4.3 Tool change

Danger
Pull the power plug during all
service work.
Wear protective gloves during a
tool change. The insertion tool can
get very hot during longer operation
and/or the insertion tool's cutting
edges are sharp.
The spindle 1 (Fig. 1) of the milling and grinding
motor is equipped with a precision collet 2 (Fig. 1) to
hold the tools. Tightening and releasing the unit nut 3
(Fig. 1) is made easy with a spindle lock 4.
Proceed as follows for the tool change:

Lock the spindle 1 (Fig. 1) to unclamp the tool
by pressing the locking button 4 (Fig. 1).

Detach union nut 3 with an open-ended spanner
AF 17.

Pull off the tool to the front.

Operation

5.1 Initial operation

Personnel entrusted to work with the machine must
be made aware of the operating instructions, calling
particular attention
instructions".
This operating manual only deals with the milling
motor and not with the installation situation. Please
take note of any other operating manuals.

5.2 Switching on and off


Switching on: Push the switch 5 (Fig. 1)
forward until it engages.

Switching off: Push onto the rear end of the
switch. The switch jumps into off position.
to the chapter "Safety
The built-in electronic system provides for jerk-free
acceleration when the machine is switched on and
under load readjusts the speed to the fixed setting.
In addition, this electronic system reduces the motor
output in case of an overload, i.e. the spindle stops.
Switch the machine off then. Then switch the
machine on again and continue working at a reduced
feed speed.
With the setting wheel X (Fig. 2) you can adjust the
speed continuously. Appropriate speed values at the
different levels can be referenced in the table on page
3.

5.3 Collets

Danger
To protect the thread, only screw
the union nut 3 lightly onto the
spindle 1, but do not tighten when
no tool is inserted. Collet 2 could
get pressed together too much and
be damaged in the process.

Unscrew the union nut 3 with the collet 2 (Fig.
1).

Tilt out the collet 2 to the side.

Service and maintenance

Danger
Pull the power plug during all
service work.
MAFELL machines are designed to be low in
maintenance.
Replace the carbon brushes at the latest after 125 -
150 operating hours. The spare parts can be
referenced in chapter 9.
The ball bearings used are greased for life. When the
machine has been in operation for a longer period of
time, we recommend to hand the machine in at an
authorised MAFELL customer service shop for
inspection.

6.1 Storage

If the machine is not used for a longer period of time,
it has to be carefully cleaned. Spray bright metal parts
with a rust inhibitor.
