3.3 Milling cutters
Always unplug the tool from the mains before
changing cutters!
Do not exceed the maximum speed specified on
the tool and/or keep to the speed range. Cracked or distorted
cutters must not be used.
We recommend that milling cutters with diameters over
55 mm should not be used with this machine.
3.2 Clamping collet changing
- Loosen clamping collet until it releases from motor spindle
(fig. 2.1).
- Take locking nut by means of clamping collet from motor
spindle.
- Pull clamping collet out of locking nut. Push new clamping
collet into locking nut until it locks (fig. 2.2).
- Put locking nut into motor spindle by means of clamping
collet. Hand-tighten locking nut a few turns.
Do not tighten the collet nut until a milling cutter has been
fitted!
3 Machine construction
Always disconnect the plug from the power
supply before making any adjustments to the router or
installing or removing any accessory!
3.1 Electronics
The router OF 2000 E/1 has solid shaft electronics with the
following functions:
Smooth start-up:
The electronically controlled smooth start-up facility enables
start-up of the machine without jerks and requires a lower
start-up current.
Speed regulation:
Using the electronic speed control (1.1) the motor speed can
be continuously adjusted from 12 000 and 22 000 rpm. The
table beside offers a guide to the correct electronic setting
for various materials. The settings are naturally infinitely
variable.
Constant speed:
The selected motor speed is electronically maintained to a
constant level. By this means a uniform cutting speed is
achieved.
Do not work with the OF 2000 E/1 if the
electronic control is defective since this may lead to excessive
speeds. A defect in the electronic control is indicated by the
absence of a smooth run-up, a higher noise level at idle or
the fact that no speed control is possible.
