turn. To set the slitting depth, move the depth stop (5) to the desired position
and tighten with the depth stop clamping screw (20).

2.6. Dust extraction

WARNING WARNING
Inhalation of the dusts produced when slitting and cutting is harmful to the
health. Observe the national regulations. It is recommended to use a safety
vacuum cleaner/dust extractor of dust class M. Observe the operating instruc-
tions of the safety vacuum cleaner/dust extractor.
Push the suction nozzle adapter (16) onto the suction nozzle (15) on the REMS
Krokodil 125 so that the greatest possible distance of the pushed on suction
hose from the contact plate is achieved (Fig. 1).
No adapter is required for the suction nozzle on the REMS Krokodil 180 SR.
Only use safety vacuum cleaners/dust extractors with permanent automatic
fi lter cleaning. 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.

2.7. Fixing the workpiece
Workpieces which are slit or cut loosely must be rigidly fi xed and secured
against being fl ung away.
2.8. Note on static
Before beginning work, make sure that the building static is not negatively
affected by the slitting or cutting work; consult the building management or a
static engineer if necessary. Slitting work in supporting walls may be subject
to national regulations. These regulations must be observed.
3. Operation
Use eye protection
Use ear protection
Suitable safety vacuum cleaners/dust extractors, a respirator and disposable
overalls must be used for work which could produce health hazardous dusts.
Observe the national regulations.
REMS Krokodil 125 and REMS Krokodil 180 SR are fi tted with a safety switch
with lock (8). This enables the drive unit to be shut down at any time and
prevents unintentional staring of the drive unit. The safety switch with lock must
fi rst be pushed in the direction of the mains lead and then pressed on the REMS
Krokodil 125. On the REMS Krokodil 180 SR fi rst the locking button on the side
of the switch handle (1) and then the safety switch must be pressed.
In order to simplify handling and to avoid damage, REMS Krokodil 125 and
REMS Krokodil 180 SR must be equipped with multi-function electronics with
electronic speed control or speed regulator. The multi-function electronics
perform the following functions:
● Electronic start-up current limiting reduces the inrush current and therefore
allows operation on a 16 A fuse.
● Soft start for protecting the drive unit and jolt-free starting after switching on.
● Limiting of the idle speed to reduce noise and preserve the motor and gear.
● Overload protection of the motor depending on the thrust pressure. The
motor current and thus the speed of the drive machine is reduced to a
minimum before overloading of the drive unit due to too high a thrust pres-
sure on the diamond cutting discs or blocking. However, the drive unit does
not switch off. If the thrust pressure is reduced, the speed of the drive unit
increases again. This process does not damage the drive unit even if it is
repeated several times. If the motor remains at standstill despite reducing
the thrust pressure, however, the drive unit must be switched off and the
diamond cutting discs may have to be re-engaged.
3.1. Slitting
REMS Krokodil 125
Use suitable safety vacuum cleaners/dust extractors with permanent automatic
fi lter cleaning. Hold the REMS Krokodil 125 by the switch handle (1) and holding
handle (3) and set the contact plate (9) against the surface to be machined.
Make sure you have a safe footing and enough room for the drive unit, safety
vacuum cleaner/dust extractor, suction hose and user. Safety vacuum cleaner/
dust extractor. Switch on the REMS Krokodil 125 at the switch handle. To do
this, fi rst push the safety switch with lock in the direction of the mains lead and
then press it. When the power tool has reached full speed, press the REMS
Krokodil 125 onto the surface with even thrust pressure. The diamond cutting
discs penetrate the surface. On reaching the slitting depth, push the REMS
Krokodil 125 forward against against the direction of the arrow (14) because otherwise
the cutting disc could lift uncontrolled out of the slit. Make sure that the diamond
cutting discs do not twist/jam. After fi nishing the slit, switch off the REMS Krokodil
125 and wait until the diamond cutting discs have come to a complete standstill.
Do not lift off the surface until the drive unit is at a standstill. Switch off the
safety vacuum cleaner/dust extractor.
CAUTION CAUTION
Diamond cutting discs get very hot. Let them cool down before touching or
removing.
Make sure that the suction hose of the safety vacuum cleaner/dust extractor
does not kink and impair the dust extraction. Also make sure that no fragments
of stone or other objects jam in the suction nozzle (15) and/or suction hose.
Empty the dust bag of the safety vacuum cleaner/dust extractor early and clean/
renew the fi lter regularly. Observe the operating instructions of the safety vacuum
cleaner/dust extractor.
After slitting, a ridge remains between the slits. This can be broken out with a
slitting chisel (part no. 185024).
REMS Krokodil 180 SR
Use suitable safety vacuum cleaners/dust extractors with permanent automatic
fi lter cleaning. Hold the REMS Krokodil 180 SR by the switch handle (1) and
holding handle (3) and set the contact plate (9) against the surface to be
machined. Make sure you have a safe footing and enough room for the drive
unit, safety vacuum cleaner/dust extractor, suction hose and user. Safety vacuum
cleaner/dust extractor. Switch on the REMS Krokodil 180 SR at the switch
handle. To do this, fi rst press the lock button on the side of the switch handle
