breakage of parts and any other condition that may affect the power tool's
operation. If damaged, have the power tool repaired before use. Many
accidents are caused by poorly maintained power tools.
f) Keep cutting tools sharp and clean. Properly maintained cutting tools with
sharp cutting edges are less likely to bind and are easier to control.
g) Use the power tool, accessories and tool bits etc. in accordance with these
instructions, taking into account the working conditions and the work to
be performed. Use of the power tool for operations different from those intended
could result in a hazardous situation.
5) Service
a) Have your power tool serviced by a qualified repair person using only
identical replacement parts. This will ensure that the safety of the power tool
is maintained.
Special safety instructions for diamond slitting and
cutting machines
WARNING
a) The power tool's protective hood must be fitted securely and set so that
maximum safety is achieved, i. e. the smallest possible part of the diamond
cutting disc is open to the operator. You and persons nearby should stand
outside the area of the rotating diamond cutting discs. The protective hood
should protect the operator against fragments and accidental contact with the
diamond cutting discs.
b) Only use diamond cutting discs for your power tool. Just because you can
fit a cutting disc to your power does not automatically guarantee its safe use.
c) The admissible speed of the diamond cutting disc must be at least as high
as the maximum speed specified on the power tool. Accessories which turn
faster than the admissible speed can break and fly about.
d) Diamond cutting discs may only be used for the recommended possible
applications, e.g.: Never grind with the side surface of a diamond cutting
disc. Diamond cutting discs are intended for removal of material with the edge
of the disc. Lateral forces on the grinding body can bread it.
e) Always use undamaged clamping flanges and spacer discs of the right size
and shape for the diamond cutting discs that you have chosen. Suitable
flanges and spacer discs support the diamond cutting discs and therefore reduce
the risk of breakage of the diamond cutting discs.
f) Outer diameter and thickness of the diamond cutting discs must match the
dimension specifications of your power tool. Diamond cuttings discs of the
wrong size cannot be adequately shielded or controlled.
g) The diamond cuttings discs, clamping flange and spacer discs must fit
exactly onto the drive shaft of your diamond slitting and cutting machine.
Diamond cutting discs which do not fit the power tool's drive shaft exactly rotate
unevenly, vibrate very strongly and can lead to loss of control.
h) Do not use damaged diamond cutting discs. Check the diamond cutting discs
for splitting and cracks every time before using. If the power tool or a diamond
cutting disc falls to the ground, check whether the diamond cutting disc has been
damaged. Only use undamaged diamond cutting discs. When you have checked
and fitted the diamond cutting discs, you and persons nearby should stand outside
the area of the rotating diamond cutting discs and let the power tool run for one
minute at maximum speed. Damaged diamond cutting discs usually break in this
test time.
i) Wear personal safety equipment. Use full face protection, eye protection
or protective glasses depending on the application. Where appropriate,
wear a dust mask, ear defenders, protective gloves or special aprons which
keep small grinding and material particles away from you. The eyes should
be protected against flying foreign bodies which occur in different applications.
Dust masks and respirators must filter the dust produced in the application.
Prolonged exposure to loud noise can lead to loss of hearing.
j) Make sure that other persons are standing well away from the area you are
working in. Everyone who enters the work area must wear personal safety
equipment. Fragments of the workpiece or broken diamond cutting discs can
fly off and cause injury even outside the direct work area.
k) Only hold the power tool by the insulated handles when performing work
where the diamond cutting discs can come into contact with concealed
electric cables or its own power cable. Contact with a live cable can also put
metal parts of the power tool under voltage and lead to electric shock.
l) Keep the power cable away from rotating diamond cutting discs. If you lose
control over the tool, the power cable could be severed or caught and your hand
or arm could get into the rotating diamond cutting disc.
m) 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.
n) 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.
o) 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.
p) Do not use the power tool near to inflammable materials. Sparks could ignite
these materials.
q) Do not use diamond cutting discs that require liquid coolants. The use of
water or other liquid coolants can cause an electric shock.
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.
a) 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.
b) Never move your hand close to the rotating diamond cutting discs. These
could move over your hand in the case of recoil.
c) 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.
d) 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.
e) Do not use a chain or toothed saw blade. Such tools frequently cause a recoil
or loss of control of the power tool.
f) 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.
g) 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.
h) 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.
i) 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.
j) 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,
a high degree of mineral dust containing quartz is produced which is harmful to
the health. Inhalation of quartz fine 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"
defines in Appendix 1 that work with slitting and cutting machines must be clas-
sified 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.
● Check the areas concerned for concealed supply lines with a suitable finder
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.
● Check the power cable of the power tool and extension leads regularly for
