5.3 Working with the device

Caution:
Never work without safety glasses.
Do not work with damaged grinding disks
or bent shafts.
Please note:
A correct and uniform speed achieves a high grin-
ding performance, not excessive contact pressure.
The following rule of thumb governs selection
of the speed:
Small milling cutters / pins = high speed,
large milling cutters / pins = low speed.
Caution:
Secure the workpiece during work!
In addition to enabling more pleasant and
effi cient working, this also reduces the risk of the
workpiece fl ying about! Please note: A workpiece
fl ying out can cause injuries! Use a vice or
suitable clamping fi xture to hold the workpiece!
Warning:
It is imperative that electric tool recoil be
avoided!
Factors such as
• the incorrect speed for the work in hand
• selection of the wrong operational tool
• excessive contact pressure
• incorrectly clamped tools
• carelessness during work
can cause the operational tool to seize, catch
and block. The reaction torque may result in an
uncontrolled acceleration of the electric tool or
workpiece in this context which may pose a risk
to the person operating the tool! It is imperative
that this operating condition be avoided. Please
note that operational tools can break, and their
parts fl ying about represent a risk! Risk of injury!
Selecting the speed:
A correct and uniform speed achieves a high
grinding performance, not excessive contact
pressure.
The following rule of thumb governs selection
of the speed:
Small milling cutters / pins = high speed,
large milling cutters / pins = low speed.
1. Activate the device with the switch 1 (Fig. 1) and
set the right speed for the work on the knob 2.
2. Fig. 4 illustrates two typical ways of holding the
MICROMOT 230/E. Ensure that you hold the
device fi rmly during work to enable controlled
guiding of the rotating operational tool. Avoid
covering the ventilation slots during this! In the
event of overheating, deactivate the device and
allow to cool for a few minutes.
5.4 Maintenance, cleaning and care
Caution:
Disconnect the mains plug prior to every
adjustment, maintenance measure or repair!
Note:
Every device is dirtied by dust when working with
wood. Cleaning is therefore essential. To ensure
