Safety precautions before setting up the plate bevel

The plate bevelling machine can be operated only in the horizontal position. Secure the workpiece.

Checking the properties of the workpiece.

The surface of the workpiece must meet the following requirements. The surface must be even and free of any burn marks, slag, weld seams and the like. Remove surface roughness before starting to mill.

Adjusting the milling head

Place the machine on its upper side (power supply cable). Release the locking mechanism (2) on both sides of the machine. Set the milling angle required. The milling angle can be read on the scale (1). Tighten the locking mechanism (2) on both sides of the machine.

Setting the bevel width

Place the machine on its upper side (power supply cable). Release the locking mechanism (1). Set the bevel angle you want by turning the adjusting screw (3). The bevel width can be read on the scale (2). Tighten the locking mechanism (1).

Fitting the guide roller for milling plate

Fit the plate (3) as shown in the picture. Secure the guide rollers (2) in the bore (1) with the washer and nut.

Milling with the plate bevel

Proceed as follows for milling:

‹ Align the workpiece to be machined horizontally and secure it.
‹ Fit the guide roller according to the application required; see the section Fitting the guide roller.
‹ Set the milling angle and the bevel width; see the sections Setting the milling angle and Setting the bevel width.
‹ Plug the machine into the mains socket.
‹ Place the machine on the workpiece so that the cutter does not engage the workpiece.
‹ Switch the machine on; see the section Switching on the plate bevelling machine.
‹ Slide the plate bevelling machine slowly and evenly from right to left in the direction of the arrow. The tool works against the direction of travel.
‹ Switch the plate bevelling machine off; see.
‹ Unplug the machine from the mains socket.

CAUTION

Possible property damage if the machine is used improperly!

►Follow the instructions below to prevent damage.

►Lay the connecting cable so that it cannot be caught by the running machine.

NOTE

Follow the instructions below.

►Never engage the material with the indexable inserts while the machine is at a standstill.
►Maintain an even feed.

Using the plate bevel

The following procedure shows how the plate bevelling machine is operated:

Switching the machine on

‹ Turn the main switch (1) to position "1".
‹ Press the green push button (2) to switch the milling motor on. The yellow indicator light (4) comes on.

Switching the machine off

‹ Press the red push button (3) to switch the milling motor off.
‹ Turn the main switch (1) to position "0".

Restarting after an overload

‹ To start the machine again after an overload, press the red push button (3) first and then the green push button (2).

NOTE

► In the event of a temporary overload the red indicator light (5) flashes.

► In the event of a continuous overload the red indicator light (5) comes on and the milling motor is switched off.

Changing the tool (inserts) of the plate bevelling machine

WARNING: Risk of injury!

► Do not use damaged, dirty or worn tools (inserts).

► Change the tools (inserts) only when the machine is switched off and at a standstill. Unplug the machine from the mains socket.

► Use only tools, adapters and accessories that match the machine.

Indexing the insert

Place the machine on its upper side (power supply cable ).
‹ Remove the screw (2).
‹ Remove the housing (1).
‹ Remove the clamping screw (3), index the insert and tighten the clamping screw again.
‹ Repeat the procedure for all the inserts of the cutter.
‹ Refit the part and tighten the screw (2).
