Kickback is a sudden reaction to a pinched or
snagged rotating wheel,sanding band, brush
or any other accessory. Pinchingorsnagging
causesrapid stallingofthe rotating accessory
which in turn causes the uncontrolledpower
tooltobeforced in the direction oppositeofthe
accessory’s rotation.
Forexample,ifanabrasive wheelissnagged
or pinchedbythe workpiece, the edgeofthe
wheel thatisentering into the pinch point can
dig into thesurface of thematerial causing the
wheeltoclimb outorkickout.Thewheelmay
eitherjumptoward or away from the operator,
dependingondirectionofthe wheel’smove-
mentatthe pointofpinching. Abrasive wheels
may also break under theseconditions.
Kickback is theresult of power tool misuse
and/or incorrect operating procedures or con-
ditions and canbeavoidedbytakingproper
precautionsasgiven below.

The PROXXON drilling and milling machine MI-
CROMOT 50/E is the ideal tool for precise
drilling, milling, grinding, polishing, brushing,
rust removal, engraving, chasing and cutting.
For hobby electronics, model making, precision
mechanics, jewellery shops, opticians, arts, tool
and mould making.
For marking tools and cameras.
It can be used on steel, non-ferrous metals,
glass, wood, minerals and ceramics.
The drill spindle is supported in a precision ball
bearing which eliminates any play.
Excellent handling because of the pen-type
grip.
- 14 -
The machine is reliably driven by a high torque
motor. Type 50/E is fitted with an electronic
speed regulator.

Attention:
• Never press the lock button while the device
is operating.
• Depending on the collet size, bits and cutters
may have a shaft diameter of max. 3.2 mm.
• Insert the tools are far as possible when
clamping. Ensure that the shaft of the tool
does not stand out more than 30 mm from the
collet. Excessively protruding shafts can
bend easily and contribute to poor concen-
tricity.
• Do not in any case use bits and cutters with
an arbour length of more than 55 mm!
• When using collets, always make sure that
the collet chuck and the utilised tool have the
same shaft diameter! The arbour of the tool
must be seated firmly and securely in the col-
let!
• Do not work with damaged, bent or worn bits
and cutters! Make sure the tools are in per-
fect condition. Damaged or worn tools can
break and cause injuries!
• When storing the bits and cutters, make sure
they are reliably protected from damage!
• A correct and consistent speed achieves a
high grinding performance, not excessive
contact pressure!
• By tendency: Bits and cutters with smaller di-
ameters require higher speeds than those
with a larger diameter.
• Attention: You absolutely must observe the
permissible maximum speed of the bits and
cutters! The tool can break when the maxi-
mum permissible speed is exceeded. Flying
parts can cause
Attention!
Disconnect mains plug before changing tools.
1. Turn the spigot nut (Fig. 2) gently while
pressing the locking knob until it engages.
2. Open the clamping jaw and change the tool.
(:=6492B4?3?308,.3490
1. Push the non-reversible plug into the power
unit.
2. Switch the machine on or (Fig. 1) and set
the correct speed with the button .
Note:
Pressing hard does not achieve good results
when grinding. Use the correct speed and
maintain it.

3. Fig. 3 shows two typical methods for holding
MICROMOT 50. When working, ensure that
the tool is held firmly in order to guide the ro-
tating application tool in a controlled manner
without thereby blocking the ventillation slots.
4. If the unit overheats, switch it off and allow it
to cool for a few minutes.
The electronic speed regulation works only with
non-stabilized power units (e. g. all PROXXON
power units). If connected to a battery, the unit
will only run at max. speed.

Please do not dispose of the device in domestic
waste! The device contains valuable sub-

Every device is dirtied by dust when working.
Cleaning is therefore essential. To ensure a
long service life, however, the machine should
be cleaned with a soft cloth or brush after each
use.
Mild soap or other suitable cleaning agent may
be used in this context. Solvents or cleaning
agents containing alcohol (e.g. petrol, cleaning
alcohols, etc.) should be avoided, since these
can attack plastic casings.
The apertures required for cooling the motor
must always be kept free of dust and dirt.
