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 EN 60745:
Sound pressure level
LPA = 75 dB (A)
Uncertainty
KPA = 3 dB (A)
Sound power level
LPA = 86 dB (A)
Uncertainty
KPA = 3 dB (A)
The noise measurement was done without tool at idling speed.
2.5 Scope of delivery
Milling motor MM-1000 complete with:
1 collet ø 3,175 mm OZ8A 401E DIN 6388A
1 open-ended spanner AF 17
1 operating manual
1 folder "Safety instructions"
2.6 Use according to intended purpose
The milling motor is intended for permanent installation
in guiding machining systems with ø 43 mm clamping
collar. Tools are selected depending on the materials
to be processed and the capacity of the feed drives.
Please take into account the milling motor capacity at
maximum tool diameter and anticipated machining
depth.
We exclude the use as hand-guided power tool.
The appliance is not designed for non-stop industrial
operation. The maximum speed can be referenced in
chapter 2.3 “Technical data”.
The milling motor is considered an incomplete
machine. The incomplete machine may only be
commissioned once it has been determined that the
machine that is to be incorporated into the incomplete
machine complies with the provisions of the current
and valid Machinery Directive.
Please also note the corresponding warranty
conditions for the milling motor and any supplementary
appliances.
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 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 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!
General instructions:
- 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 protection devices stipulated
for the respective operating sequence and do not
effect any modifications on the machine that could
impair safety.
- Damaged cables or plugs must be immediately
replaced.
- Avoid sharp bends in the cable. Especially when
transporting and storing the machine, do not wind
the cable around the machine.
Do not use:
- Damaged tools or tools that have changed their
shape.
- Blunt tools due to the excessive engine load.
- Tools that are not suitable for the tool speed during
idling.
Instructions on the use of personal protective
equipment:
- Always wear ear protectors during work.
- Always where a dust mark during work.
- Always wear protective goggles during work.
Instructions on operation:
- Do not reach into the danger zone of the tool with
your hands.
- Examine the workpiece for foreign objects.
Instructions on service and maintenance:
- Regular cleaning of the device 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 commissioning make sure that the mains
voltage complies 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.
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.
•Push the new tool into the tool holding fixture up
to the limit stop.
•Check the tool’s seat.
•Spindle 1 is locked when the tool is clamped.
•Tighten union nut 3 with the open-ended
spanner.
5Operation
5.1 Initial operation
Personnel entrusted to work with the machine must be
made aware of the operating instructions, calling
particular attention to the chapter "Safety instructions".
This operating manual only deals with the milling motor
and not with the installation situation. Please take note
of any other operating manuals.

-7-
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.
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 switch the machine on
again and continue working at a reduced feed speed.
With the setting wheel X(Fig. 2) you can continuously
adjust the speed between 4,000 rpm and 25,000 rpm.
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.
6Service and maintenance
Danger
Pull the power plug during all
service work.
STEPCRAFT machines are designed to be low in
maintenance.
Replace the carbon brushes at the latest after 125 -
150 operating hours.
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 STEPCRAFT 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.
7Troubleshooting
Danger
Determining the causes for existing defects and eliminating these always
requires increased attention and caution. Pull the mains plug beforehand!
Some of the most frequent defects and their causes are listed in the following chart. In case of other defects,
contact your dealer or the MAFELL customer service.
