Dust/Chip Extraction
Dust from materials such as lead-containing coatings,
some wood types, minerals and metal can be harmful to
one’s health. Touching or breathing-in the dust can cause
allergic reactions and/or lead to respiratory infections of
the user or bystanders.
Certain dust, such as oak or beech dust, is considered car-
cinogenic, especially in connection with wood-treatment
additives (chromate, wood preservative). Materials
containing asbestos may only be worked by specialists.
As far as possible, use a dust extraction system suitable
for the material.
Provide for good ventilation of the working place.
It is recommended to wear a P2 filter-class respirator.
Observe the relevant regulations in your country for the
materials to be worked.
Prevent dust accumulation at the workplace. Dust can
easily ignite.
Connecting the Dust Extraction (optional accessory)
The dust extraction 19 is intended only when working with the
sanding plate 12; it is not of use in combination with other ap-
plication tools.
For sanding, always connect the dust extraction.
To mount the dust extraction 19 (accessory), remove the
application tool and the depth stop 14.
Slide the dust extraction 19 all the way over the tool holder 9
onto the collar of the power tool. Turn the dust extraction to
the required position (not directly under the power tool).
Press shut the clamping lever 20 to fix the dust extraction.
Plug the tool sleeve of the vacuum hose 17 onto the vacuum
connection 18. Connect the vacuum hose 17 to a vacuum
cleaner (accessory).
An overview for connecting to various vacuum cleaners can be
found on the graphics page.
The vacuum cleaner must be suitable for the material being
worked.
When vacuuming dry dust that is especially detrimental to
health or carcinogenic, use a special vacuum cleaner.
Operation
Starting Operation
Inserting the battery
Note: Use of batteries not suitable for the machine can lead to
malfunctions of or cause damage to the power tool.
Insert the charged battery 3 into the handle until it can be felt
to engage and faces flush against the handle.
Switching On and Off
To start the machine, push the On/Off switch 2 forward so
that the “I” is indicated on the switch.
The electronic soft starting feature limits the torque upon
switching on and increases the working life of the motor.
The constant electronic control keeps the stroke rate almost
constant under no-load or load conditions and ensures a uni-
form working performance.
To switch off the machine, push the On/Off switch 2 toward
the rear so that the “0” is indicated on the switch.
To save energy, only switch the power tool on when using it.
The LED improves visibility in the immediate work area. It is
automatically switched on and off with the power tool.
Do not look directly into the work area illumination –
your sight can be temporarily degraded!
Preselecting the Orbital Stroke Rate
With the thumbwheel for preselection of the orbital stroke
rate 5, you can preselect the required orbital stroke rate, even
during operation.
The required stroke rate depends on the material and the
working conditions and can be determined through practical
testing.
When sawing, cutting and sanding harder materials, e.g.,
wood or metal, it is recommended to work with orbital stroke
rate “6”; for softer materials, such as plastic, orbital stroke
rate “4” is recommended.
Working Advice
Wait until the machine has come to a standstill before
placing it down.
Before any work on the power tool, remove the battery.
Note: Do not cover off the venting slots 7 of the machine while
working, as this reduces the working life of the machine.
While working with HCS tools make sure that the covering of
the tools is undamaged.
Operating Principle
Due to the oscillating drive the application tool/accessory
oscillates up to 20000 times per minute at 2.8°. This allows
for precise work in narrow spaces.
Work with low and uniform application
pressure, otherwise, the working perfor-
mance will decline and the application tool
can become blocked.
While working, move the machine back and
forth, so that the application tool does not
heat up excessively and become blocked.
Sawing
Use only undamaged saw blades that are in perfect
condition. Bent or dull saw blades can break, negatively
influence the cut, or lead to kickback.
When sawing light building materials, observe the
statutory provisions and the recommendations of the
material suppliers.
Plunge cuts may only be applied to soft materials, such
as wood, gypsum plaster boards, etc.!
Before sawing with HCS saw blades in wood, particle board,
building materials, etc., check these for foreign objects such
as nails, screws, or similar. If required, remove foreign
objects or use BIM saw blades.
