tool
during longer work breaks, pull out the mains plug and remove all hoses/
plugs. Electrical devices can cause hazards which lead to material damage or
injury when left unattended.
● Check the power cable of the power tool and extension leads regularly for
damage. Have these renewed by qualifi ed experts or an authorised REMS
customer service workshop in case of damage.
● Never use the power tool in an explosive environment. The power tool gener-
ates sparks when in use which could ignite dust and gases.
● Only use diamond cutting discs with a metal body in accordance with EN
13236.
● Secure the workpieces to be machined against being fl ung away.
● Diamond cutting discs get very hot during work. Let them cool down before
touching or removing.
