Proxxon MICROMOT 230/E Manual De Instrucciones página 16

Always ensure your own safety!
Despite its compact size, the Micromot 230/E
is an electric tool that harbours a certain level
of risk. Always ensure that the mains plug is
disconnected when checking the device, du-
ring cleaning or when changing the operational
tools or collet chucks!
Attention!
• Never work without safety glasses.
• Wear a protective mask if large amounts of
dust or harmful dusts accumulate.
• 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 clam-
ping. 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 concentricity.
• 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 fi rmly and securely in
the collet!
• Do not work with damaged, bent or worn
bits and cutters! Make sure the tools are in
perfect 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
diameters 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 damage and severe injuries!

5.1 Adjusting the operational tools (Fig. 2)
A collet chuck suitable for a shaft diameter of
2.4 mm is fi tted ex works to the spindle collet
holder. This is the preferred diameter for Prox-
xon operational tools.
Always ensure that the correct collet is used
corresponding to the shaft diameter! Never use
operational tools with a shaft diameter which does
not correspond to the inside diameter of the collet!
Do not tighten the sleeve nut if a collet without
an operational tool is inserted in the spindle!
All operational tools should be clamped as short
as possible. Excessively protruding shafts can
bend easily and contribute to poor concentricity.
Caution!
Disconnect the mains plug!
1. Press the lock button 1
2. Rotate the spindle with the sleeve nut 2
slightly while pressing the lock button si-
multaneously until it engages in the depres-
sion on the spindle.
3. Loosen the sleeve nut
4. Remove the operational tool 3 if necessary
and insert a new one in the collet hole
5. Tighten the sleeve nut 2 while depressing
the lock button.
