4.3 Tool change

Danger
The maximum permissible speed
(indicated on the tool) must not be
exceeded!
The operating speed must not
exceed the maximum speed
indicated on the tool.
Pay attention to the correct
direction of rotation!
Clamp the tool so that it cannot
become loose during operation.
The tightening torque must be at
least 20 Nm.
The blades must touch neither
each other nor the clamping
pieces.
Pay attention to cleanliness when
changing tools. The clamping
surfaces must be free of dirt.
Check the tool clamping at regular
intervals
Checking the tool clamping
•
Unplug the power plug before checking the tool
clamping.
•
Put down the machine as shown in Figure 10.
•
Press the push-button 2 (Fig. 2) and pull the
locking lever 19 upwards. The shift lever 8 is
now locked.
•
Open the retractable saw guard 28 by means of
plunge lever 1.
•
Lock the tool with position indicator 29. Position
the position indicator 29 in Pos. B (Fig. 10).
•
To check the tool clamping: Firmly tighten the
cylinder head screw 15 (at least 20 Nm).
Tool change
•
Pull the plug before changing tools.
•
Put down the machine as shown in Figure 10.
•
Press the push-button 2 (Fig. 2) and pull the
locking lever 19 upwards. The shift lever 8 is
now locked.
•
Open the retractable saw guard 28 by means of
pre-feed lever 1.
•
Lock the tool with position indicator 29. Position
the position indicator 29 in Pos. A (Fig. 10).
•
Use the hexagon screw driver 23 to unscrew the
cylinder head screw 15 counter clockwise;
detach flange 27 and milling head 26.
•
Clean the tool spindle and clamping surfaces of
adhering chips and dust. Attach the tool. When
doing so ensure that both drive pins on the
spindle engage in both bores on the tool. If any
dirt gets between the components or if the
components are not correctly fitted, there is a
risk that the milling head 26 may come loose
during machining despite this procedure.
•
Lock the tool with position indicator 29. Position
the position indicator 29 in Pos. B (Fig. 10).
•
Insert the cylinder head screw 15 and the flange
27 and tighten clockwise with hexagon screw
driver 23 (at least 20 Nm).
•
Caution: After the check and tool change,
remove position indicator 29 and the hexagon
screw driver 23 from the tool.
•
Close the retractable saw guard 28 and press
down the locking lever 19 (Fig. 2).

Danger
Always pull the power plug before
making changes or adjustments.
Install and remove the cutters in
accordance with the instructions in
the operating manual. Utmost
caution is mandatory!
Ensure clean clamping surfaces.
Observe the specified tightening
torques! The clamping screws must
be tightened only with the tools
provided or with a tool of the same
dimensions. No striking tools,
levers, extensions or other tools
may be used.
All blades must always be fitted in
order to prevent imbalance.
The milling head (scope of supply) is equipped with
12 interchangeable carbide indexable cutting inserts.
Resharpening is not possible. When blades are blunt,
the carbide indexable cutting inserts are turned or
