For your safety
Read all safety warnings and instructions.
Failure to follow all safety warnings and in-
structions may result in electric shock, fire
and/or serious injury.
Do not use this power tool before you have
thoroughly read and completely understood
this Instruction Manual, the enclosed “Gen-
eral Safety Instructions”, instructions for bat-
tery packs and chargers.
Keep all safety instructions and information for
future reference. Pass on your power tool only to-
gether with these documents.
Please also observe the relevant national indus-
trial safety regulations.
Safety instructions for wire saws
Do not reach into the area of the saw wire when the
tool is switched on.
Only make the saw cuts using the handle provided
for this purpose and at the same time secure the
workpiece (insulation material) by hand.
Only use suitable materials.
If the impeller tensioner is already at the end stop,
the impellers must be switched.
If the cutting speed decreases, the saw wire should
be replaced.
A damaged or worn saw wire must not be used.
If the saw wire jams in the workpiece (insulation
material), switch off the motor immediately. Before
switching on again, the saw wire must be able to
rotate freely again.
Before operating the wire saw, check that it is sta-
ble and that all machine parts are assembled cor-
rectly, especially all protective devices. Also check
that the saw wire and impellers are in good condi-
tion and that the saw wire is sufficiently tensioned.
Additional safety instructions
Particles generated when working with this ma-
chine may contain substances that can cause can-
cer, allergic reactions, respiratory diseases, birth
defects or other propagation defects. Some of
these substances include: mineral dust (from min-
eral wool, aerated concrete or similar), styrene, etc.
The risk depends on for how long the user or near-
by persons are exposed to the substance.
This dust must not be allowed to enter your body.
Do the following to reduce exposure to these sub-
stances:
- Ensure good ventilation of the workplace
- To protect your health, wear a suitable
protective mask.
- Always wear protective goggles to protect
against sanding hazards.
- Connect the electric power tool to a suitable ex-
traction system.
- Sweeping or blowing stirs up dust.
- Vacuum or wash the protective clothing. Do not
blow, beat or brush.
Collect the generated particles at the source, avoid
deposits in the surrounding area.
Always use an antistatic suction hose with the
power tool. A slight electric shock may cause you to
panic briefly and become distracted, which may re-
sult in an accident.
switch off the machine immediately when the
safety clutch responds and if the saw wire breaks!
Do not overload the motor for a long period. Engine
noise should be regular (not wave-like). Unsteady
engine performance can be perceived acoustically.
Take a break when the machine is heated up
strongly and let it cool down again. To that let the
motor idle at top speed for some time.
Don’t bend the flexible drive shaft!
Only use original Rokamat saw wire. Foreign mate-
rials are not suitable for the saw wire speed and
applications of the wire saw and could tear.
Emission levels
NOTE! Values for the A-weighted sound pressure
level and for the total vibration values can be found
in the “Technical specifications” table at page 5.
The vibration emission level given in this infor-
mation sheet has been measured in accordance
with a standardized test and may be used to com-
pare one tool with another. It may be used for a
preliminary assessment of exposure.
CAUTION! The indicated measurements refer to
new power tools. Daily use causes the noise and vi-
bration values to change.
The declared vibration emission level represents
the main applications of the tool. However, if the
tool is used for different applications, with differ-
ent accessories or poorly maintained, the vibration
emission may differ. This may significantly in-
crease the exposure level over the total working
period. However, if the tool is used for different ap-
plications, with different accessories or poorly
maintained, the vibration emission may differ. This
may significantly decrease the exposure level over
the total working period.
CAUTION! The noise produced during work
may damage your hearing.
Wear ear protection!

handle [1-4] pressed - the saw wire starts moving.
Release the button [4-1] again to stop the saw wire.
Foot switch (optional)
Instead of the button [4-1] on the handle, the wire
saw can also be started with the foot switch (op-
tionally available).
First, the foot switch must be connected to the
socket of the motor housing [1-5]. Then press the
foot switch to start the wire saw.
If the foot switch is no longer actuated, the saw
wire comes to a standstill again.
Adjusting the cutting angle
Mitre cuts [6]: Loosen the quick release top [6-1]
and bottom [6-2], adjust the cutting bow [1-2] to
the desired angle (see mitre indicator), fix the quick
release [6-1 and 6-2] again.
Bevel cuts [7]: To move the support angle [7-3],
loosen the star grip screw [7-4], set the desired an-
gle (see scale on the support plate [1-3]) and
tighten the star grip screw [7-4] again.
Width stop [7]
For quick cutting repetition, the desired dimension
can be set on the support angle using the end stop
[7-2].
To do this, loosen the star screw [7-1], move the end
stop [7-2] to the desired position and tighten the
star screw [7-1] again.
Width stop [10-A]
Move out the cutting bow [1-2]. Loosen the star grip
screw [10-2] at the top and bottom and slide the
depth limit to the desired dimension (see scale on
the cutting bow). Then retighten the star grip
screws [10-2]. Now move the cutting bow [1-2] to
the end stop and loosen the fixing bolts [10-1] at the
top and bottom by turning them, push them to the
right and engage them by turning them again.
Sawing insulating material
Damage to the wire saw!
Always push the insulation material through
from left to right!
Place the insulation material on the support plate
[1-3] and make all necessary adjustments. Activate
the wire saw (see "Starting the wire saw"). The cut-
ting bow [1-2] can be moved using the handle [1-4].
It is possible to cut both by pushing and pulling the
cutting bow [1-2]. In addition, if the cutting bow
[1-2] is fixed (see "Depth limit"), the insulation ma-
terial can also be pushed from left to right in order
to cut it horizontally.
Changing the saw wire [9]
Over time, the tension of the saw wire may de-
crease. In this case, perform the following steps:
AInsert the enclosed Allen wrench [9-1] into the
opening [9-2] of the top cover [1-1] and turn the
clamping screw inside counterclockwise. This
allows the spring to tension the saw wire again.
BThen tighten the clamping screw clockwise
again.
Changing the saw wire [10]
ALock the cutting bow [1-2] using the star grips
[10-2] between a height of 60-100 mm and ex-
tend the fixing bolt [10-1] (see “Width stop”).
BLoosen the screws of the top and bottom co-
vers [1-1 and 1-9] and remove the covers.
C Use the enclosed Allen wrench to loosen the
clamping screw [10-3] to be able to move the
clamping device.
DPut (worn) saw wire [10-4] over the impellers
to remove it.
Install the new saw wire in reverse order.
