2.4 Emissions

The values stated are emission levels. Although there is a correlation between emission and imission level, it

cannot be reliably derived from this whether additional precautions are necessary. Factors influencing the

current immission level existing at the workplace comprise the duration of exposure, the room characteristic,

other source of noise, etc. such as e.g. the number of machines and other adjacent machining operations. In

addition, the permissible immission level may differ from country to country. This information is nevertheless

suitable for providing the machine user with an improved assessment of the hazard and risk.

2.4.1 Noise emission specifications

Noise emission values determined according to DIN EN ISO 3744:

Sound pressure level LPA = 71 dB (A)

Uncertainty

= 3 dB (A)

Sound power level LPA = 82 dB (A)

Uncertainty KPA = 3 dB (A)

The noise measurement was done without tool at idling speed.

2.7 Residual risks

Danger

Even if used in accordance with its intended purpose and despite conforming with the

safety instructions, residual risks caused by the intended use will always remain.

- Breakage of the rotating tool.

- Breakage of the tools and risk of the tools or parts of them being hurled away.

- Touching live parts with the housing open and the mains plug not removed.

- Hearing can be impaired when working for long periods without ear protectors.

- Emission of hazardous or potentially explosive dusts (all types) during longer lasting operation without

extraction. Please note the safety data sheet of the material to be machined.

3Safety instructions

Danger

Always observe the following safety instructions and the safety regulations applicable in

the respective country of use!

Allgemeine Hinweise:

- Children and adolescents must not operate this machine. This rule does not apply to young persons

receiving training and being supervised by an expert.

- Never work without the portal system guards into which the power tool is inserted and that are prescribed for

each operation. Do not make any changes to the portal system and the power tool that could compromise

safety.

- Damaged cables or plugs must be immediately replaced. Replacement may only be carried out by

STEPCRAFT in order to avoid safety hazards.

- Avoid sharp bends in the cable. Do not wind the cable around the power tool especially when transporting

and storing the power tool.

- The use of the power tool with water or conductive liquids is prohibited.

- Always where a dust mark during work.

- Always wear protective goggles during work.

Instructions on operation:

- Do not reach with your hands into the danger zone of the tool.

- Examine the workpiece for foreign objects.

- Monitor the speed. If an uncontrolled speed increase or speed jump occurs, the power supply must be

switched off immediately.

Instructions on service and maintenance:

- Regular cleaning of the power tool is an important safety factor.

- Only original STEPCRAFT spare parts and accessories may be used. Otherwise, the manufacturer will not

accept any warranty claims and cannot be held liable.

4Setting / Adjustment

4.1 Mains connection

Prior to initial operation, make sure that the mains voltage agrees with the operating voltage stated on the

machine's rating plate.

4.2 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.

4.2.1 Tool clamping by means of collet

The spindle 1 (Fig. 1) of the milling and grinding motor is equipped with a precision collet 2 (Fig. 1) to hold

the tools. The spindle lock is triggered by the locking button 4 and facilitates tightening and loosening of

the union nut 3 (Fig. 1).

-8-

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 or AF 25.

- Pull off the tool to the front.

- Push the new tool into the tool holding fixture up to the limit stop.

- Check the tool’s seat.

- Spindle 1 (Fig. 1) is locked when the tool is clamped.

- Tighten union nut 3 with the open-ended spanner.

4.2.2 Quick tool clamping

The collets must snap into the clamping nut. Only then, a correct clamping of the end mill and, above all, a

rerelease of the collet are possible.

5Operation

5.1 Initial operation

Personnel entrusted to work with the power tool must be made aware of the operating manual, calling

particular attention to the chapter “Safety instructions”.

This operating manual only deals with the power tool and does not take the installation situation into account.

Please take note of any other operating manuals.

5.1.1 Switching on

Push the power switch 5 (Fig. 1) forward until it engages. If the power tool is connected to the mains voltage,

the setting wheel X (Fig. 2) lights up in blue (BU) and the power tool accelerates to the previously set speed

after 0.2 s with a soft start. The duration of the soft start depends on the set speed and is approx. 1.2 s at

maximum speed.

5.1.2 Switching off

Push onto the rear end of the power switch 5 (Fig. 1). The switch audibly jumps back to off position. The

lighting on the setting wheel X (Fig. 2) goes out and the motor coasts to a standstill.

-9-

5.2 PV design

With the PV design Y (Fig. 2) you can control the speed via the PV interface and automatically monitor the

remaining runtime in the event of overload.

To protect the user and the connected systems, the PV interface is electrically isolated from the power

supply of the drive train (safety isolation). All signal and operating voltages refer to the reference potential

“GND”.

As soon as the supply pin “UPV” of the PV interface is supplied with voltage in accordance with the

specification, the power tool switches to “portal mode”.

The bottom status table 3 shows all possible control constellations.

5.2.1 Assignment portal connector

All pins on the portal connector are protected against reverse polarity. At voltages above 30 V, continuous

operation with reversed polarity must be avoided as this can lead to failure of the PV interface.

5.3 Speed Specification

With the setting wheel X (Fig. 2) you can adjust the speed continuously. The concrete speed values

of individual stages can be found in the table on page 5 or on the speed sticker on the housing.

Until the motor characteristic is reached, the built-in electronics readjust to the set speed.

5.3.1 Speed setting in PV design

In “portal mode”, the position of the setting wheel X (Fig. 2) for the speed setting is ignored. The speed can

only be changed by the voltage at the pin “US“. If you wish to set the speed by means of the setting wheel

X (Fig. 2), “portal mode” must first be deactivated by switching off the power supply at the pin “UPV“ or by

removing the PV control cable.

The correlation between speed and control voltage is illustrated in formulae (1) and (2).

5.4 Overload protection

Danger

If you carry out any work on the working spindle after the overload protection has

triggered, the mains plug must first be removed.

To protect the power tool, the operating parameters current, speed and temperature are dynamically

monitored and the power tool is switched off if necessary. Shortly before the overload protection is tripped,

the illumination of the setting wheel X (Fig. 2) changes to a permanent red (RD).

To put the power tool back into operation, you must open and close power switch 5 (Fig. 1). The power

tool goes into operation and the illumination of the setting wheel X (Fig. 2) changes to blue (BU).

5.4.1 Optical display of the remaining runtime

Triggering of the overload protection during operation leads to breakage of the milling tool, damage to the

workpiece or even damage to the portal system. You can prevent this by paying attention to the visual

output signals at the setting wheel X (Fig. 2).

As long as the power tool is not overloaded in terms of performance, the setting wheel lights up

permanently in blue (BU).
