BRIEF DESCRIPTION
This machine is designed for use with rotary milling heads for milling slots, edges, profiles and rough-edged holes, from a firm base, in wood, synthetic and light construction materials, and for milling operation with a copier. By employing the correct milling heads and using slow speeds, non-ferrous metals may also be milled.
BEFORE USING THIS TOOL
Make sure the mains voltage is correct: it must be the same as that on the specification label. Machines with 230-V can also be connected to a 220-V mains supply.
The machine is put into operation using the lever A, pressing it upwards (I-ON) will start the machine. Pressing it towards the base (0-OFF) will stop it.
Speed adjustments. Constant electronic performance
The control electronics allow continuous pre-setting of the revolutions and impact frequency to adapt the machine to the type of material to be worked on. Adjustment is made using the speed adjustment switch L, which has 6 positions to regulate the speed.
The higher the number, the greater the speed and impact energy. The range of settings from “1” (low power) to “6” (full power) makes the tool very flexible and adaptable to different applications.
The constant speed control maintains the pre-set number of revolutions and impact frequency.
Check the speed adjustment label N for the desired working speed.
 |
The values in this table are for guideline purposes only. The required revolutions will depend on the material and working conditions. It is recommended that these be established by carrying out tests with the machine. |
MILLING HEAD SELECTION AND INSTALLATION
1.1. Milling head selection
Depending on the materials to be worked, the following milling head qualities may be selected:
• High-performance, fast-cutting steel milling heads (HSS): suitable for soft materials, such as soft woods and plastic.
• Milling heads with hard metal blades (HM): suitable hard and abrasive materials, such as hard woods and aluminum.
WARNING! The milling heads that are employed must be officially approved in accordance with the maximum revolutions defined for the respective tools. The milling head shaft diameter should match the inside diameter of the tool-holder (locking clip).
1.2. Milling head installation
WARNING! The mains cable must be removed from the socket before any adjustments are made to the machine. It is recommended that protective gloves be worn when installing or removing milling heads.
- To install the milling head, press the spindle lock of shaft B until it coincides with the shaft planes.
- A 22-mm spanner should be used to loosen clip fixing nut D in an anticlockwise direction.
- Insert the milling head so that the shaft enters the clip by a minimum of 20 mm (shaft length).
- Tighten the clip fixing nut D with the spanner and release the clip-carrier shaft support lever B.
PRECAUTION: Do not tighten clip fixing nut D without a milling head inserted into the clip.
ADJUSTING MILLING OPERATION DEPTH
WARNING! The milling operation depth adjustment must only be performed with the machine switched off. The milling operation depth may be adjusted according to the work to be carried out.
The machine is fitted with a depth stop E, the upper surface of which is used in conjunction with the graduated scale M fine control of the milling operation depth. For deep cutting operations, it is recommended that several passes be made, with a reduced chip thickness. Operate the fixing lever H and slowly push the upper section of the machine against the depth stop E. Lock the machine by releasing the fixing lever H.
Pressing locking button G will unlock the depth stop E, providing a simple method of stop adjustment.
Fixing lever H should be pressed to immobilize the machine at a determined working height.
To prevent running off-load, rotate the depth adjustment handle C until the desired return distance is obtained.
With the stepped stop F it is possible to perform the milling operation in three stages. To start, adjust the milling depth to the lowest position of stepped stop F. Then the milling operation can be carried out at the higher positions.
PRECAUTION: For large diameter cuts, it is recommended that the depth is set to minimum and to continue cutting in stages. When commencing the work, the milling head should be slowly entered until the desired depth is obtained and then allowed to advance, always supporting the machine with two hands.
OPERATING INSTRUCTIONS.
PRECAUTION: The machine should always be unplugged before making any adjustments to the machine.
WARNING! The actual milling operation should always be made in the direction opposite to the milling head rotation direction (according to Fig. 4). Advancing the machine in the opposite direction could cause it to rebound and lead to an accident.
1.1. Milling
1. The milling depth should be adjusted in accordance with the previous description.
2. Switch on and place the machine over the work piece, firmly held in place.
3. Carry out the milling operation with a uniform advancing movement.
4. On completing the milling operation, push the upper section of the machine upwards and switch it off.
1.2. Milling with parallel stop

Once both wing screws V have been loosened, the parallel stop can be re-adjusted using fine adjustment S. Adjust the desired length with the divisions with inches and millimeters marked on the side stop I.
Stop strip S may be used to increase the parallel stop contact surface.
1.3. Milling with the copier bushing
Copy bushing U enables edges to be milled on the workpiece in accordance with a pattern or template. Installing the copier bushing In order to use the copier bushing U, it must be installed on the lower section of support plate P from above and fixed in place with the screws.
WARNING! It is essential to ensure correct installation position.
1.4. Milling straight or profiled edges
When milling straight or profiled edges, without the parallel stop, the milling head must be fitted with a guide shaft or ball bearing (optional accessory).
The operating machine should be brought into contact with the work-piece from the side, until the milling head guide shaft or ball bearing is seated against the edge of the work piece. The machine must be guided with both hands, always perpendicular to the surface, along the entire length of the work-piece edge. Excessive applied pressure could damage the work-piece edge.
DUST EXTRACTION
WARNING! Always make sure that the tool is switched off and unplugged before fitting or removing any dust extraction device.
Dust extraction keeps the workplace clean, prevents dust build-up in the air and facilitates waste elimination. These milling machines are fitted with adapter, which can be coupled to a universal vacuum aspirator or other dust suction device.
CAUTION: A suction extractor should always be used that has been designed in accordance with the applicable directives in relation to dust emission when milling wood. The flexible hoses of conventional vacuum cleaners fit directly onto the dust extraction nozzle.
Installing the dust suction adapter
PRECAUTION: Before installing the suction adapter K, press the fixing lever H so that the upper section of the machine ascends to the upper position.
In order to install the dust suction adapter K, it should be inserted in the square opening on the base plate P until it fits fully into place, and then fixed using the wing screws R, which are located on both sides of the adapter K.
In order to maintain optimum chip extraction, the suction adapter K should be periodically cleaned. The aspirator should be suitable for the material being worked.
A special aspirator must be employed in those cases where dry harmful or carcinogenic dust is produced. In situations where prolonged wood operations are performed or machines are used industrially with materials that produce dust that is harmful to health, the machine must be connected to a suitable external aspiration device.
